We use several types of detection traps, including the glass McPhail, paper Jackson, plastic Japanese Beetle, sticky paper panel traps and sticky delta traps. Most of the traps are specifically designed to attract a particular type of insect.
We noticed and admired your fruit tree(s) while we were working in your neighborhood. If you have a Japanese Beetle or Gypsy Moth trap, it was placed because your ornamental trees, turf, or roses caught our eye.
Please contact us by email or call us at (925) 608-6600.
We typically leave these traps on the property for six weeks or until the fruit is gone. The Japanese beetle trap and the gypsy moth trap are normally placed in May and removed in September. We try not to visit the same property until a full year has elapsed.
The majority of the traps are placed in front yard fruit trees or on trees that hang over a public walkway. We do not enter backyards without leaving a notice in advance or talking to a resident of the property beforehand. If you received a notice but were unable to speak to a Pest Detection Specialist about a trap being placed, please call us with any concerns or special instructions about entering your property.
No, but staff members will be carrying official identification and will be in a marked county vehicle.
Good news! We do not charge for this service. Trapping benefits our agricultural community and all residents with fruit trees and gardens that contain hosts of exotic fruit flies and other pests. Thank you for allowing us the use of your trees/turf/gardens to assist in the early detection of new pests.
Not at all. The trap will function best if you leave it alone. We will service the trap regularly. If you must move the trap, please do not throw it away. Instead, please leave it where we can find and retrieve it.
Some traps are checked weekly, while others are checked bi-weekly. The particular day may change due to holidays or other interruptions of the work schedule.
It depends on which pest, how many are found, and whether it is a male, unmated female, or mated female. A detection will prompt the California Department of Food and Agriculture (CDFA) to place more traps in the area to determine the extent of the infestation. In rare situations, state or county staff might need to take all the fruit off the tree and do some localized pesticide treatments. If this is the case, residents will be informed before their property is treated. If conditions warrant it, a quarantine restricting the movement of the host fruits, vegetables, or plants may be instituted. If this were to happen, CDFA and our department would hold public meetings to explain where the quarantine was located and how it worked in greater detail.
The glass McPhail traps, which contain water with yeast, attract any kind of fly that is in the area, including house flies. The yellow sticky panel trap is also a general trap and may catch non-target insects. The other traps we use contain a specific pheromone that only attracts the male of the target species. From time to time, other insects will wander into the traps and get caught.
No, the traps do not affect the quality or safety of the fruit. In fact, they may actually protect the fruit from being destroyed by an insect pest. Pick, wash and enjoy your fruit as you normally do.
Since McPhail traps are made of glass, they can break. If you find a trap that has fallen to the ground and is broken, please carefully pick up and dispose of the glass in the regular trash as you would with other broken glass. The fluid inside might have a strong odor from the yeast, but the material inside is harmless and can be hosed down with plain water. Panel, Jackson and Delta traps can be picked up and placed back into the tree by the homeowner or resident, although if you do so, please be sure to handle the trap carefully. Panel traps are very sticky, and the cotton wick inside the Jackson and Delta traps has a trace amount of a pesticide used to kill the fly, so please don’t touch them without gloves. You may also contact us and we will immediately make arrangements to rehang the trap.
Yes, they are! However, non-native insects have no natural predators here to keep a population in control. By controlling exotic pests, we are protecting agriculture, gardens, and our environment.
You can help by:
1. Welcoming the detection traps featured on this page.
2. Report any unusual or targeted insects or plant conditions. You can report this to our department, the University of California Master Gardeners of Contra Costa, or the California Department of Food and Agriculture Pest Hotline at 1-800-491-1899.
3. Follow any quarantine restrictions that apply to your property.
4. When returning to California from an out-of-state trip, do not bring back prohibited fruits, vegetables, and other plants with you.
5. Discourage your family and friends outside of California from sending backyard produce or plants in the mail. If you do want to send these things, contact our office so we can help you to determine if you can do it safely. Visit the California Department of Agriculture’s information on bringing plants and animals into California and guide for bringing fruit and vegetables into California (PDF) to find out what is prohibited.
Buchanan Field now has scheduled charter service provided by JSX with daily flights to Burbank, CA. For more information, please visit their website at www.jsx.com.
The Aviation Advisory Committee is one forum for voicing opinions and concerns. The committee typically meets on the second Thursday of each month at the Director of Airports Office at 550 Sally Ride Drive in Concord, CA. Meetings are open to the general public and include a public comment period. You may also email your concern or suggestion to Airports staff by completing an Airports Feedback Form, which may be found on the Noise Management Page.
Buchanan Field is one of only a few airports in California to have adopted a Federal Aviation Administration (FAA) authorized noise ordinance which limits operating hours for flight training and prohibits airplanes that exceed 78 dBA, per FAA Advisory Circular 36-3. Airports staff maintains regular communication with pilots based at Buchanan Field regarding the Noise Management Program, aircraft specific noise abatement procedures, community feedback, and encourages its pilots to avoid flying over neighboring communities whenever possible. The Aviation Advisory Committee (AAC) provides the public a forum for which to voice opinions and concerns on airport matters. Please visit the Buchanan Field Noise Program website under Community Resources on this website for more information.
Once an aircraft has left the ground, it is in Federal Aviation Administration (FAA) jurisdiction. For the safety of both pilots and the community, only the FAA can direct an aircraft to change altitude or flight path and use certain runways. This direction is often based on wind and weather conditions that may vary throughout the day. While Airports staff cannot direct a plane to change direction, communication with pilots regarding community concerns is ongoing. If you notice an aircraft flying objectionably low or loud, we value your feedback. You may submit an Airport Feedback Form, which can be found on the Community Resources: Noise Management page.
Buchanan Field is a federally regulated 24-hour public use facility, so there is no curfew for arrivals or departures. However, the Contra Costa County Airports Noise Ordinance does limit flight training and touch-and-go operations to the to 7:00 AM to 10:00 PM Monday through Friday and 8:00 AM to 10:00 PM on weekends and holidays. In addition, the Ordinance restricts airplanes exceeding 75 dBA, per the Federal Aviation Administration Advisory Circular 36-3, from 10:00 PM to 7:00 AM.
Aviation activity varies depending on weather and economic factors and typically increases in spring and summer months due to the good weather. Buchanan Field averages approximately 120,000 operations (take-off or landings) per year. The peak use of Buchanan Field in the last 30 years was in 1990 when the Airport had over 300,000 operations and was home to a commercial airline and a helicopter flight training school. Annual operations decreased during the recent recession—hitting a 25 year low in 2012—but have rebounded along with the economy. For a graph of operations by year, please click on the Buchanan Field Annual Operations link found on the Buchanan Field (CCR) page of this website.
Airports staff is working on a series of planned informational videos to inform the general public about the benefits provided by Buchanan Field and Byron Airports and encourage pilots and prospective tenants to consider basing their aircraft at the Airports. The first video, Touch Down in the Bay Area, was completed in late 2014 and the second video, Learning to Fly, was completed in 2016. Learning to Fly focused on the process of earning a pilot’s license, and the various services and programs based at Contra Costa County Airports that make that goal easier to attain. Airports staff is also constantly improving the website to improve usability and functionality, including news and event features that users may subscribe to and remain apprised of current issues and events at the Airports. Airports staff has convened the Economic Development Incentive Program, a working group of the Airports’ stakeholders, to help prioritize projects and programs that will best market the Buchanan Field and Byron Airport.
Once an aircraft has left the ground, it is in Federal Aviation Administration (FAA) jurisdiction. Pilots that are flying low and/or unsafe may be reported directly to the FAA Flight Standards District Office (FSDO) by calling (510) 748-0122. You may also notify Airports staff by submitting an Airports Feedback Form. FAA regulations do allow for aerobatic aircraft operations in an area south of the City of Antioch and to the west of the City of Brentwood. While it is unlikely the aircraft are originating from Buchanan Field and/or Byron Airport, Airports staff has responded by sending out notices to all of its tenants at Buchanan Field and Byron Airports requesting that pilots not perform aerobatic operations near residential developments. An outreach was also sent to other Bay Area airports to provide the notice to their tenants of the community feedback Airports staff has received. This is an on-going task, and your sustained input and support is key to this community-wide process.

The "Know Before You Fly" campaign is another informational resource; available at www.knowbeforeyoufly.org.
This ordinance requires new construction of the following building types to be an all-electric building:
The Ordinance defines an all-electric building as a building that has no natural gas or propane plumbing installed within the building, and that uses electricity as the sole source of energy for its space heating (including heating of all indoor and outdoor spaces of the building), water heating (including heating of indoor and outdoor pools and spas), cooking appliances, and clothes drying appliances. An all-electric building may utilize solar thermal pool heating.
Generally, for most building types, all-electric buildings are less costly to build. The service and piping for natural gas infrastructure is often more expensive than installing a building with all-electric equipment.
The California Statewide Reach Code Program has prepared cost effectiveness reports. View the reports on the California Reach Code website
No, Contra Costa County is part of an ever-growing list of over 50 jurisdictions across that State that have adopted similar ordinances to phase out fossil fuels from new buildings.
State policy already indicates a shifting away from fossil fuels as a source of power towards greater use of renewable energy. While County staff are not involved in managing the State’s energy supply or grid infrastructure, multiple State agencies are deeply involved in planning for the State’s future energy needs. These agencies are dedicating tremendous resources and attention to address these concerns.
The State continues to work with utilities to reduce the need for PSPS events. However, such events will likely occur again in the future, subject to weather conditions. Property owners can mitigate their risk of losing power during PSPS events by installing a source of backup power, such as a generator or battery storage.
The ordinance only applies to new construction of buildings that are residential (single-family, multi-family, or detached accessory dwelling units), Hotel, Office, or Retail.
Any permits issued on or after June 1, 2022, for New Construction of all Residential, Retail, Office, and Hotel buildings are required to be All-Electric (no natural gas allowed). Beginning April 1, 2022, building permit applications subject to the ordinance must be designed to be all-electric (no natural gas allowed).
The ordinance does not pertain to any additions, alterations or tenant improvements to any existing buildings, including any attached accessory dwelling units. Additionally, it does not preclude anyone from installing natural gas for any existing buildings, including other allowed ancillary uses to existing buildings, such as pools, spas, or other similar outdoor equipment.
Any proposed development approved for restaurant use would be allowed to install natural gas. However, any retail uses in a proposed commercial development would be subject to the all-electric requirement (no natural gas allowed). This means that in some commercial projects natural gas may be allowed for some uses in the commercial building (i.e., restaurants).
No, emergency backup power can be fossil-fuel operated, if its sole purpose is for emergency backup power.
Yes, new construction of all building types included in the all-electric ordinance are allowed to use solar/thermal heating in their project.
Yes, the following are not subject to the All-Electric Requirements
If the project applicant proposes a new residential home or multi-family building that includes a pool, spa, or other similar outdoor ancillary uses, the project would be required to be all-electric. Under this circumstance, the pool may utilize solar thermal pool heating.
Proposed pools, spas, or other such ancillary uses to any existing residential buildings, including existing residential buildings that were subject to the all-electric ordinance when they were initially constructed, are not subject to the all-electric ordinance.

A list of tax-defaulted properties to be offered for sale is available on the Tax Collector’s website at least 21 days prior to the tax sale. Visit our website regularly for tax sale announcements. Remember--because property owners have the right to redeem their property prior to the sale, the final list of parcels to be offered for sale will not be available until the day of the sale. Auction list sales are final. Updated information on properties that remain in the sale is available at the Tax Collector’s office.
Vacant ("unimproved") land (which accounts for most property offered at our tax sales) usually has no address and therefore its approximate geographic location can be determined through the use of County Assessor plat maps. Exact boundary lines of a property can be determined only by a survey of the property initiated at the purchaser’s expense. "Improved" properties frequently (but not always) will bear a "situs" (street) address, making it quite simple to assess the location. A "situs" (street) address does not mean there are improvements on the property or that the improvements are included in the sale.
Yes. State law dictates that the event of a tax sale must be published three times in successive seven day intervals before the tax sale date in a newspaper, or newspapers of general circulation within Contra Costa County. All parcels in the next tax sale will be advertised in local newspapers, the first publication date being not less than 21 days prior to the date of the sale. These parcels will also be listed on the Tax Collector’s website during the same time period.
Please review the Registration Information handout available in our office or on our web site, www.cctax.us, for additional information and requirements and application deadlines. Prospective purchasers are required to register as a bidder on the GovEase.com.com website. Each bidder will have to electronically sign or fill out any registration documents. In addition, a single $5,000.00 deposit and a $35.00 registration fee is required to get approved to bid in the auction. The registration fee is non-refundable. All deposits and registrations must be received by GovEase no later than the Monday before the date the sale begins. If you need help, you can email email@example.com or call 769-208-5050, ext. 2. Credit cards are not an acceptable form of payment. Registration can be done online at www.GovEase.com. All unused deposits will be refunded by GovEase within seven to ten business days after the sale. Please review the California training articles and videos on the GovEase homepage by clicking on the Tax Sale Bidder Help tab at the top of the page.
No. The tax sale will be conducted online.
The burden is on the purchaser to thoroughly research, before the sale, any matters relevant to his or her decision to purchase, rather than on the county, whose sole interest is the recovery of back taxes.
It is also recommended that bidders consult with the zoning and planning departments of any city within which a particular parcel lies.
ALL PROPERTIES ARE SOLD "AS IS" AND ALL SALES ARE FINAL.
The right of redemption on a tax-defaulted parcel subject to the Tax Collector’s power to sell ceases at the close of business on the last day prior to the date of sale. There is no extended right of redemption in the State of California. Redemption by mail with Certified or Cashier’s Check must be received in our office by the last business day prior to the date of the sale. Our mailing address is Tax Collector, Attn: Redemption, P.O. Box 631, Martinez, CA 94553.
Payment in full by wire transfer or ACH will be required within 24 hours of the close of the auction. No business checks, personal checks or credit cards will be accepted. A 3% Buyers Premium will be included during the live bidding and will reflect in the final purchase price.
Purchasers of property at the tax sale must also pay a Documentary Transfer Tax on the amount of the bid. The tax is based on the rate of $.55 for each $500 or fractional part of each $500 when the bid exceeds $100.
Purchasers of property within the city of Richmond must also pay a City Transfer Tax in addition to the Documentary Transfer Tax. The rate for this city tax is $7 per $1,000 of the purchase price.
(a) Any lien for installments of taxes and special assessments, which installments will become payable upon the secured roll after the time of sale.
(b) The lien for taxes or assessments or other rights of any taxing agency which does not consent to the sale under this chapter.
(c) Liens for special assessments levied upon the property conveyed which were, at the time of the sale under this chapter, not included in the amount necessary to redeem the tax-defaulted property, and, where a taxing agency which collects its own taxes has consented to the sale under this chapter, not included in the amount required to redeem from sale to the taxing agency.
(d) Easements constituting servitude upon or burdens to the property; water rights, the record title to which is held separately from the title to the property; and restrictions of record.
(e) Unaccepted, recorded, irrevocable offers of dedication of the property to the public or a public entity for a public purpose, and recorded options of any taxing agency to purchase the property or any interest therein for a public purpose.
(f) Unpaid assessments under the Improvement Bond Act of 1915 (Division 10 [commencing with Section 8500] of the Streets and Highways Code) which are not satisfied as a result of the sale proceeds being applied pursuant to Chapter 1.3 (commencing with Section 4671) Part 8.
(g) Any federal Internal Revenue Service liens which, pursuant to provisions of federal law, are not discharged by the sale, even though the tax collector has provided proper notice to the Internal Revenue Service before that date.”
(h) Unpaid special taxes under the Mello-Roos Community Facilities Act of 1982 (Chapter 2.5 [commencing with Section 53311] of Part 1 of Division 2 of Title 5 of the Government Code) that are not satisfied as a result of the sale proceeds being applied pursuant to Chapter 1.3 (commencing with Section 4671) of Part 8.”
Note: A title search initiated at the prospective purchaser(s)’ expense should reveal any liens or encumbrances on a property in the tax sale.
Title is vested in the name of the actual purchaser at the sale as provided at the time of registration to the GovEase.com website. If title is to be vested differently, we require a notarized letter from the individual you are acting as an agent for, stating the manner in which title is to be vested.
The County assumes no liability for any other possible liens, encumbrances or easements, recorded or not recorded. When property is sold at tax sale on which the IRS holds a tax lien, the United States has the right of redemption for 120 days from the date of such sale (26 USC Sec. 3712(g) and 7425(d)). The IRS will pay the actual amount paid for the property by the bidder, plus interest at 6% per annum from the date of sale, plus the expenses of sale that exceed any income received from the property.
Property Tax Reimbursement
The Franchise Tax Board's Homeowner Assistance program provided property tax relief to persons who were blind, disabled, or at least 62 years old, and met certain minimum annual income thresholds. However, the state budget deleted funding for this Program that once provided cash reimbursement of a portion of the property taxes that you paid on your home. For more information, call the Franchise Tax Board at 1-800-852-5711.
Property Tax Postponement
The State Controller's Property Tax Postponement program allowed persons who are blind, disabled, or at least 62 years old, and meet certain minimum annual income thresholds to postpone their property taxes. However, the state budget eliminated the Property Tax Postponement Program. For more information, call the State Controller's Office at 1-800-952-5661 or 916-327-5587.
Effective January 1, 2006, developers of single-family subdivisions of five lots or more are granted an automatic builder’s exclusion upon recording the subdivision map. To be granted the Builder’s Exclusion on fewer than five single-family lots or on other types of property, you must submit a letter requesting the exclusion prior to or within 30 days of the start of new construction on land development and/or improvements. The parcels for which you are requesting an exclusion must be intended for resale, and for no other purpose than that incidental to resale, such as a model home. In short, this means that builders should submit a request for an exclusion as soon as they buy raw land intended for development.
Recommendations: Apply for the exclusion as soon as the land is purchased. Apply for the whole tract. If builder's exclusion is granted on the parent parcel and the parcel splits there is no need to reapply. Builders should be aware that after the exclusion is granted they are still responsible for payment of supplemental tax bills based upon the purchase of land for development, and for payment of annual secured tax bills based on the value of land and new construction complete or incomplete on January 1 of each year. Builders owning parcels protected by a builder's Exclusion are also cautioned that should they begin using these parcels for a purpose other than resale, such as rentals, they are required to notify the Assessor's Office of this fact within 45 days after such non-resale use begins.
Requests for Builder's Exclusions should be addressed to: Gus S. Kramer, Assessor ASR Division 2530 Arnold Drive, Suite 400 Martinez, CA 94553 For further information call (925)313-7400.
When a sale or transfer occurs, the Assessor's Office receives a copy of the deed and determines if a reappraisal is required under State law. If it is required, an appraisal is made to determine the new market value of the property. The owner is then notified of the new assessment and has the right to appeal the value.
The transfer of property between husband and wife does not require a reappraisal for property tax purposes. This includes transfers resulting from divorce or death. In addition, a refinancing will not cause a reappraisal.
As a result of recent State legislation, the purchase of a mobile home park by the residents will not cause a reassessment. Property taxes will remain at their current level and be prorated among the spaces.
Under State law, if the January 1 market value of your property falls below the assessed or taxable value as shown on the tax bill issued in the same year (i.e., January 1, 2009 and tax bill fiscal year 2009/10 issued September 2009), the Assessor’s Office is required to lower the assessment. This type of property tax relief generally applies to recently purchased property. Appeals may be filed between July 2 and November 30 for the annual roll. For supplemental events, or escaped assessments, the appeal must be filed within 60 day of the mailing date of the notice. Appeal forms can be obtained and must be filed with the Clerk of the Board. For more information, call (925) 655-2008.
The issue of non-payment of taxes needs to be addressed with the Tax Collector's office. Their phone number is (925) 957-5280 or visit
The taxes are calculated by the Auditor-Controller. Property tax rates vary by area. In Contra Costa County the tax rates average approximately 1.1% of the property's taxable value. For instance, if the taxable value is $10,000, the property taxes could be about $110. Contact the Auditor-Controller at(925) 646-2236 or
Please visit the Planning department for a permit.
Building Permits are required before you erect, construct, enlarge, alter, repair, move, improve, remove, convert or demolish any building or structure. See Section 106.2 of the California Building Code for further exemptions. The link below provides a summary of the exemptions. Watch the How to Video about Work Exempt from Permits for more information. Exemption from the permit requirements shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of any County code or ordinance. Please call us if you have any questions 925-655-2700.
Please visit one of our offices to have your plans reviewed and permit issued.
Permits may be issued only to property owners, licensed contractors, long-term lessees or their certified agents.
That depends on the scope of the work. Permits that can be issued by fax or mail are generally issued on the same day. Some projects require approval either by the County Planning Division or City Planning Department and other agencies before the Building Inspection Division can proceed with the plan review. Then depending on the scope of the project, it may take anywhere from one day to several weeks depending on the amount of structural and non-structural review required. Minor projects that are usually issued either that day or the next day are: •Minor in-kind repairs due to damage caused by fire, termites, or deterioration •Minor interior alterations with no structural work •Plumbing, mechanical, or electrical repairs, change-outs, or alterations •Mobile homes Major Projects that may take up to several weeks to review are: •Changes in building use or occupancy •Major additions (greater than 50 percent of the existing structure) •Major structural work (seismic upgrades, major repairs, etc.) •Major tenant improvements •New residences in subdivisions with established master plans •Compliance with Title 24 energy documentation requirements
A permit may be obtained for a replaced water heater after it has been installed in emergency situations. Normally, a water heater will only require a final inspection. Please call us for more information 925-655-2700.
To request a Records Research, please download the Records Request form or call 925-655-7213 to request the form. The completed form can be emailed to the Records division or faxed in to 925-674-7244. All requests for plan copies must have permission from the owner and licensed professional before they may be reproduced.
Your license is current for the license year in which you obtain it and must be renewed each July 1 as long as you are in business. A 25% penalty charge and 18% per annum interest rate are imposed if license tax is not paid on time.
Every business must at least meet zoning and building requirements to ensure that its business category and site are compatible before signing any leases and moving in. Check with the County Zoning/Planning Department to make sure you locate your business at an address where it is allowed and that it does not heavily impact the neighborhood or require special parking consideration.
Also, if your business name is anything other than your surname or has more than one owner -- a partnership, association, or company -- you may need to file a fictitious business name with the County Clerk's Office, (925) 335-7900. Should you accidentally "infringe" upon another business, you may face legal action and will have to pay to re-file your Business License -- and that gets expensive. So, it is a good idea to do this before you apply for the Business License.
A copy of the fictitious name certification is required with your business license application.
A copy of your current State Contractor’s License is required with your business license application.
Applications may be filed in person at the Treasurer - Tax Collector's office or by mail at: Treasurer-Tax Collector's Office Business License Tax Division 625 Court Street, Room 100 Martinez, CA 94553-0063
Yes. However, it is your responsibility to obtain a renewal license whether or not a renewal notice is received.

Sometimes channels or time on LO channels can be "leased." Leased Access is another way local channels are used.
Educational Access channels are usually used by schools to show educational television, telecourses, or information about local schools and resources. Here in Contra Costa County, Educational Access television is provided by the Contra Costa Educational Television Consortium.
Government Access television allows local City and County governments to serve their communities by providing information about local resources, services, and emergencies. Coverage of local City Council and Board of Supervisors meetings, allow the public to see how local government runs and how its elected leaders make decisions.
County staff respond to code enforcement complaints according to the impact of the violation on the community. Situations that appear to pose a serious risk to health and safety as well as disabled access complaints are given high priority. Others are pursued in the order in which they are received. For most code complaints a Courtesy Letter is sent out informing the property owner that they may have a code violation and to contact the code enforcement officer. For serious health and safety, disabled access and work being done without a permit, a code enforcement officer is sent out to ascertain if a violation exists and to request remediation. This is initiated with a Notice to Comply letter.
A complaint about a possible code violation is made by letter, e-mail, fax or in person. Please be prepared with specific information such as the address of the property, details of the situation and the length of time you have observed the situation. Contact us at 925-655-2710 or Toll Free at 877-646-8314. You may submit a complaint form online. You may also submit a complaint form by printing and submitting by fax, mail or drop off to the office.
You should contact the code enforcement officer to discuss the possible violation. The county is looking for voluntary compliance and is willing to work with you to resolve the issue.
You may call us at 925-655-2710 or toll free at 877-646-8314. You can also submit a Code Enforcement complaint online.
In many cases the individual responsible for the code violation is given the opportunity to correct the situation and comply with current codes without a penalty. If the correction is not made, the individual may be subject to fines and other penalties.
Once a code enforcement officer makes a site visit and a Notice to Comply letter has been issued, the county ordinance provides that a code enforcement fee shall be charged equal to two times the amount or $300 minimum for building, plumbing, mechanical and electrical permit fees. Zoning violation clearance requires a minimum of a $300 fee. A fee of $150 per trip will be charged until compliance is met. The fees and expenses are additive to the building permit and/or zoning fee.
Contra Costa County Ordinance 720-2.006 states “no one shall maintain weeds exceeding 18 inches in height.” It is not only an eyesore but can promote fire danger. The fire department takes the lead in fire hazard abatements (tall grass) and Code Enforcement the lead in public nuisances (weeds and overgrown brush).
No. Portable canopies located in driveways, though widely popular, are not permitted in Contra Costa County. The two fundamental reasons are wind loads and zoning requirements. Moderate winds have blown these structures down and into roadways presenting unreasonable hazards. To meet the wind load resistance they must be securely affixed to the ground which makes them permanent structure by definition. Zoning requirements prohibit the first 20’ of the front yard from having permanent structures installed prohibiting the canopies.
Converting attached garages into living space is a common practice and can be achieved in many cases. Careful planning must be used to meet numerous requirements. The first obstacle is replacing the parking spaces some where on your property that the original garage provided. The Planning Division will review your plans to ensure the parking spaces are restored and in an appropriate location. The second typical obstacle is meeting the building code requirements. Living space must meet more stringent requirements than a garage. Examples are a moisture barrier for the concrete floor and walls, insulation in the walls and ceiling, heating, electrical upgrades, light and ventilation requirements to name just a few. Normally a homeowner hires an architect to assist in this process to provide cost effective solutions to these and other issues.
Yes. Contra Costa County Ordinance 84-68.1404 allows the storage of boats and recreational vehicles on private property; however 90% of the mass must be screened from public view. Screening may be accomplished by landscaping, fencing, or an intervening building. It is important to note that this rarely can be achieved when the vehicle or vessel is in the front driveway.
Yes. Contra Costa County Ordinance 720-2.006 prohibits garbage cans being left in public view from a street, highway or private road for more than 36 hours.
In general, there are no restrictions for construction working hours within Contra Costa County. Occasionally, as a conditional of approval, the Planning Division may restrict days and times of construction to a permit approval. The Planning Division 925-655-2705 retains the information about specific sites.
Illegal dumping is a serious problem in the County. Dumping on public land or streets should be reported to the Contra Costa County Sheriffs Department immediately. Do not approach someone dumping illegally, record the license plate number and vehicle information if it can be done safely and immediately report it to the police. Dumping on private land should be reported to Code Enforcement at 925-655-2710 or Toll Free at 877-646-8314.
Graffiti is a serious problem that creates visual blight and diminishes property values. Graffiti is a crime and should be reported to the Contra Costa County Sheriffs Department. Occasionally, the markings are gang related and promote violence in the area. The quick removal of the graffiti is one of the most effective deterrents of additional “tagging”. Additionally you may contact the following departments; for publicly owned property such as street signs, sidewalks, and freeway underpasses marked with graffiti should be reported to the Public Works department at 925-313-7000. Privately owned property such as the sides of buildings, and fences should be reported to Code Enforcement 925-655-2710 or Toll Free at 877-646-8314.
Abandoned vehicles on public streets, highways and private roads should be reported to the Sheriffs Department. Abandoned vehicles on private property should be reported to Code Enforcement 925-655-2710 or Toll Free at 877-646-8314. In order for the vehicle to be removed from private property it must be determined inoperable. This means it must move under its own power and generally complete.
Registered heritage trees, trees that provide land stability, are of a protected species or size, or provide visual screening/and or privacy are subject to tree removal permits. Each tree removal permit is subject to individual consideration and approved or denied on a case by case basis by the Planning Division. Some factors used to determine tree removal approval include hazardous situations, number of trees on a property, damage to existing structures, and reasonable development. Prior to removing any tree on your property, you are advised to contact the Planning Division at 925-655-2700 to verify your tree does not require a removal permit.
Storage sheds, tool sheds and play houses that have a foot print of less than 120 square feet do not require a building permit however do have other restrictions. . In the event you bring a utility such as electricity or water to the structure, or enclose mechanical equipment such as a well or pool pump, permits are required. Electrical, plumbing and mechanical permits are required for a structure that may not require a building permit. Sheds and playhouses are not permitted to be located in the property setbacks. This is a required open space that separates properties around the perimeter of the property. Setback distances vary based on property zoning. The Application and Permit Center 925-655-2700 will help you determine the set back requirements of your property.
Code Enforcement processes complaints regarding unsecured and abandoned buildings. Contra Costa County Ordinance 720-4 provides the authority and direction to order the proper securing and boarding of dwellings and buildings during temporary periods of vacancy pursuant to a permit, and that dwellings and buildings do not remain vacant and unoccupied for appreciable periods of time. A vacant or abandoned building subject to code enforcement action is defined as a business or residential occupancy that has ceased and whose doors, windows or other openings are broken or missing, so as to allow uncontrolled access to the interior or exposure to the elements. Contact us at 925-655-2710 or Toll Free at 877-646-8314.
Keeping livestock is only permitted in specifically zoned land. Residential property typically only allows raising or keeping “ordinary household pets.” However because the county was once an agriculturally based community, many pieces of land within residential communities have retained legal non-conformance land use that permits the keeping of live stock. The planning department determines the permitted land use for each property within County jurisdiction. Check with the Application and Permit Center 925-655-2700 prior to keeping exotic or farm animals. Report exotic or farm animals in residential areas to Code Enforcement 925-655-7210.
Yes. The Building Inspection Division considers damaged or missing fencing used as pools barriers a serious and potentially life threatening situation. Pool fence barriers are proven to save lives and are required by law. They must be maintained in compliance at all times including periods of construction. If you encounter any unfenced pool contact Code Enforcement immediately.
Contra Costa County abatement procedures require the property owner be held responsible for any violations that exist on their property. All correspondence is directed to the property owner as well as known tenants. All fines or penalties are levied against the property and are recorded on the tax role. Tenant generated violations are difficult because the property owner often does not have immediate access to correct the problem. It is therefore strongly advised that a landlord closely and regularly monitor their properties for changes and violations.
Yes. Everyone is entitled to live in a safe and healthy building. It is strongly recommended that the landlord be notified immediately and given the opportunity to repair the problem prior to contacting Code Enforcement. In the event the landlord does not take action, reporting substandard building conditions to Code Enforcement will get the ball rolling to get these conditions corrected. Fear of repercussions is commonly heard for not reporting substandard conditions in rentals. Complainants anonymity are protected by law. Names and personal information will not be released. Contact us at 925-655-2710 or Toll Free at 877-646-8314.

No, the County Surveyor’s Office only performs surveys on County owned land, including County road and flood control channel rights-of-way.
Only a land surveyor or qualified pre-1982 civil engineer licensed in the state of California can provide property line location for a private survey in this state. Contact information for these professionals can be found in a telephone directory, by searching the Internet, or by contacting engineering and land surveying societies (see Resources, P. 21 of the Consumer Guide to Professional Engineers and Professional Land Surveyors or California Land Surveyors Association, Find a Surveyor). The California State Board website is another source of information for researching licensed engineers or land surveyors in your city or county where you can verify that the professional is currently and properly licensed and find out if there have been any complaints or disciplinary actions taken against the person’s license.
When interviewing land surveyors ask for local references on similar projects and compare qualifications and experience. Also, ask if they have previous experience working with your local planning department, public works department, municipal utility district, or County Surveyor’s Office. For your protection, the State Board insists that a formal contract is made between professional and client.
The County Surveyor’s Office has no authority to mediate private property issues.

Example:Market value of damaged or destroyed property = $220,000Market value of replacement property = $253,000Percentage above value of damaged or destroyed property = 15 percent Base year value of replacement = $220,000
If the market value of the replacement is more than 120 percent of the market value of the property substantially damaged or destroyed, the base year value of the replacement will be the factored base year value of the damaged or destroyed property plus the amount by which the value of the replacement exceeds 120 percent of the value of the property that was damaged or destroyed. Ref. California Revenue & Taxation Code 69(b) (2)
Example: Market value of damaged or destroyed property = $220,000Market value of replacement property = $275,000Percentage above value of damaged or destroyed property = 25 percent Base year value of replacement = $220,000 + (275,000 - (220,000 x 120%)) = $231,000

Unofficial transcripts are acceptable and but must list the student name, institution name, field of study, and date the degree was awarded. Copies of diplomas should indicate your name, the name of the school, a specific field of study, and date of graduation. If applicable, required documentation should be submitted with each application. Please do not send originals; copies of the required documents are acceptable. No submitted documents will be returned. For recent graduates who have not received proof of their degree yet, a letter from the registrar’s office stating that all requirements for graduation have been met and listing the field of study will be sufficient proof of graduation.
The applicant does not provide enough detail about their work experience and duties in the Work Experience section on their application. For example, if you are applying for Automotive Mechanic, just writing “10 years as mechanic at XYZ Ford” doesn’t provide enough detail about your duties. Writing “As a mechanic at XYZ Ford dealership, I performed computerized diagnostics, repaired and replaced all components of the drive train, specialized in repairing hybrid vehicles, and did trouble-shooting of difficult electrical problems.” provides enough information to assess your experience to see if it meets the Minimum Qualifications.
Required documents are not attached to the application, such as a transcript, diploma, or typing certificate. If the Job Announcement states you must attach documents to substantiate your education or certifications, your application will be rejected if you don’t.
The main priority of NPP is to eliminate health and safety deficiencies in the home. This typically includes, but is not limited to roof repair/replacement, water heater replacement, HVAC repair, and improvements to the plumbing and electrical systems.
The program provides applicants with loans up to $70,000 and grants up to $15,000. The type of funding that you are offered depends on factors such as your current household income, housing expenses, and equity in your home. Funding for the program comes directly from the U.S. Department of Housing and Urban Development’s Community Development Block Grant (CDBG), and Contra Costa County acts as a steward. Once approved, the money is actually paid directly to your chosen contractor at set intervals as work progresses and is verified as complete. Grants do not need to be paid back, while loans become due in either 15 or 30 years. At the time that the loan matures, some borrowers with deferred loans may be eligible for an extension or have their loan converted to amortizing, depending on their income.
NPP uses the “sealed bid” procurement method for major projects. Homeowners work with a home inspector to draft a scope-of-work and eligible contractors send in sealed bids based on their estimates for the work. The lowest, most responsible bidder is awarded the project.
Homeowners work with a home inspector to put together a scope-of-work that includes eligible work. However, deviations often occur to facilitate the winning proposal. If you were not awarded enough funding to accommodate all of the work you have requested, the home inspector will ultimately determine which work must take precedence, based on detriment to health and safety.
Yes, both of the loans offered through the program are secured through an encumbrance (lien) on your property’s title (similar to a second mortgage).
Contractors must have a B-class contractor’s license through the State Contractor’s License Board, meet insurance requirement (General Liability, Auto, and Worker’s Comp), and abide by program rules.
A “household” refers to all persons occupying a housing unit as their primary place of residence. Occupants may be a family, two or more families living together, a tenant, or any other group of related or unrelated persons who share living arrangements.
An “Owner-occupant” is a resident of a property who holds the title to that property. In order to qualify for the program, the property must be the primary place of residence for all owners.
No, there is no credit check, nor does credit play a role in our decision to fund an applicant. This program is designed for County residents who would otherwise be unable to secure a loan from a traditional bank.
In order to qualify for the program, any bankruptcy must be finalized/discharged from record. The court appointed trustee must no longer be involved in the decision-making process of homeowner transactions.
Please see the project map
The maximum height of a fence is six feet. The maximum height of a retaining wall is three feet. Maximum combination of a fence and retaining wall is six feet total but the wall may not exceed three feet. If these criteria are met, then the fence and retaining wall may be placed within the required setbacks. Generally, fences and retaining walls that meet these criteria do not require planning approval and permits are not needed.
The Tree Protection and Preservation Ordinance (Chapter 816-6) defines a protected tree. A tree is either protected or not protected based on its characteristics (e.g. trunk size, species) and the characteristics of the property on which it is located. The Ordinance requires that the property owner obtain a tree permit from the county before trenching, grading or filling within the dripline of any protected tree or before cutting down, destroying, trimming by topping or removal of any protected tree.
A Home Occupation is a business activity that is conducted at a residential dwelling by a person residing in the dwelling and is a secondary and incidental use of the dwelling as a residence.
No Home Occupation may be conducted at a residential dwelling unless a home occupation permit or a land use permit has been issued.
What type of structures and uses are allowed on individual properties depends on what zoning district the property is located in. If the site is located in the unincorporated area, planning staff can determine the zoning district upon request if you visit the Application & Permit Center or call 925-655-2700 Before visiting or calling, make sure you have the specific Assessor’s Parcel Number (APN), also referred to as the Property Tax Number, or address for the site.

The Probation Department is an arm of the court and an integral part of the criminal justice system. Children and adults are placed on probation by the court after a finding that they have committed a crime. In this scenario Probation would lack jurisdiction and be unable to provide direct services. However, Probation Officers routinely work with counselors, school officials and other professionals who do provide direct services to troubled families. Please call and ask to speak to the officer of the day if you would like to be referred to a local resource agency.
Contact your local law enforcement if you or anyone in your family has been the victim of a crime or is in fear of their safety.

The County Surveyor has no authority to mediate private property issues.
A stop sign is intended to determine the right of way at an intersection. It is a rather poor speed control device. Studies have shown that the effectiveness of a stop sign on speed ranges from 10 to 150 feet from the sign, after which a vehicle will regain its original speed or faster. If a speeding problem exists, the County can park a radar trailer on your street to inform drivers of their speed.
No. If your property is a lot in a subdivision we can provide a copy of the recorded subdivision map which will show easements created by that map and other easements affecting the property at that time; however, there is no reason to assume that other easements have not been created since.

Only a land surveyor or qualified pre-1982 civil engineer licensed in the state of California can provide property line location for a private survey in this state. Contact information for these professionals can be found in a telephone directory, by searching the Internet, or by contacting engineering and land surveying societies (see Resources, P. 22 of the Consumer Guide to Professional Engineers and Professional Land Surveyors or California Land Surveyors Association, Find a Surveyor). The California State Board website is another source of information for researching licensed engineers or land surveyors in your city or county where you can verify that the professional is currently and properly licensed and find out if there have been any complaints or disciplinary actions taken against the person’s license.

The Flood Control District has over 2,000 data points where the flow rates have been calculated. Most of these are the “design” flow rates based on General Plan build out2. Depending on the watershed size, the flow rate could be for the 10-year, 25-year, 50-year or 100-year flood. For information on the flow rates that the Flood Control District has for these data points call theCounty Public Works Department, Flood Control Division at (925) 313-2000 or email your request.
For tract numbers for the entire county, and parcel map numbers for the unincorporated areas of Contra Costa, contact the Department of Conservation and Development (DCD) (925) 674-7722. For parcel maps in other cities, obtain the number from the city.
The Flood Control District does not provide sand bags to private property owners. Often, in times of emergencies, the County may provide sandbags during significant storm events to residents in the unincorporated county.
There are, however, locations throughout the County where residents may go to fill their own sandbags. Please note that you will need to bring a shovel, but the bags and sand are available for free. For more information on this, please visit the County's webpage for sandbag locations.

Blocked crossings occur when stopped trains impede the flow of motor vehicle or pedestrian traffic at railroad tracks for extended periods of time. Blocked crossings pose potential safety risks, specifically in locations where trains routinely hinder roadway and pedestrian movement for extended periods. In these cases, frustrated drivers seeking to avoid extended delays may attempt to clear the crossing before a train arrives, and pedestrians may be tempted to crawl between stopped railcars. Further, blocked crossings can have detrimental effects on quality of life, making people late for work, school, and appointments and possibly contributing to roadway congestion. Currently, there are approximately 130,000 public highway/rail grade crossings in the United States.
If you are experiencing an blocked crossing for an extended period visit the Federal Railroad Administration website to report it.
Contact the County Assessor's Office at (925) 313-7500.

BMPs are devices or control measures for managing stormwater run-off. They include structural drainage inlet protection like catch basin inserts, gravel bags and straw waddles as well as operational controls like training, good housekeeping, adequate spill response and proper material handling and storage.
POCs are pollutants that impair waterways which are commonly found in urban run-off. They include Total Suspends Solids (TSS), sediment, bacteria (fecal coliform) and pathogens, heavy metals (e.g., lead, zinc), oil and grease, polyaromatic hydrocarbons (PAHs), synthetic organics (pesticides, PCBs), nutrients (fertilizers), oxygen demanding substances (vegetations, pet waste), and litter.
The Public Works is located at 255 Glacier Drive in Martinez. Office hours are Monday through Thursday from 7:00 a.m. to 5:00 p.m. and Friday from 7:00 a.m. to 4:00 p.m. (closed 12:00 p.m. to 1:00 p.m.). The main phone number is (925) 313-2000.
Property owners can help the County’s maintenance efforts by preventing private trees and shrubs from encroaching onto County roads. These encroachments are in violation of Division 1002 of the Title 10 County Ordinance Code. Please see this diagram for acceptable tree clearances (PDF). For information on power lines and trees, please see the PG&E website on this subject.
Property owners can help by removing the leaves that have fallen onto their property, and disposing of them in a proper manner. Clear the tops of grates and in front of culvert pipes. With every property owners’ help, we can prevent flooding and help the environment. Please see the Drainage Maintenance Brochure (PDF) for more information on how to prepare.

A cape seal is applied in a two-step process. The first step in the process involves application of a chip seal; the second step involves the application of a slurry seal. Cape seals are used on collector and residential roads that have a significant amount of wear. Schedule information regarding the contracted cape seal application can be obtained by calling the Public Works Department’s Construction Division at (925) 313-2320.
The County Public Works Department Maintenance crews perform two types of chip seal:
• A single chip seal involves spraying liquid asphalt on the pavement followed by the spreading of a layer of small aggregate (chips) that is embedded into the oil.
• A double-chip seal is a single chip seal with a second application (layer) of liquid asphalt and small aggregate.
Single and double-chip seals are typically used on arterial and collector roads that have a significant amount of wear and high traffic volume. Schedule information regarding the chip seal application can be obtained by calling the Public Works Department Maintenance Division at (925) 313-7000, or you can visit our Pavement Management Program page.
A micro-surface seal is a mixture of fine aggregate and liquid asphalt that is spread over the pavement by a County-hired contractor. Micro-surface seals are used on arterial, collector and residential roads that are in good condition. Schedule information regarding the contracted micro-surface seal application can be obtained by calling the Public Works Department’s Construction Division at (925) 313-2320.
A slurry seal is a mixture of fine aggregate, liquid asphalt and water that is spread over the pavement by a County hired contractor. Slurry seals are used on arterial, collector and residential roads that are in good condition. Schedule information regarding the contracted slurry seal application can be obtained by calling the Public Works Department’s Construction Division at (925) 313-2320.
A traffic Area of Benefit (AOB) is a development traffic mitigation fee program designed to improve the capacity and safety of the County’s road network within a defined boundary as development occurs. The AOB fee programs are supported by County ordinances which are adopted by the County Board of Supervisors. Money collected within a given AOB will be used to fund road improvement projects that mitigate traffic impacts generated by new development projects.
All of the land that drains to a common receiving body of water. In Contra Costa County we have 32 watersheds, several of these share boundaries with Alameda County. Watersheds are commonly named for the waterway or water body they flow to.
An illicit discharge is any non-stormwater discharge or discharge to the storm drain system that is not composed entirely of rain or precipitation run-off.
Call 911 or the Sheriff’s Dispatch (925) 646-2441 to report an illegal discharge going on right now. Call (925) 313-2236 to report an illicit discharge that has taken place in unincorporated County or call 1 (800) NO-DUMPING to report an illicit discharge that occurred in other cities/towns in Contra Costa County.
An NOI is a “Notice of Intent’ application to be included in one of CA’s General Stormwater Discharge Permits. If you are a commercial or industrial facility covered by certain NAIC code like chemical manufacturing or vehicle servicing, you may be required to file an NOI for inclusion in CA’s General Permit for Industrial Facilities. If you disturb soil of more than 1 acre you may be required to file an NOI for inclusion in CA’s General Construction permit. If you are a point source discharger like an industrial facility you may be required to apply for an individual NPDES permit. If you are a municipality that owns/maintains an MS4 you may be required to apply for a Municipal Stormwater Discharge NPDES permit.
C.3 refers to Provision C.3 of the County’s NPDES Permit, which was added to the Permit in 2003. This provision requires stormwater runoff from projects creating and/or redeveloping at least 10,000 square feet of impervious surface to treat stormwater runoff with permanent stormwater management facilities, and requires projects creating and/or redeveloping to design such facilities to control runoff rates and volumes (in addition to treatment). Projects that are not required to comply with C.3 still implement permanent stormwater controls to the maximum extent practicable.
Integrated Pest Management (IPM) is an ecological approach to dealing with pests using mechanical, physical, biological, and cultural methods first and chemicals generally as a last resort.
NPDES stands for the National Pollutant Discharge Elimination System. It’s a permitting program required under the U.S. Clean Water Act for discharges to surface waters of the U.S. In CA, USEPA has delegated its authority to implement the NPDES Program to CAL/EPA’s State Water Resources Control Board (SWRCB) who in turn manages the NPDES Program via five Regional Water Quality Control Boards (RWQCBs). In Contra Costa County, two RWCQBs oversee our County’s discharges to the Bay and the Delta, the San Francisco Bay and Central Valley RWCQBs, respectively.
The Adopt-A-Road Program encourages organizations, corporations, groups and individuals to participate by providing volunteers to maintain and enhance Contra Costa County roads. For more information, please refer to our Adopt-A-Road Program guide (PDF). If you have questions about the program, please call (925) 313-7000.
The Area of Benefit (AOB) Program is based on the following government codes:
The Department maintains online project information on capital improvement projects. If the project is not on the list, it may be part of a development project and/or is being done under an encroachment permit. Contact the Design/Construction Division at (925) 313-2320.
The CRIPP is a programming document that anticipates revenues and identifies maintenance, rehabilitation, safety, and capacity improvement projects to be funded with the identified revenues.
Contra Costa County has 31 major watersheds and sub-watersheds containing more than 1,300 miles of creeks and drainages. Of that total, the County maintains approximately 75 miles of improved creeks and drainages. The rest is the responsibility of private property owners.
The County maintains only those drainage facilities required as a condition of development constructed to standards applicable at the time of construction and located in an easement or other land right accepted by the County. Creek maintenance is the responsibility of the owner whose property abuts a creek.
When the creek area is not properly maintained, the resulting obstructions can lead to increased flooding, changes in the course of the creek, and increased erosion on the obstructed property and/or downstream properties. See Division 1010 of the Title 10 County Ordinance Code for more information on. The Public Works Department recommends the following guidelines on private creek maintenance (PDF).
The County Title 9 (Title 9: 911-2.010) set the design storm based on the watershed area draining to the creek of drainage facility as follows:
A Stormwater Pollution Prevention Plan (SWPPP) is a document that describes how a project will prevent pollution during the construction process. This document details how erosion will be prevented and how sediment will be controlled, as well as how other construction-related pollutants, such as concrete dust and fluids from construction equipment, will be prevented. SWPPPs, which are required under the California Construction General Permit, must be submitted for projects disturbing at least 1 acre of soil, and for certain projects involving less earthwork but pose special threats to water quality. Smaller projects also are required to implement adequate erosion and sediment controls.A Stormwater Control Plan (SWCP) is a document that details permanent stormwater management facilities (such as bioretention areas) that will be incorporated into development projects to treat stormwater runoff and control runoff rates and volumes after the construction process is completed. SWCPs are required for projects that must implement permanent stormwater management facilities to comply with C.3 of the NPDES Permit.
A point source, also termed ‘end of pipe’ discharge, is a discharge from a defined, discrete conveyance like an outfall coming off an industrial property. The US Clean Water Act was enacted to stop point source discharges like sewage and industrial chemicals to our waterways.Today, non-point source pollution is the primary contributor of pollutants to our waterways. It comes from a variety of diffuse sources like atmospheric deposition, automotive leaks, and brake pad dust, fertilizer and pesticide use, construction, agriculture, mining and fecal waste. Pollutants from these sources are picked up by urban run-off and deposited into our surface waters impairing their beneficial uses.Municipalities are required to educate residents and inspect business in stormwater pollution prevention practices.
Both the Contra Costa Clean Water Program and the County Watershed Program (CWP) are tasked with ensuring compliance with the Municipal Stormwater National Pollutant Discharge Elimination System (NPDES) Permit. The NPDES permit is issued to the Clean Water Program, which is a collaboration between the County (represented by the County Watershed Program), the 19 incorporated cities and towns in the County, and the County Flood Control and Water Conservation District (“Co-Permittees”).The Clean Water Program (http://www.cccleanwater.org) has its own staff that interacts with regulatory and elected officials, and provides guidance to the Co-Permittees. The Co-Permittees benefit from these collaborative efforts which the individual jurisdictions time and money. Ultimately, however, each jurisdiction is individually responsible for administering the NPDES permit within the bounds of its jurisdiction.Operationally, the County Watershed Program is a program within the Flood Control Division of the County’s Public Works Department. CWP is responsible for ensuring compliance with the NPDES permit in the unincorporated areas of the County.
Storm drain systems include the gutter, drainage inlets, catch basins, piping and the waterways they convey stormwater to in order to prevent flooding of our streets. Stormwater flows through these conveyances directly to receiving waterbodies such as the Delta and Bay without being treated. Storm drain systems are also often referred to as MS4s or Municipal Separate Storm Sewer Systems. Sanitary sewers transfer wastewater from our homes and businesses to wastewater treatment plants for primary, secondary or tertiary treatment prior to being discharged to receiving waterbodies via outfall pipes or reclaimed for irrigation purposes.

Current and future projects are listed in our Advertised & Upcoming Construction Projects webpage.
Illegal dumping is a serious problem in the County. Do not approach someone illegally dumping on public land or streets. Record the license plate number and vehicle information. When it is safe, contact local law enforcement and report it providing the license plate number and vehicle information (i.e., year, make, model, color, etc.). If the dumping occurs in the unincorporated county report it to the Contra Costa County Sheriff's Department. If the dumping occurs within incorporated city limits report it to the local Police Department. Dumping on private land should be reported to Code Enforcement at (925) 655-2710 for file a complaint online.
Fees are adjusted periodically to reflect changes in development potential and traffic needs. Fees are also subject to change annually based on changes in the applicable construction costs index.
AOB fees are collected through the Department of Conservation and Development, Building Inspection Division at the issuance of the building permit. Fees are collected at the rate in effect at the time the building permit is issued.
AOB fee credits are granted when the preexisting use is replaced by a new use that generates more traffic. The applicant would receive credit for traffic generated by the preexisting use. A project that changes a single family home into a commercial/retail building, or modifies a light industrial building into a commercial/retail building are examples of projects that would receive fee credit.
AOB fee waivers are granted only when vehicle trips are not added to the road network as a result of the proposed development (e.g. replacing an existing single family home, with a new single family home).
An encroachment permit is needed for any work within County Road or Flood Control Right of Way. Visit the Permit Portal for information about permits and permitting or email the Application and Permit Center.
The County's surface treatment work typically begins in the summer and ends in the fall. The schedule may vary depending on weather conditions and/or the need to recalibrate equipment.

Anyone who develops property and adds additional vehicle trips to the road network is subject to AOB fees. This includes, but is not limited to property owners, residential developers, commercial developers, and industrial developers.
What are some of the possible fee categories?
County ordinances require that proposed work in creeks in unincorporated areas be reviews and allowed only by a County Drainage Permit. The Contra Costa County Flood Control and Water Conservation District (FC District) boundaries cover all of Contra Costa County. Within FC District right of ways (where FC District faculties were built and are maintained) a FC District Encroachment Permit is required. Within it's right of way FC District can dictate construction standards and methods, hydraulic and hydrology calculation methods, and other standards such as freeboard standards. The County has adopted the FC District standards and so in the unincorporated areas the FC District standards are used. FEMA will require you to use the FCD flow rates in any FEMA study. Other State and Federal entities have authority to control work with in creeks and riparian areas. When you apply for a Drainage Permit or FC District Encroachment Permit, we ensure that the permits are obtained from those entities as well.
The oil helps the new asphalt layer bond to the existing pavement below it.
The normal construction day is between 7:00 am and 5:00 pm. Workers may be out earlier or later depending on what portion of the project they are working on.
The County maintains only those drainage facilities required as a condition of development constructed to standards applicable at the time of construction and located in an easement, or other land right, dedicated to and accepted by the County.
Driveway access will be maintained throughout construction, but property owners may be subject to some delays.
It is possible to experience delays, but provisions have been made to ensure the flow of traffic in each direction for the duration of the project to minimize disruptions.

If you do not pay the first installment of your annual tax bill at the Tax Collector’s Office by 5 p.m. on December 10 (if December 10 falls on a weekend or holiday, taxes are not delinquent until 5 p.m. the next business day), or payment is not U.S.P.S. postmarked by that time and date, then the taxes become delinquent and a 10% delinquent penalty is added to any unpaid balance.
If you fail to pay the second installment at the Tax Collector’s Office by 5 p.m. on April 10 (if April 10 falls on a weekend or holiday, taxes are not delinquent until 5 p.m. the next business day.), or payment is not U.S.P.S. postmarked by that time and date, it becomes delinquent and a 10% penalty plus an administrative charge of $20.00 is added to the unpaid balance.
If you fail to pay the installments of your supplemental tax bill by the applicable delinquency dates, the same penalties accrue as for delinquent annual taxes.
If you pay your second installment without having paid the first, your payment will be applied to the unpaid taxes and penalties on the first installment and will leave your second installment unpaid and possibly delinquent.
If you fail to pay either or both installments at the Tax Collector’s Office by 5 p.m. on June 30 (if June 30 falls on a weekend or holiday, taxes must be paid by 5 p.m. on the preceding business day), or payment is not U.S.P.S. postmarked by that time and date, then the property becomes tax-defaulted and additional penalties and costs accrue.
Once the property has become tax defaulted, a redemption fee of $15 and additional penalties begin to accrue at the rate of 1 1/2% per month of the unpaid taxes. This monthly penalty is added at 5 p.m. on the last day of each month (or the following business day if the last day of the month falls on a weekend or holiday).
Your taxes can remain unpaid for a maximum of five years following their tax default, after which time your property becomes subject to the power of sale. This means that your property will be sold at a public auction or acquired by a public agency if you do not pay the taxes before the date on which the property is offered for sale or acquisition.
The amount needed to redeem tax-defaulted property in full is the sum of the following:
To obtain an estimate of the amount required to redeem your property, you should contact the Tax Collector’s Office at (925) 608-9500. When making your request, you will need to provide the Parcel Number, which you can find on any previous tax bill, the Sale ID (SID) found on your Redemption Tax Notice, or the address of the property. Also, be sure to specify the date on which you wish to redeem so that the penalty can be calculated properly. One year’s delinquent taxes may not be redeemed separately from other years delinquent taxes. When the redemption amount is calculated, the total taxes owed for all delinquent years are combined together.
To obtain an estimate of the amount required to redeem your property, contact the County Tax Collector’s Office at (925) 608-9500. Please provide either the Assessor’s Parcel Number (APN), the property address, or the tax-defaulted Sale ID number. Be sure to specify the month in which you plan to pay off or redeem your property so the correct amount is calculated properly.
Your taxes can remain unpaid for a maximum of five years following their tax default, at which time your property becomes subject to the Tax Collector's power of sale. This means that after being given an official notice of the pending sale, your property will be sold at a public auction or acquired by a public agency if you do not pay the full amount of Redemption before the date on which the property is offered for sale or acquisition.
No, one year's defaulted taxes may not be redeemed separately from other years' defaulted taxes. When the Redemption amount is calculated, the total taxes owed for all defaulted years are combined together.
If you are unable to pay the full redemption amount (for example, unpaid taxes for all defaulted years plus penalties and charges), you may start an installment plan of Redemption. This plan allows you to make payments on your defaulted taxes over a five-year period beginning on the date you make the first payment of the installment plan.
NOTE: you must qualify for the installment plan within five years of the time the property first became tax-defaulted.
Any taxpayer may apply for Installment Plan for Redemption taxes as long the property in question has been in tax-default for less than five years.
To start an installment plan, you must:
If you start an installment plan between July 1 and the following April 10, the current year's taxes and any supplemental taxes must be paid by April 10 or the payment plan will default. To start an installment plan between April 11 and June 30, all outstanding current year's taxes (plus any penalties and charges) must first be paid in full.
No, currently there is no fee for applying.
You can start a payment plan after the date on which the property has become tax defaulted (June 30) and within five years of that date. On the fifth year, your property becomes subject to the power of sale and a payment plan is no longer an option. The Redemption amount must be paid in full as a single payment in order to redeem the property from the tax sale.
If you wish detailed information about a payment plan of redemption, contact the Tax Collector's Office at (925) 608-9500.
Under the installment plan you are required to make at least one payment each year for five years, in addition to paying each year's annual taxes. By April 10 of each year you must have paid a sum total of 20% or more of the plan, plus interest (which accrues at the rate of 1-1/2% per month on the unpaid balance once the plan). If you fail to pay the required amount of the plan or fail to pay your current Secured Property or Supplemental Property taxes, if applicable, on or before April 10 of each year, then your installment plan will default.
You can, however, pay the total unpaid balance plus accrued interest any time before the fifth and final payment is due.
Yes. Interest continues to accrue at a rate 1.5% per month (18% APR) on the unpaid balance.
If your installment plan defaults due to failure to make the plan paymentor current year tax payment before the end of the fiscal year, you maybegin another installment plan provided less than five (5) years haveelapsed since the original tax default date. However, your next installment payment plan may not be started until July 1 of the following fiscal year. You may NEVER start a payment plan in the fiscal year the property becomes subject to the power of sale.
To start the new plan, you must pay at least 20% of the Redemption amount plus any current year and/or supplemental taxes that are due. Any payment(s) made on the previous (defaulted) plan will be applied toward the initial payment, but any interest savings that were achieved will be forfeited.
When you begin an installment plan, you have five (5) years to pay the full redemption amount. It is to your advantage not to default on an annual installment plan, as there are additional penalties. When a second installment plan is started, the minimum payment amounts are recalculated as though there had been no previous annual payment plan.
No. Your installment payments NEVER include your current year's taxes, which must be paid separately.
The taxpayer is responsible for the property tax bills. However, unpaid real estate property taxes remain with the property.
Redistricting is the once-a-decade process of redrawing the political boundaries for elective offices after the U.S. Census.
Redistricting is the regular process of adjusting the lines of voting districts in response to accordance with population shifts within the County. Every ten years, supervisorial districts must be redrawn so that each district is substantially equal in population. This process is important in ensuring that each Supervisor represents about the same number of people. Redistricting is done using U.S. Census data, which is expected to be released by September 30, 2021.
In addition to being substantially equal in population, any supervisorial district boundaries must comply with voting rights laws. The California Voting Rights Act requires more than 500 jurisdictions in California to redistrict in 2021-2022.
In Contra Costa County, the Board of Supervisors is responsible for approving the final map of new supervisorial district boundaries. The effort will be supported by a multi-disciplinary team of staff from the County Administrator’s Office, Elections Office, Department of Conservation and Development, Department of Information and Technology, and other County departments. Ultimately, the Board of Supervisors will take final action on approval of a map that establishes the new supervisorial districts. The Board of Supervisors will hold public hearings and will receive public input. The process will include engagement with communities, including under-represented and non-English speaking communities, through the public hearings and public outreach process that is designed to develop supervisorial district maps that both meet legal requirements and reflect the County’s diversity.
Current Law requires that our redistricting process must be completed by December 15, 2021.
Redistricting determines which neighborhoods and communities are grouped together into a district for purposes of electing a member of the Board of Supervisors who represents that district. The County Board of Supervisors is seeking input in establishing the next district map for our supervisorial districts through a public process. You have an opportunity to share with the County Board of Supervisors how you think supervisorial district boundaries should be drawn to best represent your community.
To read more about the process or provide input, please visit Contra Costa Redistricting website at www.CoCoRedistricting.org.
View a timeline of the process on the Timeline and Events page.
You can contact the County Clerk of the Board at firstname.lastname@example.org find out more about how the process works.
You can see the existing districts on the 2011 Supervisorial District Map (PDF).
Use our interactive map to find what district you live in.
District lines must be drawn to ensure the five supervisorial districts are substantially equal in population. Under state law, population is determined based on the total population of residents of the County, as determined by the last Census. To the extent practicable, in accordance with the FAIRMAPS Act (AB 849), and as amended by AB 1276, district lines also must be adopted using the following criteria in the following order of priority:
Sign up to receive email notifications.
The County will notify the public about redistricting hearings and workshops, post district maps online before the maps are adopted, and create a dedicated webpage for all relevant information about the redistricting process. The County will conduct a robust public messaging program and implement a community outreach plan to guide the County’s outreach to local media outlets and members of the public, including under-represented and non-English speaking communities. The County will publicize the redistricting process via social media engagement, press releases, public notices posted at County facilities, advertisements on Contra Costa Television (CCTV) (channels Comcast Cable 27, ATT/U-Verse 99, and WAVE 32), advertisements and notices in newspapers, and information on the County’s dedicated redistricting website. We will work with community groups of all kinds to inform them about the redistricting process.
Live language translation and other accommodations can be provided at our public hearings and workshops if a request for translation or accommodation is submitted at least 72 hours in advance of a scheduled public hearing or workshop.
Request live language translation and accommodations.
All members of the public are encouraged to share their views about County supervisorial redistricting at any of the public hearings or workshops. There will be redistricting workshops held in each of the five supervisorial districts. The purpose of these meetings is for the County to receive broad public input on the redistricting process. View the Redistricting Timeline and Events page for hearing and workshop dates.
Learn more about public input opportunities for redistricting.
The County will be holding both public hearings and workshops to receive public input on how supervisorial district lines should be drawn. You can find the public hearing and workshop schedule on the Redistricting Timeline and Events page.
Members of the public may submit their own proposed redistricting plans or draft maps directly to the County. The input from the public will help the County develop its redistricting plans.
Learn more about submitting your map idea.
No, you can draw boundaries for any part of the County, or just the district where you’d like your neighborhood to be as part of a supervisorial district.

Once submitted, maps from members of the public are considered public records and will be posted on the website. Your personal information will not be shared on the website.
State law defines a “community of interest” as “a population that shares common social or economic, geographic, or cultural interests that should be included within a single supervisorial district for purposes of its effective and fair representation. Communities of interest do not include relationships with political parties, incumbents, or political candidates.”
One of the guidelines for drawing district boundaries is to learn about communities of interest across the County and to the extent practicable, to try to keep community of interest together in a district.

La restructuración distrital es un proceso que ocurre cada diez años para trazar de nuevo los límites políticos para los cargos de elección popular después del Censo de los EE. UU.
La restructuración distrital es el proceso periódico que consiste en ajustar las líneas de los distritos electorales en respuesta a los cambios poblacionales ocurridos en el Condado. Cada 10 años, los distritos deben trazarse nuevamente, de modo que cada distrito tenga básicamente la misma población. Este proceso es imortante para garantizar que cada Supervisor represente aproximadamente el mismo número de personas. La restructuración distrital se realiza usando los datos del Censo de EE. UU., cuya publicación se espera a más tardar el 30 de septiembre de 2021.
Además de tener básicamente la misma población, los límites de cualquier distrito de supervisión deben observar las leyes de derechos de voto. The California Voting Rights Act requires more than 500 jurisdictions in California to redistrict in 2021-2022.
En el Condado de Contra Costa, el Consejo de Supervisores es responsable de aprobar el mapa final de los nuevos límites de los distritos de supervisión. Esta labor estará respaldada por un equipo de personal multidisciplinario de la Oficina de Administración del Condado, la Oficina de Elecciones, el Departamento de Conservación y Desarrollo, el Departamento de Información y Tecnología y otros departamentos del Condado. En última instancia, el Consejo de Supervisores tomará la decisión final sobre la aprobación de un mapa que establezca los nuevos distritos de supervisión. El Consejo de Supervisores realizará audiencias públicas para recibir la opinión del público. El proceso incluirá la participación con comunidades, incluidas las comunidades que no tienen suficiente representación y las comunidades que no hablan inglés, mediante audiencias públicas y el proceso de difusión pública, que están diseñados para desarrollar mapas de distritos de supervisión que cumplan con los requisitos legales, al mismo tiempo que reflejen la diversidad del Condado.
La Ley actual requiere que el proceso de restructuración distrital se complete a más tardar el 15 de diciembre de 2021.
La restructuración distrital determina qué vecindarios y comunidades se agrupan en un distrito para fines de elegir un miembro del Consejo de Supervisores que represente a ese distrito. A través de un proceso público, el Consejo de Supervisores del Condado busca opiniones para establecer el siguiente mapa distrital para nuestros distritos de supervisión. Usted tiene la oportunidad de compartir con el Consejo de Supervisores del Condado su opinión sobre cómo deben trazarse los límites de los distritos de supervisión para lograr la mejor representación de su comunidad.

Las líneas distritales deben trazarse de modo que garanticen que los cinco distritos de supervisión sean básicamente iguales en cuanto a población. De acuerdo con la ley estatal, la población se determina con base en la población total de residents del Condado, según la determine el Censo más reciente. En la medida en que resulte posible, de acuerdo con la Ley FAIRMAPS (Ley de Mapas Justos) [Proyecto de Ley 849], según se ha modificado por el Proyecto de Ley 1276, las líneas distritales también deben adoptarse usando los siguientes criterios, en el siguiente orden de prioridad:
Además, los límites no pueden trazarse para fines de favorecer o discriminar a ningún partido político.

La ley estatal define "comunidad de interés" como "una población que comparte intereses sociales, económicos, geográficos o culturales que debe incluirse en un solo distrito de supervisión para fines de su representación justa y eficaz. Las comunidades de interés no incluyen relaciones con partidos políticos, políticos en funciones ni candidatos políticos".
Uno de los lineamientos para trazar los límites distritales es conocer a las comunidades de interés de todo el Condado y, en la medida que resulte posible, tratar que las comunidades de interés permanezcan juntas en un distrito.

As a new owner, you are responsible for any taxes that were not paid as of the time escrow closed. Even though taxes are prorated between the buyer and seller during escrow and proper credit is given to each, the actual taxes may not have been paid to the Tax Collector by that time. You should read your escrow papers and/or title report to determine if any portion of the annual taxes were paid by the previous owner before the close of escrow.
Annual tax bills, which can be paid in two installments, are mailed once a year by the first of November. Since the bill contains payment stubs for both installments, this is the only bill regularly mailed each year by the Tax Collector. Depending on when the ownership change is placed on the tax roll, the annual tax bill could be sent either to the previous owner or directly to you. If there are any remaining unpaid taxes, and if you did not receive an annual tax bill from either the previous owner or the Tax Collector, you should contact the Tax Collector immediately and request one. It is your responsibility to obtain the bill. State law stipulates that failure to receive a bill does not permit the Tax Collector to excuse penalties on late payments.
In addition to annual taxes, you will probably be responsible for paying Supplemental Property Taxes. Any time property is sold or improved, the value of the property is reassessed. If the property has been reassessed at a higher value, you will receive one or more supplemental tax bills in addition to the annual bill mentioned above. (For more information on supplemental tax bills, please read our section on Supplemental Property Taxes.) If the property has been reassessed at a lower value, you will receive a refund.
The Secured tax bill is for taxes on the ad valorem (value based) of the real estate property being assessed and for special assessments charged against the property.
Through the Assessor’s Office you can apply for the homeowner’s property tax exemption, veteran’s exemption, or church and welfare exemption. These programs allow for assessment exemptions that result in tax savings. For further information, contact the Assessor’s Office at (925) 313-7400.
You may discuss the value with the Assessor if you feel a change is in order and request a review of your current assessed value versus the current market value (based on comparable sales). This process is commonly referred to as a Proposition 8 review.
Yes. You may take the matter up with the Assessor to see if that office will change the valuation. Additionally, the Board of Supervisors has established an Assessment Appeals Board for the purpose of resolving valuation problems in connection with Secured tax bills.
Applications for appeal must be filed within sixty days of the mailing date shown on the assessment notice. If you choose to appeal your assessment, you should still pay your tax installments in full by the appropriate deadlines; otherwise, you may incur penalties while the case is in appeals. If your appeal is granted, a refund will be issued to you.
Further information about the appeals process can be obtained by calling (925) 335-1901 or writing to: Clerk of the Assessment Appeals Board, 1st Floor, Suite 150, 1025 Escobar Street, Martinez, CA 94553

A new property owner’s regular secured tax bill is sent to the previous owner because the Tax Collector’s Office is unaware the property has been sold. Regardless of the reason, if you do not receive a secured property tax bill by November 10th, contact this office at (925) 608-9500 or go on to our website to Pay Online to enter your Assessor’s Parcel Number (APN) and view a pdf copy of the tax bill..
Current secured tax bill:
Paying on time will avoid penalties!
If your bill says you have prior taxes owing, you should contact the Tax Collector’s Office at (925) 608-9500 to get the current amount due. Please note that these taxes are not included in the total amount due on the bill and additional penalty on them accrues monthly at a rate of 18% per annum.
The State Controller’s Office (SCO) administers the Property Tax Postponement (PTP) Program, which allows eligible homeowners to postpone payment of current year property taxes on their primary residence. A postponement of property taxes is a deferment of current year property taxes that must eventually be repaid. Repayment is secured by a lien against the real property or a security agreement with the Department of Housing and Community Development for manufactured homes. Funding is limited and distributed on a first come, first served basis. Due to funding limitations, all who qualify may not be approved.
NO. Our office does NOT accept partial payments for current tax bills. Any payment less than the amount due at the time of receipt will be returned to the payer.
Please be aware that a 10% late-payment penalty will be assessed on the unpaid balance on the first installment. The penalty will also attach to the unpaid portion of the second installment plus a $20 cost.
Do you have an impound account with your lender? If so, you should receive a tax bill in your name with the word "INFORMATION COPY" appearing on the top right-hand corner of the front of the form.
If not, call your lender immediately to find out! If you have refinanced your house since the original billing and either your new lender or you is responsible for paying the bill, you must notify our office immediately of the change and request another bill be sent. The bill must still be paid in full by the due date regardless of the circumstance.
Special assessments are a charge on a tax bill for a service or benefit provided directly to a property. They are collected at the same time and in the same manner property taxes are collected.
Examples of these types of assessments are garbage collection, sewer, lights and landscaping maintenance, mosquito abatement, fire protection, water, sanitation and other such services.
A special district is formed in order to provide property specific services or benefits. These districts are permitted to charge an assessment for the services rendered under the applicable state law that allowed their creation. In accordance with state law, each fiscal year the special district provides the county Auditor-Controller with a listing of the parcels and the amounts to be charged to each parcel on the property tax roll. The district also provides the Auditor-Controller with a resolution authorizing the placement of the charge on specific parcels. Provided the legal requirements are met by special district, the county Auditor must place the special assessment charge on a property tax bill.
State law requires the immediate reassessment of property (for tax purposes) whenever a change of ownership or completion of construction occurs. If applicable, you will receive a supplemental tax bill reflecting the change in value for the balance of the tax year. Due dates for a supplemental tax bill depends on when the bill is mailed.
A decrease in value will result in a negative supplemental tax bill being issued. These negative bills or refunds do not cause a change to your current annual tax bill which must be paid timely to avoid penalty.
Supplemental tax bills do not replace the regular tax bill. Supplemental tax bills are not mailed to your mortgage company. They are not paid by funds in your impound account. If you receive a supplemental tax bill and have any questions about payment responsibility, please contact your mortgage company.
Yes, but not until the delinquent or "defaulted" taxes have been transferred to the Redemption roll, which occurs approximately mid-July following the fiscal year in which the taxes were due.
An Installment Plan of Redemption allows a taxpayer the ability to pay Redemption taxes in multiple installments. It is strongly recommended that prior to applying for the Installment Plan of Redemption, you contact your lender/mortgage company to ensure they allow a Tax Collector’s payment plan to pay the defaulted taxes. Please be aware that an Installment Plan of Redemption cannot be started (or restarted) after the property becomes Subject To Power To Sell. This occurs when the property has been on Redemption roll for more than five years.
To maintain the installment plan in good standing, you must:
Failure to make the required minimum payment and/or to pay the annual Secured taxes or any supplemental taxes that are due on or before April 10 of each year will result in a termination of the Installment Plan. Another Plan may be started only after the beginning of the next fiscal year as long as the property has not been in tax-default for more than five years.
NOTE: You may pay the total unpaid balance plus accrued interest any time before final payment is due. If you wish detailed information about an installment plan of redemption taxes, contact the Tax Collector’s Office at (925) 957-5280.
If the installment plan defaults, a new plan may not be started until July 1 of the following fiscal year. Additional penalties at an annual rate of 18% will continue to be computed on the unpaid balance each time a plan is restarted. Please be aware that an Installment Plan of Redemption cannot be started after the property becomes Subject To Power To Sell. This occurs when the property has been delinquent for more than five years.
Example: If you have delinquent taxes from the 1997-98 tax year, as of July 1, 2003, you CANNOT participate in the installment plan. You must pay in full the amount of outstanding taxes to keep the property from being sold at the Public Auction that is scheduled for early 2004.
Five years after the first year of nonpayment, your property becomes Subject to Power to Sell and may be offered at the next scheduled annual public auction.
Don’t panic! Prior to the end of the fifth year of default, we have options available for you to bring your taxes current. Give us a call at (925) 608-9500 or e-mail us at firstname.lastname@example.org
We accept requests by mail, walk-in, fax, and e-mail. Records staff will contact you by telephone, e-mail, fax or United States mail to advise you of the fees for this service. Requests will not be mailed unless all fees have been paid in advance. Your request for information is normally processed and mailed within 10 business days.
Under the existing law, the State Water Resources Control Board (State Water Board) and the California Regional Water Quality Control Boards (Regional Boards) prescribe waste discharge requirements for the discharge of stormwater by municipalities and industries in accordance with the National Pollutant Discharge Elimination System (NPDES) permit program and the Porter-Cologne Water Quality Control Act. The existing law requires regulated municipalities and industries to obtain a stormwater permit.
SB 205 would require a person or entity who conducts a business operation that is a regulated industry to demonstrate enrollment with the NPDES permit program by providing specified information, under penalty of perjury, on their application when applying to a city or a county for an initial business license or business license renewal.
To address the health and safety of drinking water sources statewide, the regulated industry is required to provide proof of enrollment with the NPDES permit program.
SB 205 was signed into law by Governor Gavin Newsom on October 2, 2019. It takes effect January 1, 2020.
Search Bill Number: "SB 205"
SB 205 requires specific types of businesses to demonstrate they have a stormwater permit when applying for an initial business license or when renewing its business license with the city or county of jurisdiction.
No. Only those businesses with primary Standard Industrial Classification (SIC) codes that are identified in or are applicable to the General Permit for Storm Water Discharges Associated with Industrial Activities (Excluding Construction Activities), also known as Stormwater Industrial General Permit.
Establishments with one or more primary SIC codes that are regulated require stormwater permit coverage. See also Questions 2 and 3 above.
SB 205 only applies to cities and counties that issue business licenses.
Contact the State Water Board or local Regional Board to inquire about stormwater permit requirements or regulations, as you may still be required to enroll in the Stormwater Industrial General Permit based on your SIC code(s).

The supplemental bill is for taxes on the increase in assessed value, prorated from the date of change in ownership or date of completion of construction to the end of the Fiscal Year. It is in addition to the original secured tax bill for your property. It does not replace the original bill. This bill is sent directly to the homeowner and NOT to the mortgage company.
On July 1, 1983, California State law was changed to require the reassessment of property as of the first day of the month following an ownership change or the completion of new construction. What is meant by new construction is any substantial addition to real property (e.g., adding a new room, pool, or garage) or any substantial alteration which restores a building, room, or other improvement to the equivalent of new (e.g., completely renovating an outdated kitchen). In most cases, this reassessment results in one or more supplemental tax bills being sent to the property owner in addition to the annual property tax bill.
Most changes in ownership caused by the sale of property result in reassessment. However, interspousal transfers, the transfer, sale, or inheritance of property between parents and their children, and the addition of joint tenants do not result in the reappraisal of property values.
Furthermore, homeowners over the age of 55 years who sell their principal residence and purchase a replacement dwelling within two years that is of equal or lesser market value and is located in the same county are eligible to transfer the pre-sale assessed value of their original property to the replacement dwelling. For further information, please contact the Assessor’s Office at (925) 313- 7400.
The Assessor first determines the new value of the property based on current market values. The Assessor then calculates the difference between the new value (set at the time of purchase or completion of new construction) and the old value (set on January 1 of the previous fiscal year). The result is the supplemental assessment value. Once the new assessed value of your property is determined, the Assessor will send you a notification of the amount to be assessed.
This reassessment usually results in an increase in property value, in which case your supplemental taxes will be calculated by the Auditor-Controller based on the change in value, and one or more supplemental tax bills will be created and mailed to you by the Tax Collector. However, in some instances the reassessment results in a reduction in value, in which case a refund will be prepared by the Auditor-Controller and mailed to you. A reduction in value will not reduce the amount due on the annual secured tax bill. The annual tax bill must be paid in the amount originally billed.
The supplemental tax bill is usually sent directly to you. If you purchase and then sell property within a short period of time, the supplemental tax bill you receive should cover only those months during which you owned the property, and the new owner should receive a separate supplemental tax bill. However, because of the large number of parcels and frequency of property changing hands, there are often delays in placing new assessments on the roll. Be sure to check the dates used to prorate the bill to ensure that the period covered is the period during which you actually owned the property. If you think there’s an error in the pro-ration of your supplemental tax bill, please contact the AuditorController’s Office at (925) 646-2236.
Yes. You may take the matter up with the Assessor to see if that office will change the valuation. Additionally, the Board of Supervisors has established an Assessment Appeals Board for the purpose of resolving valuation problems in connection with supplemental tax bills.
Yes. The supplemental tax bill is sent in addition to the annual tax bill and both must be paid as specified on the bill. For information on the annual tax bill, see our section on Secured Property Taxes.
No. Unlike the annual tax bill, lending agencies do not receive a copy of the supplemental tax bill. When you receive a supplemental tax bill, you must contact your lender to determine who will pay the bill. Generally, your impound account will only cover your annual tax bill and not your supplemental bill.
The supplemental tax bill provides the following information:
The bill may be paid in two installments and provides payment stubs for each installment, which show the amount due and the date that the amount must be paid to avoid penalties for late payment.
If you purchase and then sell property within a short period of time, the supplemental tax bill you receive should cover only those months during which you owned the property, and the new owner should receive a separate supplemental tax bill.
Because of the large number of parcels and frequency of property changing hands in Contra Costa County, there are often delays in placing new assessments on the roll. Be sure to check the dates used to prorate the bill to ensure that the period covered is the period during which you actually owned the property. If you receive an incorrect tax bill, contact the Auditor – Controller’s Office at (925) 646-2236.
No. You are only taxed on the supplemental value for the portion of the current Fiscal Year remaining after you purchased the property or completed new construction.
NOTE: If you purchased the property or completed new construction between January 1 and May 31, you will receive an additional supplemental bill for the entire following fiscal year.
Yes. It is possible to receive several supplemental tax bills, depending on when the ownership change or completion of new construction occurred and when the Assessor recorded the new value on the tax roll. Because property is assessed each January 1 for the upcoming Fiscal Year (the period July 1 - June 30), you will receive one supplemental bill if the change in property value due to ownership change or new construction is recorded on the tax roll between June 1 and December 31; you will receive two supplemental bills if the change in property value is recorded on the tax roll between January 1 and May 31.
The date on which supplemental bills become delinquent varies depending upon when they are mailed by the Tax Collector. If the bill is mailed between July 1 and October 30, the taxes become delinquent at 5 pm on December 10 for the first installment and 5 pm on April 10 for the second installment (the same delinquency schedule as for annual tax bills mailed in November).
If the bill is mailed between November 1 and June 30, the delinquency dates -- which are printed on the bill -- are determined as follows: The first installment is delinquent at 5 pm on the last day of the month following the month the bill was mailed; the second installment is delinquent at 5 pm on the last day of the fourth month after the first installment delinquency date.
Penalties of 10% are added to any installment that is not paid on time, and an additional $20 charge is added to a late second installment.
Yes. Delinquent supplemental taxes can be paid on an installment plan in the same manner as your annual property taxes once the taxes become delinquent. More information can be found in our section on delinquent property taxes.
You may very well be eligible for a homeowner’s exemption on your supplemental tax bill. Exemptions, however, are not granted automatically. You must apply to the Assessor before 30 days following the date of the notice from the Assessor of your supplemental assessment. As long as the home you purchased did not receive the homeowner’s exemption on the current year’s assessment, and as long as you occupy the home as your principal residence within 90 days of the purchase date, you would be allowed the full amount ($7,000) on the supplemental assessment. If your newly purchased home did receive the full homeowner’s exemption, however, you would not be able to receive the exemption on your supplemental assessment.
On May 29, 2003 you purchase a home on which no homeowner’s exemption had been allowed. Because you are reassessed on the first day of the month following an ownership change, in the current Fiscal Year you will pay supplemental taxes for the one remaining month. Your 2002-03 supplemental assessment amounts to $20,000. If you file for and qualify for a homeowner’s exemption, the entire $7,000 exemption amount would be deducted from the supplemental assessment BEFORE the taxes are calculated.
Yes. Supplemental taxes are eligible for the same property tax exemptions and assistance programs as your annual taxes. In addition to the homeowner’s exemption, you can apply through the Assessor’s Office for a number of other assessment exemptions (e.g., veteran’s, church, and welfare) that result in savings. You must, however, file for all exemptions before 30 days following the date of the notice from the Assessor of your supplemental assessment. For further information, contact the Assessor’s Office at (925) 313-7481.

It is an ad-valorem (value based) property tax that is the liability of the person or entity assessed for the tax. Because the tax is not secured by real property (such as land) the tax is called "UNSECURED."
All property that is not real property is considered personal property and therefore is issued an Unsecured tax bill. Some typical items assessed and collected on the unsecured roll are:
The lien for unsecured taxes is against the assessee and not against the property. The assessee can be any person owning, claiming, possessing, or controlling the property on the lien date.
The Assessor establishes the value of the unsecured property on January 1. This date is often referred to as the Tax Lien date. Ownership on the lien date, determines the obligation to pay taxes: Disposal, removal, or sale of the object of the assessment after the lien date will not affect the tax bill nor relieve the assessee of liability. No proration is made by the Tax Collector on unsecured taxes. Any proration is strictly a private matter between buyer and seller.
The tax bill will be issued to the owner as of the lien date January 1. Disposal, removal, or sale of the assets after the lien date will not affect the tax bill. No prorations are made by the tax collector on unsecured property taxes. Any pro-ration is strictly a private matter between buyer and seller. The owner of record as of January 1 is responsible for payment and will be lien if bill is not paid.
You should also contact the Assessor’s Office to make sure the ownership of record has been updated. Failure to do so could result in future billings and liens.
The January 1 value is multiplied by the tax rate (usually 1% plus voter approved indebtedness). The unsecured tax rate is the prior year secured rate.
An unsecured tax bill covers a fiscal year. The fiscal year begins July 1 and ends on June 30 of the following calendar year.
A fiscal year is the County’s accounting cycle. It is from July 1 each year through June 30 the following year.
Example: 1999-00 fiscal year is July 1, 1999 to June 30, 2000.
The County Assessor determines the person or entity to be assessed and the value of the property being assessed. The Auditor places a record on the roll for the Tax Collector to collect. The Tax Collector mails the tax bill to the latest billable address the Assessor has on file from the assesee.
Most unsecured bills are mailed July 31. These bills must be paid on or before 5 p.m. on August 31. If the bill is mailed after July 31, the delinquent date is extended to the end of the month following the bill’s issuance. In other words, if your bill is mailed in September, the delinquent date would be October 31.
If you do not receive a tax bill by July 10, contact the Treasurer - Collector's Office at (925) 608-9500.
Most unsecured bills are mailed before July 31st. These bills must be paid on or before August 31st. If the due date falls on a Saturday, Sunday or a legal holiday, the deadline is extended until the next business day.
If the bill is mailed after July 31st, the delinquent date is extended to the end of the month following the bill’s issuance. For example, if your bill were mailed in September, the delinquent date would be October 31st. If your payment is not received or postmarked by the delinquent date, a 10% penalty and a $30.00 collection fee are added to your bill.
If your bill remains unpaid for two additional months, a monthly penalty of 1.5% begins to accrue (an 18% per annum rate). In addition, if a Certificate of Tax Lien is recorded, an additional fee of $20.00 will be required to release the lien.
Generally, an annual unsecured tax bill is mailed out by June 30th each year. If you do not receive a tax bill by July 10th, contact the Treasurer-Tax Collector’s office immediately. Call (925) 608-9500.
FAILURE TO RECEIVE A TAX BILL DOES NOT RELIEVE THE RESPONSIBILITY FOR PAYMENT, NOR CONSTITUTES CAUSE FOR CANCELLATION OF PENALTY IF THE TAX BECOMES DELINQUENT.
NOTE: The penalty of 10% shown on the stub of your bill is not applied until the delinquency date. Do not include the penalty if payment is made on or before that date.
A tax penalty of 10% plus a $30 administrative fee will be charged on the date of the delinquency. Additional penalties at the rate of 1.5 % per month will be charged starting the 1st day of the second month after the delinquency date until the tax is paid in full.
Upon delinquency the following collection methods may be used to collect the tax:
Send payment to the address shown on the front of your coupon. If you do not have a tax coupon, then mail payment to:
Yes. U.S.P.S. postmark dates are honored as if the payment were received in the office as of the date of the postmark.
No. California law requires the Tax Collector to accept the US postmark, not a private meter date, as the date of payment.
Yes. For a 3rd-party processing fee you can pay with your credit or debit card Unsecured property taxes either in person at our Cashier counter or on our website at www.cctax.us. You can also make an electronic check payment online at no service charge.
Yes. Disposal of the property after the January 1 lien date does not eliminate your tax liability. If you sell the property before the unsecured tax bill is issued, make sure you collect an estimated amount for the unsecured tax from the buyer.
