FY 2015-2016 Annual Report C.2 – Municipal Operations
Permittee Name: Contra Costa County
FY 15-16 AR Form 2-1 9/30/16
Section 2 - Provision C.2 Reporting Municipal Operations
Program Highlights and Evaluation Highlight/summarize activities for reporting year:
Summary:
Contra Costa County (CCC) participated in the Contra Costa Clean Water Program’s Municipal Operations Committee. Refer to the C.2
Municipal Operations section of the CCCWP’s PY 2015-16 Annual Report for a description of activities implemented at the countywide and/or
regional level.
County Watershed Program (CWP) staff coordinate with County Public Works Department (PWD) Maintenance Division management and crews
throughout the year to ensure the implementation of stormwater best management practices during municipal maintenance activities.
This PY 2015-16 CCC’s municipal operations recovered 2,810 cubic yards of debris from street sweeping nearly 7,000 curbed miles. Our contractor
continues to provide monthly street sweeping for curbed streets in unincorporated Contra Costa County and provides additional bi-monthly street
sweeping to commercial areas in high trash generating areas.
Road crews recovered 1,595 cubic yards of illegally dumped large debris dumped on County road right-of-way; removed 143 cubic yards of
sediment, vegetation and debris and 368 cubic yards of silt during roadside ditch cleaning; removed 163 cubic yards of debris from cleaning out
1,804 catch basins and collected 58 cubic yards of debris and 2.4 cubic yards of silt from inspecting and cleaning an additional 10,083 catch
basins.
C.2.a. ►Street and Road Repair and Maintenance
Place a Y in the boxes next to activities where applicable BMPs were implemented. If not applicable, type NA in the box and provide an
explanation in the comments section below. Place an N in the boxes next to activities where applicable BMPs were not implemented for one or
more of these activities during the reporting fiscal year, then in the comments section below provide an explanation of when BMPs were not
implemented and the corrective actions taken.
Y Control of debris and waste materials during road and parking lot installation, repaving or repair maintenance activities from polluting
stormwater
Y Control of concrete slurry and wastewater, asphalt, pavement cutting, and other street and road maintenance materials and wastewater
from discharging to storm drains from work sites.
Y Sweeping and/or vacuuming and other dry methods to remove debris, concrete, or sediment residues from work sites upon completion of
work.
Comments:
Prior to each season’s municipal activities (e.g. catch basin cleaning, storm patrol, surface treatment, pavement maintenance, slide repair etc.)
CCC Maintenance crews are trained in each task’s Activity Description/Standard Operating Procedures. These trainings include written
descriptions of the work to be performed, planning criteria, work method, and check points. Throughout each tasks’ Activity Descriptions there are
FY 2015-2016 Annual Report C.2 – Municipal Operations
Permittee Name: Contra Costa County
FY 15-16 AR Form 2-2 9/30/16
numerous references to stormwater pollution prevention practices.
Crews grind and saw cut when necessary. When saw cutting is performed, crews use wet-vacuum systems to recover and properly dispose of all
slurry. The Activity Description for this task specifically addresses this issue: “If saw cutting is performed, ensure that all BMPs are followed e.g.
vacuum all slurry cuttings and loose material and protect drainage inlets.” As an additional storm drain system protection measure, all trucks in the
PWD Maintenance fleet contain spill kits in case of accidental releases, and crews are annually trained in their use.

Comments:
Contra Costa County (CCC) Maintenance crews use all appropriate BMPs for road and bridge repair/maintenance work to protect the MS4
system. Crews follow Caltrans Storm Water Quality Handbook Maintenance Guide, May 2003. Graffiti and tagging are removed by painting or
wiping with aerosol cleansers. Contracts for major County projects have BMP requirements that contractors must adhere to.
CCC bridge crews utilize drop cloths, silt fencing, straw wattles and filter fabric on storm drains where appropriate. Job sites are always left clean
after work is completed. Graffiti abatement is generally performed by spraying over graffiti with primer paint or wiping off localized tagging, such
as on street signs, with aerosol paint remover and a rag. All waste generated from these activities is taken to the County Central Waterbird Way
Corporation Yard’s hazardous waste storage area and properly disposed of by a hazardous waste management contractor.
On April 7, 2016 Public Works Department (PWD) Maintenance staff attended the Stormwater and Hazardous Substances Awareness and First
Responder Operations Annual Refresher training by the County Watershed Program and a Health Service Department Hazardous Material
Programs Certified Trainer. The training included segments on the Corp Yard’s Stormwater Pollution Prevention Plans (SWPPPs), non-storm water
discharges and appropriate best management practices, Emergency Contingency Plan, Hazardous Substances Awareness, Spill Clean-up
Procedures, and basic Hazardous Waste Management and Hazardous Materials Emergency Response. Staff in attendance included 56 crew
staff, 86% of Maintenance staff.
Some bridge and structural maintenance activities are conducted in-house by CCC Maintenance crews whose Standard Operational
Procedures require collection and proper disposal of all wastes, including spoils, in accordance with the Caltrans Storm Water Quality Handbook
Maintenance Staff Guide, May 2003. The PWD Design/Construction Division is responsible for putting together plans and contract specifications
for more specialized activities such as bridge deck methacrylate treatments and structural repairs. These projects are then bid out for construction
by contractors. CCC’s contractors adhere to the project’s contract specifications and Caltrans Standard Specifications, which include language

and oversight mandating the proper collection and disposal of all wastes. Construction resident engineers inspect projects and ensure stormwater
BMPs are followed.
C.2.e. ►Rural Public Works Construction and Maintenance
Does your municipality own/maintain rural1 roads: X Yes No
If your answer is No then skip to C.2.f.
Place a Y in the boxes next to activities where applicable BMPs were implemented. If not applicable, type NA in the box and provide an
explanation in the comments section below. Place an N in the boxes next to activities where applicable BMPs were not implemented for one or
more of these activities during the reporting fiscal year, then in the comments section below provide an explanation of when BMPs were not
implemented and the corrective actions taken.
Y Control of road-related erosion and sediment transport from road design, construction, maintenance, and repairs in rural areas
Y Identification and prioritization of rural road maintenance based on soil erosion potential, slope steepness, and stream habitat resources
Y No impact to creek functions including migratory fish passage during construction of roads and culverts
Y Inspection of rural roads for structural integrity and prevention of impact on water quality
Y Maintenance of rural roads adjacent to streams and riparian habitat to reduce erosion, replace damaging shotgun culverts and excessive
erosion
Y Re-grading of unpaved rural roads to slope outward where consistent with road engineering safety standards, and installation of water bars
as appropriate
Y Inclusion of measures to reduce erosion, provide fish passage, and maintain natural stream geomorphology when replacing culverts or
design of new culverts or bridge crossings
Comments including listing increased maintenance in priority areas:
PWD Maintenance Division prioritizes maintenance projects according to several criteria for pavement and drainage maintenance, and annual
catch basin/culvert inspection and cleaning. Road projects implement standard BMPs to minimize erosion and sediment transport related to road
construction and maintenance. In addition to assessing structural integrity, road crew inspections assess roads’ impacts to water quality. Water
quality impacts are a basis for scheduling and prioritizing maintenance projects. Road design standards are intended to minimize impacts to
water quality. In order to minimize erosion and impacts to fish passage and stream geomorphology, replacement of culverts and bridge crossing is
only carried out in dry weather and with all required environmental permits in place.
1Rural means any watershed or portion thereof that is developed with large lot home-sites, such as one acre or larger, or with primarily agricultural, grazing or open
space uses.

County Maintenance crews follow the creek protective BMPs outlined in the Routine Maintenance Agreement (RMA) with the California
Department of Fish and Wildlife for road maintenance activities located adjacent to waterways, including bank stabilization and roadway
shoulder repairs. The RMA requires specific environmental management activities, including preparation of semi-annual notification reports; limits
on heavy equipment usage; measures to protect fish and wildlife resources; and BMPs to minimize disruptions to habitat. If work is near a creek or
waterway a copy of the current Fish & Game RMA is required to be onsite at all times.

FY 2015-2016 Annual Report C.3 – New Development and Redevelopment
Permittee Name: Contra Costa County
FY 15-16 AR Form 3-1 9/30/16
Section 3 - Provision C.3 Reporting New Development and Redevelopment
C.3.a. ►New Development and Redevelopment Performance
Standard Implementation Summary Report
(For FY 15-16 Annual Report only) Provide a brief summary of the methods of implementation of Provisions C.3.a.i.(1)-(8).
Summary:
(1) County’s legal authority to implement C.3; Contra Costa County’s jurisdiction includes all unincorporated lands throughout the county,
including 17 unincorporated communities. Its legal authority to implement c.3 is equivalent to other municipalities within Contra Costa County
and is recognized as such by the County’s Clean Water Program.
(2) County’s development review and permitting procedures: Applicant submits development application to the County’s Department of
Development and Conservation (DCD). DCD planners are trained to identify projects that may be subject to c.3 requirements and includes them
in the Conditions of Approval for the project’s land use permit: it refers such projects to the Public Works Department’s Engineering Services
Division, which is charged with review and approval of the c.3 regulated project’s Storm Water Control Plan (SWCP), O&M Plan, and O&M
Agreement (which serves to codify the responsibility of the owner toward the project’s O&M Plan.). It also provides a guarantee that the owner
will maintain the project’s SW Treatment Facilities (SWTF) in perpetuity, as SWTF areas are annexed into a special communities facilities district
(CFD) that was created in 2007 to permit the County to inspect SWTFs and enable it to place a lien on owners that did not manage their facilities.
The County’s Watershed Program, advises applicants regarding c.3 requirements, maintains the CFD for the SWTFs, and inspects them annually
(for public projects) and every 3 years for private properties that are annexed into the SWTF CFD.
(3) How water quality effects and mitigation measures are addressed in environmental reviews: The County’s Department of Conservation
(DCD) Current Planning Division and County’s Public Works Department’s (PWD) Environmental Services Division conduct an environmental
impact review of all private and public projects. Project effects to water quality are analyzed specifically in the Hydrology and Water Quality
Section of a standard CEQA Initial Study checklist as well as indirectly in other sections of the checklist such as Biological Resources; for example,
how impacts to water quality might affect special status species. Water quality is also analyzed in federally participating projects through Water
Quality technical studies that support the NEPA process. Project impact avoidance and minimization may include measures such as limitation of
project disturbance area and preparation of a Storm Water Pollution Prevention Program (SWPPP) or a Water Pollution Control Program (WPCP)
that identifies potential impacts caused during construction and provides recommendations to minimize those impacts. Additionally, potential
long-term effects caused by new and impervious surfaces are addressed through the Contra Costa County Clean Water Program (C.3
Guidelines) and regulatory permitting through the State and Regional Water Boards.
(4) C.3 training for appropriate departments (CCCWP will report on training at the countywide level);
(5) Outreach/education efforts to staff, developers, contractors, construction site operators and owner/builders: The C.3 guidelines available on
the Contra Costa County Clean Water Program (CCCCWP) website, www.cccleanwater.org. The CCCCWP sponsored an annual c.3 training
workshop for municipal staff, contractors and consultants June 7, 2016. Finally, County Watershed Program staff regularly meets with applicants to
explain the purpose, process, and technical aspects of c.3 requirements with project applicants.
(6) How County encourages site design measures at unregulated projects subject to Planning/Building Department review: The County has
published a Small Development Project (“C.3 Light”) handbook/guidelines along with a flow chart for the c.3.i (C.3 Light) process that are given
FY 2015-2016 Annual Report C.3 – New Development and Redevelopment
Permittee Name: Contra Costa County
FY 15-16 AR Form 3-2 9/30/16
out at the Dept. of Conservation and Development (DCD)Department’s application counter. The Watershed Planner coordinates actively with
their DCD counterpart regarding site design and source control provisions.
(7) How your municipality encourages source control measures at unregulated projects subject to Planning/Building Department review; See prior
response, (6)
(8) General Plan revisions (if needed) to integrate water quality/watershed protection with water supply, flood protection, habitat protection,
groundwater recharge, and other sustainable development principles and policies: Not applicable, as the Contra Costa County General Plan
update (2008) already includes them.

C.3.h.v.(3)(d)-(e) ► Installed Stormwater Treatment Systems
Operation and Maintenance Verification Inspection Program
Reporting
Provide a discussion of the inspection findings for the year and any common problems encountered with various types of treatment systems
and/or HM controls. This discussion should include a general comparison to the inspection findings from the previous year.
Summary:
A total of 10 storm water treatment facilities (SWTFs) for projects, built since the advent of the c.3 requirements, were inspected for FY ‘15-16.
They consisted of 4 public and 6 private projects. Seven projects’ SWTFs inspected were in compliance, with no corrective action required,
while 3 of them are in compliance, but required relatively minor corrective actions. The two common and minor problem encountered was
trash buildup and insufficient mulch and consequent stressing of plants. Inspection results for FY ‘15-16 demonstrate substantially higher levels
of compliance relative to FY ‘14-15. Two follow-up inspections will be required to ensure that operation and maintenance issues are
corrected.
Provide a discussion of the effectiveness of the O&M Program and any proposed changes to improve the O&M Program (e.g., changes in
prioritization plan or frequency of O&M inspections, other changes to improve effectiveness program).
Summary:
During FY ’15-16, Watershed Management Program staff performed more inspections than the permits required . Private projects that have SWTFs
are inspected every 5 years, and public projects with SWTFs are inspected every year. Five projects (including 3 private and 2 public ones) were
inspected immediately following a major precipitation event to ascertain whether drainage rates of the bioretention basins were performing up to
the standard (5 inches/hour).
The County continues to require parties responsible for operation and maintenance of private C.3 facilities to monitor their facilities through
letter requests of property owners to conduct “self-inspections” of their SWTFs. This requirement reminds property owners that they are
responsible for maintenance of facilities on their property, encourages property owners to ask questions about how to care for their C.3
facilities, and allows the County to gather data about issues property owners are having with C.3 facilities and their maintenance Letters and
maintenance forms were sent in September 2015 (with reminder letters sent in October) to all property owners who have SWTFs that have
been annexed into the Community Facilities District (CFD) to conduct inspections and make repairs before the onset of the rainy season
(October 31). Of 15 letters sent, a total of 8 completed self-inspection forms were received back from owners.
C.3.i. ►Required Site Design Measures for Small Projects and
Detached Single Family Home Projects
On an annual basis, discuss the implementation of the requirements of Provision C.3.i, including ordinance revisions, permit conditions,
development of standard specifications and/or guidance materials, and staff training.
Summary: Summary:
FY 2015-2016 Annual Report C.3 – New Development and Redevelopment
Permittee Name: Contra Costa County
FY 15-16 AR Form 3-6 9/30/16
The Contra Costa Clean Water Program adopted the December 1, 2012 addendum to the Stormwater C.3 Guidebook, 6th Edition. The
addendum, “Preparing a Stormwater Control Plan for a Small Land Development Project,” includes step-by-step instructions, a project data form,
and standard specifications for runoff reduction measures. Section 1014 (Stormwater Management and Discharge Control Ordinance) of Contra
Costa County’s ordinance code requires that applications for development approvals for projects subject to the permit’s new development
requirements include a Stormwater Control Plan meeting the criteria in the most recent version of the Stormwater C.3. The County applied the c.3
“Light” (small projects) for 5 projects in this Fiscal Year.
C.3.j.i.v.(d) ► Green Infrastructure Outreach
On an annual basis, provide a summary of your agency’s outreach and education efforts pertaining to Green Infrastructure planning and
implementation.
Summary:
The County’s CWP including Green Infrastructure (GI) Planning as a training topic in its annual c.3 training workshop for mun icipal staff, contractors
and consultants on June 7, 2016. County Watershed Program staff met and/or corresponded with management in the Department of
Conservation and Development Current Planning Division, the Public Works’ Department Transportation Engineering Division, the Public Works
Flood Control Division, the Public Works Airports Division, and the Public Works Department Capital Projects to review their Capital Improvmenet
Plan list and the requirements to Green Infrastructure Planning in their capital improvement plans. County Watershed staff had discussions with
capital projects staff in the Health Services Department and the Employment and Human Services Department. It was determined that the
Capital Improvement Programs in these two Departments involved interior remodels, and not construction of outside impervious surfaces.
Please also refer to the CCCWP’s FY 15-16 Annual Report for a summary of outreach efforts implemented at the countywide level.
C.3.j.ii.(2) ► Early Implementation of Green Infrastructure
Projects
On an annual basis, submit a list of green infrastructure projects, public and private, that are already planned for implementation during the permit
term and infrastructure projects planned for implementation during the permit term that have potential for green infrastructure measures. Include
the following information:
A summary of planning or implementation status for each public and private green infrastructure project that is not also a Regulated
Project as defined in Provision C.3.b.ii. (see C.3.j.ii.(2) Table B - Planned Green Infrastructure Projects).
A summary of how each public infrastructure project with green infrastructure potential will include green infrastructure measures to the
maximum extent practicable during the permit term. For any public infrastructure project where implementation of green infrastructure
measures is not practicable, submit a brief description of the project and the reasons green infrastructure measures were impracticable to
implement (see C.3.j.ii.(2) Table A - Public Projects Reviewed for Green Infrastructure).

Permittee Name: Contra Costa County
FY 15-16 AR Form 3-7 9/30/16
Background Information:
Describe how this provision is being implemented by your agency, including the process used by your agency to identify projects with potential for
green infrastructure, if applicable.
County Watershed Management Staff are using “Guidance for Identifying Green Infrastructure Potential in Municipal Capital Improvement
Projects” Memo by Dan Cloak (May 12, 2016) and have sent this guidance memo to management and high level staff s in the Public Works
Department’s Transportation Engineering Division to help identify projects with GI potential.
Summary of Planning or Implementation Status of Identified Projects:
See attached Tables C.3.j.ii. (2)-A and C.3.j.ii. (2)-B for identification of green infrastructure potential for road and other infrastructure-related
County projects. County Watershed Program staff reviewed the Capital Roads Improvement Projects (CRIP) list with Public Works Department
Transportation Engineering Division staff to review and identify those that met specific GI potential criteria in the aforementioned “Guidance for
Identifying Green Infrastructure Potential in Municipal Capital Improvement Projects” memo; projects identified in Tables C.3.j.ii.(2)-A and B fulfill
these criteria. It should be further noted that three other County Capital Improvement project lists for improvements to other County facilities and
buildings were reviewed. None of them included projects that had 10,000 square feet or more of new or redeveloped impervious surfaces to
qualify for having GI potential. Almost all of them were interior renovation projects.
C.3.j.iii.(2) ► Participate in Processes to Promote Green
Infrastructure
On an annual basis, report on the goals and outcomes during the reporting year of work undertaken to participate in processes to promote green
infrastructure.
Please refer to the CCCWP’s FY 15-16 Annual Report, Section 3 for a summary of efforts conducted to help regional, State, and federal agencies
plan, design and fund incorporation of green infrastructure measures into local infrastructure projects, including transportation projects.

Program Highlights and Evaluation Highlight/summarize activities for reporting year:
Summary:
Contra Costa County, representing the unincorporated county communities, is part of Contra Costa County’s Clean Water Program. Contra
County Watershed Program and Public Works Department (PWD) Maintenance staff participate in Contra Costa Clean Water Program’s
Municipal Operations Committee as well as the Commercial/Industrial Inspection Workgroup.
Staff from the County Health Services Department Hazardous Material Division (Haz Mat) and Environmental Health Division (Env. Health)
conduct industrial and commercial stormwater inspections on behalf of Contra Costa County. The County Watershed Program works with Haz
Mat and Environmental Health to review/update the master facility list and the list of facilities scheduled to be inspected. Inspection
frequencies and priorities are based on Contra Costa County’s Industrial and Commercial Businesses Stormwater Inspection Plan. In FY 15-16, the
County conducted 319 inspections of 293 facilities. More detailed information regarding the inspections is provided in the sections below.
The County works with businesses to attain compliance with storm water regulations. For the businesses with recurring potential or actual storm
water violations, Contra Costa County staff continues to work with facilities to attain compliance and to educate businesses and staff. Inspectors
coordinate with the Watershed Program for guidance and suggestions where problems occur. County staff from different departments work
together to communicate and to coordinate to find long term solutions when problems occur or do not appear to work over time. Staff have
meetings and trainings together as appropriate.
Inspectors and County Watershed staff attended the Annual Commercial/Industrial Inspector Training on May 5, 2016. County Watershed staff
conducted training for the Hazardous Materials and Environmental Health inspectors on the Municipal Stormwater Permit, inspections, and
inspection documentation on September 9, 2015. County Watershed and Hazmat staff conducted training for Public Works Maintenance Staff
on the Storm Water Pollution Prevention Plan and First Responder Training on April 7, 2016.
Refer to the C.4. Industrial and Commercial Site Controls section of the CCCWPs FY 15-16 Annual Report for a description of activities of the
CCCWP’s Municipal Operations Committee and/or the BASMAA Municipal Operations Committee.

Comments:
Contra Costa County records each compliance issue as a distinct violation. Therefore, a site may have multiple violations. The violations cited in
FY 2015-2016 by Haz Mat and Environmental Health Inspectors are described below.
The following summarizes the observed actual discharges:
1. AT&T Construction Group – The stormwater inspector (inspector) noticed erosion of a streambank due to the placement of a sump and hoses to

Section 5 – Provision C.5 Illicit Discharge Detection and Elimination
Program Highlights and Evaluation Highlight/summarize activities for reporting year:
Provide background information, highlights, trends, etc.
Summary:
Illicit discharges are often identified by citizens, Public Work Maintenance staff, Environmental Health staff, or Hazardous Materials staff. When
discharges are identified, staff makes the appropriate contacts for the situation. For example, if hazardous materials are identified or the
substance is unknown, Hazardous Materials staff are contacted.
Hazardous Materials, Environmental Health, Public Works Department Maintenance, and County Watershed staff responded to, referred,
documented and followed up on 68 illicit discharge complaints. Of these, 21 of the incidents reached the storm drains or waterways, and 55 of
68 incidents were resolved within 10 business days or less.
Contra Costa County participates in the Clean Water Program’s Municipal Operations Committee. Staff works with Clean Water Program Staff to
receive and pass on information from the County’s 1-800-No-Dumping line. Additionally, staff work with inspectors and code enforcement officers
to investigate the responsible party of the illicit discharge, determine more information, educate them, and if appropriate, clean up the
discharge, or impose fines, cost recovery, or other measures.
Refer to the C.5 Illicit Discharge Detection and Elimination section of the CCCWP’s FY 15-16 Annual Report for description of activities at the
countywide or regional level.

For example, during one inspection of a site, there may have been both an erosion control violation and a sediment control violation. For this reason, the total number of violations in this table may not match the total number of enforcement actions reported in Table C6.e.iii.1.e.

Description: C.6 Inspections are conducted by inspectors from both the County Department of Conservation and Development (DCD) and by
the Public Works Department (PWD); both DCD and PWD inspector forms are consistent in their reporting. Violation trends are similar to last year’s
with no written warnings or NOV’s issued; only verbal ones (there were two last year; 13 this year).
C.6.e.iii.(4) ►Evaluation of Inspection Program Effectiveness
Describe what appear to be your program’s strengths and weaknesses, and identify needed improvements, including education and outreach.
Description:
Contra Costa County continues to be involved in both the Contra Costa County Clean Water Program’s Development Committee and the Bay
Area Stormwater Management Agencies Association’s Development Committee. Please refer the C.6 Construction Site Control section of the
CCCWP’s FY 15-16 Annual Report for a description of activities at the countywide or regional level.
Enhancements originally made in PY 12-13, were continued in the current period for the Contra Costa County inspection program:
Training sessions have been conducted for County Watershed Program staff and for Grading Inspectors who are with Building Inspection
of the Department of Conservation and Development (DCD) and for Construction Inspectors with the Public Works Department (PWD) at
58
Calculated as number of violations fully corrected in a timely period after the violations are discovered divided by the total number of violations for the reporting year. 59
Calculated as number of violations not fully corrected within 30 days after the violations are discovered divided by the total number of violations for the reporting year. 60
The total number of violations reported in the table of Violation Correction Times equals the number of initial enforcement actions, i.e., this assumes one violation is issued for several problems during an inspection at a site. The total number of violations in the table of Violation Correction Times may not equal the total number of enforcement actions because one violation issued at a site may have a second enforcement action for the same violation at the next inspection if it is not corrected.

the close of the rainy season every two years. This year’s took place on June 14, 2016 (see below for details about the topics covered).
There was a C.3 related workshop/training that included inspection updates.
The method for tracking inspections of projects continues to track separately inspections conducted by different departments, notably
DCD and PWD, and inspections conducted within different sections of an overall project. This ensures that there is continuity of
inspections by the same inspector for follow-up of construction site issues, and should increase the number of construction site stormwater-
specific inspections overall that are conducted for larger projects with discrete sub-projects.
The County Watershed Program has provided inspectors with guidance regarding designation of High Priority projects and participates in
the final c.6 inspections.

IPM Tactics and Strategies used:
The County’s IPM Committee developed a form for documenting pest management decision making process. Since then, the Departments have
been using this form to document decisions for various pests. This year, the Public Works Roadside and Flood Control Maintenance Division
developed a document for grazing as a vegetation management tool. The Committee recommends that the Departments continue to use the
form to document pest management decisions in the Departments. In this fourth and historically worst year of drought in California, the IPM
Advisory Committee made recommendations to the Board of Supervisors on increasing the use of sustainable landscaping and reducing turf
around County buildings. The Grounds Division undertook a pilot turf conversion at the Pittsburg Health Center where about 70% of the turf was
removed and replaced with drought-tolerant and mulched landscaping. This project is estimated to save one million gallons of water per year
while greatly reducing the need for pesticides.
C.9.b ►Train Municipal Employees
Enter the number of employees that applied or used pesticides (including herbicides) within the scope of their duties this reporting

C.9.c ►Require Contractors to Implement IPM Did your municipality contract with any pesticide service provider in the reporting year? X Yes No
The IPM Coordinator and the County's contractor work together closely and discuss difficult issues that arise. The IPM Coordinator often provides
advice and research for the contractor. The IPM Coordinator reviews each work order requesting service of the County's contractor and is in
regular contact with the contractor about the progress of the structural IPM program. The IPM Coordinator approves the short list of pesticides that
can be used to combat pests in buildings (mainly baits and botanical oils) without posting and reviews and approves requests from the contractor
for the occasional use of pesticides not on that list for unusual pest situations. The contractor sits on the County's IPM Advisory Committee and its
subcommittees, reports at each meeting, and receives guidance from the Committee.
C.9.d ►Interface with County Agricultural Commissioners
Did your municipality communicate with the County Agricultural Commissioner to: (a) get input and assistance on
urban pest management practices and use of pesticides or (b) inform them of water quality issues related to
pesticides, X
Yes
No
If yes, summarize the communication. If no, explain.
Refer to the CCCWP’s FY 15-16 Annual Report, Section C.9 Pesticide Toxicity Controls for a summary of the CCCWP’s communication with Contra
Costa County Agricultural Commissioner.
