NEW DEVELOPMENT & CONSTRUCTION CONTROLS
NEW DEVELOPMENT & CONSTRUCTION CONTROLS
QUALITATIVE RESULTS
Municipality: City of Walnut Creek
Permit Year: (2007/2008)
Introduction:
The City of Walnut Creek is committed to meeting its NPDES permit provisions in new
developments and reconstructions, including the new development runoff and
Hydrograph Modification Plan (HMP) requirements. The City cooperated in many
countywide initiatives. Two City staff members participated in the Provision C.3
Implementation Work Group and the New Development and Construction Control
Committee. They dedicated numerous hours to formulate new policies and procedures
that would guide implementation countywide. In this permit year, they reviewed the
fourth edition of the Contra Costa “Stormwater C.3 Guidebook” and Request for
Proposals (RFPs) for a soil environmental consultant.
Throughout the year, the NPDES Coordinator worked with Engineering staff and
inspectors to develop standard guidelines related to the operation and maintenance of
stormwater facilities. They jointly prepared an inspection card to be used by Engineering
inspectors to verify the construction of stormwater treatment facilities. The card listed
several milestones (such as site layout, underground pipe installation, soil media mix
testing, and others) where both the assigned project engineer and inspector will need to
sign off on the card before a contractor can proceed to the next stage in construction.
On a regular basis, the NPDES Coordinator met with Engineering and Planning staff to
discuss how the countywide model guidelines can be translated into practical City
policies and procedures. City staff added new conditions of approval for projects
covered under Provision C.3 and HMP requirements and modified the City’s Stormwater
Ordinance accordingly. The “bucket field test,” an informal method to test soil mix
developed by the City’s Engineering staff, has been used by agency members of the
Contra Costa Clean Water Program (CCCWP). The test provides contractors and field
inspectors a quick indicator of whether the soil mix media is within the approved
parameters for soil absorption – a critical factor to an effective stormwater treatment
facility.
Engineering and Planning staff continued to educate developers, contractors, and
construction superintendents of pollution prevention and new Provision C.3
requirements at the early stage of the planning process. Providing excerpts of the
Contra Costa “Stormwater C.3 Guidebook” and informational meetings were some ways
staff communicated the Permit provisions to project applicants during pre-design stage.
Engineering inspectors were trained in erosion and sediment control measures. They
paid closer attention to projects over one acre of land disturbance with State General
Construction permits from the State Water Resources Board. Before the start of the
NDCC - 1
rainy season, Engineering inspectors inspected projects with active grading permits to
ensure that adequate erosion and sediment control measures were installed. There
were 23 projects with active grading permits in this permit year.
In reviewing projects that were covered under Provision C.3, staff emphasized
preserving existing vegetation by minimizing land disturbance, incorporating clustered
development, and implementing low-impact development principles. Natural vegetation
provides filtration of pollutants and silts, controls erosion, protects water quality, and
provides aesthetic values to the project. In this permit year, seven projects received
approved Stormwater Control Plans and twelve other projects covered under Provision
C.3 requirements were in various stages of tentative map review, permit review, and
construction.
Beginning in late August, the NPDES Coordinator mailed letters to project
superintendents reminding them to prepare and submit erosion control plans for
approval by the City. The City’s General Notes for Erosion Control require that all
projects with active grading permits must install erosion and sediment control measures
by October 15. One Stop Work Order was issued to a project that failed to prepare and
install erosion and sediment control measures by the deadline. The City’s Engineering
inspectors visited every construction project before the start of the rainy season and
after each significant event. The NPDES Coordinator submitted a report to the San
Francisco Regional Water Quality Control Board verifying that all active construction
projects with issued grading permits had been inspected and were found to be in
compliance with effective erosion control measures. Throughout the rainy season,
projects with ineffective or failing erosion control measures were required to correct the
deficiencies.
All contractors working for the City were required to implement effective stormwater
Best Management Practices (BMPs) for construction sites. Each plan of a Capital
Investment Plan (CIP) project includes a copy of the Stormwater Construction BMPs for
contractors to follow. At a minimum, contractors are required to place filter materials to
keep debris and sediment from entering the City’s drainage system. Engineering staff
distributed 32 copies of “Blueprint for a Clean Bay” booklets to project applicants and
contractors.
In our ongoing effort to improve the City’s enforcement strategy related to construction
activities, several meetings took place among staff from the Building and Engineering
Divisions to review our current enforcement policies and practices. This dialogue
resulted in streamlining the oversight of development and construction activities.
Implementation & Evaluation:
A.
The City of Walnut Creek incorporated policies and implementation measures
into the recently adopted General Plan 2025 to help preserve and enhance water
quality and protect sensitive areas.
NDCC - 2
The General Plan includes provisions for existing open space, watershed and
creeks, trails, parks, and recreation facilities. The City’s General Plan provides a
blueprint for the City’s Zoning Ordinance by ensuring that there is a consistent
and reinforcing relationship between the two policies.
As outlined in the General Plan document, the City supports a joint planning
effort to develop a “smart growth” response to future change. Smart growth
encourages more mixed-used development within existing urban areas, higher
density, and less automobile-dependent development. Called “Shaping Our
Future”, the project focused on:
 Open space preservation
 Reinvestment in and preservation of existing urban areas and neighborhoods
 Mixed-use development to bring shops, services, and entertainment close to
residential areas
 Encouraging access by walking, biking, and use of public transit system.
The Federal Emergency Management Agency (FEMA) approved the City of
Walnut Creek’s Local Hazard Mitigation Plan in this permit year, assuring
eligibility for federal grants for projects to reduce hazards in advance of natural
disasters. The City Council adopted a resolution to support a regional MultiJurisdictional Hazard Mitigation Plan developed in cooperation with other local
agencies coordinated by the Association of Bay Area Governments (ABAG).
B.
When an applicant initiates a new development or redevelopment project with the
City, Planning staff reviews the project using a comprehensive California
Environmental Quality Act (CEQA) checklist to evaluate its impacts (per
Provision C.3.m). See Attachment ND-1. City planners consider environmental
impacts of factors, such as:
 Biological resources
 Hydrology/water quality
 Geology/soils
 Land use/planning
 Public services and many others.
C.
Engineering staff experimented and came up with a simple soil testing apparatus
to verify soil qualities at job sites. The simple field apparatus was created by
drilling some holes in the bottom of a five-gallon bucket. The bucket was filled
with soil mix and water to a certain level. Using a timer, staff could determine the
rate of soil permeability. It was noted that the Integrated Management Plan (IMP)
soils need to derive their moisture-holding capacity primarily from the organics,
rather than from fine materials. This method was shared with other agency
members of the Provision C.3 Implementation Committee. Project
superintendents and Engineering inspectors have used this simple test at their
sites to determine if their soils were within an acceptable absorption range.
NDCC - 3
D.
City staff regularly participated in the New Development and Construction
Controls Committee meetings as well as in the Provision C.3 Implementation
meetings. Updated legislation and information received from this committee was
communicated to appropriate City staff. Engineering staff assisted the CCCWP to
review the RFPs for a soil consultant, which will work in refining the field soilmedia mix verification test (as discussed above) from a scientific perspective.
Staff are currently reviewing the fourth edition of the Contra Costa “Stormwater
C.3 Guidebook”’ which is expected to be released after the Municipal NPDES
Regional Permit (MRP) is adopted and its provisions are incorporated. City
Engineering staff came up with two new concepts of IMPs for small-lot project
development, which were shared with the Contra Costa Clean Water Program.
CCCWP is currently contracting with an engineering consultant to prepare a
hydraulic model to develop these IMP designs and specifications.
Seven projects have gone through the entitlement process and received
approvals on their Stormwater Control Plans (see Attachment ND-2). The
following are projects with approved Plans during FY 2007/2008. Their
Stormwater Control Plans (SWCPs) are included in this Annual Report.
 Varian Building (see Attachment ND-2.a).
 2275 Overlook Subdivision (see Attachment ND-2.b).
 Central Contra Costa Sanitary District Corporation Yard Improvements (see
Attachment ND-2.c).
 Walnut Creek Public Library (see Attachment ND-2.d).
 2245 Overlook Subdivision (see Attachment ND-2.e).
 Brian Ranch Subdivision (see Attachment ND-2.f).
 Cole Terrace Subdivision (see Attachment ND-2.g).
The Stormwater Control Plans for the projects listed above were included in this
Annual Report. Section IV of each plan includes information on the party
responsible to operate and maintain the facilities, type of source controls, and
treatment controls that were installed.
The City’s public library will include a number of source controls on-site that merit
mention. Among them are storm drain stenciling; interior floor drains and elevator
shaft sump pumps connected to the sanitary sewer; covered parking garage floor
drains plumbed to the sanitary sewer; refuse area BMPs; and use of Integrated
Pest Management (IPM) practices in their landscape maintenance. In addition, a
number of self-retaining planters and grassy swales will be installed to treat onsite runoff from the library and its surface parking lot.
E.
Attachment ND-3 lists 12 projects that were subject to Provision C.3 in FY
2007/2008. Three projects had Stormwater Control Plans approved in the
previous year – they were either in a construction stage or in site development
permit review. Nine other projects were either in a tentative map process or in a
planning review stage. These projects ranged from multi-family residence to a
hospital and a corporation yard.
NDCC - 4
In addition to meeting Provision C.3 requirements with low-impact development,
John Muir Medical Center will install a facility to treat its groundwater discharge
as required under its State General Permit for Groundwater Discharges. During
earlier monitoring, it was determined that the project’s groundwater discharge
contains a high level of sulfates – a natural occurrence for the area. The hospital
will conduct water quality monitoring of certain parameters at regular intervals
and submit the annual report to the State Regional Water Quality Control Board.
F.
The City of Walnut Creek and other agency members of the Contra Costa Clean
Water Program have been working with staff of BASMAA and the Regional
Water Quality Control Board to develop an MRP in the past three years.
When approved, the new Permit will cover five counties and seventy-six
jurisdictions in the greater San Francisco Bay areas. The regional permit will
create a level playing field among all regulated permittees and pose opportunities
for collaborative efforts in meeting some Permit provisions, such as, water quality
monitoring, special studies, and implementation of the Total Maximum Daily
Loads (TMDLs).
The City’s NPDES Permit expired in 2004 but has been administratively
extended by the Regional Board while the MRP is being developed. In the
process of developing this regional NPDES Permit, staff has reviewed internal
procedures that have not been revised since the original permit, which was
written in 1999. The lengthy annual report and documentation currently required
under the existing permit are too cumbersome to prepare, write, and review. Staff
is proposing a prioritized and integrated Permit that focuses on meeting the
ultimate goals of the Clean Water Act. With this approach, the proposed annual
report can be simplified to capture the improvements regulated agencies have
made, rather than focusing on the lengthy process. The NPDES Coordinator will
continue to support the MRP process as one of the highest priorities. Staff has,
and will continue to, attend all MRP meetings and work groups, and provide
suggestions whenever the opportunity presents.
G.
On October 20, 2007, the City hosted a “Sustainable Walnut Creek: Going Green
Together” summit at the Lesher Center for the Arts. The purpose of the event
was to share information and creative ideas on the many ways we can improve
the local and global environment, and to become inspired so that we might take
action on our own. Residents and business owners could asks questions related
to carbon footprints, the Kyoto protocol, LEED-certification, photovoltaics, and
many more sustainable measures. The City’s Clean Water program was among
the exhibitors participating at this summit.

Based on a citizens’ survey conducted by the City through the National Research
Center in Spring of 2007, most Walnut Creek residents said they would be likely
to do a variety of things themselves to improve the environmental quality of life in
Walnut Creek.
The following is a summary of the survey:
Residents are likely to patronize a “green” business
Residents are likely to properly dispose of or recycle
household batteries
Residents are likely to reduce the use of their woodburning fireplace
Residents are likely to replace standard light bulbs
with energy-efficient bulbs
Residents are likely to reduce landscape watering
Residents are likely to park once downtown and use
the Free Ride trolley
Residents are likely to use a commute alternative
(carpool, transit, biking, etc.)
Residents are likely to time their car trips to avoid
commute hour traffic
Residents are likely to use a commercial car wash
rather than wash at home

The City’s commitment to sustainability was shown in its dedication to have
“Going Green Together” columns in every In a Nutshell newsletter. The City
helped organize a “Build It Green” home tour on June 1, 2008, that gave a
glimpse inside some of the East Bay’s greenest homes. In May of 2008, a
number of visitors from other jurisdictions along with City Engineering, Planning,
and Building staff toured the recently constructed Villa Vasconcellos housing
development - a new 70-unit apartment building for extremely low and very-low
income seniors.
The project was an example of a green building. Although it was not covered
under Provision C.3 requirements, it installed many notable “green”
improvements, such as, dry cisterns and permeable pavers to capture rain
waters. Common-area electricity and hot water were provided through solar
power. It installed Energy Star appliances, low E windows, and drought tolerant
landscaping. The complex, which opened in February, was designed for seniors
over 55 years old. All units are affordable to low- income people. The City
provided funding of $2.6 million through its Community Development Block Grant
program to help make the $19-million project possible.

H.
The NPDES Coordinator met with other City staff regularly to discuss
implementation of Provision C.3 and HMP. Planning staff is updating its project
checklist to ensure that Provision C.3 requirements are communicated to project
applicants at the earliest possible stage.
As a project begins the development process, it is reviewed by Building,
Planning, Engineering, and Traffic Engineering staff. Early in this stage, the
applicant is informed of recommended and required measures, such as, reducing
pervious surfaces, directing more surface runoff to landscaped areas, and
installing post-construction BMPs.
City’s Preliminary Review Team meets weekly to provide a cursory preapplication review of projects. Initial feedback is provided to the developer by
Planning, Engineering, Building, and Transportation Division staff members. At
this meeting, staff directs developers of residential projects to consider site
planning and design BMPs, such as clustering units, minimizing hillside grading
by possibly relocating houses, and minimizing impervious surface. Developers of
commercial projects are asked to replace existing pavement and concrete
surfaces with landscaped areas and interlocking pavers. Developers of projects
subject to Provision C.3 are also informed of these requirements. Additional
information was entered for projects subject to Provision C.3 in the PermitsPlus
database system. When these projects are completed, staff will enter the
information related to the operation and maintenance obligations of the
constructed stormwater treatment facilities (see Attachment ND-5.)
I.
In October 2007, three Engineering staff attended a regional “Rein in the Rain”
Provision C.3 and Hydrograph Modification workshop in Shadelands Civic Arts
Center. Two Engineering staff attended a low-impact development training in
Oakland. The workshops, sponsored by CCCWP and Bay Area Stormwater
Agencies Association (BASMAA) respectively, covered all Provision C.3
requirements and addressed the need to integrate stormwater treatment facilities
into a preliminary site layout and landscape designs, preparing a Stormwater
Control Plan, using the IMP sizing calculator, and participating in a walk-through
design exercise in smaller-group setting.
J.
In November 2007, ten Engineering, Building, and Maintenance staff attended a
construction inspection workshop hosted by the Contra Costa Clean Water
Program. The attendees learned about inspecting a construction project to
assure effective erosion and sediment controls. Examples of proper installation of
these control measures were highlighted. Following the workshop, staff went on
a field trip to a new Rose Garden commercial development in Danville to observe
recently constructed stormwater IMPs. The field trip provided useful information
to assist staff in evaluating what IMP designs work effectively and identify any
pitfalls. Attachment ND-11.a includes the agenda for this workshop. Attachment
ND-11.b includes the Inspectors’ Training certificates.
NDCC - 7
K.
Recognizing the importance of incorporating stormwater runoff control
requirements at the earliest stage possible, the City continues to provide
informational brochures on Provision C.3. (See Attachment ND-12 for a copy of
the Fact Sheet.) Planning and Engineering staff have distributed this brochure to
permit applicants at design review meetings and communicated the potential
requirements on applicable projects to project architects and engineers.
Furthermore, staff continues to provide an informational memo to developers
addressing the new HMP requirements adopted by the Regional Board last fiscal
year.
As the City encountered more projects subject to Provision C.3, one major
challenge faced by City Engineering staff and inspectors was to ensure these
facilities were installed appropriately. Lack of approved standards for accepting
the soil-mix media in the field was identified as the biggest concern. Adequate
site layout for placement of these facilities was the second concern raised by the
inspector.
With the City’s being held responsible by the Regional Board to ensure effective
operation and maintenance of these structures in perpetuity, staff recognized the
important of their construction according to the approved plan. A slight deviation
in the actual grading of a bio-swale can cause water retention longer than
necessary – possibly creating a mosquito-breeding habitat.
For the past two months, the NPDES Coordinator worked with Engineering staff
and inspectors to discuss different ways to provide adequate oversight during the
installation of these structures. As a first try, staff jointly produced an inspection
card with various milestones for each construction stage. The idea was for both
the Engineering staff and inspector assigned to the project to sign off on each
critical step before the contractor can proceed to the next stage in the
construction (see Attachment ND-6.) The card provides documentation for the
Stormwater Control Plan file of the project that both the developers and City staff
have done their due diligence to ensure proper installation of these facilities.
L.
The City has standard Conditions of Approval (Attachment ND-4) and other
permitting policies that contain requirements to meet the NPDES Permit.
Examples include submitting a Notice of Intent (NOI) to the State Water
Resources Control Board, preparing a Storm Water Pollution Prevention Plan
(SWPPP) for construction projects over one acre, and having erosion and
sediment controls in place for active construction during wet weather.
During this permit year, there were ten projects disturbing a minimum of one acre
that were required to prepare SWPPPs for City review. As a follow-up, a
reminder letter was mailed to project applicants of any outstanding issues to
resolve. (See Attachment ND-14 for a list of projects with active SWPPPs.)
NDCC - 8
M.
City staff requires project applicants to incorporate source controls, design
measures, and treatment controls to minimize stormwater pollutant discharge
and to limit peak runoff leaving the site to match with the pre-development flow to
minimize downstream erosion. All new development projects with trash areas are
required to cover and enclose them and provide perimeter grades that prevent
water run-on/runoff. As a post-construction practice, we require developers to
place “NO DUMPING – DRAINS TO CREEK” permanent decals on storm drain
inlets. Other control measures include underground detention, bio-swales,
infiltration planters, retention basins, and inlet filters.
Engineering staff attached the Construction Site BMPs plan sheet to project bid
packages and included a separate line item for related expenses. Building
Division staff attached the Construction Site BMPs plan sheet to all projects
requiring building permits. This is to ensure contractors are aware of potential
sources for stormwater pollution in building-construction-related activities.
N.
Provision C.3.e required that Walnut Creek compile a list of properties (both
public and private) and responsible owners for all the stormwater treatment
measures. Since most are within private properties, the responsibility of
operation, inspection, and maintenance lies with the property owners. The City
requires the project owner to execute Stormwater Facilities Operations and
Maintenance (O&M) and Right of Entry Agreements. In addition to outlining the
owner’s responsibilities, the agreements allow City staff to enter the premises
and inspect the facility.
Recommendation(s) from the Provision C.3 Legal Work Group will influence how
the City requires private developments to address operation and maintenance of
the facilities. Currently, the Work Group is using Sunnyvale Estates, a residential
subdivision in Walnut Creek, as its case study.
O.
Per Provision C.3.iv, Engineering staff will track the number of post-construction
BMPs implemented through private and public development projects. Once a
permit is issued, the assigned project engineer will enter the information related
to the treatment facilities (such as the type, location, inspection and maintenance
schedule, and the responsible party) into an Excel spreadsheet. Eventually, this
information will be uploaded as a GIS layer for tracking. At the end of the fiscal
year, the list of treatment facilities will be forwarded to the Contra Costa County
Mosquito and Vector Control District, as appropriate.
P.
The City has a comprehensive erosion control program. All projects disturbing
the existing grade between October 1 and April 15 are required to implement
erosion control measures. The City’s Improvement Plan Checklist addresses
Erosion Control Plans. The City also has standard erosion control notes, which
must appear on all Erosion Control Plans.
NDCC - 9
By September 2006, Engineering staff distributed reminder letters to project
superintendents and applicants to submit Erosion Control Plans and to install
proper control measures by October 1. This requirement also applied to City
projects as stated in the project’s contract specification documents. In FY
2007/2008, there was one Stop Work Order and two verbal warnings issued for
not submitting an erosion and sediment control plan by the deadline. The
requirement to prepare and submit an Erosion Control Plan is reiterated at the
mandatory pre-construction meetings. (See Attachments ND-8.a and ND-8.b for
samples of Erosion Control Plan reminder letters and Attachment ND-9 for
copies of Pre-Rainy Season Inspection forms.)
Q.
Engineering inspectors monitored construction sites regularly to ensure
adequacy of stormwater quality control measures. They also inspected those
sites that were issued site development permits prior to the beginning of the wet
season to ensure implementation and maintenance of proper erosion/sediment
controls. When inspecting a project during the rainy season, they used a
standardized inspection form to verify whether control measures were adequate
and properly maintained. (See Attachment ND-10.)
R.
During this permit year, we had 40 new site development permits as well as
approximately 10 site development permits carried over from previous years. Of
these active permits, 23 involved site grading and remained active during wet
weather, requiring erosion control plans to be implemented. The City Council
awarded 31 capital investment projects, 10 of which related to building
maintenance works; 15 projects were construction-related activities, and 6 were
miscellaneous projects.
A total of 920 drive-by and on-site inspections were performed on 40 projects
during the rainy season. This is an average of 23 drive-by and on-site inspections
per site between the months of October and April. Due to early education
regarding erosion and sediment control measures, the number of projects out of
compliance has been reduced. Six verbal warnings and one Stop Work Order
were issued for non-compliance during the rainy season. Engineering staff
issued a Notice of Violation to a contractor working on a CIP overlay project for
not removing the temporary inlet protection after the project was completed. On
average, our inspectors conducted at least ten field inspections for each
construction project during the dry season.
S.
When an Engineering inspector determines that a project fails to install the
required control measures, enforcement action is initiated. The inspector gives a
verbal warning to the contractor if currently on site. Verbal warnings were
effective in providing timely compliance approximately 90 percent of the time. If
the contractor is unavailable or non-responsive, the Engineering inspector issues
a Warning Notice and arranges for a joint inspection to be done within 24 hours.
NDCC - 10
If corrective actions are not implemented by the deadline, a Stop Work Order is
issued to the project. No other construction activities are allowed until the
conditions are satisfied.
T.
When the same project fails to maintain the conditions of approval during
construction, our Engineering inspector has the flexibility to forgo issuing the
Warning Notice and can directly issue a Stop Work Order. With the issuance of a
second Stop Work Order, all contractors, sub-contractors, and project owners are
required to attend a meeting with City staff to go over the issues.
All enforcement actions are documented by the Engineering inspector and
Engineering staff assigned to the project and become part of the project file. If
necessary, the document is sent to the appropriate regulatory agency. It has
been a practice for Engineering staff to carbon copy the Regional Water Quality
Control Board when writing a reprimand letter or Stop Work Order.
Modifications:
None proposed.
Fiscal Year 2008/2009 Goals:
A.
Participating in the work groups to review and comment on the proposed
Municipal NPDES Regional Permit (MRP) released by the San Francisco Bay
Regional Water Quality Control Board.
B.
Goals for the City’s Clean Water Program will depend on what new provisions
will be required once the proposed Permit is adopted by the State.
