indicates that the project does trigger the new stormwater requirements. These
requirements appear to be satisfied by measures indicated on the checklist (c., d., e.)
and on th� plans.
2) The checklist indicates that there is no Architectural Copper to be used in the
project however there is a copper roof and it is stated on the plans that the drain
w�ter is to be routed to landscaping. The Architectural Copper Best Management
Practices (BMP) sheet is provided on page PW.1 of the plans.

Drive, zoned R-1, APN: 027-154-160
Staff Review: March 4, 2013
�Effective-Dec 1, 2012, stormwater requirements are required to be implemented at
tand-alone single family home projects that create and/or replace 2,500 sq.ft. or
more of impervious surface. These requirements are in addition to any City
requirements. To determine if �his project is subject to those requirements complete
and return the attached "Stormwater Checklist for Small Projects." For additional
information about these requirements please refer to the attached flyer "New
Stormwater Control Requirements Effective 12/1/12" and by visiting the San Mateo
County Stormwater Pollution Prevention Program (SMCWPPP) website at:
hftp://flowstobay.org/bs_new_development. php#flyers
2) Any construction project in the City, regardless of size, shall comply with the City's
NPDES (stormwater) permit to prevent stormwater pollution from construction
activities. Project proponent shall ensure all contractors implement appropriate and
effective BMPs during all phases of construction, including demolition. When
submitting plans for a building permit include a list of construction BMPs as project
notes on a separate fuil size plan sheet, preferably 2' x 3' or larger. Project
proponent may use the attached Construction BMPs plan sheet to comply with this
requirement. Electronic file is available for download at:

3) Best Management Practices (BMPs) requirements apply on any projects using
architectural copper. To learn what these requirements are, see attached flyer

sewers, and contain by berms or similar.
• Roofed, pave and berm wash area to prevent stormwater run-on and runoff,
plumb to the sanitary sewers, and sign as a designated wash area.
• Commercial car wash facilities shall discharge to the sanitary sewer.s
• Designate repair/maintenance area indoors, or an outdoors area designed to
prevent stormwater run-on and runoff and provide secondary containment. Do
not install drains in the secondary containment areas.
• No floor drains unless pretreated prior to discharge to the sanitary sewer. 6
• Connect containers or sinks used for parts cleaning to the sanitary sewer. 6
� Fueling areas shall have impermeable surFace that is a) minimally graded to
prevent ponding and b) separated from the rest of the site by a grade break.
■ Canopy shall extend at least 10 ft in each direction from each pump and drain
away from fueling area.

D.1 Is the site a"High Priority Site"? (Municipal staff will make this determination; if the answeris yes, Yes ❑ No ❑
the project will be referred to �ensfruction site inspection s+aff for monthly stormwater inspections
during the wet season, October 1 through Apri130.)
•"High Priority Sites" are sites that require a grading permit, are adjacent to a creek, or are
otherwise high priority for stormwater protection during construction per MRP Provision C.6.e.ii(2).
D.2 All projects require appropriate stormwater BMPs during construction, indicate which BMPs are included in the project, below.
Yes No Best Management Practice (BMP)
❑ ❑ Attach the San Mateo Countywide Water Pollution Prevention Program's construction BMP plan sheet to
project plans and require contractor to implement the applicable BMPs on the pian sheet.
❑ ❑ Temporary erosion controls to stabilize all denuded areas until permanent erosion controls are established.
❑ ❑ Delineate with field markers clearing limits, easements, setbacks, sensitive or critical areas, buffer zones,
trees, and drainage courses.
❑ ❑ Provide notes, specifications, or attachments describing the following:
• Construction, operation and maintenance of erosion and sediment controls, include inspection frequency;
• Methods and schedule for grading, excavation, filling, clearing of vegetation, and storage and disposal of
excavated or cieared material;
• Specifications for vegetaYive cover & mulch, include methods and schedules for planting and fertilization;
• Provisions for temporary and/or permanent irrigation.
❑ ❑ Perform clearing and earth moving activities only during dry weather.
❑ ❑ Use sediment controls or filtration to remove sediment when dewatering and obtain all necessary permits.
❑ ❑ Protect all storm drain inlets in vicinity of site using sediment controls such as berms, fiber roils, or filters.
� � Trap sediment on-site, using BMPs such as sediment basins or traps, earthen dikes or berms, silt fences,
check dams, soil blankets or mats, covers for soil stock piles, etc.
❑ ❑ Divert on-site runoff around exposed areas; divert off-site runoff around the site (e.g., swales and dikes).
❑ ❑ Protect adjacent properties and undisturbed areas from construction impacts using vegetative buffer strips,
sediment barriers or filters, dikes, mulching, or other measures as appropriate.
❑ ❑ Limit construction access routes and stabilize designated access points.
❑ ❑ No cleaning, fueling, or maintaining vehicles on-site, except in a designated area where washwater is
contained and treated.
❑ ❑ Store, handle, and dispose of construction materials/wastes properly to prevent contact with stormwater.
❑ ❑ Contractor shall train and provide instruction to all employees/subcontractors re: construction BMPs.
� � Control and prevent the discharge of all potential pollutants, including pavement cutting wastes, paints,
concrete, petroleum products, chemicals, washwater or sediments, rinse water from architectural copper, and
non-stormwater discharges to storm drains and wate�courses.

Requirements for Architectural Copper
Protect water quality during installation, cleaning, treating, and washing!
Copper from Buildings May Harm Aquatic Life
Copper can harm aquatic life in San Francisco Bay. Water that comes
into contact with architectural copper may contribute to irrrpacts,
especially during installat��n, cleaning, treating, or washing. Patination
solutions that are used to obtain the desired shade of green or brown
typically contain acids. After treatment, when the copper is rinsed to
remove these acids, the rinse water is a source of pollutants.
Municipalities prohibit discharges to the storm drain of water used in the
installation; cleaning, treating and washing of architectural copper.
Use Best Management Practices (BMPs)
The following Best Management Practices (BMPs) must be implemented to prevent prohibited
discharges to storm drains.
During Installation
• If possible, purchase copper materials that have been pre-patinated at the factory.
• If patination is done on-site, implement one or more of the following BMPs:
o Dischargz the rinse water to landscaping. Ensure that the
rinse water does not flow to the street or storm drain.
Block off storm drain inlet if needed.
o Collect rinse water in a tank and pump to the sanitary
sewer. Contact your local sanitary sewer agency before
discharging to the sanitary sewer.
o Collect the rinse water in a tank and haul off-site for
proper disposal.
• Consider coating the copper materials with an impervious
coating that prevents further corrosion and runoff. This will
also maintain fhe desired color for a longer time, requiring
less maintenance.
During Maintenance
Implement the following BMPs during routine mainfenance activities, such as power washing the roof,
re-patination or re-application of impervious coating:
• Block storm drain inlets as needed to prevent runoff from entering storm drains.
• Discharge the wash water to landscaping or to the sanitary sewer (with permission from the local
sanitary sewer agency). If this is not an option, haul the wash water off-site for proper disposal.
Protect the Bay/Ocean and yourself!
If you are responsible for a discharge to the storm drain of non-
stormwater generated by installing, cleaning, treating or washing
copper architectural features, you are in violation of the municipal
stormwater ordinance and may be subject to a fine.
