Staff Review: April 15, 2013
While the project appears to not require sprinklers based upon proposed addition
and remodel, the project is close. Be advised where more than one (1) addition
and/or alteration for which building permits are required are made within a finro (2)
year period and said alterations are made to the premises of the same occupant. In
such circumstances, the sum of these additions and/or alterations construction costs
during this two (2) year period shall be aggregated for the purpose of calculating the
replacement cost value formula. Final determination will be made and the plan
review phase of the project.
It is very important that you understand the threshold indicated by BMC §17.04.030.
Designer, contractor, and owner should communicate specifically the extent of
demolition and remodel. Keeping in mind any change orders and addendums
which increase the total amount of square footage added or remodeled after
plan review would be applied to the sprinkler ordinance.

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 impacts,
especially during installation, 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 #o prevent prohibited
discharges to storm drains.
During Installafion �
� 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 Discharge 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 Storm drain inlet is blocked to prevent

During Maintenance �
Implement the following BMPs during routine maintenance 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.
