OF INTENT TO ADOPT AN INITIAL STUDY/ PROPOSED
MITIGATED NEGATIVE DECLARATION
Date: June 20, 2019
Project Name: Orange Memorial Park Water Capture Project
Notice is hereby given that the City of South San Francisco has released an Initial Study and
Proposed Mitigated Negative Declaration (IS/MND) for public review for the Orange Memorial
Park Water Capture Project (Project).
Project Description: The proposed Project would result in the construction and operation of a
water capture facility through the installation of a drop inlet, diversion channel, and inlet
junction structure (trash screen) in the upper and western end of the Colma Creek channel and
Orange Memorial Park (Park). Captured water would be diverted into a series of storm pipes
and pretreatment chambers that would lead to an underground stormwater storage reservoir
in the southeastern corner of the Park. A portion of the storage would function as a cistern
holding water for eventual non-potable irrigation use in and around the Park, and the
remainder would function as an infiltration chamber. These storage facilities would be
constructed underneath a portion of two existing Park ballfields.
When storage capacity is exceeded, overflow from the system would be routed through an
infiltration chamber before being metered back into the channel. The Project would provide
water quality improvements to meet the National Pollutant Discharge and Elimination System
(NOPES) requirements of the San Francisco Bay Municipal Regional Permit associated with a
reduction in pollutant discharges of PCBs, mercury and trash to San Francisco Bay to comply
with Total Maximum Discharge Load (TMDL) requirements. This regional project would also
reduce localized flooding and reuse treated water for irrigation and groundwater recharge. The
Project would capture and treat 8 to 16 percent of the annual drainage from approximately
6,500 acres of land in the City of South San Francisco, Town of Colma, the City of Daly City, and
a portion of unincorporated San Mateo County. Following construction, the open picnic areas
would be graded and restored and the two ballfields would be restored with new turf.
Project Location: The proposed Project is located along Colma Creek within the southern half of
the Park, a 28-acre public park located at 1 West Orange Avenue, in the City of South San
Francisco, California. The City of South San Francisco lies within San Mateo County in the San
Francisco Bay Area. The Project would be entirely confined within the Park, which supports a
range of recreational facilities including two formal ball fields. The limits of the proposed
Project water capture facilities would extend approximately 1,000 feet from the upstream and
western end of Colma Creek to the southeast corner of the Park near the two ballfields located
along West Orange Avenue.
Environmental Effects: The City of South San Francisco has prepared an IS/MND pursuant to
the California Environmental Quality Act (CEQA) Guidelines Section 15063 and 15071. The City
of South San Francisco has studied the effects of the proposed Project may have on the
environment. Based on this IS, the design measures incorporated into the project, and
proposed mitigation, the proposed Project would not result in significant environmental
impacts. Therefore, an IS/MND is proposed for compliance with the requirements of CEQA.
Public Review Period: You are invited to review the Draft IS/MND and provide comments. The
City will provide a 30-day public review period for the IS/MND from June 21, 2019 to July 22,
2019 pursuant to CEQA Guidelines Section 15105.
