permit, such as treatment of the flows prior to discharge, depending on the particular site conditions. Discharge of the groundwater generated during dewatering to the sanitary sewer or storm drain system shall only occur with authorization of and required permits from the applicable regulatory agencies, including the Bayshore Sanitary District or the RWQCB. Site dewatering activities shall also be monitored by a state licensed geotechnical engineer in such a manner as to avoid the potential for damaging buildings or infrastructure due to potential subsidence of the ground surface in accordance with any requirements from the City Engineer.

 

Page 4.H-25    UPC 2-13 [See page 5-532 for the original comment] REVISE Mitigation 4.H- 1c as follows.

 

Mitigation Measure 4.H-1c. Applicants for site-specific development projects to be constructed within the Baylands Project Site shall prepare and implement a Final Stormwater Management Plan (SMP) in accordance with the most recent NPDES C.3 requirements to be reviewed and approved by the City Engineer prior to approval of final design plans. The SMP shall be prepared by licensed professionals and act as the guiding document detailing best management practices for mitigating water quality impacts in the post-construction phase. Industrial uses shall prepare a SMP in accordance with NPDES permit requirements for Industrial Activity.

Industrial applicants shall include management measures that will achieve the performance standard of best available technology economically achievable and best conventional pollutant control technology in accordance with the General Industrial Permit as approved by the RWQCB and shall demonstrate compliance within an annual report be submitted each July 1. The SMP shall provide operations and maintenance guidelines for all of the BMPs identified in the SMP, including LID measures and other BMPs designed to mitigate potential water quality degradation of runoff from all portions of the completed development, and shall clearly identify the funding sources entity responsible for the required ongoing maintenance. The SMP shall be developed in conjunction with the Storm Drain Master Plan to ensure that the treatment designs support the hydraulics and hydrology of the proposed storm drainage system.

 

Page 4.H-30    BBCAG-315[See page 5-152 for the original comment] REVISE Mitigation Measure 4.H-4a as follows.

 

Mitigation Measure 4.H-4a: Prior to issuance of a building permit, all site-specific development plans within the Project Site shall include systemwide drainage improvements that shall accommodate all increased runoff in accordance with City requirements and correct known existing deficiencies (e.g., Levinson Overflow Area and the PG&E property). On- site storm drainage collection facilities shall be sized to convey the peak

flow rate from a 25-year storm event entirely within the piping system such that Baylands roadways and recreational facilities are not flooded.

Drainage improvements shall accommodate the 100-year peak storm event
