2016 Substantial Conformance Review for Individual Maintenance Plan (IMP) and Individual Technical Assessments for Tijuana River Pilot Channel and Smuggler’s Gulch, City of San Diego Site Development Permit No. 1134892, Master Storm Water System Maintenance Program Attachment 1 Individual Maintenance Plan July 1, 2016 8685 Stephanie Bracci Senior Planner City of San Diego Transportation and Storm Water Department, Operations and Maintenance 2781 Caminito Chollas, MS 44 San Diego, CA 92105 Subject: Master Storm Water System Maintenance Program – Tijuana River Valley Channel Maintenance Project Individual Maintenance Plan Dear Ms. Bracci: In conformance with the City of San Diego (City) modified Master Storm Water System Maintenance Program’s (Master Maintenance Program or MMP) amended Site Development Permit (SDP) No. 1134892 and Program Environmental Impact Report (PEIR) Project No. 42891/SCH No. 2004101032, the attached Individual Maintenance Plan (IMP)(2016 IMP)(Attachment A) is submitted as part of the Substantial Conformance Review (SCR) package for maintenance activities associated with the Tijuana River Valley Channel Maintenance Project. Maintenance activities under the MMP that are associated with the Tijuana River Valley Channel Maintenance Project have occurred periodically since 2013. Maintenance activities have generally been conducted between September 15 and March 15 to avoid potential impacts to nesting birds. Formal regulatory approval and implementation of detailed protocol survey mitigation measures have allowed the City to conduct maintenance activities as-needed and weather permitting throughout the calendar year for the Tijuana River Valley Channel Maintenance Project. Accordingly, this 2016 SCR submittal package (2016 SCR) is intended to address maintenance activities conducted in the 2016-2017 maintenance period, which begins September 15, 2016 and ends September 14, 2017 (2016-2017 maintenance period). Maintenance activities conducted under the MMP as part of the Tijuana River Valley Channel Maintenance Project were first conducted in 2013. An SCR package containing an IMP and other associated Individual Assessments (IAs) was approved in January 2013 (2013 SCR) for maintenance in the 2013-2014 maintenance period. A second SCR package, for maintenance in the 2015-2016 maintenance period (2015 SCR), that included an updated IMP (2015 IMP), was approved in July 2015. Existing conditions and mitigation impacts were re-evaluated in spring 2016 in order to assess conditions related to the IMP in advance of the 2016-2017 maintenance period. Conditions remain substantially similar to those described in the 2015 SCR. The 2016 IMP includes a new Water Pollution Control Plan (WPCP), and specific updates to the Construction Plans, Master List of Best Management Practices (BMPs), and the Maintenance Methodology. This letter and attachments serve as the basis for SCR determination for maintenance work in the 2016-2017 monitoring period as part of the Tijuana River Valley Channel Maintenance Project. Project History and Background The Tijuana River Valley Channel Maintenance Project includes maintenance of the Pilot Channel and Smuggler’s Gulch Channel as part of the MMP. The Pilot Channel is included on MMP Maps 138a through 138c and the Smuggler’s Gulch Channel is included on MMP Maps 138 and 139 (City of San Diego 2011). Environmental permits were issued by the California Department of Fish and Wildlife (CDFW), Regional Water Quality Control Board (RWQCB), United States Fish and Wildlife Service (USFWS), Army Corps of Engineers (ACOE), and the California Coastal Commission (CCC) in 2012 and 2013 based on the project scope, impacts, and mitigation. Maintenance activities in the Pilot Channel and Smuggler’s Gulch Channel were conducted in the 2013 – 2014 and 2015-2016 maintenance periods. Appropriate constructionrelated BMPs and concurrent wetland compensatory mitigation have been impl
