1 <br />1.0 OBJECTIVES AND LAGOON DESCRIPTION <br /> <br />1.1 PURPOSE AND OBJECTIVES <br /> <br />The City of Redwood City's Redwood Shores Lagoon is subject to seasonal infestations of <br />aquatic weeds and algae. Aquatic pesticides are employed as a component of pest management. <br />This Aquatic Pesticide Application Plan (APAP) describes the lagoon's operations, Best <br />Management Practices (BMPs), existing aquatic weed control program, and the lagoon's self- <br />monitoring water quality program. This APAP application and NOI are submitted to the <br />Regional Water Quality Control Board for approval in compliance with the monitoring <br />requirements for an NPDES General Permit for the use of aquatic pesticides in Redwood Shores <br />Lagoon. <br /> <br />The objective of this plan is to provide a description of: 1) the lagoon, its operations, and <br />beneficial uses; 2) the aquatic weed and algae problems and the BMPs in place to reduce the <br />frequency and magnitude of the aquatic weed and algae growth; 3) the aquatic pesticide <br />application program; and 4) the water quality monitoring plan associated with aquatic <br />pesticide applications. <br /> <br />1.2 PROJECT LOCATION AND ADMINISTRATION <br /> <br />The Redwood Shores development is located on the Redwood Peninsula along the west shore <br />of San Francisco Bay in the City of Redwood City, San Mateo County (Figure 1). The <br />peninsula is bounded by Belmont Slough to the north, San Francisco Bay to the east, <br />Steinberger Slough to the south, and the Bayshore Freeway to the west. Levees ring the <br />peninsula, since the ground elevations are below that of the higher tides. Within the interior <br />of the Redwood Peninsula lies Redwood Shores Lagoon. The lagoon is a focal point of the <br />development and contributes to the area's visual aesthetics, aquatic habitat, and recreation <br />(boating, swimming, and windsurfing). The lagoon also serves as a stormwater retention <br />pond for the adjacent developing area, storing surface runoff during periods of high tide in San <br />Francisco Bay. The City's Public Works Division administers overall operation and <br />management of the lagoon, in cooperation with the city Department of Parks and Recreation and <br />county, state, and federal oversight agencies. <br /> <br />1.3 DESCRIPTION OF PROJECT WATERS <br />The main portion of Redwood Shores Lagoon is approximately 9,000 feet long. It is oriented <br />in a northeast to southwest direction between Marine Parkway and Redwood Shores <br />Parkway (Figure 2). At the two ends, the lagoon becomes wider (the southwest end of the <br />lagoon is diamond shaped). At mid-length it connects to two smaller lagoons located on either <br />side of Marlin Drive. A recreational area known as Neptune Beach is part of the small <br />lagoon on the southwest side of Marlin Drive. These two lagoons are interconnected under <br />Marlin Drive by small diameter culverts. <br />6.3.A. - Page 166
