REPORT To the Honorable Mayor and City Council From the City Manager June 3, 2002 Subject Redwood Shores Lagoon Management Services Recommendation By Motion authorize Task Order No. 4 to Waterworks Industries, Inc. extending Agreement through February 28, 2003 and increasing funding to $215,000 for environmental engineering services and implementation of the Redwood Shores Lagoon Management Plan. Background In 1999, the City retained the services of Waterworks Industries, Inc. to maintain the Redwood Shores Lagoons in keeping with the Redwood Shores Laqoon Manaqement Plan, approved by the Regional Water Quality Control Board (RWQCB) in 1995. Task Order No. 4 will continue the maintenance services contained in the original agreement; however, with some adjustments designed to meet new requirements from RWQCB to reduce further the dependence on pesticide use to control nuisance vegetation and algae. The scope of services is adjusted to increase the use of hand labor and mechanical harvesting to compensate for the reduced pesticide usage. The cost and scope reflect the following changes: · Increase use of one harvester, on location at all times during heavy growth season, which can begin as early as March through September, and a second harvester available within 24-hours, as per the original Agreement. · Increase the cost of Chemical Application of Herbicide Reward and / or Cutrine from $165.00 per gallon to $175.00 per gallon, · Increase cost of Chemical Application of.Algaecide - Earth Tec from $50.00 to $55.00 · Increase cost associated with recordkeeping and documentation of chemical use and monitoring per the requirements of the Water Quality Monitoring Plan, under the General Permit for Dischargers of Aquatic Pesticides (see explanation below). Under the provisions of the San Mateo Countywide municipal NPDES permit, the cities of Foster City, San Mateo and Redwood City were required to prepare and implement new Maintenance Performance Standards for our respective lagoon systems. In compliance with RWQCB directives, the performance standards explicitly require reduced reliance on chemicals to control nuisance plant growth. The cities jointly submitted the new standards to RWQCB in May 2001. The maintenance performance standards contain provisions that address the areas below, which are also included in the City's Lagoon Management Plan: ° General lagoon management objectives o Lagoon design and improvements ° Water quality monitoring and source control
