Site work for a mixed-use development in Lakewood, California. Completed plans call for site work for a playground / park / athletic field; and water / sewer project.

Scope of Work The primary purpose of these regional projects is the improvement of water quality of wet and dry weather urban runoff in the downstream receiving waters (i.e. Flood Control Channels and storm drains). This is accomplished primarily by capturing sediments and trash entrained in the runoff and allowing them to settle out. This is supplemented by various monitors, sensors, filters, screens, pumps, settling galleries as well as pre and post treatment systems and water harvesting systems that must be kept in operating condition. The selected firm(s) will operate and maintain the system in such a manner as to capture (within the capabilities of the equipment as designed and installed) 100 percent of dry weather flows and in wet weather and when feasible up to the design capacity of each project per storm event. Tracking and monitoring the amount of water captured and treated is an important component of this project: Twice a year, the respondent shall report the volume of water imputed to the system and the volume of treated water discharged and other related information as requested by the jurisdictional municipality. For the period January through June, the report will be due September 15 of the same year. For the period July through December, the report will be due March 15 of the following year. The respondent shall conduct required Department of Public Health testing for any applicable water harvesting systems, ponds and wetlands that are receiving harvested water and inlet and outlet testing to Municipal Separate Storm Sewer System (MS4) and Coordinated Integrated Monitoring Program (CIMP) requirements where applicable testing.
