Drainage Master Planning & Design Review for North Natomas
City of Sacramento, California

West Yost prepared design standards for drainage pump station design and provided on-call consulting services to the City for drainage master planning of the North Natomas development area. The design standards were used by various design engineers for the design of seven pump stations, numerous detention/water quality basins, and conveyance systems servicing the 5,000-acre development area.

Throughout the project, West Yost worked extensively with City Operations and Management and Engineering staff to define pumping and electrical/instrumentation strategies. These standards include drawing details and sample specifications for pump station design. Key elements included standby generator, automatic trash racks, gravity bypass to detention ponds, and electrical controls. West Yost also worked with various major developers to produce integrated drainage master plans for the area, including pipelines, channels, detention basins, and pumping stations (eight stations). West Yost developed dynamic hydrologic and hydraulic models of the watersheds and detention basins/pump stations using the City’s Stormwater Management Model program. West Yost also served in a design review capacity for developer-generated designs and operation of water quality detention basins and pump stations.
