The City of Isleton is soliciting for qualifications from qualified consulting firms to develop a Storm Drain Master Plan for the City of Isleton. This statement of qualifications is to provide a background of the firm’s experience with preparing utility plans for a similar sized community and to provide information on your firm’s history and ability to prepare a Storm Drain Master Plan.  

The City of Isleton is a small city with an estimated 2022 population of 780, 222 single-family homes, 109 multifamily units, and 56 mobile homes (California Department of Finance [DOF] 2022) (see Figure 1).  Storm water drainage in the city consists of a traditional above ground curb and gutter collection system and some underground facilities covering approximately 250 acres. Much of the City street system has curb and gutter and some drop inlets installed with ultimate disposal to major drainage ditches south of town. There are also roadside ditches in various areas of the City. Where curb, gutter and drop inlets are missing, drainage occurs by overland flow to the lowest points along the street system and adjacent parcels.  Please see attached Request for Qualifications.
