lines (15 feet on either side of the line), an additional 15 feet of additional easement are J required. Furthermore, OWASA is seeking an additional 15 feet of temporary construction easement. During periods of heavy rainfall, the existing Booker Creek sanitary sewer interceptor has historically had a problem with large amounts of stormwater infiltrating into the line. This infiltrated stormwater, when combined with sanitary sewerage flow, has exceeded the hydraulic carrying capacity of the existing line.. Consequently, during these periods of significant rainfall, stormwater and sewerage from the Booker Creek interceptor has spilled out of manholes in the low areas along Booker Creek. The replacement of the Booker Creek interceptor is intended to eliminate the inflow of stormwater into the system, reducing total flow and eliminating hydraulic overload. and sewerage spills. The logical route for the new Booker Creek interceptor is both parallel and close to the existing line. Accordingly,. OWASA has very little in the way of alternatives to following the route of the existing line across County property. Given that the County property is: 1) in a very low area which is not a particularly practicable location for buildings or other structures; .and 2) already impacted significantly by the existing sewer easement, it does not appear that the requested easement will significantly affect either the potential use or value of the property. FINANCIAL IMPACT: None RECOMMENDATION(S): The Manager, in recognition that the proposed easement does serve an important public purpose. by helping correct an existing and undesirable situation involving sanitary sewer spills along Booker Creek, recommends that the BOCC direct .staff to prepare the documents necessary to assign the requested easement to OWASA under the signature of the Chair.
