<br />..:5: / e-z <br /> <br />Since 1995, the City of Redwood City has purchased 0.64 millions of gallonslday <br />(MGD) of a total of 2.685 MGD stage II maximum allotment from SBSA. Based on the <br />water demand projection in the Urban Water Management Plan, by the year 2020, the <br />projected water demand may increase about 1,867 Acre Feet/year, which equates to <br />about 1.67 MGD. As a conservative estimate, the sewage demand is assumed to be <br />about 95% of the water demand, which equals about 1.58 MGD. With the current <br />available capacity of about 2.045 MGD(2.685 MGD - 0.64 MGD), by the year 2020, <br />Redwood City's remaining allotment is projected to be 0.465 MGD (2.045 MGD - 1.58 <br />MGD). <br /> <br />The County of San Mateo Public Works Services has identified nine parcels remaining <br />in unincorporated County and in Redwood City's Sphere of Influence that may require <br />sewer service from the City at some time in the future. One parcel is estimated to <br />require about 270 gallonslday of sewage capacity. The nine parcels combined will <br />demand about 0.00243 MGD, which can be considered as minimal compared to the <br />available capacity. <br /> <br />Alternative <br />Do not approve the sewer service area extension, and reserve Redwood City's sewer <br />capacity allocation for future use. The nine parcels will remain on septic system, or <br />seek sewer service from other agencies. <br /> <br />Fiscal Impacts <br />There are no significant fiscal impacts to the City. <br /> <br />\ r-:=. ;: r <br /> <br />Joel Patterson <br />Community Development Services Director <br /> <br /> <br />~Æ: <br /> <br />Grace Le, P.E. <br />Associate Civil Engineer <br /> <br />GL:ss <br />s/Iibrary/reports/grace/approval_sewer service area extension <br /> <br />Page 2 of 2 <br />
