OPM #1— Further Investigate Potential Use of Groundwater Based on the study Feasibility of Supplemental Groundwater Resources Development, Redwood City, Californiq prepazed by Todd Engineers and dated Ma� ch 2003, use of groundwater appeazs to be feasible and cost-effecrive. However, the City needs to drill one or more test wells in order to verify costs and the amount and quality of water provided. Drilling the test wells and analyzing data would take several months and cost approximately $100,000 per well. Thus, it was not possible to produce a quantifiable proposal for groundwater use by the Task Force deadline. The Todd Engineers study indicated a network of wells could recover between 500 and 1,000 AF/Y of op table water and would cost between $1,OOQ000 and $2,000,000 per production well, including other required equipment, engineering, and permitting. Data developed by City staff for the Task Force indicated that one production well for ircieation at Red Morton Park would cost approximately $25Q000, including other required equipment, engineering, and permitting (see Attachment 5). Not including the playing fields (which will have synthetic turf under Alternative TF), Red Morton Pazk has an inigation water demand of approximately 47 AF/Y. The Task Force strongly recommends that the City, at the earliest opportunity, begin exploratory well work, to determine feasibility and costs for using goundwater to irrigate large sites (e.g., Red Morton Park) and possibly as a supplementary source of potable water. The Task Force understands that certain prepazatory work, including exploring permitting requirements and conducting an environmental site assessment for potential well sites, needs to be performed prior to impiementing an exploratory well program. The Task Force believes it would be highly desirable to know the feasibility of using groundwater prior to the expiration of the existing Master Water Sales Contract with the San Francisco Public Utilities Commission ("SFPUC") on June 3Q 2009. 3.2.2. OPM #2 — Consider a Commercial Toilet Replacement Program � The City currently offers financial incentives to replace (a) toilets in single-family units, (b) toilets i� multi-family units, (c) clothes washers in single-family units, and (d) multi-family and commercial clothes washers with more water-efficient devices. However, the City does not Page 9 of 12
