October 30,1998 <br /> The Orange Water and Sewer Authority(OWASA)report entitled"Final Recommendations for . <br /> Protecting the Cane Creek Water Supply"was referred to Planning staff to 1)evaluate the <br /> watershed study,and 2)prepare a staff report with applicable recommendations,prior to the <br /> development of any proposed ordinance amendments: <br /> Accordingly,this summer,planning staff members formed the Cane Creek Analysis Team <br /> (CCAT)to evaluate the implications of the Cane Creek Reservoir Watershed Study and final <br /> OWASA recommendations.Because of the cost and time required to quantify impacts, and the <br /> unknown cost-effectiveness of such research,assessment of the watershed study and OWASA <br /> recommendations impacts was largely of a qualitative nature.At this point,staff are able to <br /> Provide preliminary recommendations to the Board of Commissioners.Following:additional <br /> input,.staff will-prepare a final recommendation for the November 23, 1998 public hearing. <br /> Staff Analysis. <br /> Preliminary-analysis of the watershed study and OWASA recommendations reveals that.ensuring <br /> adequate and reliable long-term protection of the water quality of Cane Creek Reservoir . <br /> necessitates a reduction in-the pattern,intensity and/or amount of future development activity in <br /> the watershed. Such a reduction can only be accomplished with.certainty through land use <br /> controls that cause development to occur in either large4ot or cluster configurations.Based on <br /> staff's analysis,there appear to be three watershed management options that would accomplish <br /> the needed long-term water quality protection.Each offers potential benefits and drawbacks. <br /> Option 1:Mandatory Flexible Developmentl Large Lot . <br /> Current two-acre zoning along with mandatory flexible development(33%open space) <br /> outside of the watershed critical area.In the critical area;five-acre lot zoning with up to <br /> five lots as small as two acres for lots of record..OWASA 20-year plan for land acquisition <br /> resulting in 1,266 acres. <br /> Option 2: Creative Open-Space Development("Open-Space"or "Cluster') <br /> Current two-acre zoning along with mandatory"Creative Open-Space Design"(50%open <br /> space with one acre minimum lot size).
