2.4 PROJECTFEATURESMidPenproposesthedevelopmentof71affordablehousingunitsontheprojectsite,consistingof18two-storybuildingsholding2-4unitseach(seeFigure3).Theprojectwouldprovideamixtureof1,2,and3-bedroomunits,includingacombinationoftwo-storytownhousesandADA-accessiblesingle-levelflats.Inadditiontothehousingunits,thedevelopmentwillincludeanapproximately3,200squarefootcommunitybuildingthatwillincludethegeneraloffice,themanager’soffice,acommunityroom,kitchen,computerroom,laundry,andmaintenanceandstorageareas.Theprojectplanalsoincludesseveraloutdooramenities,including:

• Landscaping(seemorebelow);• Acommunitygarden;• Achildren’splayarea;• Anupperandalowergreen;• BBQareas;and• Apublicwalkingtrailthroughaportionofthesite.

Alloftheunits,exceptforthemanager’sapartment,willbeaffordabletohouseholdsearningupto80percentoftheAreaMedianIncome(AMI).ItisexpectedthattheCypressPointprojectwillprovidehousingforapproximately213people,includingadultsandchildren.Thedensityis6.5unitsperacre,significantlybelowthemaximumdensityallowedbythecurrentGeneralPlandesignation,zoning,andLCPdesignation.MidPenhasalsoclusteredthedevelopmentsoastoretaintheforestedopenspaceonthenorthernportionofthesite.Totheextentfeasible,MidPenwillretainthevegetationadjacenttoCarlosStreetandSierraStreetalongtheperimeterofthesiteoraddvegetationtoshelterthesitevisuallyfromneighbors.Altogether,MidPenproposestoleaveapproximatelyhalfofthesiteundeveloped.

Becausethisprojectisintendedtocontributetoimprovingthejobs-housingbalanceandjobs-housingfitincoastalSanMateoCounty,preferenceforhousingwillbegiventopeoplewhocurrentlyliveorworkintheregion.
