Santa Clara County Onsite Wastewater Ordinance Update
Document Type
NOP - Notice of Preparation of a Draft EIR

Code Update - N/A
Document Description
The County proposes to adopt a new ordinance that would update and replace existing County regulations governing individual onsite wastewater treatment and dispersal systems (Onsite Systems or OWTS). Onsite system regulations the County are currently codified in Division B11 of the Santa Clara County Code ("Ordinance"), most recently revised April 15, 2003. The proposed project is anticipated to remove some existing constraints to the development of existing parcels that depend on the use of OWTS for sewage disposal mainly through: (a) reduction in leachfield land area requirements; (b) the ability to utilize more advanced technologies (as compared with conventional septic systems) to overcome certain types of site constraints; and (c) the removal of minimum lot size limitations for use of OWTS in the Lexington Basin.
