Article IV. Permits and Inspections

8.60.140 Findings and declaration of intent.

The City of Poway has an overriding interest in planning and regulating the use of property within the City. Implicit in any plan or regulation is the City’s interest in maintaining the quality of life and the character of the City’s neighborhoods. Without adequate facilities for sewage disposal, sections of the City can quickly deteriorate, with tragic consequences to social, environmental and economic values.

A concentration of individual structures in certain areas of the City disposing of sewage into septic systems will cause such areas of the City to deteriorate and result in a threat to public health, safety and welfare. It is the City’s intent to protect and promote the health, safety and general welfare of the community by instituting a comprehensive ordinance for the issuance of building permits for the construction of any structure which may use for the disposal of sewage a septic system. It is further the intent of the City to assure the compatibility between the proposed structure or facilities and the particular site and other existing and potential uses within the general area.

Without the additional requirements imposed in PMC 8.60.141, the building of additional structures using septic systems constitutes a current and immediate threat to the public health, safety and welfare of the community. (Ord. 160, 1985)

8.60.141 Permit required to construct septic tank.

No septic tank, settling tank, seepage pit, cesspool, subsurface tile line system, or any other subsurface sewage disposal unit or system, or any part thereof, shall be installed, constructed, reconstructed, repaired in any manner, or added to, in the City unless there is in effect a valid permit therefor issued by the Director of Public Services meeting all of the following requirements:

A. The Director of Public Services shall review and approve all septic system applications prior to submittal to the San Diego Health Department.

B. No septic system shall be installed on a parcel of land less than one acre in size, unless the Director of Public Services determines that the parcel cannot be economically served by City sewers and is in an area that has not experienced septic system failures in the past.

C. No septic system shall be installed within 200 feet of an intermittent stream unless the entire system, including leach lines, is a minimum of 10 vertical feet above the high water line. This requirement may be modified to meet the requirements of the San Diego County Health Department. (Ord. 655 § 2, 2007; Ord. 180 § 1, 1985; Ord. 160, 1985)
