Document Description
The Project is proposed to replace the existing wastewater system underlying the vacant lot at 21 Calle del Onda. The existing system was installed in 1985 and has not been used since a fire burned down the single-family residence served by the system in the mid-1980s. The Applicant proposes to replace the decades-old system with a 2,000-gallon septic tank, 2,000-gallon dual compartment sump tank, and sub-grade concrete retaining wall. The proposed septic tank will be installed following issuance of a building permit by the County of Marin. A single-family residence with no more than 1,400 square feet (sq ft) of habitable space may eventually be constructed on the site, but is not proposed at this time. The details of such development would be determined at a later date.
