How does this policy effect Waiver Prohibition Areas?
There are a number of communities subject to waiver prohibitions, with differing restrictions and requirements. However, none of the communities are identified as RWQCB Basin Plan Waiver Prohibition Areas (Section VII Policy on the Control of Water Quality With Respect to On-Site Waste Treatment and Disposal Practices). The following communities are identified as County Waiver Prohibition Areas:
Camp Meeker, Carmet, Rancho del Paradiso, Salmon Creek, Sereno del Mar, Jenner, Monte Rio, Happy Acres, Penngrove/South Cotati, West Petaluma, Russian River Meadows, South Wright Road Area, Thomas Larkin Woods, Westvue Meadows.
In general, Permit Sonoma shall not process any waiver requests for new construction on vacant land or to existing structures in Waiver Prohibition Areas that would result in an increase in flow (some of the Waiver Prohibition Areas address only a specific concern and are not a blanket waiver prohibition). All modifications to existing structures shall comply with the Permit Sonoma Remodel Policy. The Remodel Policy applies only to existing structures (defined as recent and continuous service previous two years) with no increase in flow. Under the Reutilization and Remodel Policies, justification for issuance of a waiver is required to meet the re-defined Class I standard for systems that service existing structures. Justification for waivers that are approved by Permit Sonoma for Major Additions and/or Rebuilds of existing structures are possible in County Waiver Prohibition Areas, provided there is no increase in the strength or volume of wastewater generated.
If I already have a building permit and I want to add to the scope of work, will I be subject to the new policy or the old policy?
The revised project will be subject to the new policy.
Example: Under the old policy the percentage of lineal footage of altered wall for a dwelling with a Class III system was 35%. A revised project is proposed to include an additional remodel subject to a B-BLD or <500 square foot addition as well. Under the old policy an office clearance was given based upon a microfilm record of a 1976 permitted septic system and the percentage of remodel was limited to 35%. Under the new policy, a findings report or field clearance would be required for this new remodel or minor addition (Class III system >20 years old).
Is Planning Clearance required for a Building Permit under this policy?
A Planning Clearance is not required for an interior remodel. However, Planning Clearance is required for all rebuilds and additions due to the fact that these rebuild and/or additions may impact required setbacks to property lines, scenic or riparian corridors.
Is the square footage measured by using the interior or exterior dimensions for new additions?
Use the interior dimensions for the determination of square footage of new additions of habitable space. Note that additions may not encroach upon potential reserve expansion area.
Are walls that are removed and replaced to accommodate an Addition counted as walls removed and replaced as a percentage of a Rebuild?
Yes. Addition(s) that result in the removal and replacement of 50% or more of the exterior lineal footage of existing walls count as a percentage of Rebuild.
How does this Policy relate to the Reutilization Policy?
The Reutilization Policy remains in effect. The Remodel Policy is intended to clarify the interpretation and implementation of the Reutilization Policy.
