Retaining walls have the potential to create hazards to property or persons. Depending on the specific nature of the improvements proposed, a Grading Permit may be required to ensure safety and prevent property damage.
A Grading Permit is required under the following circumstances:
- If the wall is located within five feet of the property line or the city’s right-of-way line. (Grading Ordinance)
- If the wall height is four feet or greater. (Grading Ordinance)
- If the wall is retaining a slope that is steeper than two horizontal to one vertical (2:1). (Grading Ordinance)
- If the wall impacts any open space or environmentally sensitive areas designated in the General Plan (Grading Ordinance)
- If the wall will impact any waterway or wetland, stream, river, channel, pond, lake, marsh, bog, lagoon, vernal pool or riparian habitat. (Grading Ordinance)
- If the wall is to be constructed in any floodway or floodplain (Grading Ordinance)
- If the wall is to be constructed in any officially mapped zone of high geologic risk (Zone “C” and “D”) as defined by the geotechnical/seismic study for the General Plan. (Grading Ordinance)
- If the wall is to be constructed in the hillside overlay district. (applies to any HL, R-1 & R-1A zoning designation) (Grading Ordinance)
- If the wall is constructed in any other sensitive area such as archaeological sites, historical sites or burial grounds. (Grading Ordinance)
If no Grading Permit is required a Building Permit from the Building Division will be required under the following circumstances:
- If the wall is supporting a surcharge of any kind. A three foot wall installed within three foot of a structure such as a house will have a surcharge from that structure. A three foot wall within three feet of a driveway will have a surcharge from the vehicles that park on the driveway. (Uniform Building Code)
- If the wall is used to impound flammable liquids. (Uniform Building Code)
