Project#: SP12022-00153 for tax parcel 122295001002
Date of Site Visit:January 25, 2023
Zoning:The zoning designation for the site is Rural Residential 5 (11135). Standard setbacks for this zone
are a 25-foot front yard setback and a 20-foot setback for side and back yards. The front yard refers to
the lot line adjacent to the property access, including access easements.When the lot width is less than
100 feet,setbacks would equal 10%of the lot width.
If the lot meets certain criteria, an administrative variance may be submitted to request a reduction in
the required setbacks (minimum of 5 feet for sides, minimum of 10 feet for front and rear). Other
setbacks may apply when critical areas are present,see below.
The setbacks are measured from structures above grade such as roof overhangs (roof gutters), and
other structures/appurtenances, including heat pumps, etc.
The height limit per Mason County Code (MCC) 17.04.224.0 is 35 feet.
Geological/landslide hazards:The proposed project is located within 200' of slopes greater than 40%, or
a designated hazard area and therefore, a Geotechnical Report will be required to evaluate slope
stability per Mason County Code (MCC)8.52.140(E)(1). Category a.
The report must meet the requirements of the Mason County Resource Ordinance and be accompanied
by the Geotechnical Report Submittal Checklist.The report must also state that the hazards of any
landslide area can be overcome in such a manner as to prevent harm to property, public health,and
safety, and must also assure that the project will cause no significant environmental impact. See MCC
8.52.140(E)(5).A list of Geotechnical consultants is provided for your information, although you may
also choose other qualified professionals, not on this list. You can find additional information at this
