Date of Site Visit Meeting: September 25,2018
Zoning:The zoning designation for the site is Rural Residential 20(RR20).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.The setbacks are measured from structures above grade such as roof overhangs(roof gutters),and other structures/appurtenances,
including heat pumps etc.When the lot width is less than 100 feet,setbacks would equal 10%of the lot width.
An administrative variance can be applied for to get a reduction in the required setbacks(minimum of 5 feet for sides,minimum of 10 feet for front and'rear)if the lot meets certain criteria Other setbacks can
apply when critical areas are present,see below.
All setbacks are measured from the furthest projection of the structure(including roof eves and gutters).
Height limit per Mason County Code(MCC) 17.04.224.0 is 35 feet.
Shorelines: Shoreline Designation under the Mason County Shoreline Master Program(MCSMP)is Residential.Minimum structural setback is 11 5'per the MCSMP Table 17.50.110-A:Buffer and
dimensional standards for shoreline Development.However,the Mason County Resource Ordinance uses a"common line"provision per MCC 8.52.170(E)(3)(b),which applies in this case:
"Common Line"on Residential Lots.
The following are special provisions for buffers and setbacks for single family residential development on lots created prior to December 5, 1996,and which are located on saltwater or on a freshwater lake
twenty(20)acres or larger in size.
(i)Where existing residences are on both sides of and within 150 feet of the lot line of the subject lot,and no more than 200 feet from the shoreline OHWM,the setback on the subject lot is determined by an
imaginary common line drawn across the subject lot which connects the shore-side roof lines of the first adjacent existing residences.
(iii)The common line set back may be more or less than 115 feet from the OHWM,provided,however,that:
a. the buffer shall not be less than 20 feet in width from the OHWM and a minimum setback from the edge of the buffer is 15 feet;
b. If the resulting common line setback is less than the standard setback(shown in Table 8.52.170.C),a Common Line Mitigation Plan or a Habitat Management plan shall demonstrate that mitigation will
be provided to offset the potential impacts(resulting from the proposed development and use)to the buffer and resource.
A Common Line Mitigation Plan may be prepared by the property owner or his/her designee and shall meet the requirements in Appendix B,or a Habitat Management Plan shall be prepared by a qualified
habitat biologist and meet the requirements in subpart J.
Mitigation Manual.
Best management practices such as those in Appendix C shall also be implemented to limit impacts to the resource.
(iv) As used in this section,a"residence"refers to the principal dwelling/residential structure and does not include outbuildings or other structures.
