TO: MAYOR AND TOWN COUNCIL
FROM: GREG LARSON, TOWN MANAGER
SUBJECT: ARCHITECTURE AND SITE APPLICATION S-11-001. PROPERTY
LOCATION: 16161 SHORT ROAD. PROPERTY OWNER: JOHN AND
ELVIE SCOTT. APPLICANT: CHRIS SPALDING. APPELLANTS: ROBERT
AND LOIS MALLISON, DAVID CLARKE, AND DEBRA FETTERS.
CONSIDER AN APPEAL OF A PLANNING COMMISSION DECISION
APPROVING DEMOLITION OF A SINGLE FAMILY RESIDENCE AND
CONSTRUCTION OF A NEW SINGLE FAMILY RESIDENCE ON PROPERTY
ZONED R-1:20. APN 523-09-029.
STAFF REMARKS:
The following questions were raised by a Council member regarding onsite drainage in relation to
building footprints. Staff felt the responses would be helpful for all to understand.
1) Difference in drainage when considering a single vs. a two story residence:
The proposed two story design allows the impervious surface of the proposed residence to be
approximately 1,200 sq. ft. less than it would potentially be with all the proposed square feet in a
single story (a difference of 9% of the lot as a two story and 14% of the lot as a single story when
considering just the living floor area). With an increase in the house footprint, there will be an
increase in the total storm drainage peak flow along with the reduced pervious area. The ability
for the storm water to percolate into the ground would be less than optimal. In addition, it may
be difficult to provide the necessary drainage installations in appropriate locations on the
property with the larger footprint.

2) Difference in drainage with potential swimming pool and landscaping on applicant's lot:
A pool does not count towards impervious surface area according to State stormwater
regulations. A pool would act as a temporary storage area during a large storm, and any water
overflow would be directed to the sanitary sewer system and would not impact adjacent
properties. No impervious hardscape landscaping is proposed at this time with this application,
and the driveway incorporates permeable pavers.
