Sky Mesa Commons Subdivision No. 5
Storm Water Drainage Report
Page 2
Site Location
The project site is located approximately 700 feet west of S. Eagle Road and 1,000 feet
south of E. Taconic Drive in the City of Meridian, in the SE 1/4 of Section 32, Township 3
North, Range 1 East, Boise meridian.
Existing Site Characteristics
The approximately 4.0 acre project site is partially developed as part of the adjacent
subdivision to the north. The area has been rough graded and slopes down-gradient to
the north at slopes less than 2%.
Proposed Site Improvements
The proposed improvements include the construction of 13 residential lots, 1 common lot,
and associated streets, sidewalks, and infrastructure.
Drainage Design Concept
The project consists of 2 catchment, labeled H and L.
Stormwater collected in catchment H is directed toward a storm drain system designed
and installed as part of the subdivision phase to the west. See the included catchment
map for Sky Mesa Highlands.
Stormwater collected in catchment L is directed to catchments 3 and 4 as shown in the
included Sky Mesa Commons Subdivision No. 1 Site Drainage Plan.
No storm drain collection systems are designed as part of this project.
