Subject: Britts Mountain (SDP201200067) critical slope waiver request
The critical slope waiver request has been reviewed. The engineering analysis of the request follows:
Description of critical slope area and proposed disturbance:

site development for a tier II personal wireless service facility.
Areas
Acres
Total site
4.508 acres approximately
Critical slopes
3.338
74% of site
Critical slopes disturbed
0.24
7.2% of critical slopes
Exemptions to critical slopes waivers for driveways, roads and utilities without reasonable
alternative locations:
This disturbance is not exempt.
Compliance with Zoning Ordinance 18 -4.2:
"movement of soil and rock"
Proper slope construction, control of drainage, and vegetative stabilization will prevent any movement
of soil.
"excessive stormwater runoff'
Stormwater runoff will be maintained roughly as it is today in this area, as much of the work is along
an existing gravel driveway and old logging road. Additional vegetation will help off -set the proposed
impervious area.
"siltation"
Inspection and bonding by the County will ensure siltation control during construction. Proper
stabilization and maintenance will ensure long -term stability.
"loss of aesthetic resource"
This area is visible from the roads and houses in the neighborhood.
"septic effluent"
This neighborhood is not serviced by public sewer.
Based on the review above, there are no engineering concerns that prohibit the disturbance of the critical
slopes as shown.
