Subject: UVA Tier III Tower CV825 Cedar Hill (SP201200016) 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:
This is a proposed wireless telecommunications facility and includes a critical slope area. The applicant is
proposing to include a monopole structure, two equipment cabinet platforms, a future 45 square foot
concrete equipment slab within a 600 square foot gravel compound with a proposed retaining wall.

Total project site

Critical slopes

100% 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 should prevent any
movement of soil.
"excessive stormwater runoff'
The proposed telecommunication facility's surface will be pervious, consisting of a layer of gravel
over a meshed layer of geo- synthetic fibers. This project is unlikely to cause excessive stormwater
runoff.
"siltation"
Proper stabilization and maintenance can help long term stability. Measures proposed include soil
stabilization blankets and matting at the existing steep slopes and silt fence and construction entrance
during construction.
"loss of aesthetic resource"
Eighteen trees are proposed to be removed as part of this project. This should cause a minimal impact
to loss of aesthetic resource in the rural area of the county.
"septic effluent"
This project does not propose any sanitary facilities.
Based on the review above, engineering recommends approval of this critical slopes disturbance waiver
request.
