(SE202000006) — Critical Slopes Impact Review
The critical slope waiver request has been reviewed. The applicant provided field -certified topographic
data, which is more accurate than County GIS data. The engineering analysis of the request follows:
Description of critical slope area and proposed disturbance:
The critical slopes proposed to be impacted were created during the construction of Interstate 64 and the
construction of an access road through the parcel. The land cover is currently wooded, except for the
existing access road. The applicant proposes critical slope impacts for an access road to the proposed
tower.

Exemptions to critical slopes waivers for driveways, roads and utilities without reasonable
alternative locations: The proposed disturbance is not exempt as defined in Section 4.2.6.
Compliance with Zoning Ordinance 18-4.2:
"movement of soil and rock"
The existing slope is stabilized. Proper slope grading, control of drainage, ESC measures, and
vegetative stabilization will minimize movement of soil.
"excessive stormwater runoff'
The proposed land cover (gravel) is semi -pervious and will allow stormwater to infiltrate so no
additional post -development runoff is expected.
"siltation"
The disturbed area is below the County land disturbance threshold for permitting but the applicant
stated ESC measures will be used throughout construction. Permanent stabilization and maintenance
will ensure long term stability.
"loss of aesthetic resource"
This area will be screened from view by the existing trees.
"septic effluent"
There are no septic systems proposed with this unmanned facility.
Based on the review above, there are no engineering concerns which prohibit the disturbance of the
critical slopes as proposed.
