Subject: Hunter's Way Major (SDP201800040) — 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 SR 250 and Hunters
Way. The land cover is currently managed turf. The applicant proposes critical slope impacts for a drive
lane around the proposed new retail building and to avoid the need for retaining walls.
Areas
Acres
Total site
1.46 acres (63,612 sf)
Critical slopes
14,485 sf
22.8% of total site
Critical slopes disturbed
2,448 sf
3.8% of total site
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 with turf. Proper slope grading, control of drainage, ESC measures, and
vegetative stabilization will minimize movement of soil.
"excessive stormwater runoff'
The proposed land cover (turf) is the same as the existing land cover so no additional post -
development runoff is expected.
"siltation"
This project will require VSMP permitting and bonding. Inspections and bonding by the County will
ensure siltation control during construction. Permanent stabilization and maintenance will ensure long
term stability.
"loss of aesthetic resource"
This area is visible from Route 250 but is currently managed turf The area will remain managed turf.
"septic effluent"
The proposed buildings will connect to a private sewer septic system more than 350 feet from the
proposed disturbance. Also, fill is proposed on the critical slopes versus cut, which would reduce
potential septic effluent discharges.
Based on the review above, there are no engineering concerns which prohibit the disturbance of the critical
slopes as proposed.
