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:
Building permits will require an E &SC "in lieu of' grading permit agreement promising that the owner will
follow the State requirements for erosion and sediment control.
"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 reduced in this area, as the slopes will be eliminated.
"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. Some of the slopes were created with
the road construction.
"septic effluent"
This neighborhood is serviced by public sewer.
Based on the review above, engineering recommends an over -lot grading plan to protect the adjacent property
owners' pond.
