RE: Dominion Office Park, Phase 1, Major Site Plan Amendment
Request for Critical Slopes Waiver
To whom it may concern:
This letter is to request a waiver from the requirements of Section 4.2 of the Zoning
Ordinance. The attached site plan shows that there are areas with 25% or greater
slopes that will have to be disturbed as part of this road project.
The total area of existing critical slopes on TMP 78-15C2 is 18,252 SF.
The total area of critical slopes that will be disturbed for the parking lot expansion and
associated stormwater management facilities is 1,624 (9 percent).
Description of Parcel Area Total Critical Total Critical % of Critical
Areas slopes on slopes slopes

TMP 78-15C2 47,436.84 SF 18,252 SF 1,624 SF 9%
(1.089 acres) (0.42 acres) (0.03728acres)
Below, each of the concerns of Zoning Ordinance section 18-4.2 is addressed.
1. "movement of soil and rock": We will provide an erosion and sediment
control plan for controlling the movement of soil and rock involved with the
construction proposed in the critical slopes.

2 "excessive stormwater run-off': We will provided information concerning how
the stormwater runoff will be controlled by the drainage and stormwater
management plan proposed for this project.
3. "siltation of natural and man-made bodies of water": Inspection and bonding
by the County will ensure siltation control during construction. Proper
stabilization and maintenance will ensure long term stability.
4. "loss of aesthetic resource": The existing critical slopes proposed for
disturbance are delineated on the Open Space Plan Composite Map for
Neighborhood 3 and are located within a Major or Locally Important Stream
Valley — the Rivanna River. River and stream valleys are designated as
important resources that are often associated with critical slopes. Although
disturbance of these slopes is minimal it will be further mitigated by erosion
control measures minimizing the chance of erosion on the downhill slopes
approaching the flood plain and river. Also, a tree conservation measures and
the applicant's contribution to The Greenway by means of a dedicated
easement further protect this important aesthetic resource.
5. "septic effluent": No septic systems or drainfields are proposed in this
project. This project will be served by the public sanitary sewer system.
This site does not drain into a waterway that is a public drinking water supply for
Albemarle County. The most southern portion of TMP 78-15C2 is shown within the 100-
year flood plain area according to FEMA Map 51003CO287D, dated 04 February 2005.
The reasons given above demonstrate that the grading of critical slopes on this project
will not be detrimental to the health, safety, and/or welfare of the public.
Please call me if you have any questions or concerns.
Sincerely,
Z:://;////
