RE: Agnor Hurt Elementary School Renovations and Additions—Critical Slopes Waiver Request
To Whom It May Concern:
Albemarle County Public Schools is submitting this waiver of Chapter 18, Section 4.2 of the
Albemarle County Zoning Ordinance to allow disturbance of critical slopes to allow the building
and site additions at Agnor Hurt Elementary School. The site is located on tax map parcel 04500-
00-00-095A0.
The overall project includes building additions and renovations, as well as a new bus loop and car
loop. Under current conditions buses and cars use the same road to access the school for
morning drop-offs and evening pick-ups. The proposed site will separate the buses from the cars,
improving the safety of the site. Additionally, site grading, stormwater management, and other
infrastructure improvements are also being proposed to support the building and site additions.
The Major Site Plan Amendment that has been filed specifies the location of critical slopes and
those that are proposed to be disturbed.
Agnor Hurt Elementary School Critical Slope Site Characteristics
Total Area of Site 19.53 acres
Total Area of Existing Natural Critical Slopes 0.95 acres
Total Area of Man Made Critical Slopes 2.55 acres
Total Area of Critical Slopes 3.50 acres
Total Area of Disturbed Existing Natural Critical Slopes 0.00 acres
Total Area of Disturbed Man Made Critical Slopes 0.55 acres
Total Area of Disturbed Critical Slopes 0.55 acres
Per Section 4.2 of Chapter 18 of the zoning ordinance the five health, safety and welfare provisions
will be addressed as follow:
I. Rapid and/or large scale movement of soil and rock — On site construction will require
that earthwork be done to grade a pad for the building addition on the northeast side of the
site, as well as for the proposed bus loop. The erosion and sediment control plan will stabilize
these areas by having them drain to a sediment basin. Additionally, blanket matting,
temporary seeding, and permanent seeding measures will be used. Any areas that do not
drain to the sediment basin, will be stabilized and protected from the risk of large scale
movement of soil and rock by silt fence.
2. Excessive Stormwater Runoff— The increased runoff from any site improvements will be
controlled by an underground detention system. Additionally, the stormwater will be treated
to meet water quality requirements. Excessive stormwater runoff will not occur as the
detention system will reduce the rate of runoff to the existing conditions.
3. Siltation of natural and man-made bodies of water — During construction Erosion and
Sediment control measures will control any possible downstream siltation from occurring.
Once the site has been stabilized the underground detention system and BMP treatment
facility (cartridge system) will prevent any silt discharge downstream in the natural drainage
path or onto adjacent properties.
4. Loss of aesthetic resource—All site improvements will be subject to meeting the County's
Zoning Ordinance for landscaping. Tree clearing will be kept to a minimum to protect the
natural resources while expanding the school's classroom space and providing better site
access for both cars and buses.
5. Greater travel distance of septic effluent—Septic effluent issues are not applicable to this
site as the addition will be making use of the existing sanitary sewer facility and will be served
by public water.
In accordance with Section 4.2.5 of Chapter 18 of the Zoning Ordinance, we request that a waiver
be granted to remove restrictions regarding the disturbance of critical slopes as part of the Agnor
Hurt Elementary School Renovations and Additions plan for the reason the improvements to the
site will allow the school to be expanded, better serving the community and its students, and
increase the overall safety of the site by separating car and bus traffic.
