PETITION:
PROJECT: SP 2006-1 Biscuit Run Stream Crossing (Southern)
PROPOSED: The applicant proposes to install a span crossing within the floodplain to serve the
southern portion of the proposed Biscuit Run Community (ZMA 2005-17).

SECTION: Section 30.3.05.2.1(2) of the Zoning ordinance
COMPREHENSIVE PLAN LAND USE/DENSITY: Neighborhood Density Residential - residential (3-6
units/acre) and supporting uses such as religious institutions and schools and other small-scale non-

ENTRANCE CORRIDOR: Yes_X_No Location: Overall project is located between the east
side of Old Lynchburg Road and the west side of Route 20; adjacent and to the south of the Mill Creek
subdivision, adjacent and to the west of the intersection of Avon Street, Extended and Route 20. This
crossing is located at the southern end of the project, approximately 0.38 mile west of Route 20
(Scottsville Road)
TAX MAP/PARCEL: 90-6D
MAGISTERIAL DISTRICT: Scottsville
CHARACTER OF THE AREA: The site is undeveloped and wooded.
SPECIFICS OF THE PROPOSAL: A special use permit is being requested for fill in the floodplain to
install a new stream crossing of an unnamed perennial tributary to Biscuit Run. The new stream
crossing will serve the southern portion of the Biscuit Run Community, adjacent to the proposed district
park area. The new crossing will utilize a bridge span to minimize impacts to the stream channel (see
Attachment D for photo of stream crossing area).
The 2005 FEMA Flood Study and Maps included this stream in the "detailed study" and the Base Flood
Elevations were determined. According to this study the 100 -year flood elevation at the location of the
crossing is base flood elevation 430.6. With the addition of the new span crossing and fill the new base
flood elevation will be 431.0. This increase of 0.40 foot is not significant.
The new crossing will be located within the vegetative stream buffer for the unnamed perennial tributary
to Biscuit Run required by Section 17-317 of the Water Protection Ordinance. The applicant has
proposed to mitigate these impacts as required under Section of 17-322 of the Water Protection
Ordinance through restoration of riparian areas along an upstream segment of this tributary, where
County staff identified the need for buffer restoration.
PLANNING AND ZONING HISTORY:
On September 12, 2007 the Board of Supervisors approved a rezoning request for the proposed Biscuit
Run Community. The concept plan associated with this rezoning illustrates this crossing of an
unnamed perennial tributary to Biscuit Run as the southern of three crossings to serve the proposed
Biscuit Run development (see Figure 1 — crossing locations circled in red).
Conformity with the Comprehensive Plan:
The Open Space and Critical Resources Plan, a component of the Comprehensive Plan, identifies
shows many important resources located on the entire Biscuit Run property. In addition, the
Stormwater Master Plan, also a component of the Comprehensive Plan, identifies this portion of stream
as "community and private use/trails" which is the second highest County stream ranking, indicating
that the area has some habitat and natural aesthetic values. The expectation by the Open Space Plan
and the Stormwater Master Plan is that the stream corridor should be managed to accommodate
2
development objectives while also preserving habitat and water quality. By utilizing a span bridge
crossing, impacts to the stream channel and adjacent wetlands will be minimized.

STAFF COMMENT:
Staff will address each provision of Section 31.2.4.1 of the Zoning Ordinance
to
31.2.4.1: Special Use Permits provided for in this ordinance may be issued upon a finding by the
Board of Supervisors that such use will not be of substantial detriment to adjacent property,
The County Engineer and engineering staff have reviewed the applicant's proposal, and concur with the
applicant's conclusion that the installation of the new span crossing will not result in a significant
increase in the 100 -year flood elevation and will not detrimentally affect adjacent properties, existing
development, or planned development.
that the character of the district will not be changed thereby and
The proposed stream crossing is interior to the project site and is not expected to be visible from the
entrance corridor.
that such use will be in harmony with the purpose and intent of this ordinance,
The Flood Hazard zoning has the purpose and intent of restricting development in the floodplain which
may result in danger to life and property, public costs for flood control measures, public costs for rescue
and relief efforts, soil erosion and sedimentation, pollution of water resources, and general degradation
of the natural and man-made environment.

The span crossing's minimal impact to the 100 -year flood elevation is in harmony with the Flood Hazard
overlay zoning.
with uses permitted by right in the district,
The installation of a stream crossing to provide access to a planned development would appear to be in
harmony with the other uses permitted by right in the district.
with the additional regulations provided in section 5.0 of this ordinance,
There are no supplementary regulations relating to the placement of fill in the floodplain for a stream
crossing in Section 5.0 of the Zoning Ordinance.
and with the public health, safety and general welfare.
The installation of a new span crossing will not significantly raise the 100 -year flood elevation and will
not detrimentally affect adjacent properties.
SUMMARY:
Staff has identified the following factors which are favorable to this request:
1. No impact to neighboring properties is expected as a result of this special use permit
2. No significant increase in flood levels will result from installation of the new crossing.
Staff has not identified any factors which are unfavorable to this request.
RECOMMENDED ACTION:
Staff recommends approval of the request with the following conditions:
1. The applicant must obtain a map revision, letter of revision, or letter of amendment as
required from the Federal Emergency Management Agency (FEMA) and copy the County
Engineer on all correspondence.
2. Army Corp of Engineers, Virginia Department of Environmental Quality, and other necessary
state and federal agency approvals must be obtained prior to issuance of grading permits for
construction of the new stream crossing and approaches.
3. County approval of road and bridge plans for the crossing to be in accord with the
application plan, as determined by the County Engineer.
4. County approval of a grading and an erosion and sediment control plan prior to the issuance
of a grading permit for construction of the new stream crossing and approaches.
5. County approval of a stream buffer mitigation plan prior to the issuance of a grading permit
for construction of the new stream crossing and approaches.
6. Grading within floodplain shall be confined to the minimum necessary to construct the bridge.
Changes in final design of the bridge, such as use of a longer span, are acceptable if the
changes reduce impacts to the floodplain, in the opinion of the County Engineer.
