Description of Project:
This project includes redevelopment of two single-family residential parcels. The proposed use is a maximum of 85 dwelling
units, for a density of 24 dwelling units per acre. The property is adjacent to a church, which would be considered a
low -volume commercial entrance and would require commercial entrance spacing standards.

SECTION 1
PROJECT NARRATIVE
Victorian Properties I1, LLC is the owner of tax map parcel 09000-00-00-035DO and James R. Moss is the owner of tax map
parcel 09000-00-00-035H0; Victorian Properties 11, LLC is the applicant (the "applicant") for a zoning map amendment
application known as 1805 Avon Street Extended, which pertains to tax map parcels 09000-00-00-035DO and 09000-00-00-
035HO (collectively, the "property'). The applicant seeks to rezone the 3.627-acre property from R-1 Residential to Planned
Residential Development. Currently, each of the parcels has an existing single-family residence and if approved, this rezoning
would allow 83 units to be developed. TMP 90-35D has an existing full access driveway off of Avon Street Extended, while
TMP 90-35H shares driveway access with TMP 90-35A, which has full access onto Avon Street Extended. TMP 90-35H
additionally has access on private streets Avinity Loop and Avinity Drive onto Avon Street Extended. Upon consolidating
the two parcels into one property, the access easements through TMP 90-35A and through the Avinity subdivision would
be abandoned and access would only be provided on Avon Street Extended. The property is adjacent to Church of God
Southside, whose use lends itself to be designated as a commercial entrance. Due to this designation, any proposed entrance
on 1805 Avon Street Extended would not meet Virginia Department of Transportation (VDOT) spacing standards; as a
property with only 126' of frontage on Avon Street Extended, siting the entrance to meet entrance spacing standards is not
possible.
This report will analyze the spacing
between entrances on Avon Street
Extended (Section 2), anticipated trips
through the entrances (Section 3);
and whether there is a need to install
turn tapers or turn lanes (Section
4). The following analyses indicate
that substandard entrance spacing
is not detrimental to ensuring safe
and adequate movements for 1805
Avon Street Ext. and Church of God
Southside, as the circumstances of this
proposal differ from typical mid- or
high -volume commercial entrances
that serve daily traffic needs.
SHIMP ENGINEERING, P.C.
SECTION 2
ENTRANCE SPACING
Route 742 Avon Street Extended is a 45-mph collector road. With the presence of Church of God Southside on TMP 90-35B
and Reynovia Drive immediately across from the church, spacing of an unsignalized intersection and a full access entrance
is 335, according to VDOT Appendix F Minimum Spacing Standards for Commercial Entrances (Table 2-2). The existing
entrance to the property is 132' from the Church of God Southside entrance and Reynovia Drive, serving one single-family
residence. The entrance is proposed to move approximately 47' towards the northern property line, such that the proposed
entrance would be 179' from the Church of God Southside's entrance. Due to the narrow shape of the parcel, it is not possible
for the entrance to achieve a spacing of 335' as the proposed entrance is positioned as far north as possible on the property.

SECTION 3
TRIP GENERATION
Entrance spacing between Church of God Southside and the proposed multifamily development does not meet VDOT
minimum spacing standards for commercial entrances, however, the nature of trips generated by religious institutions are
dissimilar to other commercial uses that would necessitate appropriate entrance spacing. Furthermore, peak hour timeframes
differ between that of a church and a multifamily neighborhood. The following trip generation was provided by ITE Trip
Generation, loth Edition. A 3,200 square foot church could generate one trip during the weekday morning peak hour and
two trips during the weekday evening peak hour. Due to the very low volume of weekday trips of the church and overall low
trips generated by the proposed multifamily units, there is no anticipation of conflicts to occur between these two entrances
that do not meet minimum entrance spacing.

SECTION 4
TURN LANE WARRANT ANALYSIS
Right and left turn lane warrant analyses are provided to indicate low volume of peak hour trips for the proposed multifamily
development. Right and left turn lanes are not required, indicating minimal conflicts between new trips and existing
background traffic on Avon Street Extended. As the new peak hour trips would not require additional infrastructure for safe
and adequate movement on Avon Street Extended, in addition to the existing one to two peak hour trips generated by the
church, entrance spacing of 179' would not diminish public access and safety on Avon Street Extended; because turn tapers
and turn lanes are not required by the proposed use, minimum entrance spacing would not be needed to minimize conflicts
between turn tapers, turn lanes, and the existing commercial entrance of the church. The following 2020 traffic data specific
to this portion of Avon Street Extended is provided by EPR, P.C.

PHV - Peak Hour Volume (also Design Hourly Volume equivalent)
Adjustment for Right Turns
For posted speeds at or under 45 mph, PHV right turns > 40, and
PHV total < 300.
Adjusted right turns = PHV Right Turns - 20
If PHV is not known use formula: PHV = ADT x K x D
K = the percent of AADT occurring in the peak hour
D = the percent of traffic in the peak direction of flow
Note: An average of 11 % for K x D will suffice.
When right turn facilities are warranted, see Figure 3-1 for design criteria.

SECTION 5
CONCLUSION
1805 Avon Street is a property designated as "Urban Density Residential' by Albemarle County. Urban Density Residential
uses recommend a density of 6-34 dwelling units per acre of all housing types. The proposed rezoning from R-1 Residential
to Planned Residential Development for the development of 83 units would bring the density to 23 DUA, aligning with
County Comprehensive Plan goals and contributing to overall housing supply in Albemarle. This request for exception from
the minimum spacing standards is due to the presence of the Church of God Southside adjacent to the property. However, as
a church use, there may be one to two trips occurring during the weekday morning and evening peak hour, with the majority
of overall trips occurring on the weekends. Moreover, the proposed 83 multifamily units do not generate high volumes of
peak hour traffic, as right and left turn lanes are not warranted with this development. Because turn tapers and turn lanes
are not needed with the proposed use, minimum entrance spacing does not have to be established to minimize possible
conflicts with new turn lane infrastructure and existing commercial entrances. Due to the low -volume of trips generated by
this commercial entrance during typical peak hours of the adjacent residential development, meeting half of the required
entrance spacing would not impede on daily safe facilitation of traffic in and around 1805 Avon Street Extended.
