Request to rezone 11.886 acres from RI to PRD approved. Design Planning staff comments were
provided during the review of the rezoning. The character and appearance of the stormwater
facility and landscaping along the EC frontage were identified as primary issues.

This proposal is an extension of the original Avinity development that fronts Avon Street Extended and was reviewed and approved between 2007 and
2010. In November 2014, a Zoning Map Amendment (ZMA-2013-16) to rezone 11.886 acres between the Avinity I development and Route 20
(Scottsville Road) was approved. This development proposes 51 single-family attached units, 51 townhouse units, and a clubhouse. The proposed
development will have access to Route 20 as well as Avinity 1. The ARB will review this development for the first time at the January 8, 2018 meeting.
(The project was originally slated for the November 6, 2017 ARB meeting but was deferred at the request of the applicant; a resubmittal was received by
staff on November 9, 2017 and the project was slated for the December 18, 2017 ARB meeting but was deferred again at the request of the applicant to
January 8, 2018.)
VISIBILITY
The project area abuts the EC street (Route 20 South) in two places: 1) a pipe stem which holds an emergency access road north of the Kappa Sigma
Headquarters property, and 2) 0.87 acres of open space with 260' of frontage to the south of Kappa Sigma that includes one of three proposed stormwater
management facilities. Both will be visible from the EC.
The topography of the site rises steeply westward [Figure 1]; therefore, the roofs, sides, and upper portions of the rear elevations of the single-family
attached units in Block C and Block D are expected to be visible, as will be the upper portions of the elevations and ridgelines of the townhouses in the
interior Block A. For instance, the FFE at lot 38 is 534 and rises to 568 at lot 24. Therefore, the roofs of lots 83-86 (with FFEs of 554 to 556) will be seen
over lots 39-48 (with FFEs of 527 to 547) while townhouses on lots 87-102 may be seen incrementally through the single-family attached unit lots 49-61,
as their FFEs are greater by 1-3 feet. Lots 14-17 (FFE 568) will rise above lots 78-87 and lots 39-48. Large portions of the rear (north) elevations of lots
39-48 may be visible; the side (east) elevation of 39 is the closest to the EC and will be visible; the majority of the front (south) elevations of lots 39-43
may be visible at the intersection of Route 20 with Pebble Drive; and the side (east) elevation of lot 38 will be visible. The rear elevations of lots 49-61
(Block C) and possibly the (east) side elevation of the proposed clubhouse will be visible from the EC through the Kappa Sigma property, despite a
single row of tree planting and fencing.

landscape buffer on the east boundary of the
SWMF parcel tapers from 8' in the north to
4' in the south on the Layout Plan (sheet
3A) and Landscape Plan (sheet 9A), but is
drawn as consistently 4' wide on the Utility
and Grading plans (sheets 4A and 5A).
While no access road is shown on the
Layout Plan (sheet 3A) and Landscape Plan
(sheet 9A), it is drawn on the Utility and
Grading plans (sheets 4A and 5A).
Furthermore, while the landscape buffer on
the east side of the entire development is
labeled as 6' wide, the scale shows the
measurement as 5' wide. These
inconsistencies must be addressed. The
access road will not have an appropriate
appearance for the EC. It would have less
impact if located on the west side of the
basin, and if landscaping were arranged to
screen it and integrate it into the
surroundings.
Furthermore, two retaining walls, each
measuring 6' tall, appear on the west
boundary of the SWMF 0.87-acre parcel;
although they are landscaped with
shrubbery, they add to that engineered
appearance which was not portrayed in the
approved plan of ZMA-2013-16. At Route
20, the elevation is 490'; the bottom of the
first retaining wall is at 506' while the top of
the second wall is at 520'; thereby, the walls
will be highly visible above the EC grade.
A 3-board fence is proposed along the EC
frontage, and the north and south sides of
the SWMF. The fence will not provide
screening, but could contribute to the
creation of an appropriate rural -character
landscape/streetscape. A similar treatment
was approved for the Cascadia stormwater
facility adjacent to the Route 20 EC [Figure
5]. That facility (which is much larger than
this SWMF) is in place, but the landscaping
and fence do not appear to be complete. The
facility is very visible from the EC.

Areas designated for preservation in the final Certificate of
Appropriateness should be clearly delineated and protected
on the site prior to any grading activity on the site. This
protection should remain in place until completion of the
development of the site.

Preservation areas should be protected from storage or
movement of heavy equipment within this area.
44
Natural drainage patterns (or to the extent required, new
drainage patterns) should be incorporated into the finished
site to the extent possible.
SUMMARY OF RECOMMENDATIONS
Staff recommends the following as the primary points of discussion:
1. Visibility of the development from the EC; architectural drawings required for the next submittal.
2. Treatment of the stormwater management facility adjacent to the EC.
3. Frontage landscape treatment
Staff recommends that the ARB forward the following recommendations to the Agent for the Site Review Committee:
• Regarding requirements to satisfy the design guidelines as per § 18-30.6.4c(2), (3) and (5) and recommended conditions of initial plan approval:
