Subject: SUB - 2009 -00062 Wickham Pond Phase II Block I - Preliminary Plat
The first revision to the preliminary plat for the Wickham Pond Phase H Block I, received September 13,
2010, has been reviewed. Current Development Engineering has the following comments:
Preliminary Plat Comments
1. The parcel of development is incorrectly labeled as TMP 56 -91A, please re -label correctly as TMP
56 -91. Also, TMP's 56E -2A and 56E -2B are labeled with the incorrect owner. [14- 302(B)(6)]
(Rev. 1) Comment has been addressed. Though, now the owner of the parcel stated on the plan
does not match the owner listed in our GIS system. If TMP 56 -91B is owned by a different
company than 56 -91, then a letter of intent is needed for approval of the preliminary plat for
Phase II Block 1.
2. Please add a note that this parcel is in the Lickinghole Creek Watershed, an Albemarle County
Water Supply Protection Area. [14- 302(B)(7)]
(Rev. 1) Comment has been addressed.
3. Please show the existing 100 -foot stream buffer on the stream which flows through the
southwestern corner of the property as shown on the Albemarle County GIS maps. Please also add
the following note, "The stream buffer(s) shown hereon shall be managed in accordance with the
Albemarle County Water Protection Ordinance ". [14- 302(B)(10)]
(Rev. 1) Comment has been addressed.
4. It appears the critical slopes within the southwest area of the parcel will be disturbed during
development. Please submit a written request and justification under section 4.2.5 of the zoning
ordinance for a waiver authorizing the disturbance of critical slopes. [14 -304]
(Rev. 1) The critical slope waiver has been received. Engineering analysis of this waiver
request will be provided in a separate document.
5. Will a dumpster be installed to serve trash needs for the 8 -unit building on Lot 142? If so, where
is its expected location?
(Rev. 1) The 8 -unit building has been replaced with 8 townhouse style units which will
presumably be served by normal residential waste disposal services.
6. Please extend Ditch 2 to catch run -off from the portion of Wickham Way that will release
uncaptured into TMP 56 -91A.
(Rev. 1) Comment has been addressed.
Ditch 1 may need to be designed as a Water Quality Swale (or flow directed to another BMP) in
order to meet the requirements of the Water Protection Ordinance.
(Rev. 1) Stormwater facilities have been added to this drainage area. Comments from a
detailed review of the WPO plan will be provided in a separate document. For purposes of
preliminary plat approval, the plan meets all Stormwater Management requirements set by
county engineering.
14. (Rev. 1) The current layout of the affordable units does not match the approved application
plan. A variation from the Planning Department may need to be processed before the
preliminary plat can be approved.
15. (Rev. 1) Please remove the multi family building from all sheets; the lots can be shown as
currently drawn. If the building was to remain, this plan would have to be called a site plan
and begin the SRC process with all of the site plan requirements. If approved by Planning, the
townhouse units should be filed as a site plan at a later date. The duplex lots may remain on
the subdivision plat.
16. (Rev. 1) Proffer #4 from ZMA- 2005 -00018 states that if the western facing facades of the Phase
I townhouse units adjacent to Block 2 of Phase II are not evocative of a front entry elevation, a
landscape buffer on Block 2 will be required. The western facing facades of these units are not
evocative of a front entry elevation and a buffer will be required. Because the design of the
buffer was not identified during the rezoning application, it must meet the minimum
requirements of 18- 32.7.9.8. The road must be moved to the west so this 20ft of landscape
screening may be provided in the future (when the site plan for Block 2 is submitted for ARB
review). The matter is further complicated by the -]Oft of ACSA easement centered on the
eastern property boundary since screening vegetation is prohibited within most ACSA
easements. The road ROW for Wickham Place must be placed at least 20ft off of the eastern
boundary of Block 2. The ROW may need to be moved 30ft if ACSA will prohibit the screening
vegetation from the sewer easement. If the applicant wishes to modify the facades of the
existing houses, a letter of intent from TMP 56J -A will be required prior to approval of the
preliminary plat.
17. (Rev.]) I have some concerns with the conceptual phasing plan proposed by the applicant.
a. Wickham Place from Wickham Way to Route 240 and all associated intersection
improvements must be constructed within the first phase.
b. At all phase lines, the road and alley plans must be designed with acceptable temporary
turnarounds. The preliminary plat maybe able to be approved as shown in this regard,
but the road plans will need to be modified.
c. The phase lines should include all necessary associated infrastructure (drainage pipes,
water and sewer lines, etc.). For instance, the Phase 1 limits should include the
drainage structures from 137 and 149 to 101.
These phasing lines can be removed from the preliminary plat and handled with the review of
the road and drainage plans if preliminary approval is desired now.
18. (Rev. 1) The north side of Wickham Way and west side of Wickham Place require a sidewalk
unless waived by the Planning Commission.
19. (Rev. 1) Engineering review will note at this time that it appears the modification to the VDOT
street standards in July of 2009 would allow many of the subdivision streets (denoted by I in
Figure 4 of the rezoning plan) to be reduced in width. County engineering review has no
objection to the reducing of the pavement widths to the latest VDOT standards. Please confirm
with VDOT that they would consent to a reduction in cross section width before modifying the
design.
