RE: SUB2015 -066 Wayland's Ridge- Preliminary Plat
Mr. Shimp:
The Agent for the Board of Supervisors hereby grants administrative approval to the above referenced
subdivision plat.
This approval shall be valid for a period of five (5) years from the date of this letter, provided that the
developer submits a final subdivision plat for all or a portion of the site within one (1) year after the date
of this letter as provided in 14 -226 of the Subdivision Ordinance of the County Code, and thereafter
diligently pursues approval of the final subdivision plat.
The final subdivision plat will not be considered to have been officially submitted until the following
items are received:
1. A final subdivision plat that satisfies all of the requirements of 14 -226 of the Subdivision
Ordinance.
2. A fee of $1,230.
Please submit eight (8) copies of the subdivision plat to the Community Development Department and
three (3) copies directly to ACSA. The assigned Lead Reviewer will then distribute the plans to all
reviewing agencies. Once you receive the first set of comments on the final subdivision plat, please
work with each reviewer individually to satisfy their requirements.
The final subdivision plat will not be approved until the following conditions are met:
The Department of Community Development shall not accept submittal of the final subdivision plat for
signature until tentative approvals for the following conditions have been obtained:
Planning Division Approval of (2 copies):
1. A subdivision plat meeting the requirements of 14 -226
2. [Section 2.2.3 Open Space; 4.7 Open Space Requirements] Cluster developments (Lots less than
30,000sf) require a minimum of 25% open space. Not more than eighty percent of the open
space can be located within the flood plain. If open space is not provided, lots must be a
minimum of 30,OOOsf and have a minimum frontage of 100 feet.
,imitation on certain elements. If open space is required by this chapter, not n-iore than
eighty (80) percent of the rnininuun required open space shall consist of the following: (i)
land located within the one- hundred year flood plain_ (ii) land subject to occasional,
common or ffi-quent flooding as defined in Table 16 Soil and 'Water Features of the
Uluted States Departinent of Agriculture Soil Conservation Ser4'ice, Soil Sui -vey of
Albemarle County, Virginia, August, 1985; (iii) critical cT presen-ed slopes; and (iv) land
devoted to stonnt�ater amnagenient facilities or flood control devices, except where the
facility or feature is incorporated into a permanent pond, lake or other water feature
deemed by the agent to constitute a desirable open space anieruty.
3. [Density Bonus] For the maintenance of wooded areas: Show where the areas are and provide a
conservation plan. The wooded areas must meet the definition in order to qualify (see below).
Also, state the calculations in the Area Summary table.
The wooded areas must be outside of the dedicated land to the County, as well as, not within
the proposed lots in order to assure maintenance.
Mooded area, forested m-ea: An area contaniing one of the ruin u n munber of trees of specified
size; or combinations thereof, from the following table:

4. [Density Bonus] For the street trees: no easement is shown along the proposed roads, provide
the easement. Show the trees and provide the required information per 32.7.9.
5. [Density Bonus] The park land to be dedicated must be approved by the Board of Supervisors. It
was advised that the applicant take the proposal to the CCAC, did this occur? What was the
feedback from that meeting? If this has not been to the CCAC, coordinate with me so that I can
attend.
6. [14- 302(A)(3)] It appears that the right of way for Road 'B' will be extended to the property
lines, will this be dedicated to public use? If so, state "dedicated to public use" and state the
width. Also, the proposed cul -de -sacs are outside of the right of way. They should be within the
right of way.
7. [14 -422] Sidewalks must extend all around the proposed cul -de -sacs. Also, it appears that the
cul -de -sac is not within the right of way. Revise to have the cul -de -sac within the right of way.
S. [14 -422] It appears that the proposed property lines are within the proposed sidewalks and
landscape strips. The landscape strips and sidewalks need to be within the right of way.
9. [14- 302(A)(7)] Show the existing property lines. This proposal is made up of two separate
parcels which must be shown, and if combining show the boundary line adjustment land hooks.
10. [14- 302(A)(12)] The entrance is located within the preserved slopes, however the entrance may
need to be moved to provide less impacts to these slopes. Provide the information required by
VDOT to determine if the entrance is located in the best possible location and cannot be moved
to the south to lessen the impact.
C. Necessaiypifblic facilities_ Public facilities necessary to allow the use of the lot,
provided that the lot does net contain adequate land area outside of the
preserved slopes to locate the public facilities and one Or more of the following
exist: (1) the laud disturbing activity avoids impacts on other protected resources
such as stream buffers or floodplai -, (n) the alignment of the public facilities is
consistent with the alignment of public facilities depicted Or described ui the
comprehensive plan; (iii) the disturbance is necessary to provide interconnection
required by the Code or the applicable regulations of other public entities; or (iv.)
prohibiting the facilities from being located on preserved slopes will cause an
unnecessary hardship_ To the extent that public facilities are established on
preserved slopes, the preserv. ed slopes should be preserved to the lnaxinnuli
extent practicable consistent xv-ith the intent and purpose of this overlay district.
11. [14- 302(A)(14)] On the front cover it states that 4.56 acres dedicated to Albemarle County. Does
this include the park dedication and the right of way? If so, separate out the two. If it is only
intended to be the park area, then clarify if the dedication is 4.56 acres as stated on the front
cover, or 1.6 as stated on sheet 2.
12. [14- 302(B)(7)] State that the property is within the Lickinghole Creek water supply watershed.
Please contact Megan Yaniglos at 296 -5832 ext 3004 if you have questions or require additional
information.
Engineering Division Approval of (1 copy of subdivision plat; WPO and Road plan number stated in
application):
1. Entrance is crossing preserved slopes. This is okay without a rezoning if we find there is no
reasonable alternative. Confirm with VDOT.
2. Verify the ditch line is running north adjacent to Crozet Ave. I recommend this resolved now so
you are not proposing a grass swale next to another ditch. This will impact design of the channel
to the biofilter. Also, clarify how the pipe outlet at entrance will be conveyed into the grass
channel. It appears to be uphill.
3. Provide more backyard for lots 4 -6. Cut slope back.
4. Clarify grading and drainage for lots 10 -15 and 17 -19. It appears runoff will flow towards homes
and into the garage. Are you providing trench drains at end of driveway before the garage?
Driveway grading should be away from garage and pitched to one side. This is typical
construction. For example lot 10 and lot 20 with a crown does not work well. Revise.
5. Clarify type of dwelling. This may help resolve comment #4.
6. Grass channel is a BMP facility. This should be off lots. Create a special lot or show in open space
for grass channel. Another option is to provide a normal swale just to convey runoff with inlets
at every 3 lots. This will not be counted for quality.
7. Label road as public.
8. Show conceptual pre- treatment area. This is to verify you have enough room for BMP.
9. Engineering Review Comments Page 2 of 2
10. Location of biofilters will work better on the other side of the road. I recommend to relocate. I
also recommend resolving this at the preliminary stage to verify there is enough room for the
BMPs with the proposed number of lots.
11. Otherwise, address concerns listed below prior to the approval of the preliminary plat:
a) Verify there is enough room for the embankment.
b) The standards states no more than 1' ponding for biofilters. In cases of larger storm events
verify that it can bypass biofilter. Runoff should not overtop embankment and spill into road B.
c) Avoid short circuiting. See location of pipes into biofilter.
12. Both future extensions will need to be verified by planning to clarify how the R/W should be
shown around the cul -de -sac.
Address for Final Subdivision Plat:
(Additional comments may be added or eliminated based on further review)
1. Lot 10 -16 driveways should not exceed 16%
2. Proposed contours should be 2' contours.
3. Show CG -6 around cul -de -sac to avoid runoff towards retaining wall.
4. Show retaining wall design. Any walls supporting roads require engineered plans (not generic
manufacturer's details) and computations.
5. Verify classification of trail and provide a detail that meets Albemarle County Design Standards.
Trails should be in common areas, and maintained through neighborhood covenants or private
agreements. When not in common areas, all trails are required to have easements, which must
be a minimum of 10' wide. Concentrated runoff must not run across the trail and where a
nonpaved surface is used, trail breaks and erosion prevention measures must be used on grades
above 7% to prevent repeated washout of the surface.
6. Provide outlet protection at the end of culverts from biofilter.
Please contact Michelle Roberge at 296 -5832 if you have questions or require additional information.
