RE: Response Letter #1 for SDP2020-66 Albemarle Business Campus — Initial Site Plan
Dear John,
Thank you for your review of the initial site plan for Albemarle Business Campus. This letter contains
responses to County comments dated December 18, 2020. Our responses are as follows:
1. C1, Stormwater Management Notes: Please ref, WPO201800084, Royal Fern Phase 2 rather than
a regional stormwater facility (in addition to referencing more recent ZMA201900003).
Engineering will evaluate WPO plan for Albemarle Business Campus WPO plan against
information and stormwater data approved with WPO201800084. WPO plan approval for ABC is
not automatic with ZMA201900003 approval or satisfied by reference to regional stormwater
facilities for blocks 2-5. WPO plan approval is required for ABC FSP approval. This
development is subject to same or similar SWM program review requirements and criteria as
applied to WPO201800084. Also, see Engineering email to Shimp Engineering, 11/12/2020 2:56
PM, and November 12, 2020 12:04 PM. Please submit WPO plan for ABC at earliest
convenience.
2. It appears that design relies on fewer parking spaces than required by ordinance. There is
potential for ISP disapproval with significant revision required prior even to approval of ISP
(with conditions).
RESPONSE: Comment received. We are working through a parking reduction request with
Zoning.
With final site plan:
3. C5: Revise existing improvements shown on TMP 76-46C 1. See image below (C5 v. satellite
imagery) (attached image and satellite imagery removed in comment response).
RESPONSE: Thank you for bringing this to our attention. These multifamily buildings have been
included in the existing conditions.
4. CS C6
a. Label managed steep slopes.
RESPONSE: Managed steep slopes are now labeled on the existing conditions page.
5. C6
a. Existing grade appears to indicate a SWM facility in vicinity of feature labeled rip -rap.
With WPO, address any SWM quality -quantity implications of removing any existing
SWM facility with proposed development.
RESPONSE: Noted, this was addressed in approved WPO plan, notes copied to SDP.

6. C7
a. Recommend provide sidewalk access to westernmost 24-apt 3-story building via internal
sidewalk rather than walk within public RW along Country Green Road since this is
facility to be used by residents for every trip between vehicle and apartment. This route
so near a public road provides inherent risk, risk analogous to requiring owners of single-
family dwellings to transit walk within public RW to travel between parked car in
driveway and dwelling entrance.
RESPONSE: Noted, if necessary in the future, we will address this comment with the
potential multifamily final site plan.
b. If apartment building access is via sidewalk along Country Green Road and ordinance
requires illumination from parking to dwelling entrance, provide adequate lighting.
Engineering defers to Planning, while reiterating safety concerns for residents if forced to
rely on a walk within public RW of Country Green Road.
RESPONSE: Noted, if necessary in the future, Pedestrian access will be provided with an
internal sidewalk, to be addressed with the multifamily final site plan.
c. Label site entrance radii and relevant entrance geometry.
RESPONSE: Site entrance radii and relevant entrance geometry are now labeled on the
site plan sheet.
7. CT C8
a. Label (typ.) parking space length.
RESPONSE: Parking space length (18') is now included.
b. Label parking lot island radii.
RESPONSE: Parking lot island radii are now labeled on the site plan sheet.
c. Provide, label and revise or reconfigure parking to provide adequate HC parking, with
ramps.
RESPONSE: Handicap parking spaces are shown with this submission.
d. Label CG-12.
RESPONSE: CG-12's are shown and labeled on the site plan sheet.
e. Label CG-6.
RESPONSE: CG-6's are shown and labeled on the site plan sheet.
f. Provide /show /label dumpster pads for each use. No use appears likely able to function
without permanent outdoor solid waste disposal, with possible exception of self -storage,
yet self -storage patrons may wish to avail themselves of trash facility, which may or may
not be required. Hotel, office, and retail space typically (likely) require dumpster pads.
Engineering defers to Planning.
RESPONSE: For the self -storage block, we have provided a concrete pad for (2) 65-
gallon trash totes. Dumpster pads will be provided for the other blocks as needed with
their subsequent final site plans.
g. Please ensure that all parking spaces immediately adjacent to sidewalks are either:
i. 18' L fronting 6' sidewalks, or
ii. 18' L with bumper blocks fronting 5' sidewalks (ref. ACDSM, pg. 17).

8. C8
RESPONSE: Comment received. Please see the labeled parking space lengths and
sidewalks with this submission.
a. Label block 2-5 development entrance radii /relevant entrance geometry at Old
Lynchburg Road.
RESPONSE: Entrance radii has been provided.
b. Label angle for angled parking.
RESPONSE: The 60' angle label has been added.
c. Provide angled parking dimensions for comparison with ordinance requirements
/ACDSM.
RESPONSE: Angled parking dimensions are included for review.
d. Label site features (walks, crosswalks, traffic control signs).
RESPONSE: Comment received. Please see the updated site plan sheet.
e. Provide internal and external stop /yield signs to define stop /thru traffic patterns.
RESPONSE: Comment received. Appropriate traffic control signs have been provided
with this submission. As the other blocks are subsequently developed, additional traffic
control signs will be proposed.
f. Since site access from 5th Street spans property line with parcel to east, provide legal
instrument that allows site access. Existing legal instrument (201800013730) presents
obsolete image. Provide instrument specific to current geometric design of Wahoo Way
(attached image removed in comment response).
RESPONSE: A new access easement will be recorded prior to final site plan approval.
g. Provide /show /label hotel loading space.
RESPONSE: This comment will be addressed with the hotel's final site plan.
h. Clarify via label /dimension the short arc -pedestrian facility at intersection Wahoo Way
and 5th St. to clearly define how 10' multi -use path along 5th St. connects with 5' walk
along Wahoo Way,
RESPONSE: Clarification will be provided via labels/dimensions with Block 3 (offrce)'s
final site plan. This path will be provided with Block 3 final SDP.
9. C9: Label island dimensions and curb radii at right -in /right -out entrance on Old Lynchburg
Road.
RESPONSE: Entrance/curb dimensions are provided on the site plan sheet.
10. C10
a. Provide spot grading near islands to ensure runoff reaches inlets without nuisance
ponding.
RESPONSE: Comment received. Spot grading is provided on the grading plan.

i. Recommend label private drainage easements.
RESPONSE: Private drainage easements are not proposed at this time. Public
drainage easements shown.
ii. Label public drainage easement downstream of proposed SWM facility.
RESPONSE: Public drainage easements are now labeled on the site plan.
iii. Public SWM facility and public drainage easements require plat with deed, and
recordation prior to FSP approval.
RESPONSE: Comment received.
iv. Acquire and reference recorded public drainage easement across TMP 76-46C 1
(Mountainwood Properties) that receives ABC development runoff.
RESPONSE: This is no longer applicable, however this would be provided with
the potential future Block 1 apartments development.
v. Ensure post -developed storm runoff across TMP 76-46C1 is non -erosive.
