Subject: SDP200900020, Tabor Presbyterian Church Addition - Preliminary Site Plan
The revisions to the preliminary site plan for the Tabor Presbyterian Church Addition, submitted on July
31, 2009, has been reviewed. Current Development Engineering can recommend approval once the
following comments have been addressed:
General Site Plan Comments
Please revise the Field Notes on Sheet 2 to state that this property is in the Lickinghole Creek
Watershed [18- 32.5.6.f].
REV #l: Comment has been addressed.
2. The existing concrete sidewalk adjacent and parallel to Tabor Street should be extended to the
western edge of TMP 56A2 -1 -12 with this site plan [18- 32.7.2.8]. The Downtown Crozet District
zoning requires new sidewalks to be 8 -feet wide [18- 20B.7.A]. The applicant may request a
waiver of the width requirement under the provision in 18- 2013.7.1), this is an administrative
waiver to the Chief of Current Development. The VDOT standard for sidewalk width on an
Urban Local road without curb & gutter is 4 -feet.
REV #1: Comment has not been addressed, sidewalk has not been extended.
REV #2: The requested sidewalk will be constructed with the Crozet Streetscape Project by
Albemarle County's Office of Facilities Development. However, the proposed sidewalk is only
6-feet wide. A request for waiver of the width requirement will still need to be granted by the
Chief of Current Development. It is unclear with which project the waiver request will be
required — Tabor Church or Crozet Streetscape. Although OFD is installing the sidewalk, the
Tabor Church project can not progress without approval of the waiver.
Hard surface and curbing are required on all new parking lot travelways (18- 4.12.15). Written
requests providing justification for a waiver of these requirements must be submitted with this site
plan [18- 32.5.3]. Please calculate and include the design ADT for the travelway, and the required
pavement section based on that ADT, using VDOT pavement design guidelines. [18- 4.12.15.a]
REV #1: Comment has not been addressed, a waiver request has not been received.
REV #2: Waiver requests have been received.
Waiver of Surface Material: Current Development Engineering is satisfied that the proposed
gravel surface is adequate to serve the projected use of the travelway and can recommend
approval of the waiver.
Waiver of Curb & Gutter: The county engineer has been asked to waive or modify this
requirement as deemed necessary to accommodate stormwater management /BMP facility
design [18- 4.12.15.gl. Current Development Engineering does not find that the installation of
curb & gutter on the proposed travelway would interfere with the proposed stormwater
management "rain garden ". Allowing sheet flow off of the travelway does not ensure that this
stormwater will get to the rain garden for treatment. Curb & gutter may better serve the
purpose of directing the flow to the facility. Engineering cannot approve the waiver for
stormwater management purposes.
4. Alley right -of -way or easement width should not be less than 20 feet. The Chief of Current
Development may authorize an alley with a lesser width. [ 18- 32.7.2.5, 14- 410(D)]
REV #1: Comment has not been addressed, Chief of Current Development has not been asked
to authorize a width less than 20 feet.
REV #2: Comment has not been addressed.
5. One -way access aisles may be approved if a public street is not part of the circulation loop. [18-
4.12.17.c.2] It appears that vehicles will loop back onto Tabor Street to reach the existing parking
lot after circulating through the one -way drop off. A waiver of this criteria may be requested
under section I8- 4.12.2.c.
REV #l: Comment has been addressed, direction of travelway has been reversed so that public
street will not be part of the loop.
6. Per VDOT standards, a commercial/private entrance onto public street shall have minimum return
radii of 12.5 feet and a minimum width of 14 feet for one -way traffic.
REV #1: Comment has been addressed.
Please show sight distance triangles at the new entrance.
REV #l: Comment has not been addressed.
Stormwater Management Comments (for information purposes only)
The conceptual stormwater management plan appears adequate. Stormwater management
calculations and design will be reviewed once a WPO application has been submitted.
Engineering approval of the Preliminary Site Plan does not include approval of the proposed
stormwater management plan.
REV #l: Comment has been noted.
9. The culverts under the existing entrances and the roadside ditch along Tabor Street appear to need
maintenance. Calculations for the culvert and ditch capacities will be required with the WPO
application. The roadside ditch may need to be replanted with sturdier vegetation, or lined if
velocities warrant. The adequacy of other downstream pipes may also need to be checked.
REV #1: When preparing final plans, please coordinate with County project to improve Tabor
Street /Crozet Avenue intersection. Contact Jack Kelsey in Albemarle County Facilities
Management.
REV #2: There appears to be a grading conflict between the Church's and Library's proposed
plans. The proposed Church gravel drive will be more than 5 feet higher than the library's
proposed parking lot and there is very little room to make up this grade difference. Although
the gravel drive around the Church is not the "ultimate condition'; the two plans that are
currently being reviewed need to be consistent for approval. Please coordinate the proposed
final grades to ensure they can be reconciled.
Final Site Plan comments (for information purposes only)
10. Temporary grading and construction easements will be necessary from TMP's 56A2 -1 -15 and
56A2 -1 -18.
REV #l: Comment has been noted.
