1. C1.0: Recommend list Owner information:
a. County of Albemarle School Board
b. FES / FPC contact
i. Name individual
ii. Tel. # ; email address
2. C2.0: Provide Narrative and schematic elements to accommodate pedestrian bypass across the site (N/S)
during active construction, especially on the west side of Avon Street Ext. Plan must allow pedestrians that
rely on existing pedestrian facilities to transit the site.
3. C3.0: Provide concrete flume detail.
4. C4.0: Since new sidewalk connecting portion of Ex. walk along Avon Street Ext. to Cale Elementary
Parking Lot exceeds VDOT sidewalk standard (ref. IIM-LD-55.16, sheet 3 of 8, 5% Max. for pedestrian
access routes not contained within a street or highway right-of-way; appears to exceed 10%), Engineering
strongly recommends revise this portion of design to include stair with handrail, such that all portions of
sidewalk outside VDOT RW are < 5%. It appears seven (7) — 8" risers would allow remaining walk to
meet 5% standard. Although a portion of walk continues along Avon, and is nearly ADA-complaint, this is
a safe routes to school project, and inherent risk posed to parents, children, teachers, and community with
- 10% proposed grade is somewhat difficult to understand. In winter, especially, risk of fall will persist for
those using this pedestrian facility, unless proposed grade is revised.
Instructional & Informational Memorandum
IIM-LD-55A 6
Sheet 3 of 8
The Pedestrian Access Route surfaces shall be firm, stable, and slip resistant and
openings that are more than 1/2" in one dimension are prohibited. The pedestrian
access route is permitted level changes up to 114" without treatment and level changes
between 1/4" and 112" that are beveled with a slope no greater than 2:1.
Where pedestrian access routes are contained within a street or highway right-of-way,
the grade of pedestrian access routes shall not exceed the general grade established
for the adjacent street or highway. Where pedestrian access routes are not contained
within a street or highway right-of-way, the grade of pedestrian access routes shall be
5% maximum

5. C4.0: Ensure proposed 4" PVC @ 2.0% Min. has sufficient cover.
6. C4.0: Provide safety fence to isolate publicly accessible areas from construction. Also, item I O.o.i.4, below.
7. C4.1
a. Provide SAF. Also, item 6, above.
b. Examine sidewalk grade between proposed contours 585 and 586; this section exceeds VDOT 5%
Max. grade (-6%). Revision is essential since at least one sidewalk along the E side of Avon St.
Ext. serving Cale Elementary must meet ADA guidelines. Engineering recommends all sidewalk
sections be designed < 5%, excepting stairs recommended for section of walk shown on C4.0.
8. C4.2
a. Provide SAF. Also, item 6, above.
b. Item a., immediately above, may require chain -link SAF to separate vehicular /pedestrian paths
from construction.
9. 3_1: Label existing concrete sidewalk as existing concrete sidewalk to be removed.

LOR comments provide advance notice of WPO plan revisions, based on this LOR, additional review
comments are possible once the VSMP /WPO Plan Application is submitted.

Spec-No-9_BIORETENTION_v1-9_03012011.pdf, VA DEQ Stormwater Design Specification
No. 9 to ensure bioretention design criteria are met.
d. Remove sheets C5.0, C5.1, C5.2, C6.0 — 6.4 from the LOR. These sheets (w/ VSMP/WPO plan
title sheet) will constitute a VSMP /WPO plan, and cannot be approved with the LOR.

i. Provide Drainage Area maps (pre- /post -development identical, but need to show
drainage divide/s).
ii. Provide POA analysis. SW quantity evaluation is required at each point of post -

Eugene,
The ACSA offers the following comments:
1. Sheet C3.0 — Show existing water main and sanitary sewer Avon Street Extended. The existing water line along
the western side of Avon Street Extended is depicted on the plan sheet. The existing water and sanitary sewer
line in front and to the side of the school is depicted on the plan sheet.
2. Sheet C3.1 — Show existing water main in front of the school. The existing water and sanitary sewer line in front of
the school is depicted on the plan sheet.
3. Sheet C3.2 — Show existing water main. The existing water line crossing Avon Street Extended and the northern
drive aisle and parking lot of the school is depicted on the plan sheet.
4. Sheet C4.0 — Label existing 8-inch ACSA sanitary sewer main. Add note that MH's must be adjusted to grade in
accordance with ACSA specifications. A label, "8" ACSA sanitary sewer main has been added to the plan sheet.
The grading has been updated in the area so the manhole will not require adjustment.
5. Sheet C4.1 — Show existing water main in front of the school. The existing water and sanitary sewer line in front of
the school is depicted on the plan sheet.
6. Sheet C4.2 — Show existing water main. The existing water line crossing Avon Street Extended and the northern
drive aisle and parking lot of the school is depicted on the plan sheet.
7. Sheet C5.1 — Call our vertical separations between storm sewer and ACSA utilities. Currently there is no new
storm sewer over ACSA utilities. Therefore, is the note still desired?
8. Sheet C9.1 — Is the 24-inch tree existing that sits within the ACSA sanitary sewer easement? Show water main
on Landscape Plan. Yes, there is an existing tree within the existing 20' Sanitary Sewer Easement. The water
main has been depicted on the plan sheet.

Mr. Lynn,
Please find attached the 100% plan submittal made to VDOT and Albemarle County for their review and comment. We
would appreciate your review and provide any comments you may have. Note the plans are subject to change
depending upon comments received from VDOT and the County.
It is still the County's objective to bid the project early next year and construction during the summer while school is not
in session. Please let me know if you have any questions. Thanks for your assistance.
