' No concrete curb or sidewalks, but VDOT may request concrete reports for wingvalls; photo, below. ' . RGA As -built is not sealed, but stamped Progress Print -this is unusual (unacceptable). For bond release: 1. Acceptance of public street by VDOT (Phase B2&B4 streets: Warbler Way and Dubine Drive). 2. Provide As -built pavement design using (as -built) base /surface asphalt values /depth and F&R CBR values. a. F&R reports for Warbler Way: Sta. 11+00, 24+00, 31+00: CBR values 10.8, 8.8/6.7, 5.9, respectively. b. BM25 base asphalt thickness for Warbler Way, Sta. 10+50 to Sta. 19+50 ("as specified"). F&R report bituminous density report, 11/14/2016, for samples collected 11-5-16 indicates 4" BM25, Sta. 20+35-33+00. Please provide explicit reference to base asphalt thickness (3" BM-25.OA required), Sta. 10+50 to 19+50. See 7/29/16 F&R field report date; Engineering Review Comments Page 2 of 7 Determination: As specified. Engineering requests confirmation that 3" BM-25.OA was placed, 7/29/16 or other date/s, or, alternatively, 4 core samples evenly distributed along Warbler Way Sta. 10+50 — 19+50 to determine base and final asphalt depths for this section of Warbler Way. c. Ensure As -built condition meets design (DP > D,). Ensure As -built drawing captures or reports this information (As -built pavement section meets design, though layer depths may vary). 3. A resident drew attention to grade at eastern edge of Warbler Way cul-de-sac, which appears to form a depression in pavement with effect grade may concentrate storm runoff across cul-de-sac and direct runoff toward Lot 68. Non -positive cul-de-sac grade would pose issue for Albemarle NDOT during road acceptance process. County requests Engineer confirm positive grade exists at eastern edge of cul-de-sac, that runoff at this location has no tendency to concentrate, and is sheet flow. Design shows sheet flow from cul-de-sac; As -built condition should match design. 4. Patch asphalt at water valve lid; photo, below. 5. Establish ditch grade (Lot 70), per As -built sheet 1 road section (3:1, 2:1 side slopes). As -built ditch flattens where it turns toward driveway pipe (see photo), which, according to resident, causes runoff to jump relatively flat grade to paved surface of Warbler Way /cul-de-sac. Revise grade to match road section to ensure runoff is conveyed to driveway pipe, Lot 69, to eliminate tendency of storm runoff to skip onto paved surface. 6. Recommend increase paved radius (2'-3') at intersection Warbler Way and Victor Place since off - pavement vehicle wheel tracks may create first -year maintenance issues, or thereafter. Photo, below. 7. Provide As -built pavement design for Dubine Drive using (as -built) base depth (surface asphalt not placed as of date of inspection; see photos, pp. 5-6, this report) and F&R CBR value; 8_4. a. F&R report for Pine Knot Road [Dubin Drive] center of cul-de-sac; test date, 2-Jun-16. b. Construction binder includes base stone (21A), compaction, and utility trench installation reports. Engineering cannot locate base asphalt reports for Pine Knot Rd (Dubin Dr); please famish base asphalt reports for Dubine Drive, or core samples that verify BM25 3" depth. 8. As -built (AB): a. Submit sealed As -built drawings with future bond reduction or release requests. b. Ensure assigned street names are shown on As -built drawing. For example: Dubine Drive, rather than Pine Knot Rd. i. Ref. F&R Ensure county road name signs /posts meet requirements at Road Naming and Property Numbering Ordinance and Manual, rev. Oct-20, 2021, especially sign /lettering reflectivity: c. Confirm as -built grade at east edge of Warbler Way cul-de-sac; that pavement is crowned, without reverse (swale-like) pitch that may concentrate runoff and direct it toward Lot 68. Photo, below.
