The following comments are provided. A WPO plan will not be required if the total disturbance for construction of the tasting room and adjustment to the visitor parking lot is kept under 10,000sf. If disturbances pass this mark, an ESC plan will be required. 2. In conversations with Lisa Glass, the applicants have stated their desire to keep the space between the farm buildings a private agricultural/production area and provide public parking north of tasting room and market. Please clearly show this on the drawing by providing signage restricting access to the cidery operations area between the buildings. 3. Please accurately show all existing gravel areas and other important site features. 4. Please provide more spot elevations around each of the buildings and parking areas. The spot elevations should clearly show that adequate drainage is achieved on the site. 5. The plan has been designed to parameters less stringent than the standards listed in the County ordinance. A waiver of the following standards will need to be granted by the Zoning Administrator: a. [18- 4.12.15.a] Surface materials. b. [18- 4.12.15.c] Maximum grade in parking areas. c. [18- 4.12.15.g] Curb and gutter. d. [18- 4.12.17.a] Maximum grade for access aisles. e. [18- 4.12.17.c.1] Minimum width on two -way access aisles. f. [18- 4.12.16.] Design requirements for parking spaces An engineering analysis of the pending waivers is as follows: a. [18- 4.12.15.a] The applicant does not wish to pave the entrance drive, parking lot, and internal operation area. In place of pavement, gravel surfacing will be used throughout the site. The applicant cites that the rural character of the site and the low trip generation do not justify surface paving. (It should be noted that engineering review does not consider the rural character of the site in making its recommendation.) I estimate that between 50 and 75 cars a day will be frequenting the cidery and farmers market during the peak season. I used this estimate of daily traffic to calculate the required thickness index through VDOT's Pavement Design Guide for Subdivisions and Secondary Roads. The result of this calculation is a thickness index between 5 and 6 inches which is comparable to 5 or 6 inches of gravel. The existing gravel drive is currently in stable condition but increased traffic loads could be a concern to future stability. Current Development Engineering Review Comments Page 2 of 2 b. [18- 4.12.15.c] The existing slopes of the area to be used for parking are anywhere between 3% and 7 %. A strict enforcement of the maximum parking grade requirement would necessitate considerable excess grading. Engineering recommends approval of the waiver of maximum grades in parking areas. c. [18- 4.12.15.c] Stormwater runoff is always more efficiently transferred with curbing. However, if the parking lot is not surfaced, the benefit of curb and gutter is greatly reduced. Engineering review recommends approval of the waiver of curb and gutter for the parking area if the surface requirement is also waived. d. [18- 4.12.17.a] The existing drive to reach the parking lot adjacent to the cidery tasting room has a small section of the roadway that appears to be steeper than 10 %. The roadway is not shown on the current site plan so a field visit was the basis of my assessment. Engineering review recommends the waiver of the maximum grade of a travelway be granted because the portion of the steep roadway section is short and does not present a safety or emergency access problem. e. [18- 4.12.17.c] From State Route 29 to the tasting room, the width of the travelway ranges from 12ft to 16ft. Due to the trip generation of the site, instances where vehicles have to pass one another head -on will be infrequent. When vehicles do have to pass one another there is room on the shoulder for most of the travelway for one vehicle to pull over. The most restrictive location along the travelway is the dam crossing where the actual travelway is 14ft and the distance between both guardrails is 16.5ft. Engineering review recommends approval of this waiver. f. [18- 4.12.16] The applicant has not shown any information regarding the parking configuration on the first plan. Engineering review recommends that the parking area be configured in accordance with all design standards listed section 18- 4.12.16 and a waiver of this section not be granted. If surface requirements are waived for the parking area, delineation of parking spaces should be designated by bumper blocks. The use of wooden railroad ties as bumper blocks is acceptable if the applicant wishes to avoid the use of concrete blocks. All parking spaces should be protected from vehicles traveling through the lot [4.12.151]. File: El_psp_PBC_sdp20080007O
