VirginiaDOT.org COMMISSIONER January 29th, 200 Mr. Glenn Brooks Department of Engineering and Development 401 McIntire Rd. Charlottesville, VA 22902 Subject: Site Review Meeting Continents February 1 st, 2007 site review meeting Dear Mr. Brooks: Below are VDOT's comments on the Site Plans for the February 1 st, 2007 Site Review Committee Meeting: SDP - 2007 -00001 Martha Jefferson Hosaital Preliminary (David Pennock The design speed needs to be indicated on the plans. It appears that the plans are designed to a 25mph design speed. The minimum should be 30mph. The desirable crossover spacing is be 500 feet and the minimum is 450 feet. Intersection "D" does not provide enough distance between crossovers. Sight distance lines need to be shown on the plans. The minimum intersection sight distance is 355 feet for 30 mph design speed. Where the sight lines go outside the proposed R/W, an easement will need to be provided and must stay clear of sight obstructions. Road plans will need to be provided and include horizontal and vertical alignments and data, typical sections, mainline and entrance profiles, pavement design with computations, and drainage computations. The plans should also include projected traffic and dimensions of features such as turn lanes. All road plans, intersections with public and private roads, and entrances need to be designed in accordance with VDOT's Road Design Manual, The Road and Bridge Standards, and the Minimum Standards for Entrances to State Highways. SDP - 2007 -00002 Meadows Expansion Preliminary (Summer Frederick All connections to Rte. 1230 need to be designed in accordance with VDOT's Road Design Manual and The Minimum Standards of Entrances to State Highways. The plans needs to include all dimensions of proposed roads and entrances along with horizontal and vertical data. Tit ANSPORTATtOM EXf Er tE1i4E 4 m 5 1 rJ t1 Sight distances need to be shown on the plans. All work within the VDOT R/W needs to be permitted by VDOT's Charlottesville Office. The plan needs to provide pavement calculations and drainage calculations. Sidewalks within the VDOT R/W need to include CG -12 detectable warning surface. SDP- 2007 -00009 Westhall Phase V Lots 90, 91, 92 (Patrick Lawrence) Lot 90 -- If a driveway is to be proposed on Park Road from this lot, the entrance needs to be entirely outside of the radius between Park Road and Westhall.

County of Albemarle Department of Community Development Memorandum To: David Pennock, Current Development planning and zoning review From: Glenn Brooks, County Engineer Date: 23 Feb 2007 Subject: Martha Jefferson Hospital, critical slope waiver request (SDP200700001) The critical slope waiver request has been reviewed. The engineering analysis of the request follows: Description of critical slope area and proposed disturbance: These are hillsides and areas of former grading in Peter Jefferson Place. Areas Acres Total site 38.27 acres (new lot 11) Critical slopes 5.29 14% of site Critical slopes disturbed Almost all 90% of critical slopes Exemptions to critical slopes waivers for driveways, roads and utilities without reasonable alternative locations: Most of these disturbances are exempt because they are part of the roadway grading for Peter Jefferson Parkway and for Willis Drive and for the stormwater management and erosion control facilities necessary for the site. In addition, these disturbances are part of an approved rezoning application plan. The layout of these plans is such that reasonable alternatives to these disturbances are not possible without changes to the rezoning. The portions of criticial slopes that are not exempt (approximately 0.5 acres) are under parking areas and buildings. Below, each of the concerns of the Zoning Ordinance is discussed for these remaining critical slopes. Compliance with Zoning Ordinance 18 -4.2: movement of soil and rock" The building and parking areas will replace slopes, and movement of soil should not be an issue. excessive stormwater runoff' Stormwater runoff will changes, as the slopes will be eliminated, and the stormwater plan will eliminate excessive discharges. siltation" Inspection and bonding by the County will ensure siltation control during construction. Since the slopes are mostly eliminated, long term stability should not be an issue. loss of aesthetic resource" Visibility from other areas of Albemarle was addressed with the rezoning. septic effluent" This neighborhood is serviced by public sewer. Albemarle County Community Development Engineering Review comments Page 2 of 2 Based on the review above, there are no engineering concerns which prohibit the disturbance of the critical slopes as shown.
