Given limited number of residential units and roadway length. Engineering does not object to proposed 20' width. Note: VDOT Road Design Manual,Rev.

Apr-2016 revision to VDOT Road Design Manual revises standards that may alter county review. Decisions affecting residents' right to receive public school bus service,including special-needs buses requiring long-interval stationary idling,require cautionary counterbalance to any tendency to approve design alternatives that do not meet all relevant VDOT standards. Reduced radius cul-de-sac(less than typical)on a recent project set uneasy precedent where VDOT standards are concerned. This is to be avoided.

C1.0-Recommend extend stone base 12"beyond edge of pavement. VDOT has approved the proposed section as shown. With this in mind,we have not extended the stone base. 3. C2.0-Show stream buffer. The stream buffer has been added to sheet C2.0. 4. C4.0/C4.1-Revise these sheet titles to:Site Layout. ROAD Plans cannot approve Site Plans. The sheet titles have been revised to read "Site Layout," and the cover sheet index has been updated accordingly. 5. C4.0/C4.1—Show outline of grass channels and extended detention;retain channel/detention labels; show permanent SWM facility easements. Remove other SWM facility/BMP details. Instead reference WPO201600021. Design revision to WPO plan should not require revision to ROAD Plan. The ditch,and stilling basin details are necessary for VDOT review as they are adjacent to the public right-of-way and VDOT maintained culverts.

I did reach out to them on 6/08/16 to confirm that this would not be an issue,and are still waiting for a response. 11. C5.0-Provide VDOT CD-1 at Woodlawn Road, station 17+25, station 18+25,approximately. CD-1's have been provided at these locations. 12. C5.0-Recommend revise profile to read Woodlawn Road. Revised.Woodlawn Road was not available. The developer has decided to use"Valcrest Lane,"and this road name has been reserved with E91 1. 13. C6.0—Note(Culvert A B calculations): I(25)=4.5 in/hr as opposed to 4.8 in/hr—does not require revision. Acknowledged. Unchanged. 14. Recommend include SUB201600066 in ROAD Plan title. Acknowledged.

Perez, Senior Planner Division: Planning Date: April 21, 2016 Subject: SUB2016-66 Woodlawn- Road Plans Fax 434-972-4126 The County of Albemarle Planning Division will grant or recommend approval of the road plans referenced above once the following comments have been addressed: [Each comment is preceded by the applicable reference, which is to the Subdivision/Zoning Ordinances unless otherwise specified.] 1. [14-302(B)5,14400,18-101 Minimum lot size. The minimum lot size in the Rural Areas zoning district is two (2) acres. Lot 2 is proposed as 1.942 acres, which does not meet the minimum acreage for the district. It is suggested that 0.058 acres from Lot 1 be added to Lot 2 to meet the minimum acreage required. If that is not possible omit the 25' dedication to public right-of-way fronting the lot so it will meet the minimum acreage for the district. 2. [Comment] The sight line for the proposed entrance onto Woodlands Road extends beyond the right-of-way line onto TMP 44-12E5. Prior to final subdivision plat approval a line of sight easement shall be obtained over this property. 3. [14-404(A) Condition of Approval] Depict the sight distance for the private entrance. 4. [10.4, 4.6.51 Yards. The front yard setback for Lot 3 is 25 feet. Revise setback note on sheet 1 to include this information. 5. [14-302(A)4&5] Drainage easements. All drainage easements have been labeled as public; however, they are outside of the public right-of-way. Prior to road plan approval either VDOT shall agree to maintain these drainage easements or the easements shall be revised to "Private Drainage Easements " to be maintained by the HOA. If VDOT agrees to maintain the easements provide the following label for the easements `Drainage easements hereby dedicated to public use. " 6. [Comment] Landscaping is not required with this development. It is suggested that landscaping be removed from the road plan. If landscaping is to remain reference to it being "required" shall be removed. Also, the conservation easement is not required but if the applicant intends to keep this feature it shall be platted on the final subdivision plat and a maintenance agreement shall be provided in the covenants and restrictions document.
