This review does not include a review of Erosion & Sediment Control, Mitigation, or Stormwater Management (WPO plans). Please note a separate application and fee for review of these plans is required. Please adequately address the following comments for preliminary site plan approval: A. Application Information 1) Per application plan for Old Trail Village, Road B and Road I are proposed to be public roads. Please submit a separate set of road plans including proposed drainage and profiles for Road B and Road I. Please note this will affect proposed property subdivision lines shown as public roads are dedicated to be in public right of way. (Revl) Comment has been acknowledged and addressed for preliminary site plan. Approved road plans are required for final site plan approval. Please submit as "Application for Review as a Subdivision Plat" and include "Public Street Fees" and $250 fee for public road plan review. Application is available here: http: / /www.albemarle.org/ upload /images /forms center /departments /Community_ Development/forms /applications/ Subdivision_ Plat _Preliminary_ &Checklist.pdf B.

Existing Conditions Information 1) Please label the apparent limits of the 100 year flood plain for Slabtown Branch on sheet 3. It appears these limits have been identified by a slashed area near the Old Trail Drive crossing. (Rev-1) Comment has been addressed. 2) Please note date of original field topographic survey on sheet 1. Please field Engineering Review Comments Page 2 of 6 verify existing topography and note as much on the plans. Existing topography must be field reviewed within one calendar year of each submittal. (Rev]) Comment has been addressed. 3) Please note the 100' stream buffer extends from the edge of all perennial streams. This applies to the unnamed creek draining to Slabtown Branch. Please update the 100' stream buffer line accordingly. (Rev]) Comment has been addressed. D. Proposed Plan View Information 1) VDOT approval is required for this project as it affects public right of way. (Rev]) Comment has been acknowledged. 2) This parcel lies in the "For Bio- Filter Facilities" part of the Old Trail Village rezoning plan per ZMA2004- 00024. Introducing biofilters to treat runoff from this block will increase the stream buffer impacts to Slabtown Branch. Please indicate proposed bio- filter and stormwater management easement locations. For impacts proposed to the stream buffer for Slabtown Branch, applicant is required to provide a mitigation plan for review and county approval. Please quantify in area the total proposed stream buffer impacts proposed with this project. Please note only the landward 50' of the buffer can be disturbed. (Rev]) Comment has been addressed for preliminary plans. Note separate WPO plans are required for final site plan approval (see top of this letter). 3) Please label Road B and Road I on sheet 4. (Rev]) Comment has been addressed. 4) 2:1 fill slopes for Road B appear to be proposed.

(Rev]) Please label all existing and proposed utility easements including sanitary sewer, water, and drainage easements with label leaders or use symbols and legends. 11) Please indicate 20' wide drainage easements for all drainage crossing proposed property lines. (Rev]) Comment remains. Because property is proposed to be subdivided, all drainage crossing proposed property lines must be included in 20' wide drainage easements. Includes the following runs (Structures 7- 6- 5- 4- 3 -2 -1, Structures 16 -15, and Structures 10 -9. End sections and scour protection will be required for Structures 12, 9, and 1. Please include these areas in proposed drainage easements. 12) Please update landscape plan to ensure no trees are proposed in conflict with drainage or sewer utility lines. (Rev]) Comment remains — policy is to prohibit planting in utility easements for potential future excavation purposes. Also, please re -skew drainage Structure 10 -9 pipe or modify landscape plan to avoid outfall conflict with proposed Patmore Ash tree. 13) Please label entrance radii. (Revl) Comment has been addressed. 14) Please label proposed parking stall width. (Rev]) Comment has been addressed. 15) Please label length of proposed on street parallel parking spaces.
