We felt that all of the critical slopes were part of either a previously approved site plan or were already approved to be disturbed for White House so we did not include a critical slopes waiver. -I understand that if after further review we discover that one is required that we will not be on the PC schedule based on our submittal date as the waiver was not requested with the submittal on Monday. There were two separate 11x17's that we copied from the approved plans we had on file that were attached with the submittal Monday. :I couldn't actually find the Free Bridge Site Plan SDP# (its too old) but we did find -the SP# which I suspect will lead you to the siteplan - file.. Again if you have any questions please contact John or Myself. Thanks! - Justin .From: John Dawson '[mailto:jdawson @ddrva.coni] ,Sent: Thursday, September 17, 20091:56 PM To: 'Justin Shimp' :Subject: Free Bridge John Dawson Dominion Engineering CAD Operator- 172 South Pantops Drive Charlottesville, VA 22911 tel : 434.979.8121 W. jdawson @ddrva.com fax: 434.979.1681 Always have my latest info Want a signature like this? 9/18/2009 v5 0<5 Dominion iEngineerinq .& Design,LLC le,s September 14,2009 Mrs. Elizabeth Marotta Senior Planner Albemarle County Community Development 401 McIntire Road Charlottesville, VA 22902 Re: Free Bridge Office (SDP200900062) TMP 78 -11 Design Review Comments: Preliminary Site Plan Dear Elizabeth, 172 South Pantops Drive Charlottesville, VA.22911 Phone: 434 - 979 -8121 Fax: 434 - 979 =1681 DDRVA.com We have revised the plans for the subject site based on the County's letter dated September 1, 2009. A response to each comment follows (previously addressed comments have been omitted): 1. [32.5.6b] COMMENT: It appears that 53 spaces are provided, whereas the Site Data list indicates 48 spaces are provided. Please address this discrepancy. The Site. Data list has been updated to show 53 spaces. 2. [32.5.6d] COMMENTS: Critical slopes- UPDATE: Provide evidence that critical slopes were created with an approved site plan, otherwise a critical slopes waiver will be required. Also, please provide callouts or legend to identify the shading on the existing conditions plan (that I believe to be critical slopes). All critical slopes on the parcel are either man -made or approved for disturbance by an adjacent .site development plan. The existing conditions sheet has been modified to provide detail.about which slopes were created by an approved plan. Copies of the approved grading-sheets have been provided. Topography- It is required that you show topography and features at least up to 50' outside the property lines; please revise accordingly. Also, it is my understanding that (some of) the topography shown on the existing conditions plan is not actually existing, but is per an approved site plan (particularly off - site topo). Please be very clear about what topo is existing, and what topo is per an approved site plan. Where applicable, identify which site plan the approved topo came from. 'The plan has .been revised to show 50' of offsite .grading .and topography. A legend has been .provided -to -show which existing contours are from proposed -site development plans and which ,.are-existing conditions. Offsite topography- Because off -site grading is proposed, please show beyond the limits of all disturbance.. 'The plan now shows topography 50' beyond the limits of all disturbance. topography for at least 50' Confidential Page 1 9/17/2009 Comment Response Letter Marotta9= 14- 09.doc 3. [32.5.6n] COMMENTS: Parking lots- UPDATE: Required parking spaces are being provided off -site (23 +/- spaces)..An offsite parking agreement is required to be submitted and approved prior to final site plan approval. Prior to preliminary site plan approval, provide evidence the adjacent property owner is willing to provide /negotiate the required agreement(s). Inter - parcel connectivity- This site is subject to Sec. 32.7.2.5 and inter - parcel connectivity is required. The adjacent Kia major amendment plan (SDP200500135) provides a connection point to this property, as does the preliminary plan for Whitehouse (SDP200800020, Final SDP200800124) Please revise the plan as necessary to provide inter - parcel connections. Interparcel connection -for the Whitehouse commercial site has been provided to the Tip -Top restaurant parcel. We believe that the connection to the U.S. Route -250 sites is of greater importance than parallel to Olympia Drive. Given the grade constraints between the -two parcels it is also the most practical. Concerning the Kia connection, we again find that designing the Free Bridge Office site in .a manor that connects to Parcel .57B on the .U.S .250 side is a .better interparcel connection and that encouraging vehicular traffic away from .250 while encouraging pedestrian movement between sites along Olympia Drive is preferred. Given the proposed use of the Kia site, as a display lot and service area, we do not want to encourage through traffic from the adjacent office building in front of the service bays for Kia. Signs- UPDATE: Signage is not required to be shown on the site plan. Comment noted, 4. [32.5.6j] COMMENT: Albemarle County approved an easement plat on 11/ 21/08 that shows the drainage easement on the subject parcel as remaining, and in fact provides a new easement segment. The proposed preliminary site plan shows this easement as `to be vacated' and relocated to the western property line. Please address this discrepancy, and update the preliminary site plan to show all existing easements. Based on the plats that we have prepared we believe that we are showing current easements as recorded if you believe there still is a discrepancy please provide additional detail on the plat referenced in your comments and we will further investigate. 5. [32.5.6.e] [32.7.9.4.c] COMMENT: Existing landscape features are required to be shown. If none exist, please provide note on plan to confirm there are none to show. Existing landscape features are shown on the existing conditions and demo plan on sheet C3. Final tentative approval from this department will be subject to the following conditions: [These conditions are those which have been identified at this time. Conditions may be added or eliminated based on additional review.] These comments will be addressed during Final Site Plan submittal. 1. [32.5.6n] UPDATE: Offsite parking agreement is required to be submitted and approved prior to final site plan approval. 2. ARB approval is required prior to final site plan approval. 3. [32.7.9.6 Street Trees] Prior to final site plan approval, the requirements of this section must be met. I hope that this satisfactorily addresses all of your concerns. Please let me know if you have any questions or additional concerns. Thank you.

A response to each comment follows (previously addressed comments have been omitted): A. Preliminary Site Plan Comments: -1. Please provide removal rates for the pre - development and post - development drainage areas. Simple 4.calculations have been included with this submittal. 2. Please provide for interparcel connectivity to the neighboring parcels as shown on the approved Whitehouse Commercial Preliminary Site Plan (SDP20080020) and the Kia Site Plan Major Amendment (SDP200500135). Interparcel .connection for -the Whitehouse commercial site has been provided 10 the Tip-Top restaurant parcel. We .believe that the connection to -the .U.S. Route _250 sites is of greater importance than parallel to Olympia Drive.

Given the proposed use.of -the -Kia site,.as a display lot and service area, we do not want to encourage through -traffic from the :adjacent office building in front of the service bays for Kia. 3. Please designate which critical slopes (as shown on the Existing Conditions Plan) are man -made, and designate the approved plan which created them - Olympia Drive, Kia, or Free Bridge Auto (application numbers and approval dates can be researched at the Community Development Offic or on -line at Countyview Web). Designate which critical slopes, if any, are natural. The disturbance of critical slopes which were not created with an approved plan will require a waiver from the Planning Commission. All critical slopes on the parcel are man -made. Copies of the approved site plan grading have been provided. 4. To provide safe circulation, it is recommended that the entrance to the lower parking lot be moved farther away from Olympia Drive. A minimum tangent of 50 -feet between the two entrances is suggested. Comment noted, given the site constraints the recommended 50' tangent could not be obtained. Confidential Page 1 9/17/2009 Comment Response Letter Diez9- 14- 09.doc 5. Based on the 2.5:1 slope and the greater than 10 -foot drop -off, it appears that guardrail is necessary in front of the 5 proposed parking spaces in the Free Bridge Auto lot. [DM] Guardrail has been provided along the_5 proposed parking spaces. 6. The difference in grade created between the proposed travelway and the Whitehouse Commercial site could require a guardrail on the Whitehouse site. [DM] Comment Noted. 7. The difference in grade created between the proposed parking lot and the existing Free Bridge Auto site could require a guardrail along the existing Auto parking . [DM] Currently.safety rail is.being provided along the retaining wall.between Free Bridge Auto existing parking and proposed parking. During Final.Site Plan submittal if guardrail is deemed necessary it will -be provided. .B. Final Site Plan Comments (For information purposes only): 'These Comments will be addressed at Final Site Plan Submittal. 8. Vehicle access aisles, that are not adjacent to parking spaces, shall not exceed a grade of 10 %. [18- 4.12.17a] 9. Dumpster pad cannot have drainage running beneath it. The site must be designed so that stormwater does not run through, and drains away. 10. VDOT approval must be obtained for plans that affect right -of -way prior to final site plan approval. [DSM902B] 11. A temporary grading and construction easement will be necessary from the Whitehouse Commercial parcel prior to approval of the Final Site Plan. Please provide a letter of intent to grant the easement from the owner of this parcel. -12. The boundary line adjustment and easement plats necessary to accommodate this development must be recorded prior to approval of a Final Site Plan. 13. The final site plan is subject to County Code Chapter 17 Water Protection Ordinance. Approval of a Water Protection Ordinance Application including Erosion and Sediment Control Plans per Article II will be required. To ensure that Stormwater Management and Water Quality was accounted for with the design of the Luxor Pond, please submit the allowable impervious area (or C- value) of the site, based on the Luxor Pond plans, and the actual proposed impervious area. I hope that this satisfactorily addresses all of your concerns. Please let me know if you have any questions or additional concerns. Thank you.
