Engineering review can recommend approval to the plan after the following comments have been addressed. 1. In the applicant's letter dated 2 October 2009, waivers from Chapter 18 -32 were requested. The following comment is engineering review's analysis of the waiver requests. 32.5.6.d Topography The applicant must shade all critical slopes. By looking over the more accurate topography provided by the applicant, it is clear that critical slopes exist on the property. Disturbance of critical slopes for the driveway will be considered exempt per 18- 4.2.6.c. Engineering review has no objection to the waiving of the 50ft off the boundary requirement for topographic information. 32.5.6.n Waiver of the lighting and landscape requirements of this section Engineering has no objection to the waiver of these requirements. Engineering will note that it appears as though 2 significant trees will be removed due to the current design of the site. 32.5.6.q Traffic Generation figures The location of this development is not pertinent to this requirement. The applicant must note on the plan that the site generates 75 trip ends and that the distribution is evenly divided between the north and south on Crozet Ave. (This number was determined from ITE's Clinic section, 630, since there was no section provided for a veterinarian's office.) 2. After further review of the application, it appears several other sections of the Chapter 32 must be waived. Below is a list of requirements in 32.5.6 and 32.6.6 that were not provided in this plan and engineering commentary on each section. 32.5.6.a General Requirements (SP Conditions and Datum) The plan should list the conditions of the Special Use Permit on the sheet. Also, the County's ordinance requires that for properties in the vicinity of a FEMA floodplain the USGS datum must be used. Engineering review requires further information regarding the NGS Y -55 datum and how it relates to the FEMA floodplain datum before a recommendation can be provided. Albemarle County Community Development Engineering Review Comments Page 2 of 3 32.5.6.g Stream Buffers The stream buffer line should be shown on the plan. The stream immediately behind the building requires a buffer. Disturbance to the stream buffer will be allowed under 17 -321, but a mitigation plan will be required. 32.5.6.1 Location of existing and proposed utilities and utility easements. Please show the drainage pipe that will be constructed with the Downtown Crozet Stormwater Management project. Please show the drainage easements for the pipe at the front of the property and the channel at the rear of the building. Please also clearly note on the plan that the pipe is not to be included in the development of this application. 32.5.6.m Distance to centerline of nearest existing street Engineering review has no objection to the waiver of this requirement. The location of the entrance has been set by the Board of Supervisors. 32.5.6.p Landscape Plan Engineering review has no objection to the waiver of this requirement. Engineering will note that it appears as though 2 significant trees will be removed due to the current design of the site. 32.6.6.d Drainage plans (Profile) Engineering review has no objection to the waiver of the drainage profile (32.6.6.d.2) and the drainage schedule (32.6.6.d.4) requirements. Though, engineering recommends that a profile be provided so that an adequate cover of the pipe is accounted for to prevent reconstruction in the future. 32.6.6.g Parking and Loading Space dimensions The parking spaces should be delineated on the plan and dimensioned to make sure they meet county requirements. Engineering review does not recommend that this section be waived. 32.6.6.i Final Landscape Plan Engineering review has no objection to the waiver of this requirement. Engineering will note that it appears as though 2 significant trees will be removed due to the current design of the site. 32.6.6.j Final Photometric Plan Engineering review has no objection to the waiver of this requirement. 3. The applicant's letter alludes to the travelway not being constructed with this project. If not with this project, when will the travelway be constructed? I recommend that this project construct the travelway so that no delays to the occupation of the building will be encountered due to delays in other project timelines. 4. A mitigation plan must be approved before the site plan can be signed. 5. An ESC plan will be needed for this project. 6. This project is exempt from detention requirements per 17- 314.17.4. Water quality requirements will be met with a fee to the Lickinghole Basin. This computation will be performed at a later date. Albemarle County Community Development Engineering Review Comments Page 3 of 3 7. The existing gravel drive should be removed. If it is to remain, landscaping or other obstacles should be provided around the parking lot to prevent use of this second entrance. The removal of the gravel would help reduce the Lickinghole Basin fee for this project. 8. The applicant has requested a waiver of curbing requirements for the parking lot and travelway. Because the absence of curbing is not for stormwater management, the Zoning Administrator will need to make the decision on the waiver. Engineering review has no objection to the granting of this waiver except on the west side of the parking lot. I think curbing should be provided on this side of the lot to keep as much water as possible away from the foundation of the building. 9. The travelway must be 20ft wide. [32- 4.12.17.c.1] 10. Please update the entrance profile. The profile of the entrance does not match the contours as drawn. The entrance should also be adjusted in a manner that provides an adequate landing for stopped vehicles at the entrance. [32- 4.12.17.b] 11. The slope of the travelway does not meet the County Ordinance requirements. The grade of this travelway is shown as 20% and the maximum grade allowed by the county is 10 %. If a waiver is sought, please provide this request in writing with all information necessary to justify that no reasonable design alternative exists. It looks as though the maximum grade can be met if the entrance is snaked to the northern entrance to the parking lot. Zoning will need to determine if this change is a significant deviation from the approved application plan. [32- 4.12.17.a] 12. Engineering review suggests that the applicant consider running the sanitary sewer lateral to one of the two manholes south of the building, if allowed by ACSA. This will eliminate the stream crossing and tapping into a clay pipe, which may be problematic. If the stream crossing is to remain, please coordinate the design of this pipe with the Water Resources Division of Albemarle County to make sure the pipe is accounted for in the new design of the stream channel. 13. Please remove the note about the outdoor exercise area per condition 5 of the approved SP. 14. Please provide a few spot elevations in the corners of the parking lot to show that the grading is no greater than 5% in any direction. 15. Please provide low maintenance, non - grassed groundcover on the slopes adjacent to the travelway or flatten out the slope to 3:1. Acceptable groundcovers can be found in table 3.37C of the VESCH, though other landscaping can be satisfactory. [DM] 16. Please show all critical slopes on the plan. [18- 32.5.6.d] 17. Please provide no parking signs in the turnaround area at the northside of the parking lot. [18- 32.7.2]
