The following comments will need to be addressed before approval: VSMP Plan must be approved before final site plan can be approved. Rev. 1: Comment still valid. Rev. 2: Comment still valid. 2. The site plan must only contain what is required per Chapter 18-32.6.2 of the county code. Therefore, erosion & sediment control sheets should be removed from the final site plan. Rev. 1: Comment addressed. 3. [Section 8 Design Standards Manual] Slopes steeper than 3:1 must be permanently stabilized with landscaping vegetation hardier than grass, which will not require mowing. Ensure this is noted on the landscape plan. Eliminate any slopes steeper than 2:1. Rev. 1: Comment addressed. 4. Illustrate internal handicap access routes. Include spots to show grading meets requirements. Rev. 1: Comment addressed. 5. Clearly label the extent of flush curbing vs. CG -6 curbing. Provide a legend if necessary. Rev. 1: Comment addressed. 6. It appears that changes to the roadway are proposed with this site plan. Changes to the road must be submitted as a road plan amendment. VDOT approval is also necessary before final site plan approval. Rev. 1: Comment addressed. 7. Stream buffer is shown on plan along with improvements/grading in this buffer. Please show proposed buffer outside of all improvements. The gravel trail can be inside the buffer. Rev. 1: Why is grading so extensive (different from last submission) on the northeastern side of the site? The stream is perennial and buffer should be as close to 100 ft as possible. Rev. 2: Comment addressed. 8. Is there an easement or maintenance agreement for the 9' gravel trail? Rev. 1: Who will maintain the trail? Rev. 2: Comment addressed. 9. Provide top and bottom elevations of retaining walls on the grading plans. Rev. 1: Spots insufficient to show that walls do not exceed 6ft in height. Rev. 2: Comment addressed. 10. Please show steep slope hatching on grading/layout sheets. Ensure that design standards are followed for retaining walls in this overlay district (per 18-30.7.5). This includes landscaping with screening shrubs. Rev. 1: The managed and preserved slopes on Sheet C2.1 appear to be switched. Also, there appears to be disturbance within the preserved slopes. This is not an allowed disturbance per County Code 30.7.4. Rev. 2: Extend the pipe and outfall all the way to the water surface elevation of the pond. Should not outlet in steep slopes. 11. Label all entrances with a VDOT designation. Rev. 1: Designation is not clear (CG -9D, etc). Rev.
