The subject short plat drawings have been reviewed but cannot be completed until the following items
have been addressed/corrected. Once the corrections have been made, please resubmit two set of
drawings for review.
Sheet 1
1.Specify which drain pipes go to the wetland.
2.Provide design drawing and calculations on the proposed wall. Based on elevations the wall exceeds 6.
Also, since portions of the wall exceed 8, the drawings and calculations will have to be sent out for peer
review.
3.What type of wall is being installed?
4.Is there sufficient cover over the sewer pipe for the placement of the wall?
5.Why not place the sewer line on the north side of the wall for easier access
6.There appears to be a grade conflict between the side sewer and the detention system.
7.What is the size of the rip rap pad? Add a trash rack at the end of the pipe.
8.How much area does the 4 intake pipe on the south side collect? Is it large enough? How will it keep
from getting clogged up?
9.Connect a wetland overflow stand pipe on the end of the 12 pipe located at the n.w. corner of the lot.
Provide construction details on the overflow pipe and the overflow elevation to insure the wetland
remains at the level as determined by Pentec or your wetland biologist.
10.Show the locations of the pipe anchors with spacing.
11.Show location and type of hill holders since the slope exceeds 20%.
12.The minimum depth of sewer manhole #2 needs to be 4 and a concentric cone is required. Placement of
the concentric cone should allow easy access to the center channel
