Re: SUB-2016-00065 Greenloft Farm — Road Plan
Dear Mr. WentIand,
We have reviewed the Greenloft Farm Road Plan, dated March 24, 2016, as submitted by Collins
Engineering and we offer the following comments:
1. On sheet 3, a landing having a minimum length of50' and a maximum vertical grade of
2% should be provided and should begin at the edge of pavement of Route 706.
Additionally, the minimum K value of sag curves based on a design speed of 25 mph
should be 26. The vertical curve between station 10+25 and 11+00 should be revised
accordingly.
2. It appears that a Drainage Inlet will be needed at the proposed entrance, across from
structure #16, to convey runoff from the ditch along Greenloft Farm Court, through the
proposed pipes along Route 706.
3. Please provide calculations for the sight distance for the vertical curve between station
10+25 and 11+00, in accordance with AASHTO GDHS, Chapter 3.
4. Left turn and right turn lane warrants should be provided.
5. The posted speed on Route 706 is 45 mph. Please provide sight lines and profile that
meet the 45 mph standards. "Intersection Sight Distance Details" can be found in
Appendix A of the Road Design Manual.
If you need additional information concerning this project, please feel free to contact me.
