RE: The Meadows at Legacy, Section 2- Project Review #1
Dear Mr. Huff:
The City received your construction plans on May 17, 2013. The project was scheduled for review at the
June 19, 2013 Technical Advisory Committee meeting. We offer the following comments:
CONSTRUCTION DRAWING REVIEW COMMENTS
1. MFPG on Sheet 1 of the Final Plat is defined as Minimum Finished Pad Grade. Is this
correct?
2. Is L.C.A #4 being platted as a drainage easement?
1 Please provide the legal description on the construction plans.
4. Please provide the locations of all electrical power vaults, transformers, power lines, gas
lines, television cable, and telephone lines,
5. Please provide all existing easements, onsite and adjacent to the site on the Topographic
Survey and Site Development Plan, in order for the Department to evaluate easement widths
and/or conflicts.
6. Please indicate the Iimits of the Duke Energy easement on the Site Development Plan.
7. Is the existing DD #1 located within a platted drainage easement?
8. Please indicate all offsite improvements (curbs, sidewalk, pavement, and pedestrian path) in
order for the Department to evaluate continuity.
9. Are all lots adjacent to side yard easements wide enough to accommodate the anticipated
house and any planned driveways such that there is no encroachment into the easements?
Driveway encroachments will not be allowed within easements.
10. All swales shall be contained within a 30 -foot drainage easement.
II. A drainage easement is required for the swale at the back corner of Lot 38.
12. Is a pedestrian facility planned between Lots 42 and 43? If so, what type of pedestrian
facility is planned? Please indicate on the Site Development Plan. Will it connect to an
existing pedestrian facility?
13. Please differentiate between the MFPG/MLAG for the front and back of each lot within the
legend on the Site Development Plan.
14. What are the MFPG and MLAG based on? These elevations shall be based on:
a. 1 -foot above the maximum water surface elevation onsite, during a 100 -year rain event,
assuming all storm inlets plugged.
b. 2 -feet above the i 00 -year elevation of the detention facility and 2 -feet above the
emergency spillway.
c. 2 -feet above the flood route from the pond (the proposed temporary swale to DD #1).
15. On the Site Development PIan, please refer to Figure 11 for the pond cross section and
details.
16. There appears to be a direct discharge at the southwest comer of the project.
17. Does the temporary Swale, conveying drainage from the detention basin outlet, meet all City
standards?

18. What is the status of the existing DD #I? Does it meet City standards? Are there as- builts for
this area?
19. Please label the location of the emergency spillway detail, and ensure the contours represent
the proposed grading of the spillway.
20. Please label the Top of Bank elevation for Detention Basin #7 on 0200.
21. It appears that the top of bank for Detention Basin #7 is 754.3, which would be located on the

portion of a detention facility can be located on a residential lot.
22. Please provide the flood routing from Detention Basin #7 to the nearest receiving system.
23. Please label the 25 foot required building setback from the detention facility on each
individual residential lot.
