Plat -
4. The plat should be on 2 pages, increase the size to be more legible.
5. There is no need for the drainage/detention easements.
6. All public fire hydrants and vaults should be in an easement.

8. There will need to be a sidewalk/utility easement along Denton Tap Rd.
Pavine Plan -
9. Typical pavement section should be 3600 psi. Is the pavement lime stabilized? If not, a letter

21. A Property owner's agreement will be need for maintenance of water and storm.
22. Do not tie the sanitary sewer to Lewisville's 27" line; use the 12" Coppell system. You

23. Show the easement on the plan sheet, the easement should follow the line to the next
property.
