Review Comments for the Final Plat and Engineering
Plans for the Pecan Hollow Addition
FINAL PLAT:
Add variance request for a minimum depth of less than 4' for
the sanitary sewer main serving Lots 1, 2, and 3 of Block B.
Public Works/Engineering wishes to review the proposed
Homeowners Association documents prior to City Council
consideration of the Final Plat.
PAVING PLANS:
Sheet 6/22 uses vertical curves at Station 3+50 and Station

edge of the existing Lodge Road concrete pavement be removed
to allow for lime stabilization of the subgrade in this
area. This will help to eliminate a weak joint caused by
the previous exposure of the edge of the existing pavement
to the elements. This will apply to the entire frontage of
the Owner's property along Lodge Road.
