Re: Drainage Certification for Lot29, Block 10, FossiLLake_P_UD; First-Filing�-
Dear Lisa,
We recently performed an as -built survey for the above -referenced lot,(3265_Rookery Road),to
verify whether its grading met the approved grading and drainage plan- Spot elevations were
checked at pertinent locations and compared to the grading plan. The enclosed drawing shows
these as -built elevations.
In general, the lot and building meet the requirements of the grading and drainage plan and
there is positive drainage away from the building on all sides. The final grade adjacent to the
garage is 4908.4; the garage floor elevation is 4908.45. The final grade around the remainder
of the house ranges from 4908.2 to 4910.1; which is sufficiently below the first floor elevation of
4912.3.
The intended drainage patterns are met by the grading on this lot: the grading for the lot
provides for positive drainage away from the house, but also allows the back yard to drain north
to Rookery Road as shown on the grading plan.
It is our recommendation that the CO for Lot 29, Block 10 be released since the Builder graded
the lot to meet design drainage pattems- If you have any questions, please call.
Sincerely,
Owen Ayres &
