Re:. Drainage Certification for Lot 4, Block 3, Fossil Lake PUD, First Filing
Dear Lisa,
We recently performed an as -built survey for the above -referenced lot (3215 Twin Wash
Square) 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 first floor elevation is
4915.23, which is 0.27 feet higher.than the design elevation of 4914.96. The final grade around
the house ranges from 4912.1 to 4912.8, which is consistently lower than the design finished
grade of 4913.3.
The grading for the lot provides for positive drainage away from the house. It appears that there
are no irregularities in the grading of the drainage channel (no humps or low spots).
It is our -recommendation that the CO for Lot 4, Block 3 be released since the Builder graded the
lot to meet design drainage patterns. If you have any questions, please call.
Sincerely,
Owen Ayres &
