December 2008 have received Engineering review. The plans may be approved after the

7. REV 1: Proposed grading is difficult to see on Sheet S -3 Grading Plan. It does not
appear that the proposed alley grades are tied in to existing contours. The proposed
trail contours are incorrectly tied to existing.
C. Erosion & Sediment Control Plan Comments:
8. Please include design and calculations for all erosion and sediment control structures.
The two basins in the rear of the property must be constructed with this project for the
stormwater system to work.
REV l: Details and calculations for Sediment Basins I and 2 are on Sheets ESC -4
and 5, but this information has not been provided for Sediment Basins 3 and 4.
9. REV 1: Will the "drainage ditch" installed in Step 5 of the Sequence of
Construction be removed prior to Phase II of the Plan? Phase II involves the
installation of the 42" storm sewer pipe. The fill required to install sections 60 and
62 of this pipe will "dam up" the natural channel that this drainage ditch releases
to, cutting off its flow to Sediment Basin 3.
D. Stormwater Management Plan Comments:
10. Please show Stormwater management easements encompassing all structures, access
easements and 100 -year high water mark/level
REV 1: Comment has been addressed.
11. A completed copy of the standard stormwater maintenance agreement and fee for
recordation for the stormwater facility is required prior to final approval.[17 -304E] The
forms and instructions can be found on the County Web site:

Drainage Basin prior to final approval. [17 -316]

Project Limits as shown on Sheet E -l.
