I • May27, 1998 Mr. Paul Casper Graduate Engineer City of College Station P.O . Box 9960 College Station, TX 77842-9960 RE: Edelweiss Estates Phase 7-C Drainage Addendum. Dear Steve : The "Storm Drainage Analysis for EDELWEISS ESTATES PHASES ONE THROUGH SIX" dated October, 1996 and revised January, 1997 is appropriate for Edelweiss Estates Phase 7-C with the following modifications. The street layout for Phases 7-A and 7-C have changed compared to the layout of the original report . 1bese changes required the redesign and placement of additional in lets to efficiently capture the storm water runoff. Also, with the detailed design process, it has been determined that some additional inlets are required along Edelweiss Avenue. This in part is due to the fact that two of the future streets intersecting Edelweiss Avenue will not be low point intersections. The revised Drainage Area Map, Exhibit "B-1" is enclosed with this letter. These changes are reflected on the Exhibits ''C-1 ", "C-2" and "C-3" enclosed with this letter. The drainage areas affecte<l by this change are shown in red on the tabular exhibits. Please attach these two (2) sets of the ex hibits to your current copy of the above referenced "Storm Drainage Analysis for EDEL WEISS ESTA TI~S PHASES ONE THROUGH SIX ". A compk1:e report will be submitted at the time that all future phases of Edelweiss Estates south of Rock Prairie Road have been designed.
