Addendum 1 & 2 of Original Drainage Report
. ' I 11 I I I I I I I Edelweiss Gartens Subdivision Phases 2, 3 and 4 Addendum to the Original Drainage Report submitted in conjunction with the Phase 2 Construction Drawings September 23, 2002 f I I I I I I I I I ADDENDUM OF THE DRAINAGE REPORT FOR EDELWEISS GARTENS SUBDIVISION The changes being proposed to Edelweiss Gartens Subdivision do not affect the overall hydrologic and hydraulic characteristics from the original report. The total drainage area and runoff rates remain the same. The detention pond that was designed and constructed with Phase 1 is still adequate to serve the entire development. The only changes to the system involve sizing and alignment of the underground storm drain system and the capture of offsite runoff that must pass through the subdivision. As with the original system, the revised storm drain system is designed for a 10-yr storm event as required by the City of College Station. The following exhibits are provided to show the revisions to the drainage system.

Laza, Registered Professional Engineer No. 65923, State of Texas, certify that this report for the drainage design for the EDEL WEISS GARTENS SUBDIVISION, PHASES 2, 3 AND 4 project Addendum# 2, was prepared by me in accordance with the provisions of the City of College Station Drainage Policy and Design Standards for the owners thereof DRAINAGE REPORT ADDENDUM #2 OF THE DRAINAGE REPORT FOR EDEL WEISS GARTENS SUBDIVISION During the design of Phases 3 and 4 of Edelweiss Gartens, it became apparent that the initial drainage system design needed modification to increase efficiencies in the pipe routing and minimize earthwork requirements. The modifications involved the realignment of a storm sewer, removal of concrete flume, and the addition of several inlets. These modifications do not affect the subdivision's overall hydrology or hydraulic design, but they require changes to the drainage area map, the line sizing spreadsheets and the hydraulic grade line calculations. Those changes are reflected on the following exhibits: Exhibit B -Revised Drainage Area Map Exhibit C-1 -Drainage Area Calculations Exhibit C-2 -Inlet Computations Exhibit C-3 -Pipe Size Calculations Exhibit D-1 -Hydraulic Grade Line Calculations Exhibit D-2 -Hydraulic Grade Line Profiles ADDENDUM TO DRAINAGE, WATER AND SEWER REPORTS EDEL WEISS GARTENS SUBDIVISION EXHIBIT C-1 Rational Formula Drainage Area Calculations EDELWEISS GARTENS PHASE 2,3, & 4 NO.
