Box 996 College Station, Texas 77842-9960 Re: CatHollow Subdivision Revised Construction Plans Dear Veronica, ~~- - l~ ~Y ~,- ~_ ~~ `~~S' ~C7 ~~~~ ~x Attached please find the revised construction plans for the Cat Hollow Subdivision. Your redlined set is also included. We have made the revisions shown on the redlined set hopefully to your satisfaction. In working with the utility department, we have raised the sanitary sewer along Dominik to get more clearance between the bottom of the creek and the proposed sewer line. In order to accomplish this, the sewer line has been raised on more than one sheet.. Therefore, expect to find differences on the sewer sheets other than what you have redlined. In addition, it was necessary to reroute a sewer line from Lynx to Dominik (eliminating a section of line and adding another). The necessary profiles have been done and are included on the Lynx sanitary sewer sheet. This rerouting was necessary due to the raising of the sewer. All of the plans views affected by this rerouting (including the utility plan) have been re-plotted and are included in your revised set. An enlarged detail of the sanitary sewer line crossing at the creek has been provided on the Dominik sanitary sewer line sheet. We have also added an enlarged detail for the sanitary sewer/box culvert crossing. We designed as per a meeting with the utility department. We have not provided a set to them with the revised design. If necessary for them to review, please allow them to use your set or contact me and I will provide an additional set. In addition, we had to adjust the easements on the final plat to match the rerouting of the sewer line, as Jane may have mentioned to you. The revised plat is included in your set, and ten copies of the revised plats have been submitted to Natalie. Finally, we have made two changes that were not requested per your redlined comments. The 30" RCP that enters the pond has been changed to a 3'x2' box culvert. The pipe was changed to a box for AESTHETIC REASONS ONLY. The box comes out of the ground at an uneven slope due to the angle at which it cuts across the berm. We feel that the sloped end of the box is preferable to the sloped end of a pipe. The other change is an additional note added to some of the sheets requiring the contractor to construct the manholes to match the finished grade, not natural ground. We trust the above submitted plans have been revised sufficiently. If not, please contact me at your earliest convenience so that we may resolve any differences remaining. Sincerely, Deborah L. Keating, P.E. ~~~~~~ : ~ ~ ~~ Urban Design Group c:\winword\glenh\v4.doc Post Office Box 10153 College Station, Texas 77842 409 • 69 6 • 9653 Qu a~~ CAT HOLLOW REVIEW. 1.
