From: Daniel Heischman, P.E. Co: City of Lewisville- Eng. Dept. Date: March 4, 2005 Address: 151 West Church Street CC: Keith Marvin Lewisville, Texas 75057 File Phone: 972-219-3460 Via: Hand Delivery Re: Villas at Lake Vista Job #: 03067B Coppall, Texas Attached, please find the following: 1 Set of Construction Plans 1 Aerial Exhibit 1 Lake Vista Ddve Cross-sections 1 Landscape Plans Mr. Kumar; The following plans reflect the additional information you requested. The changes/additions are: · Notes added to final plat · Separate sheet showing Lake Vista Ddve cross-sections · Plate 8C showing Lake Vista Ddve gutter capacity calculations · Additional aerial in conjuction with the Lake Vista Drive sheet to show entry ddve relationship to existing ddves on opposite side of road · Landscape plans showing buffer, screening wall & plantings Please accept this additional information for your review. I do want to point out that in our street capacity calculations for Lake Vista, our 100 year flow exceeds the single lane (12') required to leave "dry" (one side of 48' street) by 0.4' which is less than a tenth of an inch in depth. If required, we will install an inlet to pick up this water, but hope the City of Lewisville accepts our design to leave 11.6' open for a dry lane. Please feel free to contact me on any of the above issues. Thanks, Daniel Heischman, P.E. Received by: Date received: [jOWDEY, ANDERSON & ASSOCIATES, INC.
