Arbor Manors-CS070104 DEVELOPMENT REVIEW COMMITTEE ENGINEERING COMMENTS ITEM: (Public Hearine) PD-214R-TH-l, TH-2. C and SF-9. The ElIineton, zoning change request from C (Commercial), R (Retail) and SF-9 (Single Family-9) to PD-214R-TH-l, TH-2, C and SF-9 (Planned Development- 214 Revised-Townhouse-l, Townhouse-2, Commercial and Single-Family), with a Concept Site Plan to allow the development of 125 townhouse units (67 TH-l units on approximately 12 acres of Tract Al and 58 TH-2 units on approximately 8 acres of Tract A2); Commercial uses on Tract A3 (approximately 2 acres) along Sandy Lake Road and on Tracts AA and A5 (3.8 acres) along Denton Tap Road; SF-9 on 3.3 acres for park/open space on Tract B for a total of approximately 29.05 acres of property located south of Sandy Lake Road, and west of Denton Tap Road STAFF REP.: Garv Sieb PROJECT ID# PD-06-00n DRC DA TE: December28, 2006 and January 4, 2007 CONTACT: Kenneth M. Griffin, P.E., Dir.ofEnl!ineerinl!/Public Works 972/304-3686 COMMENT STATUS: PRELIAfll\TARY ./FINAL REVISED l'~rTER P&Z Concept Plan 1. There needs to be discussion on whether or not the required parking will be allowed within the right-of-way or relocated outside the right-of-way. This will impact the location of the sidewalk, which may require easements around the parking areas. 2. Has A TMOS been approached about relocating the existing 50 foot Lone Star Gas easement and are they amenable to the crossing of the easement with a trail? 3. TXU has submitted Work Order #2821838 to install overhead electric lines through this development. The lines themselves are all along Sandy Lake Road cutting through this development, then crossing Denton Tap Rd., and continuing through the intersection of Moore/Sandy Lake. The portions of the lines that cross this site will impact Lots 20, 21, 23- 28, Block A; Lots 5-6 and 8-14, Block E; and Lot 9, Block D. I would recommend that you contact Richard Brewster with TXU at 214/486-4245 to discuss the TXU lines. I have also noted on the permit approval for TXU that they should contact you concerning that project. Drainage Plan 4. The Wynnpage Subdivision to the south shows a 36" RCP stubbed out to pickup water from a portion of this proposed development. That 36" RCP is located where the trail will be extended. Therefore, there will need to be some modification to the headwall of the 36" RCP to insure it works with the trail configuration. Additional comments may be generated upon detailed engineering review.
