Box 9960 College Station, Texas 77842 Re: Edelweiss Gartens Subdivision -Revised Master Preliminary Plat Dear Brett: Accompanying this letter is the revised Master Preliminary Plat for Edelweiss Gartens. Also enclosed are our responses to the staff comments regarding the plat, an addendum to the water and sewer reports for the subdivision, and a support document from the original submittal. We believe we have addressed all of the city requirements for the revised plat and we request to be placed on the agenda for the next Planning and Zoning Commission meeting. Thank you. Sincerely, l~Elr Project Manager 1008 Woodcreek Drive, Suite 103 • College Station, Texas 77845 (979) 693-3838 • FAX (979) 693-2554 •email: mcclure@tca.net Reply to Staff Comments for Edelweiss Gartens Amended Master Preliminary Plat 1. Please show street extension off Graham Road on plat. This entrance is a requirement of the rezoning. If property is under separate ownership, include owner on Final Plat. This change has been made to the Master Preliminary Plat (MPP). 2. Do not include "Future SH 40 ROW' in platted area unless dedication is proposed or shown reserve tract. This note has been deleted. The area will be reserved by the developer. 3. Show required hydrants on Oldenburg Lane. Hydrants have been added to Oldenburg Lane in the approximate locations where they will be built in that phase. That section of the subdivision is currently being designed and the hydrant locations may vary somewhat. 4. It does not appear a 6" water line will be sufficient for the entire length of Oldenburg Lane with required hydrants unless looped back to main. A revised model of the water system has been prepared and included with this submittal. In it, the water line on Oldenburg Lane has been changed to an 8 " line. The report demonstrates that this 8" line is sufficient to serve anticipated development along Oldenburg Lane even without the future loop that is planned in subsequent phases. 5. Lots 64-66, Block III do not appear to meet the 70-ft, R-2 requirement, as measured at setback. A note on the plat will be required stating "Parking to be provided in side yard or in rear" if this is the case. See Zoning Ordinace, Table A, Note E. A note to this effect has been added to the MP P. 6. Please show 24" W/L in easement along rear of Block 9 lots. The 24 " water line easement was placed outside of the lots in accordance with a memo from Spencer Thompson to the Planning and Zoning Commission dated May 14, 2001 when the original Preliminary Plat was being considered. The memo states "The new water line should be in the future TXDOT ROW along the back of the lots in Block 7. " (A copy of that memo is attached.) It is the developer's preference to leave the easement in the future TXDOT ROW to avoid construction in the backyards of the lots where many obstructions could be encountered. 7. What zoning district boundary goes through Lot 7, Block 9 and Lot 4 7, Block 8? Label. The zoning district boundary does not go through Lot 7, Block 9 or Lot 47, Block 8. It terminates at the northern property line of Edelweiss Gartens. This was the city limit line when the zoning for this area was approved. The Zoning District Boundary shown on the plat divides M-1 on its west and M-2 on its east. Each is labeled accordingly. 8. Show Lot to NE, 1.2879 acres, as M-1. This change has been made to the MP P. 9. An Engineer Report has not demonstrated that the 8" sewer line from Westfield Phase 3 can gravity sewer the entire Edelweiss Subdivision. An approval of this Preliminary Plat cannot be supported without documentation of this matter. The last study performed for this area show a different scenario and limited capacity. Accompanying this submittal is an addendum to the original sewer report that analyzes the sewer systems in Edelweiss Gartens and Westfield Addition. It demonstrates that the existing and proposed systems will adequately serve both subdivisions under the land use scenario shown on the MP P. 10. Take 8" water along Brandenburg through to adjacent property. Adjust OP request if needed. This change has been made to the MPP. A request for oversize participation on this line is not anticipated. 11. Take sewer to adjacent property if required Engineering Report show excess capacity. The proposed sewer system for Edelweiss Gartens contains a separate system for the southern third of the subdivision that does not utilize the current outfall through Westfield Addition. The original sewer report and the addendum that accompanies this submittal both account for about 63 acres south of the subdivision that will eventually connect to it. A future stub out to that tract has been shown on the MP P between Phases 5 and 6 12. Show all lot widths were they vary from the "norm" shown. This change has been made to the MP P. 13. Gas line crossing Brandenburg shall be a perpendicular crossing. The gas line crossing on the MP P has been changed to indicate a perpendicular crossing, but the design of that line is not within the developer's control. The gas company will prepare the design that ultimately dictates this alignment. 14. Show fire hydrant on Baden Court more toward Victoria but still meeting 500' limit. The fire hydrant has been moved to the mid-block area of Baden court on the MP P. The final location of the hydrant will be determined when that phase of the subdivision is developed. 15. Rename Karten Loop from Lots 1 thru 12, Block 8 and Karten Court, Lots 1 thru 23, Block 11. This change has been made to the MP P. 16. Rename Karten Loop, Lots 13-29, Block 8. Lots 30-40, Block 8 will be considered Karten Lane. This change has been made to the MP P. 17: 01 From: Susan Hazlett 979-764-3896 Page 2 of 11 .. MEMORANDUM May 14, 2001 TO: Planning and Zoning Commission FROM: Spencer Thompson/ DevServ, Engineering SUBJECT: PRELIMINARY PLAT for EDELWEISS GARTENS (BELLA V/STA)(PP) Item: Discussion and possible action on a PRELIMINARY PLAT for EDELWEISS GARTENS (BELLA V/STA)(PP), consisting of 386 residential lots on 86 acres, south of Graham Road and east of Wellborn Road . (1-500104) Applicant: Mr. Steve Arden Staff Recommendations: Staff recommends approval with conditions, as follows: 1. The developer must show adequate access, free and clear, before a Final Plat is submitted. 2. The developer agrees to take water service from the point dictated by the City, beinQ Graham Road at Wellborn Road. 3. The developer receives final approval from the Parks Board before a Final Plat is submitted. 4. The Preliminary Plat show the correct zoning class for each lot. Item Summary: This item is a Preliminary Plat for the Edelweiss Gartens Subdivision. The Developer will construct a collector street from Graham Road to the south through the subdivision, a portion of Victoria Street through the property to the south, and an additional east- west collector connecting the two. A Master Development Plan and Rezoning request were approved by the Commission on March 1, 2001 . The Rezoning request was approved bye~ Council on March 8, 2001. The A-0 zoned property was rezoned to R-1, R-3 , R&D, andWJ-1 . )1 There has been no M-2 approved for any of this property (please see plat). - A few issues are still outstanding with the development. As can be seen from the plat, access is not being provided with this submittal. The developer has an agreement on the 0.26-acre tract along Graham in order to construct the north-south collector. The subdivision does not have access to Graham by way of the Victoria extension and is dependant on the Fry-Link, 1.29 acres, and Westfield Addition Phase 3 properties to get access.

Therefore, before any Final Plat is submitted, the access issue MUST be resolved. Access shall be from either Victoria or Graham. A~ces.~ ~h~~ugh Westfielg Eb.~:;e ~J~ not ad~g_~g!e. The City is requesting that the developer take water service from the Graham Road-Wellborn Road intersection. The new water line should be in the future TXDOT ROW along the back of the lots in Block 7. The City would like the developer to upsize this line from whatever is required for the project up to a 24" line. ~-?~ation=(-OP.+b.y_tbe..City.,js available to the \ Item No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 EDEL WEISS GARTENS, PHASE 1 Engineer's Estimate .

Please be aware that the City of College Station Drainage Policy and Design Standards requires a 25% reduction in flow area of all pipes 24" and less in the design of storm sewers. Technically, this calculates to a reduction in flow of more than 70% when the area (A) in Manning's equation is reduced. We allow the design engineer to use a 75% reduction in flow to simplify calculations. However, your design utilizes an 80% reduction in flow. Please explain your demand for this variance in writing for our consideration. 2. There are still storm sewer pipes in the system that exceed design standards either by excess flow or velocity. Please ensure compliance with City regulations unless you are requesting a variance in writing. It appears that flow information shown on the plans does not agree with the Drainage Report. Please show actual flows and velocities. 3. I have looked at the HGL sheets. These are a part of the Drainage Report. The Engineer of Record must stamp and sign each of these sheets for the record. For the record, please make any corrections you wish to these sheets before they are sealed and resubmitted. I will review the sheets and may ask you to show your calculations. 4. Please include energy dissipation structure or show velocity calculations on exit velocity for the RCP below Ardenne Court. 5. As requested in Staff Comments 1, please demonstrate in your report that the 8" sewer will serve all the properties shown in Edelweiss Gartens and all other down stream properties. This includes all of Westfield Phases 1, 2 and 3. Reviewed by: Spencer Thompson Date: August 21 , 2001 NOTE: Any changes made to the plans, that have not been requested by the City of College Station, must be explained in your next transmittal letter and "bubbled" on your plans. Any additional changes on these plans that have not been pointed out to the City, will constitute a completely new review. Staff Review Comments J:\PZTEXT\PZ05243.DOC Page 2 of 3 Edelweiss Gartens, Phase 1 Review Response The following is a response to the city review comment letter dated August 2, 2001 for the Edelweiss Gartens Phase 1 project. Planning: 1. Concerning the Plat, please change your boundary line (and acreage, ifneeded) to not include the proposed Victoria A venue. The plat has been updated to show this revision. Engineering: 1. Sheet 1: Please show 1.5" water line to lots 26 and 27 as 4" sewer lines. The plans have been updated to show this revision. 2. Sheet 3: Please show actual Q-10 and Q-100 for designed storm sewer. Please show calculated velocities for actual Q-10 and Q-100 flows at the designed slope, not theoretical slope. Use reduced areas where applicable for velocity calculations. Please plot HGL-10 and HGL-100 on profiles, as required. The storm drain must carry Q-10, while Q-100 must be maintained in the ROW. All jlowrates shown on the plans are calculated flows for each storm drain. The velocities shown on the plans are calculated JO-yr velocities based on design slopes. HGL-10 and HGL-JOO have been plotted on supplemental sheets. 3. Please include valve box detail showing 24-sq.in. by 4" concrete block at surface. The plans have been updated to show this revision. 4. It appears that several of the storm water lines exceed the flow allowed with the 25% reduction. Please check and verify. The calculated flow rates for all pipes less than 27" have been increased by a factor of 1.25, as shown on Exhibit C-3. This method eases the design of the spreadsheets found in the drainage report. Both methods of over-sizing the storm drains achieve the same result. Jn most cases, the size of the storm drain is increased by 3" in order to account for the additional flow or the reduction in cross sectional area. Differences can be found in the resultingfriction slopes, but they are small. 5. It appears the exit velocity of the RCP below Ardenne Court is very high. Please include energy dissipation in the outlet. The J 0-year storm velocity exiting the pipe is approximately 13. 87 fps. At the end of the concrete rip- rap pad the velocity is reduced to 4.45 fjJs. 6. Concerning the Drainage Report, the adjusted design flows should decrease with decreased cross- sectional area. Please show actual flows and allowed flows. Please show velocities based on actual installed slope and actual or allowed flows. Please see response for comment #4. Edelweiss Gartens Phase 1 Review Response Pagel 7. Concerning the Sewer Report, it is obvious from your report that an 8" line is sufficient for your anticipated service area. What is of concern, is whether the 8" line can efficiently serve as much of your subdivision as you want it to and Westfield Phases I, 2, and 3. The 12" line along the proposed East-West collector was designed to service this area. Please show calculations that demonstrate that the 8" can serve all you are intending it to. The computations for the offsite 8" sewer line include 135 lots in the Westfield Subdivision. This is shown on Exhibit F in the line segment between nodes L and M The calculations indicate the 8" line is of sufficient size to carry the peak flows from Edelweiss Gartens as well as those from the Westfield Subdivision. 8. Water Report is satisfactory. Please remember as you plan for future phases of this project, that the 24" water line along the proposed SH-40 ROW should be included in your design. It may be necessary to include easements for branches where applicable that were not shown on the preliminary plat. OP request should be based on the cost difference between the design shown in the water report and the design necessary for an efficient system utilizing the 24" water line. 9. Do you have the easements for street lighting as per McCord Engineering and Public Utilities?

Exmbi.IF OOH-teWcrREV.xls 9/1112002 Page l or 1 Spencer, I was finally able to reach Joel Mitchell regarding the computation of peak flows. Joel developed that spreadsheet several years ago when he worked here. The formula he used is taken from a book entitled "Design and Construction of Sanitary and Storm Sewers" published by American Society of Civil Engineers (1969). On Page 35 of that book is a graph developed from field data in Los Angeles that compares average flow rates and peak flow rates. Using that graph, Joel developed an empirical formula that describes the relationship which could be used in the spreadsheet. (I attached a file that has the formula on it because it involves log and exponential functions that I couldn't write using Outlook Express.) The graph shows that a peaking factor is not constant and it decreases as the average flowrate goes up. I will fax you a copy of it if you would like. Thanks. ***************************************** Kent Laza McClure Engineering, Inc. 1008 Woodcreek Drive, Suite 103 College Station, Texas 77845 (979) 693-3838 office (979) 693-2554 fax ***************************************** file://C:\Documents%20and%20Settings\sthompson\Local%20Settings\Temp\GW}00002.... 10/3/2002 Peaking Factor Formula for Sewer Lines from the ASCE Design Guidelines Peaking Factor= e-0.098563 In (Avg Flow + 0.96697) EXHIBIT E I Graham Rood _J l a· Sew.-Line []] FGN= 506' 8 8 6 6 f--r--+-+-+--+--+--+---l--l---l--i8 ( I I I I I j· 1------j 6 t---1 -....--~~~~g .O.D.~.U}J.~ 8 1271 8 (Optional)___, ~ 8 i ~ ~ 6 6 '' ,. 1 /"f" -, I \ . ~~o...a.-.....-----...\ I 29 I Bald Prairie Subdivision ' .
