In that discussion, Steve indicated that per the ordinance, land dedication for this property would be less than one acre, therefore, this property would be required to pay a fee in lieu of the land dedication. This fee equates to 71 units times $457 /unit, for a total parkland dedication fee of $32,447. In a meeting with the Development Services staff on Monday, December 17, the Homeowners Association Covenants and Restrictions were discussed and requested with the final plat submittal. We realize that these covenants and restrictions need to be reviewed in light of the PDD -H zoning and the final plat, however they were not available for this submittal.

File Todd Sullivan From: Kris Lehde To: Ric Ploeger; Steve Beachy Date: 1/9/02 2:10PM Subject: Board Meeting of 1/8/02 The following is a run -down from last night's board meeting: Cutis, Item #6 will pertain to your area. 1. The Board was in consensus of having the Master Plan Subcommittee meet and bring their recommendations back to the Board for approval. A Master Plan Subcommittee needs to be set up (John N., Glen D., and Don Allison). 2. A focus group meeting with Board members Don A. and Bill D. needs to be set up with the local development community (I have the names, addresses, and a -mails of who attended the last focus group meeting) to discuss possible developer incentives. 3. Agendas will need to be posted for the following: - Feb. 5th Special Meeting to discuss Future CIP Projects. The meeting will start at 6:00 p.m. with dinner. - Feb. 12th Regular Meeting. The meeting will start at 6:00 p.m. with dinner. - Feb. 19th Joint Meeting with Bryan PARD to discuss the Madeley Park Project. The meeting will start at 7:30 p.m. (location to be announced - probably Bryan Municipal Building). Pam is checking to see if the Bryan PARD Secretary will be taking those minutes. 4. Ric, the Board had several recommendations for the future CIP list. I will have to type up the minutes to get you all of the details. Although, some include playground covers, joint projects with the new high school (i.e. tennis courts with lighting and shade covers), and moving the Luther Jones project under Community Facilities. Also, the Board would like the future CIP project list with prices and the individual CIP request forms with descriptions sent to them by snail mail in advance of the Special Meeting on Feb. 5th. We'll need to get this out soon. 5. The Board would like a status sent to them concerning the progress of the Interlocal Agreement that was sent to Legal for the Jack and Dorothy Miller Jogging Tract. If we can't get a response to the Board before the Feb. 12th Regular meeting, they would like for this to be an agenda item for that meeting. 6. Parks Maintenance Standards. The Board agreed that they looked good, but to help with the consistency of the evaluation process of the Parks, it was suggested that the Parks Operations Supervisors train how to grade or grade in a group (Paul, Gary, Scott). 7. The Board would like a section added to the Park Land Dedication Checklist called "Project Location" that will give the Board an idea of where the dedication is located. Including a map of the dedication may also be helpful. 8. The Skate Park subject is a dead issue. The following motions were made: 1. Senior Facility Report was approved unanimously. 2.

Box 9960 College Station, TX 77840 RE. Sanitary Sewer Oversize Participation Study for the TCC Subdivision Dear Spencer, The following is a Sanitary Sewer Oversize Participation Study for the TCC Subdivision. The subdivision is located on the east side of Harvey Mitchell Parkway (FM 2818) and approximately 1600 linear feet south of the Luther Street & FM2818 intersection. The total acreage of the area being considered for development is approximately 5.953 acres. The TCC Subdivision is bordered on the north by Lot IA and Lot 2A, Block 1 of the Melrose Subdivision as well as the Fairfield Residential development, on the south by an undeveloped tract and on the east by the Walden Pond development. As part of the development of this tract, the Development Services Department requested an increase in diameter and depth of the sanitary sewer system through the TCC Subdivision to allow for the development of Lots lA and 2A, Block 1 of the Melrose Subdivision by gravity sewer. Currently Lot 2A does not have access to any form of sanitary sewer service. Lot IA, developed as the SAE Fraternity House is served by an injector system, which lifts the effluent to a manhole on the Melrose Apartment site. If the TCC Subdivision provides this gravity sewer line to Lots IA and 2A, the additional size and depth, according to the City of College Station Subdivision Regulations, would be a candidate for sanitary sewer oversize participation by the City. TCC Subdivision Design Mitchell & Morgan, LLP completed a preliminary sanitary sewer analysis for the TCC Subdivision. We first analyzed the use of a six (6) inch sanitary sewer line connecting to the existing sanitary sewer manhole on the Walden Pond Property at a 0.6% slope and a six (6) inch line running northeast at 0.6% slope within the drive aisle of the TCC Subdivision to the property line between the TCC Subdivision and Lot IA of the Melrose Subdivision. As seen on the attached spreadsheet, this line size and slope has enough capacity for the effluent from the TCC Subdivision. TCC Subdivision Design w /Lot IA & 2A, Block 1 of Melrose Subdivision Mitchell & Morgan, LLP then analyzed this same six (6) inch diameter pipe with the flows from the TCC Subdivision and Lots IA & 2A, Block 1 of the Melrose Subdivision. As seen on the spreadsheet, this size and slope was not sufficient to serve these additional lots. With the slope of 0.6 %, the pipe very quickly lost sufficient cover as it entered Lots IA & 2A, Block 1. Therefore, Mitchell & Morgan, LLP increased the pipe diameter to an eight (8) inch with a minimum slope of 0.4% for a portion of the line length with the remainder constructed as six (6) inch line @ 0.6 %. With the increase in pipe diameter and the decrease in required slope, it appears that adequate cover will be provided to allow for the development of Lots IA & 2A, Block 1 of the Melrose Subdivision and the TCC Subdivision. However, the ground elevations for Lots I and 2A, Block 1 are unknown and are estimated from aerial topography. Their accuracy is significant when deciding if there is adequate depth for the sanitary sewer line, therefore, for Lots 1 A and 2A adequate cover should be on the order of 5 feet because of the estimated topography. Mitchell & Morgan, LLP finally analyzed the system by replacing the entire six (6) inch diameter pipe to an eight (8) inch diameter pipe at 0.4 %. As seen on the spreadsheet, this size and slope was sufficient to serve these additional lots. With the increase in pipe diameter and the decrease in required slope, it appears that adequate cover will be provided to allow for the development of Lots IA & 2A, Block 1 of the Melrose Subdivision and the TCC Subdivision. As shown on the attached drawing, we have illustrated the sanitary sewer lines that would be eligible for oversize participation. Attached is an itemized cost difference between the line size and depth required for our development and that required for adding Lots 1 A & 2A, Block 1 of the Melrose Subdivision. We have estimated our oversize request at $7,950.00. We would appreciate your placing this request at the next available council meeting agenda for consideration. As always, we welcome any comments or questions. n i SinicOely, � Veronica J.B. Mqr n, P EI Managing Par Cc: file Todd Sullivan December 5, 2001 '' rn R Quo c C - - 0 U c CM 025 4 rn i. Cd = c .

At the present time, the FIRM does not provide a detailed study of this portion of the watershed. This analysis more accurately establishes the 100 -year base flood elevation for Whites Creek, upstream of the culvert at Harvey Mitchell Parkway (FM 2818). The runoff calculations were performed using the Rational Method, which can be seen in Exhibit B. For this calculation, a Time of Concentration (T of 20 minutes was used. This was found by using the SCS TR- 55 method, which yielded 30 minutes. Due to uncertainty with respect to land cover in the drainage basin, this value was reduced to 20 minutes. HEC -RAS 3.0 was used to calculate the water surface profile for the channel. The HEC -RAS output can be seen in Exhibits C -1 to C -3. Several assumptions were made for this analysis. The first of these is that the pre - development and post - development peak flows for the Canyon Creek Townhomes site will remain the same in accordance with the College Station DPDS zero runoff increase policy. In addition, as a result of having insufficient information for the surrounding tracts, the runoff from these developed areas was assumed to be undetained. A runoff coefficient of 0.4 was assumed for currently undeveloped areas of the drainage basin and a value of 0.9 was used for the developed area. The drainage area map can be viewed in the attached Exhibit A. Finally, for the hydraulic analysis, the normal depth of the channel downstream of the culvert was used as the downstream boundary condition. The additional runoff downstream of the culvert was accounted for in the HEC -RAS analysis and amounts to less than 6 cfs. Q o A C o °' °' V =� as rn L r = �o C ca- Mc ...
