The .rules which regulate the design, i nstallation and testing of domestic wastewater projects are found in 30 TAC, Chapter 317 , of the TNRCC's rules ~ ·t1t1t!rl ;--·~Destgn (;ri~r:la., f.or Sewerage Systems". All plans and specifications submitted for TNRCC appro.Ja l must comply with these rules. Beginning on September 1, 1994, severe budget reductions required the TNRCC to eliminate most reviews of domestic wastewater project plans and specifications . At most, only a cursory review of the proposed project was performed . A technical review to determine conform i ty with 30 TAC Chapter 317 has NOT been performed. The proposed project is approved with the following comments and conditions: 1 . An engineering report must be prepared and sealed by a Professional Engineer registered in the State of Texas. This engineering report must include all constants, graphs, equations, and calculations, which are needed to both justify the design and show full comppliance with Section 317.1 (c) of the TNRCC's rules requiring a final engineering report . Copies of this report s hall be made available to the TNRCC, upon request . 2. The final version of the project plans and specifications shall include any and all information necessary to show full compliance with the applicable requirements detailed in Chapter 317 of the TNRCC's rules . Copies of the final version of t he project plans and specificat i ons shall be made avialable to the TNRCC , upon request. P.O.

Any test results necessary to show compliance with the testing require - ments of Chapter 317 shall be made available to the TNRCC, upon request . 4. The TNRCC still maintains its review authority and may utilize this authority at any time in the future. If plans are to undergo review , TNRCC will notify you upon receipt of the project. Also, please be aware of Section 317.l(a)(2)(A) of the rules which states, "Approval given by the Convnission is not intended to relieve the sewerage system owner or the design engineer of any liabilities or responsibilities with respect to the design, construction, or operation of the project." 5. Within 60 days of the completion of construction, an appointed engineer must notify both the Permitting Section of the TNRCC's Watershed Management Division and the appropriate Region Office of the date of completion . The engineer must also provide written certification that all construction , materials and equipment, and test results were substantially i n accordance with the approved plans and specifications, the rules of the TNRCC and any change orders filed with the TNRCC. All notifications , cert i fications and change orders must include the signed and dated seal of a Professional Engineer registered in the State of Texas . 6 . All plans and specifications shall conform with any other waste discharge requirements and water quality standards established by the TNRCC, as the requirements pertain to a regulated discharge .

Street Construction Southern Plantation is a minor arterial, and as such is eligible for the participatipn in the additional 8 feet in width along the entire width constructed (from the existing paving to the western plat boundary). However the "offsite" portion of the street between the existing paving and the plat boundary is still the developer's responsibility. Because the alley is not indicated on the thoroughfare plan, no participation is provided by our ordinance. Draina2'.e Construction Other than qualifying bridges and culverts, no participation is provided by the City for drainage facilities. Sewer Construction The ordinance does not provide for participation in lines of this size, nor would the City participate in offsitejmprovements required for service. Water Construction The Ordinance provides for participation for the additional sizing of the 12 inch line, along the entire length of Southern Plantation, both on and off site. However the City will not pick up the entire cost of the off site portion. The Oversize Participation provisions are intended to allow the City to increase the capacity of various infrastructure facilities to meet the projected demands in ·the area, beyond the actual projects being constructed. Those facilities required by a project, such as access and utility service, are always the responsibility of the developers to the level needed for their projects . Home of Texas A&M University ---~-· --·-·----~---------------------' By our calculations, these factors will significantly reduce the participation recommended to Counc il (tentatively scheduled for January 12th), therefore we suggest that the participation request be revised to reflect these changes . With regard to the improvement plans , all of the onsite improvements are ready for approval. However we have not seen any plans or revised drainage calculations addressing the changes proposed to the existing basin . Because these modifications are a recommended condition of plat approval, we will need to review these additions and approve them concurrently with the 'onsite' improvement plans . Should you have any questions or concerns, please call .

Because this is a replat of a previously platted and partially constructed area, the report evaluates the proposed improvements, as well as, the existing infrastructure outfalling into the detention pond located on Lot 40, Block 10 of SHENANDOAH Subdivision. PRIMARY DRAINAGE BASIN DESCR.IPI'ION: The proposed site is bounded on the southwest by the College Station City Limits and on the northeast by SHENANDOAH, PHASE ONE Subdivision, the adjacent land to the north, west and south is undeveloped. The site is situated approximately along a ridge line between two un-named tributaries of Spring Creek with an estimated 80% of the planned development draining eastward into the existing portion of SHENANDOAH Subdivision. Some of the stormwater enters the existing storm drain system at the intersection of Decatur Drive and southern Plantation Drive. Since these inlets are undersized, the remaining flow continues eastward along Southern Plantation drive to the low point inlets east of the Hunter Creek Drive intersection. The remaining 20% of the planned development sheet- flows in a southwesterly direction toward an un-named tributary of Spring Creek. The tract is relatively clear with 2% maximum slopes. Some grading has been completed on the site at the time of development of SHENANDOAH, PHASE ONE Subdivision and the construction of the storm drain system in 1983. Offsite storm water flows across the site from an approximately 1. 9 acre drainage area within the undeveloped tract to the north. A previous drainage study for the site may have been submitted with the development of the SHENANDOAH, PHASE ONE Subdivision in 1983, but no such report can be found by the City of College Station Engineering Staff. GENERAL CONCEPI': The stormwater drainage patterns are shown on the Drainage Area Map, Exhibits "A(Pre)" & "A{Post)". The site will be graded such that all the flows from this subdivision will be captured in storm drain inlets and conveyed to the detention pond in the existing cast-in-place concrete outfall line. The detention pond was built with the intent of providing detention for the area. Evidence of this fact can be seen by reviewing the original SHENANDOAH, PHASE ONE construction plans. 2 SPECIFIC DETAILS: In order to demonstrate the function of the existing pond, we developed a model of the system using the Rational Method and Triangular Hydrograph per the City of College Station Drainage Policy and Design Standards (DPDS). The watershed contributing to the function of the detention pond was modeled to determine the effectiveness of the detention. The model utilized the 5, 10, 25, 50, and 100-year storms per the DPDS at two ( 2) minute time intervals (NMIN). The model was designed for the spreadsheet software "Microsoft Excell". The "Stage -Stor~ge Curve" and the "Stage -Discharge Curve" (See Exhibits "C" and "D") for the storage routings are determined from on-the-ground survey data of the existing pond and the Grading Plan of the proposed pond. To simulate the amount of flow which bypasses the pond, the inlets in Area 2 are assumed to convey all the flow, and inlets on-grade at the intersection of Decatur Drive and Southern Plantation Drive, and are assigned a capacity of one cfs per linear foot. The flows from Area 1 are assumed to drain to their natural outfall point for existing conditions, and assumed to be intercepted to the limit of the pipe capacity in the proposed condition. In this manor, flows in excess of the inlet capacity may be allowed to bypass the storage routing of the pond. The flows, except a portion from Area 1, are rejoined after the storage routing and the total peak flows are compared to determine the effectiveness of the system. (The Q~ and Q100 storm events will exceed the capacity of the storm drain system and will "spill-over" 3 in a southwesterly direction consistent with the existing conditions per Exhibits "A(Pre)" & "A(Post"). Exhibit "A(Post)" is a Drainage Area Map outlining the proposed drainage areas and associated inlets. Exhibit "B" is the results of the model routings. They are in order (5, 10, 25, 50, and 100-year storms). A summary of the total peak flows for the study point immediately downstream of the existing detention pond are shown in the Table on Exhibit "A(Post)". The peak flows are less than the existing flows in all cases. Exhibit "C" is the "Stage -Storage Curve" for the pond. Exhibit "D" is the "Stage -Discharge Curve" for the pond outlet, an 18" pipe with a standard concrete headwall. Inlet and pipe sizes are calculated using the Rational formula and the guidelines provided in the DPDS (n = .014). All structures are designed for the 10-year storm and calculations are shown in Exhibit "F". The existing pipes adjacent to the site are adequate to convey storms larger than the 10-year flows in pressure flow. Additionally, easements and the street rights-of-way are designed to carry flows in excess of the pipe capacity. CONCLUSION: The drainage plan outlined above will satisfy the requirements of the City of College Station Storm Water Management Plan. The existing pipes adjacent to the site are adequate to convey this development's flows into the detention pond. The proposed 4 stormwater detention modifications will successfully control the peak discharge until the downstream conditions can accommodate the flows. 5 SHENANDOAH PHASE ONE RESUB.DIVJSJON OF LOT 25, BLOCK 14 City of COLLEGE STATION BRAZOS COUNTY, TEXAS DRAINAGE STUDY REVISED .DECEMBER, 1994 ~ f If/~ f~frftJ v~' /1 1YJ7 1"1/ PREPARED BY.· .McCLURE ENGINEER/NC, INC 1722 BROAD.MOOR, SUITE 210 BRYA~ TEXAS 77802 5 YEAR EXISTING HYDRCGRAPH DETENTION POND STORAGE ROUTING AREA 1 AREA 2 AREA 3 AREA 4 TO POND COLlOOl POND COLUlll FLOW In+In+ 1 2Stdt 2Sldt Qn+l TOTAL STREIT Qux • 15.75 18.49 55.66 19.33 5.88 I 1 • EL!V.
