This drainage letter and the supporting design methods were performed in accordance with the City of College Station's Drainage Design Policies and Standards. Information used for the design, and the resulting calculations, of these drainage improvements are as follows: •!• A-1: Lick Creek Watershed Map; ·:· A -2: FEMA Map Panel; ·:· A -3: Existing Drainage Area Map; •!• A -4: Proposed Drainage Area Map; ·:· A-5: Paving & Grading Plan •!• B-1 : Pre-Development Hydrology; ·:· B-2: Post-Development Hydrology; ·:· B-3 thru 8 : Runoff Hydro graphs; ·:· B-9 : Routing Calculations General The project site is a 25.44 acre lot (Belmont Place, Section Two -Tract One & Two , Block Three) and is located within two watersheds, Lick Creek and Bee Creek. Development improvements for this project will be contained solely in the Lick Creek watershed (see Exhibit A-1). Additionally, this project site it is not located or adjacent to any FEMA mapped floodplain (see Exhibit A-2). In general , undeveloped areas on this property are vacant, covered by native weeds and grasses, and have no tree coverage. Developed areas consist of the current hospital CDl-149-0 180 -L04 Page - 1 '. .. '• College Station Medical Center Bed Tower Expansion Drainage Letter -Revisions #I December 12 , 2003 facilities and associated parking areas. The existing and proposed drainage basins that contain the proposed improvements are attached (see Exhibits A-3 & A-4). Calculations performed from data obtained by an on-the-ground survey illustrate that this existing detention pond has an existing storage volume of approximately 62 , 176 ft3. Its maximum pond depth, for the 100-year rainfall event is 2.61 feet occurring at an elevation of 303.00. This provides for a 0.50 foot freeboard of storage since the top of berm is at an elevation of 303.50. Three (3) cross-timber structures exist that provide for overflow weirs when ponding occurs above elevation 303.00 Runoff is metered through four (4) 10" PVC drain pipes that discharge flow to the south. Metered runoff quickly spreads to sheet flow conditions, but within a short distance reaches the curb and gutter of Birmingham Drive. Thence, runoff is carried in the street's gutter to the west and into a storm sewer culvert. At this point, runoff is conveyed south by means of an improved channel parallel to Coastal Drive which reaches the confluences of the North Fork of Lick Creek. Hydrology Using the Rational Method for hydrology modeling, runoff values were determined for each drainage basin (existing & proposed). Results from the 2, 5, 10, 25, 50 & 100-year rainfall events for these drainage basins are summarized below in Table# 1 (see Exhibits B-1 & 2).

By graphical comparison of these hydrographs, the expected increased detention storage volume was calculated to be approximately 22,500 ft3 for the 100-year rainfall event. Each studied rainfall frequency is summarized below in Table #2.

This drain will be replaced by a pipe of identical size and at a matching grade of 1.07%. Also , an additional overflow weir will be placed in the new detention pond berm for flows above the 100-year rainfall event. Using the runoff hydrographs for both existing and proposed conditions, flows were routed through the existing and proposed detention facility to determine expected runoff rates (see Exhibit B-9). These stage-storage relationships , for both existing and proposed conditions are summarized below in Table #3.

The pond parameters for proposed conditions change to a maximum pond volume of 66 , 116 ft:3 at a depth of 2 .36 feet with an increased outflow rate to 35 .60 cfs. A proposed modified pond with a pond CDJ-149-0180-L04 Page -3 .. College Station Medical Center Bed Tower Expansion Drainage Letter -Revisions #1 December 12 , 2 003 storage volume of 79,298 ft3 at a maximum depth of 2.61 feet is designed for this project and therefore exceeds the expected storage requirements. Ultimately, the total change in runoff rates discharging off the property can be compared by review of the sums of DA Xl and X2 to DA Pl and P2. This comparison is made below in Table #4 for the 100-year rainfall event. A negligible increase of 1.38 cfs is expected during this worst-case flooding event. TABLE#4 I OU-Year D .A.

Page 1 I November 10 , 2003 Mr. Tom Jackson, CEO College Station Medical Center PO Box 10000 College Station, TX 77842-3500 RE : College Station Medical Center Development Plans Dear Tom: I believe we have good news, and let me advise you there has been a change in the City's approach to your development plans since we met last Wednesday. Upon further review of our subdivision regulations , staff has determined that you will be able to resolve the Normand Drive roadway issue without a development agreement. lbis should allow your project to move forward even faster than we discussed last week. After College Station Medical Center submits a development plat with the dedication of the Normand Drive ROW and related utility easements, the City will be able to accept payment for the hospital's portion of Normand Drive that can be escrowed. This is contingent upon receipt of your engineer's estimate for the cost of your portion of the street, and acceptance of the estimate by the City's Engineer. It is City staff's understanding that you should be able to submit the development plat within the next few days. Please let me know if what has been outlined above is acceptable to the College Station Medical Center staff and consultants . If you should have any questions, please do not hesitate to contact me .
