1. Campus Storm Water Proposal A Storm Water Solutions Project

2. Analysis of Storm Water Runoff on the Texas State University Campus and Proposed Locations for Storm Water Detention Ponds

3. Summary Campus Proximity to the San Marcos River Environmental Stewardship Campus Master Plan

4. Purpose Out Of Date Storm Water Management The Problem of Pollutants and Sediments In Our River Impervious Surfaces Best Management Practices (BMPs)

5. Scope The area covered for this analysis is the physical property owned by Texas State University, including all buildings, parking areas and sidewalks, as well as all the green spaces.

6. Data Shapefiles From Mr. Bob Stafford – 1 Foot Contour Lines – 60 inch drain – Existing Storm Drains – Green Space – Impervious cover – Campus Master Plan Primary Data – GPS Points – Pictures

7. Methodology The analysis of our data will include the following procedures: 1.Formulate a watershed analysis model based on the ArcHydro extension in ArcMap. 2.Detailed slope analysis will be accomplished by utilizing the Texas State DEM model. This model will enable our team to best formulate slope calculations along with runoff frequency and speed in our predetermined runoff zones. 3.Create a model of water flow for 2 inches of precipitation. 4.Determine the size of all impervious surfaces located in each runoff zone.

8. Methodology Continued 5.Determine the deposit of sedimentation from green zones and proposed construction sites into storm water network. 6.Determine the adequate detention pond size for each runoff zone. Topographic map analysis along with spatial analysis of available land will be done to ensure correct placement of each proposed storm water detention pond. 7.Analysis of the Texas State University underground storm drain network. This will determine the desired location of each storm detention pond in correspondence to the total water flow from the associated pipe network.

9. Implications Expanding Campus – Construction – Sediment Runoff Outdated Water Runoff Management System Need for Storm Water Detention Ponds
