Project Overview The Indian Creek Watershed – a sub watershed to Plaster Creek – exhibits large flows into Indian Creek during storm events. This is due to the large urbanized drainage area. These large flows peak during storm events causing flooding of Indian Trails Golf Course. Additionally, these large flows cause erosion of the stream banks, which in turn moves sediment downstream altering the channel causing more flooding problems. The Plaster Creek Stewards aims to remove storm water runoff and pollutants from the greater Plaster Creek watershed through a variety of small projects, due to a lack of space in this fully developed watershed. This project acts as a small piece of the puzzle to solve the larger problem.

These rain gardens will help reduce peak flows and runoff. Additionally, Team 01 will design a plan for stream restoration on the north end of the stream.

Goal

Team 01 aims to reduce flooding atIndian Trails Golf Course by creating aseries of three rain gardens on thesite. These rain gardens will helpreduce peak flows and runoff.Additionally, Team 01 will design aplan for stream restoration on thenorth end of the stream. This streamrestoration will help to slow flows inthe stream and protect the streambanks against further erosion. Thegoal is to hold all runoff from the golfcourse for a 2-year 24-hour storm.

Design

Team 01 has designed three raingardens with the following sizes:• North: 7000 CF• Middle: 17000 CF• South: 4500 CFThese rain gardens are accompaniedby stream restoration which plans to:• Expand the channel• Implement a 2-stage Ditch• Stabilize the channel banksWith these implementations, the teamis able to meet the goal of maintainingall runoff from the golf course for a 2-year 24-hour storm event. Thesedesigns help reduce flood levels onsite by 2.16 inches for this event.
