Watershed Specific Recommendations

William Lehr Ditch - Stony Creek Watershed

	The following discussion is based on drainage problems or complaints that were identified in the William Lehr Ditch - Stony Creek Watershed for existing and future concerns noted in Chapter 2 and Chapter 3 of this Master Plan. Each issue, concern, or opportunity is restated in simple terms, and then followed by an evaluation of the promising alternative solutions (if applicable), a discussion of the recommended improvements, and an estimate of the associated costs. The cost estimates are provided for budgeting purposes only. A copy of these cost calculations is included in Appendix 4. They are based on field observations and limited data. Actual cost of construction and design may be more or less depending on additional information that would be gathered during the design phase. For the issues that had several promising solutions, CBBEL explored the solutions and narrowed them down to the best solution with input from the Town of Fishers staff. Table 5-2 at the end of this Chapter provides a summary of the recommended improvements. Chapter 6 of this Master Plan will focus on implementation of the recommendations identified.

Other Issues (1)

	WL1 Issue Based on the Stony Creek Watershed Plan, existing condition flow rates in the watershed are lower than the default Town or County release rates for new development. In the Stony Creek Watershed Plan, the post development 11-100 year peak flow discharge was recommended to be limited to 0.04 cfs per acre. The 0-10 year post development release rate was recommended to be limited to 0.01 cfs per acre. It appears that these restrictive release rates have not been made a part of the County ordinance. Recommended Improvement Based on the goals and performance criteria established for this Master Plan (Chapter 4), it is recommended that the Town coordinate with the Hamilton County Surveyor’s Office to add the Stony Creek Master Plan’s calculated existing condition flow rates to the County Surveyor’s list of restrictive release rate watersheds. The estimated cost of staff time to coordinate these efforts with the County is $1,000. Back to Watershed List
