4. STORM WATER MANAGEMENT

Adopt storm water management and erosion control regulations for design and construction



Storm Water Management and Erosion/Sediment Control

• Storm water management reduces quantity, and improves quality, of runoff in the watershed

• Site based approach reduces long term costs to community


5. STREAM AND WETLAND SETBACKS

• Adopt stream and wetland setback zoning regulations

Case Study Project

Developed by CDM, Inc.

Under the Direction of Ohio Lake Erie Commission and Cleveland State University

http://lakeerie.ohio.gov/

Project Description

Develop case studies that illustrate and increase understanding of the land development implications of implementing OLEC Best Local Land Use Practices

Engage stakeholders in land development in identifying key opportunities and barriers to use of best practices

Use case studies in training workshops


Project Objectives

Resolve real and perceived barriers to acceptance of best practices by: Developers Local Governments Buyers / tenants

Illustrate how properly-applied best practices can reduce costs and enhance property values

Provide adequate detail to support cost-effective implementation

Be repeatable for on-going education


Managing Storm Water Quantity

Impervious Surface: surface with minimal infiltration

Impervious surface model: 5 to 8 % change triggers degradation of watercourses


This report calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.
