summary of the activities the jurisdiction(s) will undertake during the reporting cycle and any changes to BMPs or measurable goals and all relevant data (monitoring) obtained during the reporting period. The Lucas County Stormwater Management Plan and the Stormwater Management Standards Manual recommends three model documents for the improvement of water quality for adoption by local communities: 1. Erosion and Sediment Control Rules 2. Riparian Setbacks 3. Conservation Development These documents are related to zoning issues within village, city communities and townships, not the county. Therefore, townships would adopt these documents as resolutions and the villages and cities adopt the documents as ordinances. The three documents provided are models for local agencies to refine to their community ideals for the protection of water quality. Sediment and soil erosion contribute to degraded water quality, while the protection of the riparian vegetation along the waterways works to protect and buffer those streams from erosion. Protecting a riparian setback along a waterway also provides habitat and corridors for wildlife protection. The document on Conservation Development offers an option for communities to proceed with development, yet work to protect open areas for green space and recreation. We ask for your participation to protect and enhance water quality with responsible management of stormwater. We all depend on clean water for our drinking water source, recreation, and industrial use. Every drop counts. Model Language Documents In following with the guidance of the regional stormwater management plans and the Ohio Environmental Protection Agency (EPA) under the guidance of the Clean Water Act, for water quality management, model documents are provided for area communities. Many communities in Northwest Ohio are affected by the U.S. Environmental Protection Agency (USEPA) Phase II Stormwater Regulations. The area jurisdictions have responded by submitting stormwater management plans to Ohio EPA based on regional model documents provided for that specific reason. There are also communities and jurisdictions guided by the act of responsibility for water quality that choose to adopt local ordinances for water quality protection. Jurisdictions have reported in stormwater management plans the intent to adopt local ordinance language for the protection and responsible management of local land use and water resource Third Edition Stormwater Standards Manual September 2008 Page 180
protection. Water quality management under the Clean Water Act contains legal planning for local community waterways and the waterways of our nation. Many communities across Ohio have adopted ordinances to manage stormwater by controlling erosion and sediment pollution (non-point source) as well as protecting waterways by adopting Riparian ordinances for vegetative protection and wildlife habitat along local waterways. Responsible local action may be accomplished by adopting ordinances to meet water quality measures recommended by the stormwater management plans. The Conservation Development document in Appendix C is provided to jurisdictions to allow the flexibility of choice in water quality management. Jurisdictions may choose between adopting the Riparian model or the Conservation Development model as the responsible selection for that jurisdiction. Model Language Documents are provided in Appendix C to assist area communities in northwest Ohio to define and adopt water management ordinances. Model language is provided as a guideline resource for communities. The model documents are intended for review and revision by legal authorities of the jurisdiction.
