The purpose of this study is to assess significant stream corridors, the storm sewer network and stormwater management approaches within the City of Johnston and its potential growth boundaries. The study will evaluate current watershed properties and analyze how these are expected to change, based on land use changes projected in the City's comprehensive plan.

Outcomes of this process will be:

• Descriptions and maps of the existing physical environment within the study area
• Information about the local hydrologic system and its components including drainage systems previously constructed and existing and potential problems related to them
• Complete assessment of the Little Beaver Creek and Beaver Creek corridors as they currently exist in Johnston (adjacent land use, bank stability, canopy, riparian zone cover and point source locations)
• Recommended management plan and opportunities for improvement
• The effect to the plan on the drainage system
• Identification of high priority areas for preservation, enhancement, restoration and any conflicts with wetlands and land use
• Objectives and policies, including management principles, alternatives and modifications, water quality improvement and protection of natural characteristics
• Potential conflicts between the watershed plan and existing plans of local government units
• Proposed implementation program
• Timeline and procedures for amending the plan
• Public participation
