• Phase II requirements • Purpose • Cost Share

• County share (80%)

Watershed Planning

• NPDES Requirements (Monitoring & Assessment)

• Stream Corridor Assessments (SCA) • Implementation Strategies

• Restoration Plans and TMDL’s

• Assessment of Controls (discharge characterization) • Chemical Monitoring • Biological Monitoring • Physical/geomorphic monitoring

• I.D.D.E. Sampling What are the objectives of the SCA?

• Provide list of observable environmental problems within a stream and along its corridors.

• Provide sufficient data for each problem to determine severity and correctability.

• Prioritize restoration efforts based on information collected for each impairment.

Potential Impairments Not Carroll County

Erosion Exposed Pipes and Pipe Outfalls

Channel Fish Blockages Alteration

Inadequate Unusual Buffer Conditions

Trash In-Stream Dumps Construction Prioritizing

Additional Information Collected:

• Adjacent Land Use

• Possible Cause

• Livestock Present

• Erosion Extent (length/Height)

• Type (Erosion attribute)

• Downcut, headcut, or widening

• Threat to infrastructure (Erosion) Impairment Ratings • Presence of Utilities (Buffer) 1) Severity: 1= Most Severe (wide reaching impact on aquatic life) • Location Plantable? 5= Least Severe (very little impact to stream corridor) • Blockage Type (Fish Barrier) 2) Correctability: 1= Minor (fixable with hand labor) • Type of Alteration 5= Major (require heavy equipment and significant funding • Location of Exposed Pipe 3) Accessibility 1= Easily accessible by car or on foot • Bottom of stream, streambank 5= Difficult to access by foot
