Watershed Statistics Total Watershed Acreage = 2240 (3.5 sq miles) Total Impervious Acreage = 739 (33%) Total Miles of Streams ~ 10 miles
What is the big picture problem? Long Creek and its tributaries do not meet state water quality standards
What is the big picture problem?
Urbanization is Hard on Streams • Vegetation along the stream is removed
Urbanization is Hard on Streams • Vegetation along the stream is removed • Impervious surfaces heat and speed water to the stream
Urbanization is Hard on Streams • Vegetation along the stream is removed • Impervious surfaces heat and speed water to the stream • Streams channelize, floodplains fill
Urbanization is Hard on Streams • Vegetation along the stream is removed • Impervious surfaces heat and speed water to the stream • Streams channelize, floodplains fill • Increased pollutant load
Long Creek is Impaired • Stream flow has been altered

Nutrients Blanchette Brook North Branch Main Stem South Branch
PAHs (Polycyclic Aromatic Hydrocarbons) • Detected several PAH chemicals commonly associated with coal tar sealants for the third consecutive year

Monitoring Summary The data collected to date suggest the following: – Temperature and dissolved oxygen are issues in the upper portion of the watershed. – Chloride is an issue in the south and north branches. – Metals and nutrients are issues throughout the watershed. – Water quantity is a known issue throughout the watershed and is being analyzed further.
Monitoring Summary Preliminary data suggest the following: – Improvements in dissolved oxygen in Blanchette Brook and the North Branch – Increased chloride concentrations in the upper and lower main stem
What issues are we addressing? • Implement non-structural measures – Chlorides, Metals, Nutrients • Treat 150 impervious acres – Volume of water (stream flow), metals, nutrients, dissolved oxygen, temperature • Implement 10 stream habitat mitigation sites – Dissolved oxygen, temperature, in-stream habitat, fish passage
Goal: Meet Water Quality Standards by 2020 • Implement non-structural measures – Vacuum sweeping, catch basin cleaning – Operation & Maintenance Plans – Targeted education – Land use planning & standards promoting low impact development • Treat 150 impervious acres – 44.69 acres treated (30%) • Implement 10 stream habitat mitigation sites – 2 completed (20%)

Non-structural – Catch Basin Cleaning
Non-structural – Site/BMP Inspections • Inspections were focused on properties where improvements were needed.
Non-structural measures – Winter Maintenance • Chloride management is a regional problem and should have a regional solution. • LCWMD requested that the Maine DEP explore: – the development of state- wide salt application BMPs

Landowner Obligations • Pay Assessments on time – Budget for next fiscal year mailed Feb 1 – Next year’s assessments mailed April 1 – Fiscal Year - July 1 – June 30 – Invoicing biannually - January & July • Provide easements for BMPs in Plan
Landowner Obligations – talk to us! Tell us when you have plans to … • Construct new impervious • Redevelop • Sell your property • Resurface pavement • Change contractors for winter maintenance or landscaping Credit: Bill Watterson
Landowner Obligations • Implement Operation & Maintenance Plans – Maintenance of conservation practices (if you installed it, you maintain it) – Winter maintenance – Landscaping – Vacuum sweeping – Catch basin cleaning – Inspection of BMPs
Areas for Exploration – Coal Tar Sealants • Coal tar-based sealcoat produces 30 times more PAH s than no sealcoat. • PAHs may harm fish and, under some conditions, pose a risk of cancer to humans.
What’s Next? Hydrological study • Applied mapping • Comprehensive watershed • analysis to develop recommendation for future work
Landowner Participation 3.15% - Individual Permit 3.15 % - Pending 93.7 % - General Permit 127 designated parcels
