1 Save The Bay STORMWATER FINANCING THE REGULATIONS ROBERT BRUTUS CANTOREGGI TOWN OF FRANKLIN DPW DIRECTOR NOVEMBER 17, 2011

2 Franklin, At a Glance Suburban, Bedroom Community Population: 32, 800+ Density: 1,231 per Square Mile Total Land: 27 Square Miles 4 Square Miles of Impervious 115+ Miles of Drain Pipe Catch Basins 500+ Outfalls 200+ Treatment Basins Sediment Forebays Stormceptors Detention / Retention Basins

3 Triadic Approach STORMWATER WASTEWATER DRINKING WATER

4 Integrating Structural BMPs LID Integration for both new construction and redevelopment 319 Grants (NO LONGER AVAILABLE!!!) Reductions in impervious surface where available Opportunities for testing and experimentation CZM Grant for Stormwater Feasibility Study

5 Redevelopment Case Example Bright Hill Estates Developed in early 1980s 32 Foot Wide Road - 26 Feet is new Standard Sidewalks on Both Sides After Reconstruction Reduced Road Width to 28 Feet Eliminated One Sidewalk Reduced Materials = Increased Savings

6 The Result 70,000 square foot reduction in impervious surface Dunkin Donuts 15,533 Sq Ft Burger King 30,307 Sq Ft Total 59,756 Sq Ft Gas Station 13,956 Sq Ft

7 Emergency Culvert Reconstruction Before Erosion resulted in structural failure at downstream culvert headwall

8 Emergency Culvert Restoration After Reconstructed culvert headwall and included the installation of a sediment forebay and deep sump catch basins

9 Anchorage Road Reconstruction Removal of 1 Sidewalk 30 foot roadway reduced to 28 feet Cul-de-sac to be removed and replaced with rain garden Public education sessions were held to educate and increase resident support

10 319 Grants Clean Water Act Section 319 addressed the need for federal and state agencies to assist local agencies in nonpoint source efforts.

11 Panther Way 319 Grants Construction of an off-line infiltration basin to treat first flush from 137 unit condominium complex Complex previously had no structural BMPs Provided a case example BMP in a high traffic location (High School, Middle School, Police Station, Skating Rink, Playing Fields, etc.) Recharged Approximately 22,000 cubic feet of runoff. Estimated 80% TSS Removal Estimated 60%-70% Phosphorus Removal

12 Lockewood Drive 319 Grant

13 CRWA Building Blue Project Focused on the Spruce Pond Sub-watershed Took a concentrated look at roughly 1 square mile area to determine site specific BMPs for the area that would provide the greatest bang for the buck

14 Estimated Phosphorus Load by Drainage Area Phosphorus Loads were developed from land use classifications and the percentage of impervious surface within that specific land use area.

15 Washusett Street Reconstruction Installation of 5 Rain Gardens $80,000! Municipal property available Roadway under reconstruction Financed through water line replacement

16 Lessons Learned Treat the first flush Infiltration is the most cost effective strategy for pollutant removal Detailed stormwater mapping and plan information is very important Low cost solutions still provide benefit

17 Draft MA North Coastal Watershed Significant Additions to the current 6 Minimum Control Measures More Focus on Public Outreach and Education for Targeted Groups (residents, businesses, developers, industrial facilities) Drastically More Intense Illicit Discharge Investigations Wet & Dry Weather Stormwater Outfall Sampling Update Regulations to Incorporate MA Stormwater Management Standards (projects >1 acre regardless of Wetlands Protection Act jurisdiction) Evaluate Feasibility of Green Infrastructure (rain gardens, green roofs, etc.) Evaluate Methods for Reducing Impervious Area Program Must Address Impaired Water Bodies & TMDLs

18 TMDL Phosphorous Requirements Phosphorous Control Plan (PCP) where such TMDLs are completed Development & Implement Within 4 Years Complete PCP within 10 Years Estimate Annual Phosphorous Load Reductions TMDL Total Mass Daily Load Establishes the amount of a pollutant that a water body can assimilate without exceeding its water quality standard for that pollutant. TMDL addresses the problem of cultural eutrophication which has resulted in the production of excessive plant life because of disproportionate levels of pollutants from human activities.

19 EPA Residual Designation Authority (RDA) Permit Franklin, Bellingham & Milford, MA (Charles River Watershed) Private sites with >2 acres of impervious surface are required to obtain a permit Timeline Draft EPA Permit Issued on November 12, 2008 Amended Permit Issued on April 20, 2010 Public Comment Period Closed on September 30, 2010

20 EPA Residual Designation Authority (RDA) Permit Creation of a Stormwater Management Plan Development of SOPs for Pollution Prevention, O & M, Employee Training Phosphorous Reduction Plan or The Ability to Capture 1 of Stormwater On-site Does NOT Apply to: Government Property Sporting & Recreational Camps RV Parks & Campsites Mobile Housing Communities Standard Single Unit Residential Homes Multi-Family Units with 4 or Fewer Units

21 Problems When does the new permit become finalized? Phase II permit expired over 3 years ago (May 1, 2008) Moving Target Difficult to gain financial support for a permit that does not yet exist Teacher, Police Officer, Firefighter or Rain Garden? Lack of Public Support no noticeable impairment Lack of crediting for previously completed work No support for Watershed Wide Initiatives Shared Services, Combined Resources, Group Buy-In, Etc.

22 and more Problems Difficult to Comply with Existing Regulations Directly Negates Economic Development Initiatives Cost Estimates for Implementation Town: $65 Million Private Entities: $10 Million No Legal Framework for Phosphorous Credit / Trading System at this time Barriers to Regionalization

23 Lessons Learned The regulations will not be going away, but you can try to extend the timeline for compliance Treat the first flush Low cost solutions still provide benefit Detailed stormwater mapping and plan information is very important Infiltration is the most cost effective method for pollutant removal
