  1. Presented by P.W. Grosser Consulting on behalf of Suffolk County Department of Public Works December 14, 2016

  2. Agenda  Team Introduction  Suffolk County’s Water Quality Initiatives  Sewer Projects Purpose and Goals  Connetquot River Project Facts  Project Timeframe  Preliminary Project Costs

  3. Project Team  Suffolk County Department of Public Works  P.W. Grosser Consulting – Project Lead  CJ2 Communications – Public Relations  Sidney Bowne and B. Thayer Associates – Survey Team

  4. Suffolk County’s Water Quality  Initiatives  In 2015 Suffolk County Completed their  Comprehensive Water Resources Management Plan  Among other projects recommended in the plan four  large sewer project focused around south shore rivers  emerged, including the following:  Carlls River  Connetquot River  Forge River   Patchogue River

  5. Proposed Sewer Projects Goals  Provide sewer service to 11,000 parcels – 465 in Great  River  The four (4) sewer projects remove close to 860  pounds of nitrogen from the Great South Bay  Watershed  Protect Connetquot River

  6. Map of Overall Projects

  7. Purpose of These Projects  Protect Long Islands Sole Source Aquifers from Nitrate  Contamination  Reduce Nitrate Levels in Surface Waters  Reduce Occurrence of Harmful Algal Blooms  Restore Wetland and Seagrass Areas  Improve Coastal Resiliency

  8. Physical Impact of Nitrogen on the  Great South Bay  Caused the GSB to be listed on NYSDEC’s 303(d) list of  impaired water bodies since 2008, restricts its  commercial and recreational viability.  Nitrogen is essential to aquatic plant life; but in excess  can lead to harmful algal blooms that consume oxygen  when the algae die and decompose. The resulting low  oxygen condition (hypoxia) can negatively affect other  plant and sea life populations.

  9. Impact on Hard Clam Harvest In 1976 the price received by fisherman (ex‐vessel price) for the clams commercially  harvested from the Great South Bay totaled $16.9 million, however at modern day  prices the same harvest would yield approximately $63.5 million, according to the  New York State Department of Environmental Conservation. 

  10. Project Description  Comprised of the hamlet Great River  Connect 465 parcels to municipal sewer system  Gravity Sewer System – Will connect to Southwest  Some Pump Stations may be necessary  Remove 41 pounds per day of nitrogen from entering  the groundwater

  12. Land Use Map

  13. Project Timeframe  Survey Work  Initial Control Survey Has Begun  Door to Door Surveys – First Quarter of 2017  Project Website – First Quarter of 2017  Figures and Reports  Meeting Dates and Notices  Engineering Report – Work Has Begun   Next Public Meeting – February 2017

  14. Door to Door Surveys  Notify via mailing and website of scheduled work  Two Man Survey Crews  Will have Photo ID   From B. Thayer Associates   Obtain the Following Information  Topographic Information of the property  First Floor Elevation of your house/business  Sewer Line Invert Elevation  Take Picture of the Property   Leave Flyer on how to measure your sewer line invert  elevation, if you are not home or don’t want to allow the  survey crew access. 

  15. Preliminary Budget Estimates • The “hard costs” for each phase were determined based upon the  preliminary sewer layout and typical construction costs.  The budget estimates also include the “soft costs” for engineering,  surveying and legal fees.  Given the preliminary nature of the design a 15 percent contingency was  also included, to account for unforeseen conditions.  • •

  16. Determining O&M Costs  Comprised of two parts   Per Parcel Charge = $36.00  User Fee = $157.00   Total O&M Fee = $193.00   Based on SCSD # 3 – Southwest 2017 Fees  For users utilizing the LPS and Pump Station   Additional annual O&M for the Pump Station  Electric costs = $50  Optional pump service contract = $500 

  17. Financing and Assessed Value  To determine the annual cost per household, the  available funding options and assessed property value  were utilized.   Funding will be a combination of Grants and loans  from New York State Environmental Facilities  Corporation (EFC), which provides loans at 2 percent  interest for 30 years.   The median assessed value for the study area was  determined to be $65,200, which equates to a property  value of approximately $513,000.

  18. Annual Costs Grant  Percentage Debt Service District O&M Total Amount 0% $2,502 $193 $2,695 25% $1,876 $193 $2,069 50% $1,251 $193 $1,444 75% $625 $193 $818

  19. Economic Impact of Nitrogen  Septic system cost elimination  Improved water quality in Great South Bay and  Connetquot River  Increase recreation and commercial fishing activity.  Improved coastal resiliency  As a result, increased value of property throughout the  study area and along the Great South Bay.
