Preparing Bostons Water and Sewer Systems for Future Design Storms John P Sullivan, P.E. Boston Water and Sewer Commission November 22, 2019 DISCUSSION TOPICS Present Condition & Upgrades to Existing Systems Improved Stormwater

  1. Preparing Boston’s Water and Sewer Systems for Future Design Storms John P Sullivan, P.E. Boston Water and Sewer Commission November 22, 2019

  2. DISCUSSION TOPICS  Present Condition & Upgrades to Existing Systems  Improved Stormwater and Inundation Modelling  Upland Control of Stormwater  Coastal Stormwater Discharge Analysis  Smart Sewers

  4. STORMWATER WATERSHEDS

  5. TIDE GATES MOUNTED ON SEA WALL

  6. NEW TIDE GATES MT. WASHINGTON AVE

  7. WHY ARE TIDE GATES IMPORTANT

  8. Boston Stormwater Management  Total Maximum Daily Load (2007)  Phosphorus: Upper & Middle/Lower Charles River  Consent Decree (2012)  Update Stormwater Model  Create BMP Implementation Plan  Implement 3 Pilot Green Infrastructure/Low Impact Development (“GI/LID”) Projects  Central Square, Audubon Circle, City Hall Plaza

  10. GI/LID Obstacles in Boston Commission does not own land for GI/LID • Need to work with other agencies and entities Department of Public Works – Department of Transportation – Boston Parks and Recreation Department – Boston Public Schools – Boston Planning and Development Agency – • Need to work with private property owners • Need complete understanding of who is responsible for continued maintenance

  18. NEW INUNDATION ANALYSIS

  19. IMPROVED ESTIMATES OF FUTURE FLOODING DEPTHS AND EXTENTS

  20. DETAILED FLOOD DEPTHS AVAILABLE FOR EXTREMELY SMALLER SUB-AREAS

  21. IMPROVED VISUALS FOR ENHANCED PUBLIC UNDERSTANDING

  22. STORMWATER DETENTION IDENTIFY AREAS TO DETAIN STORMWATER DURING EXTREME EVENTS AND POSSIBLY PROVIDE TREATMENT DURING MINOR EVENTS

  23. TOP AREAS FOR POSSIBLE STORMWATER DETENTION

  24. STORMWATER DETENTION WITH PHOSPHOROUS TREATMENT CAPABILITIES

  28. FORT POINT CHANNEL STORAGE

  29. Smart Sewers

  30. CONTINUING FORWARD • INVESTIGATE PIPES THAT NEED TIDE GATES • COORDINATE WITH CITY ON BARRIERS AND THE NEED FOR TIDE GATES TO ENSURE COMMISSION PIPES DO NOT ACT AS BY-PASS TO BARRIER • INVESTIGATE CATCH BASINS THAT MAY DISCHARGE TO COMBINED SYSTEMS IN AREAS THAT MAY BE PRONE TO INUNDATION • CONTINUE TO COORDINATE WITH CITY ON CLIMATE CHANGE STRATEGIES • INVESTIGATE AREAS TO STORE STORMWATER DURING LARGE EVENTS • CREATE INUNDATION MODEL TO IDENTIFY AREAS: THAT MAY NEED TO BE EVACUATED IN EXTREME EVENTS; DISRUPT TRANSPORTATION; IMPACT POTENTIAL EVACUATION CENTERS; IMPACT HEALTH CARE FACILITIES • INSPECT TIDE GATES AND OUTFALLS • MONITOR RAIN DATA TO GATHER INFORMATION ON STORM EVENTS AND INTENSITY • CONDUCT MONITORING ON DORCHESTER INTERCEPTOR • IDENTIFY STRATEGIC MONITORING LOCATIONS AND INSTALL METERS TO GATHER INFORMATION ON HOW SYSTEM RESPONDS TO CHANGING RAIN EVENTS
