STORMWATER & INFRASTRUCTURE MANAGEMENT

HOW TO CONNECT PEOPLE INVOLVED IN THE DAY TO DAY BUSINESS

OF OPERATING AND MAINTAINING INFRASTRUCTURE WITH

NECESSARY INFORMATION?

  • COMPILE RECORD MAPPING
  • WORK WITH STAFF TO DETERMINE NEEDS
  • DEVELOP A DATA DICTIONARY
  • HANDS ON TRAINING AND TESTING
  • LAUNCH AND MANAGEMENT

SITE SUITABILITY ANALYSIS

LAKE GEORGE WATERSHED DATA ATLAS

THE LAKE GEORGE WATERSHED INCLUDES A PORTION OF

SEVERAL MUNICIPALITIES. THIS MAKES WATERSHED- SPECIFIC INFORMATION GATHERING DIFFICULT:

  • THREE (3) COUNTIES
  • ELEVEN (11) TOWNS
  • ONE (1) VILLAGE
  • MULTIPLE US CENSUS TRACTS,

BLOCK GROUPS, AND BLOCKS

SITE SUITABILITY ANALYSIS

ONSITE WASTEWATER TREATMENT SYSTEMS (OWTS)

& WATER QUALITY (E.G., ALGAE)

  • CONCERNS INCLUDE METAL SEPTIC TANKS (THAT

MAY OR MAY NOT BE CORRODED AND LEAKING) AND CESSPOOLS. POSSIBLE FAILURES IN SOIL TREATMENT AREAS (STA) AND SEEPAGE PITS ARE ALSO BEING LOOKED AT, AS WELL OVERALL AGE OF SYSTEMS

  • THERE IS LIKELY A NUMBER OF EXISTING

PROPERTIES WITHIN 500 FEET OF LAKE GEORGE AND 100 FEET OF STREAMS THAT POTENTIALLY NEED RETROFIT OR SOME LEVEL OF REPLACEMENT OF OWTS

GIS OWTS SITE SUITABILITY ANALYSIS:

*Created a 200’ shoreline buffer, which was then divided into 200’ wide segments that corresponded to sample point locations. Each of these segments was assigned the data values of the corresponding sample point.

NEXT STEPS:

  • DEVELOP A WATERSHED OVERLAY DISTRICT THAT PROTECTS KEY NATURAL RESOURCES AND

REQUIRES CONSERVATION BASED DEVELOPMENT

  • INCORPORATE ZONING THAT RESULTS IN REDUCED DENSITIES AS YOU MOVE AWAY FROM

EXISTING DEVELOPMENT*

  • CONTINUE TO MODEL AND ANALYZE EXISTING HYDROLOGY AND STORMWATER AS IT

RELATES TO WATER QUALITY (THIS EFFORT WAS RECENTLY AWARDED TWO GRANTS)

  • DESIGN CENTRAL AND NONCENTRAL GREEN INFRASTRUCTURE TREATMENTS THROUGHOUT

PRIORITY SUBCATCHMENTS

  • IMPROVE EXISTING STORMWATER CONTROLS AND UPDATE TO CURRENT STANDARDS
  • INCREASE STORMWATER DESIGN STANDARDS TO CAPTURE SMALLER PROJECTS
  • WORK WITH NONPROFIT AND EDUCATIONAL COMMUNITY TO ENHANCES WATER QUALITY
