16. Stormwater: GIS and TMDL Monitoring TMDL monitoring for the MS4s will be pendant on the specific type of TMDL. There are three protocols: Visual Stream Assessment and Inventory - based on EPA’s and NRCS’s visual assessment protocols and is being developed by Jimmy Smith and John Burr. The basics in the assessments will be the identification, documentation and prioritization of the sources of the pollution within the entire HUC 12 watersheds within a 5- year period. RBP3 protocol - strait from our SOP/QAPP and will include at least one sample per HUC 12 in a 5-year period. Chemical and biological - also from our SOPs/QAPP, utilizing the identified parameter lists and methodologies and will include 1 set of samples (12 monthly/4 during high flow) per 5-year period.

20. What is Low Impact Development? Comprehensive, landscape-based approach to sustainable development Set of strategies to maintain existing natural systems, hydrology, ecology Cost-effective, flexible approach based on a toolkit of simple techniques Collection of practices that have been implemented nationwide

21. WHY DO WE NEED LOW IMPACT DEVELOPMENT? Conventional strategies aren’t working Increased runoff & decreased recharge Loss of vegetation and wildlife habitat Loss of community character Polluted waterways Cost of development

22. Typical pre-development conditions: Runoff = 10% Infiltration = 50% WHY DO WE NEED LOW IMPACT DEVELOPMENT?

23. Typical post-development conditions: Runoff = 55% Infiltration = 15% WHY DO WE NEED LOW IMPACT DEVELOPMENT?

24. LID PRINCIPLES Use existing natural systems as the integrating framework for site planning Land use planning and watershed planning Identify environmentally sensitive resources: wetlands, mature trees, slopes, drainageways, permeable soils, waterway buffers Assess existing hydrology Define a development envelope

30. Buildings and Roadways LID STRATEGIES Low Impact Site Design Cluster buildings within the development envelope Design buildings with smaller footprints Roadways should follow existing grades. Use parking structures Separate parking areas

31. Stormwater Management LID STRATEGIES Low Impact Site Design Minimize directly connected impervious area Create multiple sub-watersheds Increase time of concentration Use a “treatment train” of LID techniques to deal with frequent, low- intensity storms.

34. Municipal GIS Applications What GIS assistance would local governments like to have from the State? Among other things, an easily accessible clearing house entity that coordinates lists, locations, and links to the various GIS datasets, etc. that different groups within state government have produced. Without such a source, local governments don’t know “what they don’t know”. That is, they don’t know what is available, or who has it.
