NEARC Fall 2015 has ended

Welcome to the technical sessions schedule for the 2015 Annual Fall NEARC Conference. 

 The technical schedule is capable of being sorted by date (i.e, Monday, Nov. 9) or track (i.e. USGS Hydro). You can also search for a presentation title (i.e. Harmonizing the NHD and WBD Datasets in Maine), key term (i.e. NHD), or presenter last name (i.e. O’Neil-Dunne). The sort and search functions can be found on the navigation panel on the right side of this page. If you hover over the "Schedule" button, you’ll also see different schedule view options (i.e. Grid or Simple). Try selecting each of them to see which view you prefer. 

MY SCHEDULE FEATURE: It is not required of you to create a Sched.org account to use this site but if you do so, you’ll be able to use the "My Schedule" feature which allows you to create your own schedule for the conference. Click the "Sign Up" button in the top right corner of this page to create a Sched.org account.

In order to comply with the federal Clean Water Act, many municipalities throughout New England are or will soon be required to map catchment areas that contribute stormwater to each outfall owned and operated by the municipal storm sewer system. System operators are further required to analyze polluting land uses and the potential for illicit discharge within each catchment area, and the water quality of receiving waters, in order to prioritize pollution reduction efforts. To reduce redundancy of effort and account for the varied data resources available in different municipalities, the Metropolitan Area Planning Council (MAPC), in partnership with the Neponset River Watershed Association, developed a regionally applicable method to conduct this analysis requiring a bare minimum of local stormwater infrastructure data in a standardized format. This basic process for this method is to 1) modify publicly available high resolution digital elevation models (DEMs) to be more hydrologically accurate, 2) use the DEMs to calculate small watersheds for each catch basin, and 3) merge the catch basin watersheds by outfall. MAPC created and published a set of ArcGIS tools available as a free download to municipalities and their contractors to help automate this process to promote a simple and cost effective method to determine outfall catchment areas.
