GIS Tools Accuracy Target Audience Value Added This proposed project uses statewide data sets so it could be used anywhere in the state of Pennsylvania For the sake of working on a smaller scale, Lancaster County was selected as a good candidate for having lots of agricultural lands and subsequent stream impairments
-image shows Lancaster County municipalities and agricultural land use It is expected that this project will be on the level of the individual land parcels.
For this presentation, it will be demonstrated on the municipal level. This proposal will focus on Paradise Township in Lancaster County. It is composed mostly of farm lands and all of it's streams are impaired for nutrients and sedimentation for agriculture. County And Municipality Shapefiles
Stream Attainment Shapefiles Downloaded from pasda.psu.edu Lat and Long database of previously completed PADEP riparian forest buffer projects Lat and Long database of agricultural landowners in study area OpenStreetMap
World Imagery Basemaps provided by ESRI X,Y Coordinates Shapefiles Rasters -Proper projections will be ensured based on Paradise Township Study Area layer
-Environmental settings (output coordinates, mask and extent) will be set to "Same as Paradise Township" Study Area, cell size set to 30
-Coded values in Raster analysis
Any unused variables will be set to NoData
-Buffers created will be verified by using measurement tools -Canopy Raster and Landuse raster can be checked for
accuracy by comparing them to aerial imagery from Google Earth or the Imagery ArcGIS basemap used in this project
-consult with conservation district specialists for accuracy of landuses and canopy -Ground truthing candidate Buffer areas to test slope and soil.
-Visit candidate farmers and verify the results match their actual landuse.
-Verify that candidate areas match PADEP stream impairments for siltation and nutrients Farmers Farmers and landowners are the key to the success of riparian forest buffers. Showing the benefits and providing evidence that their land is suitable for buffers and necessary associated costs Government Agencies DEP and Conservation Districts who are required to impliment Best Management Practices in an effort to remediate streams Watershed Organizations Landowners/Farmers -Using stream impairment listings, this project provides an invaluable tool of where best to focus limited resources on remediation projects for Non Point Source Pollution
-can calculate costs per acre of buffer conversion when planning for future remediation projects
-provides maps to conservation districts and watershed groups when applying for state and federal grants
-Help local governments plan how to comply with Chesapeake Bay or local TMDLs Point Source Dischargers Pennsylvania has over 86,000 miles of streams and rivers Land managers use BMPs (Best Management Practices) as tools to reduce the pollution from non point sources This proposal will use GIS to help identify the ideal locations in Pennsylvania for the placement of riparian forest buffers Created by Gary Gocek Communicating the end product -Peer reviewed technical paper describing the methodology and usefullness of this project to non point source impairment remediation
- maps created and easily added online with web apps and published web services Full metadata that includes a detailed abstract, purpose, process descriptions, source information of all datasets and proper citation Will assist local and state government officials by appearing at public meetings and answer any questions from landowners related to this project Will be available to consult with government employees or conservation district specialists who want to expand this project or add different variables to buffer site selection Local Governments Watershed groups who have an interest in using this information to apply for grants for stream remediation Provides land and stream information on a municipal level will allow local governments to focus their limited resources in the right places. provided by PADEP Land Use Raster Data
Canopy Cover Raster
Digital Elevation Map (Slope) -19% of which are impaired and do not meet their designated uses -Sedimentation and nutrient impairments from agriculture are responsible for most of the non point source pollution in PA BMPs include no till farming, cover crops, stream bank fencing and riparian forest buffers Riparian forest buffers are the most effective BMP in protecting the health of a waterway Benefits of buffers include:
-storing and transforming nutrients
-providing canopy cover
-providing a food source for aquatic life
-provides habitat for birds, mammals and amphibians It's also proposed that once the location is found, GIS can also be used to calculate the cost for converting acreage of agricultural land to forest riparian buffers photo from PADEP's Riparian Forest Buffer Guidance Downloaded from pasda.psu.edu Soils shapefile (soil type) provided by PADEP provided by Lancaster County Conservation District - Map created provides a visual extent of how much of their land will be converted to buffer
-knowing cost per acre(provided by PADEP) landowner can calculate the total expense of a buffer project on their land Local and State Governments -provides a map for point source dischargers who participate in nutrient trading programs to ofset their stream impacts by paying for BMPs in non point source areas Stream and Bay Water Quality -Adding buffers will reduce the amount of nutrients and sediment in near field streams and Chesapeake and Delaware Bays images shows Paradise Township streams with 150 foot buffers. Tan raster is ag land. Blue raster is absence of canopy cover -Landowners XY coordinates provided by conservation district and previous riparian forest buffer projects will be plotted
-Using Select by Location (Paradise Township shapefile) will provide names of landowners and previous DEP projects -Merge attaining and impaired streams shapefile into one complete PA stream layer
-Clip the soils and stream shapefiles using the Paradise Township study area boundary
-Create 150 ft buffer around Paradise Township Stream layer
-Convert the buffer and soil vectors to Rasters using Feature to Raster in Conversion Tools
Rasters Reclassified = 1 (all unused varibles=NoData)
-Slope >5% (Created using DEM and Spatial Analyst)
-Landuse - Agricultural Land
-Canopy - No Canopy
-Soil Type - Soils minus sandy or clay types
-Buffer Raster - Buffer Area
Use Raster Calculator To find appropriate buffer sites
-Using field calculator and cell size, Area of buffer projects can be calculated and converted from m to acres
-Field Calculator uses area and cost per acre figure to find total expense of buffer project provided by PADCNR Where are the best agricultural locations for
the placement of riparian forest buffers in PA?
How much will they cost to implement?
