Inventory + Data Collection - 21% Flashcards
brownfield sites - regulation
state enviro agencies in cooperation with the EPA regulate investigation and clean up - fed and state grants often available
urban infill sites - regulation
primarily local govt or govt entities - use comprehensive plans, tax benefits, and other incentives
grayfields - definition
underutilized or abandoned retail and commercial sites in urban and usburban areas - think lg bldgs surrounding by parking and little/no vegetation
greenfield - definition
not previoiusly developed or extensively graded
prime farmland - authority
NRCS - National Resource Conservation Service
wetlands - definition
Clean Water Act - areas inundated or satured by surface or ground water at a frequency and duration sufficient to support a prevalence of vegetation typically adapted for life in saturated conditions
floodplain - authority
US Army Corps of Engineers vis Flood Plaing Mgmt Services Program
endangered or threatened species - regulation
Endangered Species Act administered by US Fish and Wildlife Service and NOAA
site inventories - purpose
communicate and map the physical, biological, and cultural components of a site and surrounding area
site inventory - regional checklist for SITES
- EPA ecoregion and major native plant communities
- existing comprehensive community plans and zoning codes
- study surrounds and adjacent site conditions and uses - and impacts - assess factors
- determine important of wildlife of the region, wildlife, habitat, etc
- identify potential for damage from natural disasters
- identify existing and planned public transit, bicycle, or pedestrian systems with 0.25 mi
site inventory - climate and energy - SITES
- avg annual + monthly precipitation, humidity, temp
- potential for renewable strategies
site inventory - microclimate - SITES
- path of the sun, shadows (solar path diagram)
- prevailing wind (study wind rose, meterological data)
- light/dark surfaces that cool/heat like water, pavements, roofs (surface materials, cross check with wind and shadow patterns)
site inventory - hydrology - SITES
- map overland flows and ponding (topo maps)
- estimate rainwater volume and other nonpotable sources avail for reuse (work with Arch)
- map 100-yr floodplan (FEMA flood maps, state agencies etc)
- map existing water bodies, shorelines, veg buffer zones (aerials, site maps, then ground truth, incl guidance on how to determine quality/stability?
- descr exist conditions like habitat quality, bank stability, and artificial modifications
- note ecol restoration opportunities
-locate impaired streams downriver, determine pollutants of concern (research exist drainage infrastructure) - id sources of water pollution and health hazards
- determine seasonal groundwater elevations (impact suitability for excavation, storm- and wastewater mgmt, etc)
site inventory - soils - SITES
- geology + subsoil
- soil type + characteristics - map and field check healthy + degraded (NRCS maps) - typically missing O horizon, and missing or degraded A horizon - when Urban Land Complex, visit site and determine areas of cut and fill by visual inspection
- det any prime farmland, unique farmland per NRCS - National Resource Conservation Service
soils - impacts of geology
suitability for excavation, grading, wastewater disposal, stormwater mgmt, pond construction, etc
soils - area to develop / not develop
- develop areas of degraded soils
- avoid prime farmland, unique farmland, and farmland with soils of statewide importance as they product more efficiently
site inventory - veg - SITES
- veg communities, qualitative inventory, assoc wildlife species, maint/mgmt praces, area to be protected/developed (trees over 6” dbh or per ordinance, heritage/landmark trees, invasive species, other sig veg)
site inventory - veg - techniques
- veg surveys, review aerials
- map veg by parcels en masse, by community, note invasive and old growth
- use timed meander apporach for creating general species lists
- measure woody + herbaceous separately
site analysis - goals
- interpret inventory to correlates areas to best uses, test fasibility, provide framework
- superimpose informational maps (GIS)
