Environmental Scoping Guidance

Jerry Vogt

Region Environmental Coordinator

ODOT – Region 3

  • Raise awareness of the potential for environmental permits and clearances
  • Identify the types of permits and clearances that might be required
  • Identify the types of construction activities that may trigger the need for additional study or a permit
session topics
Session Topics
  • Benefits of Environmental Scoping
  • Types of resources that require permits/clearances
  • Activities that trigger permits and clearances
benefits of environmental scoping
Benefits of Environmental Scoping
  • Better cost estimates when preparing grant applications or funding requests
  • Gives project team an idea of the types of environmental disciplines that will be needed
  • Aids in preparation of prospectus Part 3
  • Used in the development of scopes of work for environmental consultants
  • Better avoidance/minimization of impacts
environmental disciplines
Air Quality




Land Use

Hazardous Materials

Historic Resources

Parks 4(f) and 6(f)

Traffic Noise

Socioeconomic/ Environmental Justice

Visual Resources

Water Quality



Other Permits

Environmental Disciplines
environmental disciplines1
Environmental Disciplines
  • The environmental disciplines needed for a project will depend on the size and type of project and the resources present
  • Focus of this presentation is on CatEx projects
air quality
Air Quality

In Air Quality Maintenance or Non-Attainment Area

  • Regional air quality analysis (Usually done by MPO)
  • Project-level air quality analysis
    • Signalization
    • Channelization
    • Add capacity
  • Projects that involve any ground disturbing activities
  • Includes work within existing roadways and previously disturbed areas
  • Surveys include pedestrian, subsurface probing, construction monitoring & data recovery
  • Evaluate impacts to listed species
    • No Effect
    • Biological Assessment
    • Programmatic BO
  • Listed Fish:
    • Work within stream channel will likely require BA or Programmatic BO
    • BA could be needed to assess stormwater impacts
biology continued
Biology, continued
  • Listed Plants
    • Plant surveys are needed for projects involving ground disturbing activities
    • Biological Evaluation and consultation with USFWS needed if project will impact listed plants
  • Listed Wildlife
    • BA needed if project is located within or near critical habitat

Even if project has no effect, documentation is still required to justify determination

floodplain floodway
  • Projects that involve work within a floodplain may require review/approval by local planning department
  • May require hydraulic analysis
land use
Land Use

Projects that:

  • impact protected land use zonings (Exclusive Farm Use, Open Space Reserve, Forest)
  • displace buildings
  • construct new road through resource lands
  • create new land parcels
hazardous materials
Hazardous Materials
  • All projects should be evaluated for the presence of hazardous materials
  • Level of evaluation will be determined by proximity of known sites or probability of contamination of project area
  • Can include asbestos or lead paint on old bridges or in old buildings
historic resources
Historic Resources
  • All projects should be evaluated for historic resources
  • Any buildings, bridges or other structures over 50 years old may be historic
  • Documentation requirements will vary depending on presence/absence of resources and severity of impacts
parks 4 f and 6 f
Parks – 4(f) and 6(f)

4(f) Evaluation needed for:

  • Projects that receive FHWA funding and
  • “Use” parks, wildlife refuges, recreational areas and historic sites

6(f) Evaluation needed for:

  • Conversion of lands that have received LWC funds

These evaluations can require extensive coordination with FHWA, resource managers and National Park Service

traffic noise
Traffic Noise
  • Significant shift in horizontal or vertical alignment of highway
  • Construction of new roadway on a new alignment
  • Removal of noise-shielding topographic features
  • Construction of additional through travel lanes that increase capacity
socioeconomic environmental justice
Socioeconomic/Environmental Justice
  • Benefits of a project should be stated
  • Project should be evaluated to determine if there are disproportionate adverse impacts to Environmental Justice populations (low-income, minority, elderly)
  • Determine if project will disrupt or divide an established community or neighborhood.
visual resources
Visual Resources

Coordination on visual resources may be needed for projects:

  • Within a State Scenic Waterway Corridor (OPRD)
  • Within a Wild and Scenic River Corridor (BLM/USFS)
  • Within a Scenic Byway (BLM/USFS/ODF)
water quality
Water Quality

Stormwater Management Plan

  • Project requires Corps permit
  • Project adds impervious surface area
  • Changes runoff patterns to receiving waterways
  • May need to include both water quality treatment and detention
  • Wetland determination
  • Wetland delineation (for unavoidable wetland impacts)
  • Corps/DSL Permits
  • Compensatory Wetland Mitigation
  • Includes streams, some ditches, irrigation canals, lakes
  • Permits are required for placement of fill material or removal of material (Corps/DSL)
  • Instream Work Period
other permits approvals
Other Permits & Approvals
  • Fish Passage Plan Approval (ODFW)
  • Tree Removal Permits
  • Riparian Vegetation Permits
  • Noise variance for night work
  • Farmland Conversion Impact Rating (NRCS)
  • 1200-C Permit for construction (DEQ)
  • With few exceptions, all Federal Aid projects will require some type of documentation for historic resources, archaeology, biology, Hazmat, and water quality
  • For more information on environmental permits and clearances, refer to the Local Agency Guidelines Manual at:
