Aesthetics Preservation of Views Develop materials and designs that blend into the environment.        
Specify roadside signs that meet the AASHTO standards but also respond to the local cultural and environmental context.        
Identify important natural features that should be preserved within the clear zone and jointly develop strategies to preserve these features.        
Develop blowing-snow mitigation designs that are safe and visually appealing.        
Determine the impact of vegetative clearing on the local environment.        
Specify plants that will enhance views from the roadway.        
Identify flora to be preserved in the clear zone.        
Specify seed mixes and plantings for water quality features.        
Revegetate with contextually appropriate plant species.        
Specify materials and designs that have an extended lifecycle.        
Develop screening strategies for water quality facilities.        
Develop cut and fill designs that ensure preservation of open vistas and view corridors.        
Mitigate the visual effect of cut and fill on the local roadside environment.        
Construct retaining walls that blend into the natural context.        
Ensure that rock fencing has the least amount of visual impact.        
Category Subcategory Measure Implemented Considered but Not Implemented Not Applicable to Project Justification/Notes
Geotechnical Materials Ensure that slope angle can be supported by the roadside material.        
Design for mitigation and prevention of future rockfall events.        
Ensure that there is adequate support for structures. Where possible, minimize the area of the ground to be disturbed for the excavation.        
Ensure that if vegetation is used to anchor soil, that it is designed for the long term and will minimize encroachment.        
Ensure that little to no irrigation is needed after initial plant establishment.        
Consider vegetation as a tool that can bolster the palette of geotechnical strategies.        
Check for the design of adequate drainage in wall systems.        
Use local materials for roadside elements (embankments, structures, etc).        
Use recycled materials for roadside elements.        
Stabilize soils with cementitious and recycled materials.        
Category Subcategory Measure Implemented Considered but Not Implemented Not Applicable to Project Justification / Notes
Hydraulic Design General Identify protected and/or sensitive areas along corridor to help establish drainage pattern.        
Use native trees and brush to ensure stable materials, intercept rainfall and slow runoff accumulation.        
Evaluate the balance in slopes to preserve natural environment.        
Evaluate options to handle or divert runoff with wall design.        
Mimic natural flow conditions.        
Minimize visual impact of water quality features and structures.

Category Subcategory Measure Implemented Considered but Not Implemented Not Applicable to Project Justification / Notes
Vegetation Process Define vegetation objectives clearly within the context of the larger project objectives.        
Document physical and environmental features of the site (solar aspect, elevation, slopes, grading, drainage, climate, etc.)        
Develop a vegetation plan. Consider plant establishment, plant sizes/spacing and natural forms of weed control.        
Minimize delivery distance of vegetation needs to the project site        
Minimize the costs of the resources and materials required to establish the plants such as the costs of water, fertilizer, pest control and labor required.        
Document the success of vegetation efforts during post-construction and through long-term operations.        
Habitat Avoid/Minimize/Mitigate Habitat Fragmentation        
Create new habitats where possible and restore or create new connections between habitats.        
Restore/Mitigate Wetlands        
Provide Nesting Locations        
Provide Wildlife Crossings        
Provide Fish Passage        
Schedule Construction to Avoid Wildlife Disruption        
Trees and Plants Avoid impacts to trees        
Design for a net increase in tree species (replacement greater than 1:1 ratio)        
Re-establish/expand native vegetation in reclaimed work areas        
Use native plant material as living snow fences, sight screens, etc        
Design plant groupings to provide contrast and respond to context.        
Remove invasive and undesirable plant species        
Balance cut and fill        
Reduce use of fertilizers and herbicides        
Reuse and preserve topsoil        
Category Subcategory Measure Implemented Considered but Not Implemented Not Applicable to Project Justification / Notes
Maintenance Hydraulic Design Ensure that ditches remain traversable after cleaning.        
Clean ditches and structural features of debris and sediment regularly to prevent them from clogging and backing water onto the travel way.        
Ensure that side slopes do not become eroded over time. Plant native vegetation to slow erosion.        
Avoid drainage features built above the ground which can cause injury if hit. Extend or relocate pipe, culvert and other features.        
Geotechnical Evaluate side slopes for any steepening due to erosion.        
Evaluate any erosion damage around roadside structures such as walls, columns, abutments and drainage structures.        
Evaluate the safety of steep slide slopes for their ability to handle errant vehicles; evaluate the quality of the recovery area (if present) at foot of embankment.        
Vegetation Develop an Integrated Vegetation Management (IVM) plan to set priorities and direct maintenance actions.        
Control invasive weeds.        
Improve soils to ensure long-term plant health.        
Manage living snow fences.        
Maintain clear zones.        
Keep vegetation away from guardrail.        
Safety Maintain guardrail and fencing in good condition; inspect regularly.        
Repair damaged guardrail promptly to ensure safe travel.        
Maintain and repair roadside signs, safety devices, etc.        
Clear litter and collect trash from the roadside.
