PURPOSE AND NEED
Why are we working on Brighton Boulevard?Transform Brighton Blvd into a vibrant place and enhanced travel corridor for all users:• Improve safety for all• Basic infrastructure (e.g. curb, gutter, sidewalk, street
trees and planting areas)• New bike and pedestrian facilities• Burying power lines underground• Design that respects the area’s rich history and new
development

HEAT ISLAND EFFECT
Why is increasing the tree canopy important?Improve aesthetics, water quality and air quality:• One of the highest heat island index areas in the city• Limited drainage improvements and water treatment• Immediately adjacent to the South Platte River• Main corridor to/from downtown and the airport• Integrate larger sustainability goals for the City• Pilot new techniques and begin branding of innovative
treatments and design

DESIGN DETAIL
HOW DID WE GET HERE - COORDINATION
At installation tree canopy – note density
Mature tree canopy – maintained to emulate riparian character of adjacent Platte River corridor

DESIGN DETAIL
HOW DID WE GET HERE - COORDINATION
At installation tree canopy – note density
Added diversity to tree planting palette and created gaps in PLD for placement of larger shade trees

FINAL DESIGN
• Maintenance guidelines
• Annual inspections• Continued study &
potential to refine design/species
• Coordination with GID
What still needs to be done and how will maintenance be addressed?

DESIGN STUDY GOALS
What are the overarching goals for the design effort?
• Define the elements to be constructed within the City Right of Way (sidewalks, bike facility, parking, street lights, drainage, etc.) – ~$26M budget
• Integrate RiNo GID funded enhancements (trees/landscaping, pedestrian/accent lighting, enhanced paving) into a cohesive streetscape– ~$3M budget
