5 Sustainable Rest Areas Study Goals Conceptualize sustainable and renewable actions and features to rest areas Reduce rest area operation and maintenance costs. Actions that will be adopted by all CDOT Regions Conserving finite natural resources Evaluate carbon footprint and major sources Improve the visitor experience in Colorado

6 Methodology Selected six CDOT rest areas Team members assigned rest areas Literature search of sustainable actions Developed field evaluation checklists Materials and Reuse/Recycling Environment/Site Conditions Air Quality Water Quality/Usage Energy Public/Motorist/Trucking Outreach Created a rest area database Performed rest area sustainability scoring Data review and report development

7 Project Rest Areas Sterling Rest Area Visitor Center/Region 4/Plains Poudre Rest Area Adjacent to Visitor Center/Region 4/Plains Vail Pass Rest Area Recreational Rest Area/Region 3/Mountain Pass Area Hanging Lake Rest Area Recreational Rest Area/Region 3/Canyon Area El Moro Rest Area Basic Services/Region 2/Plains Area Cortez Rest Area Basic Services/Region 5/Desert

17 Carbon Footprint Scope 1- Direct Emissions Scope 2- Indirect Emissions Scope 3- Other Indirect Emissions Using GHG Protocol methodology Carbon footprinting 6 project rest areas Estimated for all CDOT rest areas combined

18 Carbon Footprint Results Sterling = 3,006 metric tons CO 2 e/year. Poudre = 2,517 metric tons CO 2 e /year El Moro = 2,281 metric tons CO 2 e/year Vail Pass = 886 metric tons CO 2 e /year Hanging Lake = 143 metric tons CO 2 e /year Sleeping Ute Mountain = 73 metric tons CO 2 e/year Estimated rest area emission= 36,394 metric tons CO 2 e/year

25 Cost Effective Actions Water Conservation Conduct audits Track water usage Evaluate urinal/toilet flushing volumes Explore waterless urinals ($) Explore water harvesting ($) Reduce lawn irrigation (or eliminate) Modify landscaping Reduce lawn areas (reduces mowing) Native vegetation (reduces water) Increase number of trees (carbon and shading)

26 Cost Effective Actions Electricity Movement sensors for interior LED lighting Timers/sensors for parking area lights Over lighting versus security Energy Star Hand Dryers Evaluate if air condition really needed Natural ventilation/tree shading Alternative Energy Options Solar Heat Pumps

27 Cost Effective Actions Hot Water Heating Determine if really needed On demand heating Solar hot water heating Solid Waste Management Compaction ($) Recycling program Evaluate need for soda vending machines Compost/mulch grass clippings

28 Other Sustainable Actions Community Involvement Recycling Volunteering/Holiday Coffee Local Information Signage Potential Partnerships Environmental Buffer zones Integrated Noxious Weed Management Green Procurement Purchasing Idling Restrictions for trucks

29 Rest Area Sustainability/Alternative Energy in CDOT ROW as/view Art Hirsch-TerraLogic

30 Vail Pass Rest Area Observations/Recommendation s Rest room area built into hill; innovative design No irrigation for landscaping; native vegetation maintained Use State of Colorado Procurement listing of green-low VOC chemicals for cleaning, painting and adhesives Develop stormwater/snow best management practices Install light intensity detectors to reduce daytime lighting Provide signage to the public to educate them on the sustainable operation of the rest area and environmental sensitivity

31 Hanging Lake Rest Area Observations/Recommendatio Water conservation studies (rest nsrooms, lawn irrigation) Native vegetation as a buffer from Colorado River Transition blue grass to a xeriscape landscaping Eliminate the routine application of fertilizers and herbicide Provide waste recycling containers to public Install stormwater/snow best management practices

32 Sterling Rest Area Observations/Recommendations Perform water conservation study Reduce landscape watering of buffalo grass Use mulch mowers to reduce solid waste Only rest area to offer recycling to public Uses electric vehicle for maintenance activities Reduce long term truck parking and idling from CDOT rest areas; evaluate truck electrification Evaluate use of waterless urinals to conserve water

33 Sleeping Ute Mountain Rest Area Observations/Recommendations Reduce toilets/urinals flushing volumes Plant additional vegetation in sparse areas Landscape with native species or xeriscape Eliminate the routine use of fertilizer and herbicide on lawn Motion detector in rest area to conserve energy

34 El Moro Rest Area Observations/Recommendations Place restrictions on idling times or provide electrification Transition from bluegrass to xeriscape landscaping Provide recycling containers Reduce mowing of native plants east of walking path Evaluate waterless urinals and water harvesting

35 Poudre Rest Area Observations/Recommendations Provide recycling containers Place restrictions on idling times or provide electrical hookups Reduce water amounts in toilets/urinals Open fencing promotes wildlife mobility Landscape with native vegetation or xeriscape Evaluate alternative energy options
