PURPOSE AND NEED STATEMENT The Purpose and Need statement is a brief statement that identifies the reasons for proposing a major transportation improvement project. PURPOSE: The purpose of the Northwest Rail project is to implement fixed guideway mass transit service between Denver, Boulder, and Longmont with the least-environmentally damaging, practicable alternative. NEED: Improve mobility Address increasing congestion Provide effective transit service Provide multimodal travel options Increase trip capacity

SOCIAL/COMMUNITY AND ECONOMIC RESOURCES Relocation of the Boulder Emergency Squad at SH 119 and 47th Street 16 residential relocations 76 business relocations Benefit from improved access to transit within.5 mile from stations A modest increase in density surrounding stations is anticipated Temporary impacts during construction by dust, noise and traffic congestion, and out- of-direction travel Loss of $1 million in annual property tax Create a significant number of jobs during 5-year construction period MITIGATION: Community coordination Construction Management Plan Mitigations identified for: Land acquisition Transportation Noise and vibration Air quality Visual/aesthetic resources

CULTURAL RESOURCES Cultural resources include: Historic Archaeological Paleontological Properties are impacted if they are affected by the proposed project (can be direct or indirect) Anticipate no adverse effects to these resources An adverse effect is found when the proposed project alters a property characteristic that qualifies resource for the National Register of Historic Places (NHRP) Consultation to be with State Historic Preservation Officer on-going Consultation to be completed in conjunction with Final Environmental Evaluation NRHP- ELIGIBLE OR -LISTED PROPERTIES Impacts Number of Impacts to NRHP-Eligible or - Listed Properties and Linear Resources Direct Impacts Indirect Impacts HISTORIC PROPERTIES AND LINEAR RESOURCES ARCHAEOLOGICAL (SITES) 23 1 7 Effects Number of Impacts to NRHP- Eligible or -Listed Properties and Linear Resources Resulting in an 23 Adverse Effect 2 Source: Northwest Rail (NWR) Corridor Project Team, 29. 1 Some linear resources cross the corridor at multiple locations and would be impacted more than once. 2 Impacts and effects presented are preliminary pending formal consultation 3 Both Adverse Effects (5DV3512 and 5AM1885/5DV6243) are to historic properties analyzed through the Gold Line project

WETLANDS AND BIOLOGICAL RESOURCES WETLANDS ANALYSIS Project modified to avoid and/or minimize impacts to wetlands and waters of the U.S. Avoidance and Minimization included Modifying the rail track alignment Modifying station layout Reducing station platform size Modifying station concept plans Eliminating bypass tracks at stations WETLANDS MITIGATION Mitigation will comply with all USACE and RTD requirements/policies. Mitigation consistent with jurisdiction policies. Best Management Practices including mitigation during construction BIOLOGICAL RESOURCES Evaluated the following: Vegetation and habitat Prairie dog colonies Migratory birds Wildlife corridors and movement Noxious weeds Aquatic habitats Special status species Left Hand Creek Rock Creek U.S. Fish and Wildlife Service concurred with findings
