Mr. Michael Grochala April 28, 2025 Page 3 In both Scenarios, increasing residential density may improve ridership and service among the transit route that serve this area. Additionally, in each Scenario, it is assumed that improved trail and sidewalk connections to the surrounding network will be provided. Each Scenario's potential impact on transportation and reduction to single-occupancy vehicle travel is not accounted for in the emissions analysis above. Existing and proposed future sustainability or climate-related City/County programs and greenhouse gas reduction strategies were not explicitly incorporated within the modeling methods; however, incorporating greenhouse gas mitigation measures such as those mentioned above may further reduce greenhouse gas emissions beyond what is provided in the Scenario estimates. iii. Quantify the proposed projects predicted net lifetime GHG emissions (total tons per#of years) and how those predicted emissions may affect achievement of Minnesota Next Generation Energy Act goals and/or other more stringent state or local GHG reduction goals. Minnesota's Next Generation Energy Act requires the state to reduce greenhouse gas emissions in the state by 80% between 2005 and 2050, while supporting clean energy, energy efficiency, and supplementing other renewable energy standards in Minnesota. Within the city's 2040 Comprehensive Plan, among the sustainable energy action items, it is identified that the city aims to: • Protect access to direct sunlight for solar energy systems on principal structures, • Encourage future sites and building plans to maximize efforts to design for efficient use of solar energy including such elements as the location of windows, shade trees (and types), windows, and driveways, • Use where possible solar energy design elements for future public facilities and infrastructure development, and • Encourage and support educational programs and research that focuses on alternative or renewable energy systems Methods for modeling air emissions were completed in accordance with EAW (Environmental Assessment Worksheet) standards. The expected Iifespan of the project is 50 years. The project's predicted net GHG emissions over the project's Iifespan (compared to existing conditions)are estimated at 184,790 CO2e metric tons per year for Scenario 1 or 213,938 CO2e metric tons per year for Scenario 2.
