Mr. Michael Grochala April 28, 2025 Pagel Final Technical Memorandum To: Michael Grochala, City of Lino Lakes From: Tim Paquin, WSB Date: April 28, 2025 Re: Greenhouse Gas (GHG) Emission/Carbon Footprint— 1-35 Corridor AUAR City of Lino Lakes, Minnesota WSB Project No. 027919-000 INTRODUCTION The original Alternative Urban Areawide Review (AUAR)was completed and approved in September 2005. The AUAR analyzed the stormwater impacts of the three development scenarios. Based on the analysis, a Mitigation Plan was developed. AUAR updates are required every five years from the original date of the approved AUAR. Updates were prepared in 2010, 2015, and 2020. Each assumed no change in the proposed development land use scenarios and included discussion of mitigation improvements that had been completed at the time. Since the 2020 update, the City has adopted its 2040 Comprehensive Plan. This AUAR Update reviews two scenarios. The information and analysis outlined within this memo is intended to complete a portion of the AUAR Update related to Item # 17.a. and 17.b. —Greenhouse Gas Emission/Carbon Footprint related to revising of the two scenarios. This memo is intended to update the climate analysis provided in the original AUAR where applicable. GREENHOUSE GAS (GHG) EMISSION/CARBON FOOTPRINT GHG Quantification:For all proposed projects, provide quantification and discussion of project GHG emissions. Include additional rows in the tables as necessary to provide project-specific emission sources. Describe the methods used to quantify emissions. If calculation methods are not readily available to quantify GHG emissions for a source, describe the process used to come to that conclusion and any GHG emission sources not included in the total calculation. Analyses for GHG emissions for the study area under existing conditions, Scenario 1, and Scenario 2 were prepared; each is shown in Appendix A. Project-specific emission sources and references to the methods used to quantify emissions are included within the calculation tables in the appendix. GHG Assessment i. Describe any mitigation considered to reduce the project's GHG emissions. During this phase in site planning, plans are concept-level; exploration and development of potential mitigation practices is dependent on further development planning and design. Proposed land use change scenarios increase housing density and availability of shops and live-work units. The existing 35 E Park and Ride within the area can accommodate increased density and encourage non-vehicle travel which would reduce M:\027919-000\Admin\Docs\Greenhouse Gas\MEMO GHG 2025-02-24.docx Page 154 of 240
