wsb <br /> Final Technical Memorandum <br /> To: Michael Grochala, City of Lino Lakes <br /> From: Jon Christensen, WSB <br /> Date: April 28, 2025 <br /> Re: Wastewater Management— 1-35 E Corridor AUAR <br /> City of Lino Lakes, Minnesota <br /> WSB Project No. 027919-000 <br /> INTRODUCTION <br /> The original Alternative Urban Areawide Review (AUAR)was completed and approved in <br /> September 2005. The AUAR analyzed the wastewater impacts of the three development <br /> scenarios. Based on the analysis, a Mitigation Plan was developed. <br /> 0 <br /> 0 <br /> 6 AUAR updates are required every five years from the original date of the approved AUAR. <br /> w Updates were prepared in 2010, 2015, and 2020. Each assumed no change in the proposed <br /> development land use scenarios and included discussion of mitigation improvements that had <br /> been completed at the time. Since the 2020 update, the City has adopted its 2040 <br /> Comprehensive Plan. This AUAR Update reviews two scenarios. <br /> co <br /> The information and analysis outlined within this memo is intended to complete a portion of the <br /> M AUAR Update related to Item # 11.b.i—Water Resources—Wastewater related to revising of the <br /> three scenarios. This memo is intended to update the wastewater analysis provided in the original <br /> AUAR where applicable. <br /> WATER RESOURCES—WASTEWATER <br /> z <br /> Describe effects from project activities on water resources and measures to minimize or mitigate <br /> the effects in Item b.i. through Item b.iv. below. <br /> 0 <br /> a <br /> W i. Wastewater-For each of the following, describe the sources, quantities and <br /> Z composition of all sanitary, municipal/domestic and industrial wastewater produced or <br /> treated at the site. <br /> 1) If the wastewater discharge is to a publicly owned treatment facility, identify <br /> o any pretreatment measures and the ability of the facility to handle the added <br /> LU water and waste loadings, including any effects on, or required expansion of, <br /> 7) municipal wastewater infrastructure. <br /> 2) If the wastewater discharge is to a subsurface sewage treatment systems <br /> W (SSTS), describe the system used, the design flow, and suitability of site <br /> z conditions for such a system. <br /> LU 3) If the wastewater discharge is to surface water, identify the wastewater <br /> a treatment methods and identify discharge points and proposed effluent <br /> Z limitations to mitigate impacts. Discuss any effects to surface or groundwater <br /> X from wastewater discharges. <br /> 0 <br /> MA027919-000\Admin\Docs\Water Wastewater\MEMO Wastewater 2025-02-14 Scenario 3 removed.docx <br /> Page 90 of 240 <br />
