10. Gateway/Opus Request for and AUAR Environmental AssessmentI CITY OF Jo CHANHASSEN 690 COULTER DRIVE • P.O. BOX 147 • CHANHASSEN, MINNESOTA 55317 (612) 937 -1900 • FAX (612) 937 -5739 Astioa by City Adminfs dot TO: Don Ashworth, City Manager Endorse ✓ TWA- , Re'wte Date Submitted to Commission FROM: Kate Aanenson, Senior Planner -- —" Date t0 L0061 DATE: March 9, 1994 SUBJ: Gateway /Opus Request for an Alternative Urban Area Review Environmental Assessment BACKGROUND The Gateway (Opus) development, located at the southeast corner of Hwy. 5 and 41 was given conceptual PUD approve by the City Council on January 11, 1993. The applicant was required to wait until the Highway 5 Corridor Study was developed and prepare an Environmental Impact Statement (EIS) before additional approvals (preliminary) can be given. This project includes 178 acres and will include over 900,000 square feet of buildings. In the past months, the applicant has sought to revise their plan to incorporate the design issues recommended in the corridor study. The applicant has requested that staff review other options for an environmental assessment rather than an EIS. Staff is in concurrence that the requirement for an EIS, which is precipitated' by the square footage of proposed buildings, is a lengthy process that would not provide any additional information that would be revealed through an Environmental Assessment Worksheet (EAW). ANALYSIS Paul Krauss and the applicant meet with Greg Downing, from the Environmental Quality Board (EQB), and reviewed alternatives for an` environmental assessment.: Mr. Downing recommended an Alternative Urban Areawide Review (AUAR) „process as a mbF- F'ute for an environmental review. The AUAR is a hybrid of the EIS and EAW process. The process uses a standard list of questions like an EAW but provides a level of analysis for typical urban area impacts comparable to an EIS. Because the city has an approved comprehensive plan, we can use the AUAR process. Staff supports the AUAR process for the Gateway project. The boundaries of the project is limited to 184± acres of the Gateway development (Attachment #2). MEMORANDUM 1 I LJ� Don Ashworth March 9, 1994 Page 2 The city will act as the Responsible Government Unit (RGU). The applicant has completed a Phase I Environmental Audit. This will be a part of the AUAR document. The applicant is being asked to prepare the AUAR to address the issues as outlined in the EAW process (see Attachment #3). The city has contracted Strgar Roscoe Fausch, Inc. to complete the traffic element. All other issues in the assessment will be completed by the applicant. RECOMMENDATION Staff is recommending that the City Council adopt the a resolution recommending an Alternative Urban Areawide Review (AUAR) be completed for the property known as the Gateway development as identified on Attachment #2 with the issues addressed and identified in Attachment #3. CITY OF CHANHASSEN CARVER AND HENNEPIN COUNTIES, MINNESOTA DATE: RESOLUTION NO: MOTION BY: SECONDED BY: A RESOLUTION APPROVING AN ALTERNATIVE URBAN AREA WIDE REVIEW (AUAR) PROCESS BE COMPLETED FOR THE GATEWAY /OPUS DEVELOPMENT WHEREAS, on January 11, 1993, the City Council gave conceptual PUD approval for the Gateway /Opus Development located at the southeast comer of Hwy. 5 and Hwy. 41; and WHEREAS, due to the intensity of the development, an Environmental Impact Statement (EIS) is required; and WHEREAS, the developer /applicant, Gateway, is requesting that an Alternative Urban Area wide Review (AUAR) process be completed rather than an Environmental Impact Statement. NOW, THEREFORE, BE IT RESOLVED that the City Council has determined that an EIS will not provide any additional information and directs that an Alternative Urban Area wide Review for the environmental assessment be prepared and submitted by the applicant.
