TCAAP AUAR Update 4 August 2019 3. Development Scenarios There have been no changes to the development scenarios since the 2014 AUAR. The two development scenarios are outlined in Table 1. Table 1: Development Scenarios Component Zoning Scenario Maximum Development Scenario Residential Units 1,500 2,500 Retail (square feet) 500,000 550,000 Non-Retail Commercial (square feet) 1,700,000 1,950,000 4. Impact Analysis Analysis of the development scenarios focuses on land use; water resources; contamination, hazardous materials, and solid wastes; fish, plant communities, and sensitive ecological resources; and transportation. These were the issues that required specific mitigation measures as noted in the 2014 Final AUAR or that had changes in applicable regulations. For other issue areas, the analysis that was completed in 2014 remains valid. The issue areas with no anticipated changes in impacts or mitigation are listed in Section 4.1. Areas with updated analysis or regulatory context are included in Section 4.2. 4.1. Areas of No Anticipated Change No changes are anticipated for the following areas within the 2014 AUAR: • Cover types • Geology, soils, and topography/land forms • Historic properties • Visual • Air • Noise • Cumulative potential effects • Other potential environmental effects 4.2. Areas Requiring Updates 4.2.1. Land Use The 2014 AUAR referenced the City of Arden Hill’s 2030 Comprehensive Plan, which was approved in September 2009. The 2030 Comprehensive Plan was amended in December 2016 to reflect the TCAAP Master Plan, which was approved by the City of Arden Hills in July 2015 and by Ramsey County in January 2016. The comprehensive plan amendment refined the future land uses identified in the AUAR study area from two future land use categories (Mixed Residential and Mixed Business) to 10 (see Table 2).
