Item 20. Other Potential Environmental Effects(Cameran Bailey, 651-602-1212) Urban Heat Island Effect –The proposed development maintains the existing urban heat island (UHI) effect, which increases the demand on the electrical grid to meet cooling load requirements, increases the cost of living due to higher cooling load demands, exacerbates the impacts of heat waves, and increases the vulnerability of the humans most at risk to such heat events-those 65 and older (MN Dept. of Health “MN Climate Change Vulnerability Assessment”, page 20). Decreasing the site’s impervious surface footprint by 2 acres is commendable, but marginal relative to 13.53acres which will continue to be impervious. o The project proposer should consider mitigation of UHI effects by installing green roofs, cool roofs, planting and maintaining trees, incorporating trees into site design, and constructing cool, reflective, and permeable pavements (Metropolitan Council, “Keeping Our Cool: Extreme Heat in the Twin Cities Region”). Such measures would also be in line with a resilience goal in Roseville’s 2040 Comprehensive Plan: “Take action to equitably reduce climaterelated risks to City residents.” GHG Mitigation –The proposed development will maintain a large electrical and natural gas density of consumption, which will continue to drive greenhouse gas emissions, which drive climate change, and the negative environmental impacts that come with it. o The project proposershould consider the integration of green roofs and trees into the site design as they increase energy efficiency, decrease operating and living costs, and decrease the consumption of electricity and natural gas on site. o The project proposer should consider the integration of solar photovoltaic (PV) systems into the rooftop design and utility of the proposed development, as well as into the surface parking lot design. Approximately 5 acres of surface parking can accommodate the development of 5 megawatts ofsolar electricity production. Five megawatts of annual electricity production would meet the annual electricity needs of the 565 proposed units more than twice over. Such implementation would be in line with two resilience goals in Roseville’s 2040 Comprehensive Plan: “Examine opportunities to allow and encourage solar installations within public and private parking lots.”; “Strive to produce enough solar electricity within City boundaries to meet 10 percent of citywide electricity use by 2030, which aligns with Minnesota’s solar energy goal (M.S. 216B.1962).” Forecasts(Todd Graham, 651-602-1322) The EAW describes a redevelopment with seven commercial buildings (totaling 550,000 square feet of floorspace) and three residential complexes (505 housing units). The site is in TAZ #1859. The City’s TAZ allocation, submitted with its 2040 Comprehensive Plan, expects growth of 147 households, 390 population, and 700 jobs during 2020-2040. Should this development proceed, the TAZ #1859 allocation for 2030 and 2040 must be increased. Council staff recommend adding 350 households and 550 population on top of the current allocation. The increase can be offset with reductions in zones elsewhere in Roseville. A forecast change to the City total is not necessary at this time. The TAZ table can be revised through correspondence with Council staff, separate from a formal review process. Page -3|May 6, 2020|METROPOLITAN COUNCIL
