The Village, LLC Redevelopment EAW – Record of Decision City of Saint Anthony Village WSB Project No. 2170-380 Page 3 from this proposed development but there are some existing differences in the City of Saint Anthony Village’s system that will need to be addressed to provide the desired increase in levels of service. Any deficiencies in the system will be addressed at the time of preliminary plat review for the redevelopment. The available flow rate for building’s fire system at the proposed location is approximately 2,300 gpm which is below the Insurance Service Office (ISO)’s requirement. Since the City’s existing water main does not have sufficient capacity to supply the development with required ISO fire flow rate, the City of Saint Anthony Village’s existing trunk main may require upsizing or a booster station may need to be installed to increase pressure. This will be determined upon the review of the preliminary development plan. There is an existing water main easement running through the site that will need to be vacated and re-located as part of the development proposal. Water Quality – The project will increase impervious surface area and the rate of runoff at the project sites. Existing runoff drains to a depression in the southeast quadrant of the project area and discharges to the Saint Anthony Village stormwater system. The stormwater is then discharged into the City of Minneapolis system and into the Mississippi River. City Stormwater System currently surcharges and flows back into this property. Therefore, backflow preventers may be required to manage stormwater runoff onto this site. This will be determined upon the review of the preliminary development plan. Stormwater quality requires the capture and retention of the first 1.1 inches of runoff from the new and fully reconstructed impervious surfaces. However, due to the presence of clay soils and the potential for mobilization of contamination, infiltration is discouraged on this site. Therefore, if the site is unable to capture and retain the 1.1 inches the site must meet the Mississippi River Watershed Management Organization Watershed Management Plan standards. Any deficiencies in the system for the development will be addressed at the time of preliminary plat review for the redevelopment. The one existing storm sewer connection between the project site and Kenzie Terrace will need to be reviewed and permitted by Hennepin County. Potential Environmental Hazards – An underground storage tank (UST) was located at project site but was removed in 1986. A site leak was discovered in 2012 and consisted of fuel oil 1 &2. The leak impacted groundwater. The leak was issued site closure by the MPCA in 2013. Site closure means that the leak does not pose a threat to human health or the environment but the site is not necessarily free of contamination. If excavation is proposed in the vicinity of this site, there is a potential for encountering petroleum impacted soils and/or groundwater will be encountered from the leak. Based on current information, the potential for this is high. Phase I and II Environmental Site Assessments (ESAs) were completed for the project area in 2012, and two additional Phase II investigations were completed in 2016. In 2016, various volatile organic compounds (VOCs), and tetrachloroethene were detected in soil vapor at the project site at levels higher than residential intrusion screening values. Diesel range organics (DROs) were detected at concentrations above the MPCA’s criteria for unregulated fill. Diesel range organics and 22
