Haviland Fields Development Finding of Facts and Record of Decision 10. Ben Flake (August 30, 2023) 11. Rick Bailey (August 22, 2023) 12. Logan Lewis (August 30, 2023) The following sections provide a summary of these comments and responses to them. See Attachment A for the comment letters. Agency Comments and Responses Agency Metropolitan Council Comment Our Water Resources reviewers have determined that the EAW — Haviland Fields is Incomplete because the EAW doesn't discuss water supply. The following is needed before an EIS determination is made: Our Water Resources reviewers have determined that the EAW — Haviland Fields is Incomplete because the EAW doesn't discuss water supply. The following is needed before an EIS determination is made: The EAW does not include information under the water appropriation section regarding the water supply source. If connecting to the municipal system, please ensure the water demand for the development can be met and aligns with the Ramsey local water supply plan. The project is adjacent to a city of Ramsey drinking water supply management area (DWSMA). Source water protection objectives and activities are outlined in the Ramsey wellhead protection plan. The project would benefit by considering source water protection goals and strategies during the development and post - development activities on site. The wetland within the project area is mapped as having a connection to underlying aquifers and is surrounded by sandy surficial deposits. Any contaminants that enter the ground on site may move relatively easily to the wetland and underlying groundwater system. Two domestic wells have been identified on site. Sealing these wells according to MDH guidelines is essential to protect groundwater and water supplies. Additionally, 2 storage tanks are identified on site. The recommended Phase 2 subsurface investigation should be conducted. Tank removal and remediation would benefit nearby source waters. The EAW mentions repurposing these wells for irrigation on site. This activity should be evaluated to determine if the wells are in condition to meet the irrigation demands. Potential impacts on the groundwater source and related connection to the nearby wetland should also be considered. To avoid the need for irrigated water from a groundwater source on site or from a treated municipal supply, on - site reuse options should be explored. Sites planted with native drought tolerant landscaping require less water and fertilizers than turfgrasses. In areas planted Response The water supply will be obtained from the City of Ramsey's water system, which is a groundwater based public water supply. Water mains to service the site area provided within adjacent roadway right-of-way, and a preliminary review indicates that the existing infrastructure is sufficient for the anticipated development. The City is in process of building a new water treatment facility that is anticipated to be online late 2024. This has been added to the EAW in Attachment B. Comment noted. Water protection goals and strategies will be evaluated and implemented as appropriate as design plans are finalized. Comment noted. Effective erosion prevention and sediment control practices will be implemented and maintained near the water resources on site throughout the duration of the project. Comment noted. The proposed plan is to abandon and seal per MPCA/MDH requirements and connect to the City water system. Comment noted. These factors will be considered when deciding if the wells can be used for irrigation. 4
