iv. Surface Waters 1) Wetlands — Describe any anticipated physical effects or alterations to wetland features, such as draining, filling, permanent inundation, dredging, and vegetative removal. Discuss direct and indirect environmental effects from physical modification of wetlands, including the anticipated effects that any proposed wetland alterations may have to the host watershed, taking into consideration how current Minnesota climate trends and anticipated climate change in the general location of the project may influence the effects. Identify measures to avoid (e.g., available alternatives that were considered), minimize, or mitigate environmental effects to wetlands. Discuss whether any required compensatory wetland mitigation for unavoidable wetland impacts will occur in the same minor or major watershed and identify those probable locations. The City of Ramsey requires a 16.5-foot buffer around all wetlands and stormwater ponds. The wetlands must be protected from disturbance and erosion during the construction process. Post construction, certain activities shall be prohibited within 16.5 feet of the wetland edge. The freshwater emergent wetlands on the site will be avoided, maintaining the existing function and value of the wetlands. If designs would change to impact wetlands, any wetland impacted would require Minnesota Wetland Conservation Act (WCA) approval with the City of Ramsey as the WCA LGU, and an US Army Corps of Engineers (USACE) Section 404 of the Clean Water Act permit. Wetland impacts would be mitigated based on current rules and requirements from the City and USACE. 2) Other surface waters — Describe any anticipated physical effects or alterations to surface water features (lakes, streams, ponds, intermittent channels, county/judicial ditches) such as draining, filling, permanent inundation, dredging, diking, stream diversion, impoundment, aquatic plant removal, and riparian alteration. Discuss direct and indirect environmental effects from physical modification of water features, taking into consideration how current Minnesota climate trends and anticipated climate change in the general location of the project may influence the effects. Identify measures to avoid, minimize, or mitigate environmental effects to surface water features, including in -water Best Management Practices that are proposed to avoid or minimize turbidity/sedimentation while physically altering the water features. Discuss how the project will change the number or type of watercraft on any water body, including current and projected watercraft usage. No alternations to other surface waters are anticipated. 13.Contamination/Hazardous Materials/Wastes a. Pre -project Site Conditions — Describe existing contamination or potential environmental hazards on or in close proximity to the project site, such as soil or Haviland Fields EAW 16 July 2023
