Trott Brook Crossing EAW August 2021 runoff or infiltration. Buffers will be provided around avoided wetlands, which will preserve wetland functions and values over time. b) 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. 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. Trott Brook (MN DNR Public Waterway M-063-001.5) is located on the southern portion of the site. There is an existing trail stub in a residential development on the south side of Trott Brook that was intended to extend northward onto the Trott Brook Crossing site. The proposed trail connection is anticipated to consist of an approximately 8-foot wide bridge that will facilitate pedestrian traffic between residential neighborhoods and the City of Ramsey. The proposed bridge may include a boardwalk within the wetland fringing Trott Brook to minimize wetland impacts. The pedestrian trail crossing is not anticipated to impede watercraft usage within Trott Brook. The proposed project is not expected to affect and other surface water features such as lakes, streams, ponds, intermittent channels, or county/judicial ditches. 12. 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 ground water contamination, abandoned dumps, closed landfills, existing or abandoned storage tanks, and hazardous liquid or gas pipelines. Discuss any potential environmental effects from pre project site conditions that would be caused or exacerbated by project construction and operation. Identify measures to avoid, minimize or mitigate adverse effects from existing contamination or potential environmental hazards. Include development of a Contingency Plan or Response Action Plan. The majority of the project area has been in agricultural use since at least the 1930s and the remainder has consisted of woodland and grassland. The project area does not include any known pipelines, transmission lines, or registered storage tanks. The site is not known to include environmental hazards and the agricultural land use history suggests a low potential for environmental contamination. The project area is not known to include previous building sites, disposal areas, storage tanks or pipelines. What's in My Neighborhood Review of MPCA and Minnesota Department of Agriculture (MDA) "What's in My Neighborhood" (WIMN) interactive website initially showed 51 observations of potential contamination sites at two locations on the western portion of Trott Brook Crossing. However, upon further review of the potential contamination site details, 33 of those sites were located outside of the City of Ramsey and 20
