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