Motion by Councilmember Jacobsen, seconded by Councihnember Burg to adopt a Resolution that would authorize and accept the Rice Creek Watershed to amend the petition for the New Brighton/St. Anthony Basic Water Management Project, Rice Creek Watershed District Project 2013 -01. 5 Ayes, 0 Nays -Motion Carried 3. Consideration of a Special Use Permit to allow construction and implementation of a revised sound mitigation berm and plan at 2200 Old Highway 8 NW, known as Belair Excavating. Report No. 14-133. City Manager Lotter explained Planning Coordinator Gundlach would be presenting this item to Council. Planning Coordinator Gundlach stated the applicant is requesting a Special Use Permit to allow implementation of a new sound mitigation plan for the property located at 2200 Old Highway 8 NW, known as Belair Excavating. The sound mitigation plan relates to previous land use approvals from 2010 that permitted the aggregate crushing /recycling and yard waste transfer uses per Resolutions 10 -068 and 10 -069. Those previous approvals required construction of a sound mitigation berm north -south along the western property boundary to mitigate onsite noise from spilling over into residential areas to the west. The previously approved berm was to achieve a peak elevation of 926. The previous approval allowed the applicant to take 3 years to construct the berm but unfortunately, due to issues regarding overhead power lines easements, the berm cannot be constructed as proposed and the applicant has abandoned that plan in favor of a new plan they believe achieves the same sound mitigation results. The original berm approved in 2010 will remain as approved and constructed, with the exception of the 130' gap under the transmission line easement area. The revised sound mitigation plan proposes the following additional 3 elements: 1. Construct a new sound barrier directly east of the electrical transmission tower to an elevation of 940 (14' higher than the existing sound berm, with a total height of 40'). The barrier will run north/south continuously a span of 345' -375' in length. This plan is illustrated on a Site Plan attached to the Wenck sound report. Conceptual cross - sections views of the proposed berm have been provided to staff. 2. Move the rubble dump area approximately 700' to the east (and 700' further away from the residential uses). This results in the processed or crushed material, to be swapped with the rubble pile location. 3. Limit the dump platform for gated trucks in the new rubble dump location to an elevation not to exceed 25'. The applicant intends to bi -sect the rubble dump area into two halves with non -gated trucks dumping on the north half at an elevation not to exceed 40' and the gated trucks dumping on the south half at an elevation not to exceed 25'. The northern 230' of the proposed sound berm/barrier would be constructed of compacted rubble. The remaining section of sound barrier, or the southern 130', would be constructed as partially compacted soil at the base (bottom 15' -19') and a manufactured concrete sound barrier (wall) for the top 18' -22'. This berm/barrier construction achieves several goals including: 1) adequately protects the transmission tower, 2) conserves yard space, and 3) allows protection of an existing drainage swales and run -off filtering system.
