• Stormwater. Stormwater generated from the site will be discharged via a storm sewer <br />system, under the exterior roadway to the north end of the SDA, then west under the City <br />Trail into a wetland upstream of the Rice Lake wetland complex. The discharge point will be <br />onto property owned by the ERL. Discharge from P-1 to the wetland west of the site has <br />been designed to minimize impacts by limiting bounce in the wetland, restricting flow rates, <br />and treating stormwater prior to discharge in accordance with applicable permits. The <br />stormwater management system will be regularly inspected and maintained to ensure it is <br />functioning properly. See also the statement regarding CUP finding number 4. <br />City Notifications and Access. ERL will notify the City at least two days in advance of liner <br />barrier layer installation or final cover barrier layer installation. ERL will assist the City in <br />arranging inspection of the site at any reasonable time the City requests. ERL will keep the <br />City informed of ongoing construction progress and shall specifically notify the City of <br />significant changes encountered in the geological, hydrological, or construction conditions. <br />The City may reasonably require work which is covered or otherwise obscured prior to City <br />inspection, to be re-excavated for City Inspection. <br />Construction Quality Assurance Reports. A Construction Quality Assurance (CQA) Report will <br />be submitted to the City prior to the placement of waste on newly constructed lined areas. <br />A CQA Report shall also be submitted for landfill areas which receive final cover. The report <br />shall demonstrate that the work is completed to the plan specifications. The Report shall be <br />certified by an engineer registered in the State of Minnesota and shall include but not be <br />limited to: <br />- All relevant construction specifications; <br />- All shop drawings for prefabricated components; <br />• = Photo documentation of all critical aspects of construction; <br />Deflection testing results for leachate collection and transmission pipes; <br />- Narrative description of all as-built variances from the plans and/or specifications; <br />- As-built cross-sections of the liner sub grade; <br />- As-built elevations for all pipe inlets and outlets and pump-on/pump-off controls; <br />- Completed manufacturer warranties; <br />- All physical testing results for soils and other materials used for construction. <br />Aesthetics. Visual impacts will be minimized through buffers, new berms, and trees. <br />The existing Conditional Use Permit requires a 200-foot buffer zone around the existing <br />landfill and the preservation of existing trees in the buffer zone. The proposed <br />Landscape/Screening plan for the SDA is presented in Section 1.2.4 and increases the buffer <br />zone in the SDA. The Landscape/Screening Plan is shown in the drawings labeled L2.01, <br />L2.02, and L5.01. Renderings of the Landscape/Screening plan are presented in Exhibit 3. <br />ERL intends to enhance the existing screening plans to effectively screen views of the landfill <br />from TH 169, 221St Avenue and the City's Railroad Hiking Trail. There is an existing wooded <br />area to the west of the SDA that would be maintained and which fully screens the SDA from <br />the trail corridor. Berms and trees would screen the SDA from 221St Avenue. The existing <br />berm along TH 169 would be enhanced with additional planting. Additional detail regarding <br />existing and proposed screening is provided below. <br />• <br />Elk River Landfill SDA W ~ Bonestroo .,~Wenel< Section 4-5 <br />Land Use Application ,~R„~~,~,~,~,« <br />
