),, AVAILABLE ALTERNATIVES THAT WERE CONSIDERED MINIMIZE OR MITIGATE ENVIRONMENTAL .D EFFECTS TO WETLANDS ISCUSS WHETHER ANY REQUIRED COMPENSATORY WETLAND MITIGATION , FOR UNAVOIDABLE WETLAND IMPACTS WILL OCCUR IN THE SAME MINOR OR . AND IDENTIFY THOSE PROBABLE LOCATIONS Impacts: Given the scattered location of the site wetlands and the absenc the specific extent of wetland impacts cannot be estimated. Therefor evaluation it was assumed that all 14.4 acres of wetland identif waters of the US and under US Army Corps of Engineers (USACE) ju jurisdiction of the Rice Creek Watershed District as the local g Conservation Act. It was assumed for this analysis that all wetl development. However, some wetland may be preserved within the Mitigation Requirements: Based on compatible needs (wetlands neea water source, stormwater management needs a receiving area), the stormwater management areas and wetland replacement would be combined to the extent possible under curre number of constraints (topography, site grading) and challenges need to be addressed in order for these functions to work on-site and work together. The County and City are currently in the planning stage to design the regio plan. The USACE and Wetland Conservation Act (WCA) mitigation requirem USACE oversees Section 404 of the Clean Water Act and Rice Creek implements the WCA or MN Rule 8420. Wetland impacts are assumed to be replaced at a 2:1 ratio, meani impacted by the project, 2 acres will either be created or wetla state wetland bank. Given the site constraints, it is anticipatof wetland impacts would be replaced on site with the other half beoff-site by purchasing credits from the state wetland bank. The current WCA requiremen replacement is any new wetland created onsite would receive 75% reach 14.4 acres of onsite replacement, 19.2 acres of wetland wo buffers. This amount could be decreased if not all the wetland is impacte jurisdictional, or if RCWD allows more replacement within the ad other off-site locations. The purchase of off-site wetland credits would include 14.4 acres. The wetland bank sites where these credits will be withdrawn from would be required to be loc Area (BSA 7) and major watershed 20 (Mississippi River (Metro)). b) O-D THER SURFACE WATERS ESCRIBE ANY ANTICIPATED PHYSICAL EFFECTS OR ALTERATIONS TO (,,,, SURFACE WATER FEATURES LAKES STREAMS PONDS INTERMITTENT CHANNELS /),,,, COUNTYJUDICIAL DITCHES SUCH AS DRAINING FILLING PERMANENT INUNDATION DREDGING ,,,.
