I. RELATED EXPERIENCE <br />BROWN'S PRESERVE WETLAND RESTORATION <br />ANOKA COUNTY, MINNESOTA <br />Background <br />Public drainage systems often impact <br />wetlands, even when well -managed, <br />and these impacts require mitigation <br />under both state and federal law. <br />The Rice Creek Watershed District <br />(RCWD) manages several public <br />drainage systems within the lands it <br />serves. As a result, the RCWD <br />developed an interest in an ambitious <br />and pro -active approach to creating <br />wetland credits for the future, <br />streamlining the management of the <br />public drainage systems while bringing <br />additional ecological benefits at the <br />same time. <br />The Project <br />Investigation <br />The RCWD began this process by <br />engaging Houston Engineering, Inc. <br />(HEI), who serves as District <br />Engineer. The RCWD and HEI agreed <br />that the proposed 110-acre wetland <br />restoration project would not only <br />provide wetland credits but also restore <br />and improve the native ecosystem. <br />HEI and our team launched an <br />extensive study of the project area, <br />studying current hydrologic conditions, <br />investigating past conditions, and <br />analyzing plant communities for <br />diversity. All the while, the team sought <br />to understand how the site interacted <br />with the surrounding landscape. The <br />team used drone flights to capture <br />images to determine where restoration <br />activities were needed most. <br />Restoring and Controlling Hydrology <br />The project prioritized the creation and <br />banking of wetland credits. With this in <br />mind, HEI designed the necessary <br />structures, including a weir, to restore <br />and control the site's hydrology. <br />Construction of these features was <br />completed in the fall of 2012 for which <br />HEI performed construction <br />management. <br />» Location <br />Anoka County.
