Construction Drawings Near Completion

Work on the development of the construction drawings is nearing completion. The consultant teams 85% review set of drawings was recently sent over to the U.S Army Corps of Engineers. Because Lake Nokomis is a contributing property to the Grand Rounds Historic District the project is required to go through a Section 106 permit process. The proposed project also has a direct effect on the character of the shoreline, creating a natural edge instead of a hard edge like with the old WPA retaining wall, even though this project is proposed for areas where the historic integrity of the wall never existed or was lost due to collapse. When the Corps of Engineers finishes their review they will send the plans on to the State Historic Preservation Office (SHPO). Given the nature of the project, it is our belief the proposed design will meet the Secretary of the Interiors Standards for Rehabilitation, and has no adverse effect on historic properties.

We expect the review by the U.S. Army Corps and SHPO to wrap up late this year. When that happens the design drawings will be completed. We expect to publicly bid this project in early 2019.

The proposed design uses three different planting zones along the shoreline. The emergent wetland zone starts at the ordinary high-water level (OHWL). This zone extends just into the lake, below the OHWL. Once established, the vegetation reduces the wave energy as it comes ashore. At the edges of the emergent zone in the lake will be a wave break/fish exclusion fence. This fence is temporary and allows the emergent planting to become established. Between the OHWL and the delineated wetland boundary is the shoreline buffer zone. The upland buffer zone starts at the delineated wetland boundary and extends 4 feet from the paved trail. This 4-foot strip will be mown grass. A different seed mix is used in each zone and is compatible with the environmental elements of the zone. An upland buffer fence encircles the new planting areas and connects to the wave break fence at the OHWL. Like the wave break fence, the upland buffer fence is temporary and will help the plants become established. A variety of access points will still remain so people can access the lake.
