Background-and Purpose
The existing Lake Mendota shoreline from North Park Street to North Lake Street was originally constructed in 1969 as part of a redevelopment of the lakefront after the original crew team boathouse was removed in 1968. This shoreline sidewalk currently provides an important general public access and pedestrian/bicycle connection function from North Lake Street west to the Howard Temin Lakeshore Path, west of the Memorial Union and the Limnology building. It is an integral part of the public lakeshore path system that runs from North Lake Street all the way to Picnic Point and on to Oxford Road on the far western edge of the campus, over 2 miles in length. As the eastern doorway to the Lakeshore Nature Preserve and the many academic facilities along the path, this public sidewalk must be maintained and repaired to maintain public safety. The five courses of limestone blocks stepping down to the water’s edge was designed by Peter K. Walker while an associate in the Office of Dan Kiley, each a nationally acclaimed landscape architect in their own right. The Kiley plan also included the 10 foot-wide exposed aggregate sidewalk immediately adjacent to the shoreline steps and a large breakwater near where the prior boathouse pier was located. Unfortunately, the limestone steps have seen significant problems over the years, especially after major storm events and ice movement in winter and spring. Several stones have slumped to the point of falling into the lake. The university and State of Wisconsin have provided emergency repair funds over the years (starting as early as 1979) to mud jack the stones back into place and at one point, removed the stones and backfilled with concrete to stabilize the sidewalk where the base materials was totally washed away. Most recently, in 2008, the area just north of the Below Alumni Center was repaired and filled to help stabilize the shoreline sidewalk to fix an immediate danger of fall stones and paving. These degraded conditions continue to create swimmer, pedestrian and bicycle user safety issues along the full length of the 800 lineal-foot shoreline sidewalk as the large limestone blocks and their backfill is washed away by the wave and ice actions. Cracks and uneven sections of the adjacent exposed aggregate paving have also been repaired several times over the years but continue to occur on a regular basis. The breakwater design also creates significant health and safety concerns as water, algae, trash and weeds are trapped behind the breakwater to the east but the prevailing northwest winds. The water stagnates and promotes weed growth in the shallow lake waters near this heavily used public area. This problem has occurred since The suggested removal of the breakwater, and its associated bollards, will help with water flow more easily along the lakeshore and reduce overall weed growth. The breakwater does provide one important function in that it is used twice a year by the university’s Hoofer sailing club to launch and remove sailboats that are moored in the area. This deepwater function (minimum

6 feet clear depth of water) will need to be replaced with the project or the function will have to be accommodated elsewhere on the lake. On the west side of the breakwater, in the rounded out corner, hundreds of loads of sand were originally installed in 1969 to provide a sandy bottom for the university’s swimming pier located just to the west. The swimming pier function must be maintained generally in this area and consideration for maintaining this sandy bottom swimming area must be taken into consideration when designing the new shoreline. Northwest of the Below Alumni Center and north of the Red Gym is the existing Class of 1917 plaza & flag stanchion, originally dedicated in 1970, which will need to be redesigned and reconstructed. At minimum, the plaque will need to be replaced to commemorate the original class gift. Replacing the flag stanchion is up for discussion. Project Scope and Description This project consists of rehabilitating approximately 800 lineal feet of failing Lake Mendota Shoreline adjacent to the lakeshore path between North Lake Street and North Park Street.
This project will remove and reinstall the existing limestone blocks in a re-aligned shoreline while using two different shoreline details of reinforced concrete sea wall and step foundations. The existing breakwater will be removed and the existing small bay north of the Red Gym will be filled in to create a much smoother shoreline alignment. All decorative exposed aggregate concrete along the adjacent sidewalk will be removed and replaced with this project. New site lighting is included for the area between the west edge of the Red Gym and eastward to North Lake Street. Lighting will match the current campus standards and be full sharp cut-off fixtures to meet dark sky compliance. There is also storm sewer facility removal and replacement as part of this project. The project also includes pre-planning and conceptual design services for the area between the Red Gym and the Memorial Union currently occupied by UW Parking Lot #1. This space will be designed to accommodate a future Alumni Plaza from Langdon Street north to the shore of Lake Mendota and carrying around to the Below Alumni Center. Functions of this area include alumni recognition spaces, landscape plantings, seating and gathering areas and iconic university images to portray the importance of university faculty, staff and alumni accomplishments. Consideration for a potential seasonal boat dock/pier/marina should also be part of the plans to be located north of the Below Alumni Center. The consultants will be expected to deliver an initial budget, conceptual site plans, drawings, and renderings to describe the Alumni Plaza for fundraising activities by the Wisconsin Alumni Association. Pre-planning of this area now assures that consideration is made in the waterfront redesign to facilitate the development of the Alumni Plaza in the future.

The 2005 Campus Master Plan shows this entire area redeveloped including additional green space and plaza development between the Red Gym and the Memorial Union. Work on the historic restoration of the Memorial Union building proper is a future project that is expected to be in design during the next year. The AE team will need to coordinate their design effort with that project when necessary. Scope of Services The selected consultant will provide pre-planning, design and budget estimates for 35% of the project completion. The A/E fee is based upon 35% of the projected total budget. That amount of $151,000 has been confirmed and authorized with the appropriate funding letter. The remaining project budget funding split is yet to be determined. The AE team will be responsible for researching, investigating and assisting the campus in applying for any Wisconsin Department of Natural Resources, Army Corps of Engineers, Chapter 30 permits and/or other shoreline construction permits necessary to accomplish the work The project consultants will be responsible for coordinating and providing any drawings, renderings or exhibits to describe the proposed project in at least one public information meeting and for the public EIA document. A separate consultant will be hired by DOA to develop a Type II Environmental Impact Assessment (EIA) to review and define any environmental impacts associated with the project. Well qualified consultant teams will include a collaborative effort between civil engineers and landscape architects that have direct project expertise in shoreline and waterfront restoration work of similar project size or greater. Consultants should have experience with shoreline construction permitting in the State of Wisconsin and assisting in gaining the necessary approvals from the various permitting and approval agencies. They should also have experience in public open space design as well as the design of seasonal boat marinas including the necessary permitting of the latter, if necessary.
