Obvious the type and magnitude of the architectural and aesthetic design will impact the cost of these structures and ultimately the amount of the cost sharing by each community. MNDOT's cost participation policy states that the maximum aesthetic cost participation along the entire I -694 corridor is a percentage of the estimated project construction costs and is summarized as follows: Bridges: 7% of the bridge costs not to exceed $300,000 per bridge. (The cost of a basic bridge with basic aesthetics, then use 7% additional for corridor - enhanced aesthetics). Retaining Walls: 5% of retaining wall costs Noise walls: 4% of noise wall costs Other: 3 %, 2 %, or 0% of remaining project costs depending on the project type category. (Unweave the Weave would be at 3 %). The goal of the committee is to select an architectural and aesthetic design that can be constructed entirely within MNDOT's participation percentages. Summary of committee conclusions /decisions: • The committee identified the major corridor character to be predominately of an open /green/natural quality. The corridor traverses rolling hills and passes numerous lakes and wetlands. The area to the west through Fridley and New Brighton is currently more fully developed than much of the remaining corridor. • The committee supported the use of high quality, durable materials that would require minimal maintenance. • The committee supported a somewhat increased design emphasis on bridges at interchanges to denote nodes of business and commercial land uses that differ from more natural areas existing between bridges. The three concepts of the major corridor components (bridges, retaining walls and noise walls) were reviewed and discussed with the goal of selecting one as the preferred design for further development. I will present these three concepts to you at the Council meeting. Concept A was selected because of its: Strong emphasis on expressing the horizontal An appearance of the bridge structure being grounded, resting on a solid foundation Limited ornamentation Expression of random patterns Detailed and rustication which suggest natural form and character Community recognition can be easily incorporated. At the next committee meeting (January 29, 2002) we will be discussing material types and finishes, railing systems, lighting, landscaping, grading, signing, traffic barriers, fencing and community identity opportunities. The council needs to provide direction on: 1) Do you concur with the selected concept A? 2) If and what civic elements (community identity opportunities) they may which incorporated in the bridges, retaining walls, and noise walls that are to be constructed within our city limits.
