SUSTAINABILITY
Sustainability Plan Multi-Modal Accommodate future Towpath Trail in West Slope Multi-use path along proposed East Ninth Street and Ontario Street Addition of bicycle lanes on Abbey Avenue from W. 13 th St. to west end of Abbey Ave. Bridge 3 GCRTA Park and Ride Lot expansions Freeway Management System
Sustainability Plan Stormwater Reduced runoff to combined sewer systems. Stormwater management practices in full compliance with ODOT and Ohio EPA. DBT to construct detention-based BMP s Permeable pavement on Fairfield Ave tree lawn.
Sustainability Plan Cuyahoga River Incorporation of green bulkheads design (i.e., habitat pockets) along the Cuyahoga River for improved fish habitat Use of "ring chamber" pipes to aerate water headed to the river
Sustainability Plan - Materials Reuse of Medina block pavers on Central Viaduct Way Salvage Old Central Viaduct pier masonry for future Towpath Trail enhancements
Sustainability Plan Structures Durability Minimize bridge expansion joints Sealing concrete surfaces Emphasis in integrated design of structure drainage for minimal maintenance and long-term durability.
Sustainability Plan Energy Conservation Sustainable approach to be taken for bridge lighting, including prominent incorporation of LEDs Elimination of external lighting on overhead highway signs. Use of LED signal heads
Sustainability Plan Urban Landscape Median and tree lawn landscaping Green walls on Fairfield Avenue Green screen on retaining walls by Tri-C, Hilton Meadow grasses in west slope excavation area replace existing impervious surfaces Use of native landscaping materials
Sustainability Plan Design Build Team Requirements Demonstrate Responsible Approach to: Minimizing Energy Usage Maximizing Long-Term Durability on Structures Construction Materials and Debris Earthwork Erosion and Sedimentation Control
How will the aesthetic recommendations be incorporated into the design / build process?
Superstructure Shape and Appearance Proposed Specification: Main Span Portion of the I-90 Viaduct Shall Consist of Haunched Girders Reflects Design Principle: New bridge should be consistent with shape of existing bridges yet not imitative.
Form, Rhythm and Continuity Proposed Specifications: Abrupt girder depth changes only at end piers of main viaduct. Consistent material type (steel or concrete) and superstructure shape (I-girder or box) for entire length of bridge. Reflects Design Principle: Design should be consistent and coherent across entire valley, and speak with single design vocabulary
Architectural Lighting Proposed Specifications: An architectural lighting scheme will be designed for the new viaduct bridge. Plan shall be comparable to the lighting of the other downtown Cleveland bridges. Sustainable lighting plan requirements include LED fixtures Reflects Design Principle: Design should incorporate opportunities for aesthetic lighting in keeping with the lighting schemes common to existing bridges in the valley
Attention to Detailed Aesthetics Proposed Specifications: No stiffeners on the outside of the fascia girders. No horizontal drainage pipes below the bottom plane of the superstructure. Drainage systems required to match color of adjacent concrete/steel bridge elements. Reflects Design Principle: Treat side, under and above deck views with comparable effort to global views
Pier Configurations Proposed Specification: Single box superstructures single stem columns Twin box superstructures twin columns in line with box girders Multiple girder superstructures no more than two columns Reflects Design Principles:..placement of bridge supports should be conducive to positive and beneficial future land use adjacent to underside Consideration of people environment adjacent to and under bridge is important
Pier Shape Proposed Specification Rectilinear cross-section, reflective of adjacent high level bridges, with vertical articulation. Curved transition between top of pier caps and base of columns Reflects Design Principle: New bridge should be consistent with shape of existing bridges yet not imitative.
Streetscapes and Landscapes Proposed Specifications: In this case, the Request for Proposal (instructions to bidders) will include prescriptive drawings requiring design elements being discussed for Gateway and Tremont areas Reflects Design Principle: The design should be sensitive to the scale and appearance of the neighborhoods where it touches down and should respect the special character of Tremont and Gateway
Post-Award Public Involvement Design Build Team will prepare concepts for consideration at two stakeholder meetings and one public meeting. Stakeholder Meeting 1 Public Meeting Stakeholder Meeting 2 City Design Review and Planning Commission Final Approval
