The Eugene Code allows the City to pay the design costs up from and then, if the improvements are built through a local improvement district to include those costs in the assessments to the benefiting properties. 3. What are the boundaries (minimum design standards) for the context sensitive design process? Exhibit A shows three design alternatives. Alternative 1 is the current minimum design for a neighborhood collector in the Arterial and Collector Street Plan. Alternative 2 is a modification of the current minimum design for a curb and gutter street. Alternative 3 is the minimum design for a curbless street design. The minimum designs shown in Alternatives 2 and 3 may require changes to the design standards in the Arterial and Collector Street Plan. The minimum standards would be the same for either a neighborhood collector or local street. The basis for the minimum standards for the individual components of a street are discussed below: a. Pavement Width - The minimum pavement width would be 20 feet based upon two 10-foot travel lanes. The minimum travel lane width of 10 feet is based upon the urban service providers dependent on the street system including emergency responders, public transit, and garbage and recycling services. Many of the vehicles providing these services measure 9-1/2 feet from mirror to mirror. b. Sidewalk - The minimum standard is a sidewalk on at least one side of every new or reconstructed street as required by the State Transportation Planning Rule. The sidewalk would be hard stable surface, physically separated from the travel lane. This is consistent with the standards of the Access Board, a federal agency with the authority and responsibility to develop accessibility standards under the American with Disabilities Act. The minimum unobstructed width of a sidewalk is five feet. This provides sufficient room for two pedestrian to walk side by side or to pass one another. This is one foot wider than the minimum of four feet established by the Access Board. c. Traffic Calming - Crest, Storey and Friendly are the primary routes for emergency responders. Therefore, the traffic calming options for the three streets include: Roundabouts Traffic Circles Raised Crosswalks Curb Extensions Parking Bays Chicanes Raised Medians Pavement Surface Angled Slow Point Modification with Median Landscaped Midblock Neckdown Speed Tables Roadway d. Curbless Street - Although fairly simple in design, a curb provides multiple functions for a street including conveyance of drainage, stability to the edge of pavement, physical barrier separating the street from sidewalk and a vertical surface necessary for a street sweeper to be effective. In developing a curbless design, these multiple functions are addressed by numerous design elements including a drainage swale with L:\CMO\2005 Council Agendas\M050629\S050629B-attB.doc
