ATTACHMENT D Public Works Administration City of Eugene 858 Pearl Street M Eugene, Oregon 97401 EMORANDUM (541) 682-5241 (541) 682-6826 FAX www.eugene-or.gov Date: October 2, 2007 (revised) To: Mayor Piercy and City Councilors From: Kurt Corey, Public Works Director Subject: Transportation Facility Design Standards Design Standards and Guidelines for Eugene Streets, Sidewalks, Bikeways and Accessways The minimum street width allowed in the Design Standards and Guidelines for Eugene Streets, Sidewalks, Bikeways, and Accessways (Arterial and Collector Street Plan and Local Street Plan) is 20 feet (two ten-foot travel lanes). There is a set of criteria for exceptions to the minimum street width. The criteria for exceptions include: ? Topography or slope constraints; ? Significant trees or vegetation; ? Other natural resource constraints, including wetlands, wildlife habitat, etc.; ? Historic resources ? Insufficient right-of-way, and inability to obtain additional right-of-way at reasonable cost and within a reasonable time frame for the project; ? Adopted Council policies, including those found in neighborhood plans. ? For a city-initiated project, the Council decides not to approve a proposed project design that meets the standards of this chapter, but, after a design process that includes input from affected property owners and interested persons, the Council approves a design that the City Engineer determines is safe and functional. (This criterion was adopted administratively after the Council directed staff to substantially modify the design of the River Avenue improvement project. The project had been designed in accordance with the design standards included in the Arterial and Collector Street Plan, but was not acceptable to the majority of the property owners abutting River Avenue.) It is staff’s determination that none of the criteria for exceptions that would warrant a minimum street width of less than 20 feet are met for the streets included in the CSS process. This determination was made in part by the comprehensive topographic survey conducted as part of the CSS process. The topographic survey identified natural resources, trees, topographic constraints, public and private utilities, existing pavement, and public right of way. Page two of this memo compares pavements of 20 feet and 18 feet using the exception criteria. The Design Standards and Guidelines for Eugene Streets, Sidewalks, Bikeways, and Accessways were adopted by Council resolution with a provision that the Design Standards and Guidelines could be amended administratively.
