PROJECT NARRATIVE' <br />1. Project Description: Describe the scope of work. Indicate the major work Involved, Including a brief <br />comparison of existing and proposed conditions. <br />The City of Cle Elum is proposing a design and construction project for improvements to the <br />intersection of First Street and Billings Avenue, as well as stonnwater improvements along First <br />Street. Three infrastructure systems are being designed and constructed concurrently: Stormwater, <br />sidewalk, and roadway. <br />City leaders, staff, businesses, and residents defined a vision for spurring economic development in <br />the recent Downtown R,evitalization Plan, see attached "Downtown Revitalization Planning 1111: Street <br />Concept". To implement the Plan, the corridor project was separated into three succinct phases: <br />1) Phase One -Peoh Avenue and SR 903 (First Street) Intersection Improvements; <br />2) Phase Two -First Street Storm.water Improvements; and <br />3) Phase Three -Downtown Revitalization including First Street pedestrian and s1reet <br />improvements. <br />Phase One design is complete, and construction is scheduled to be complete by October 2018. <br />The First Street Stormwater and Billings Avenue Intersection Improvements is a meld between Phases <br />Two and Three, including completion of the stonnwater improvements, and design and <br />reconstruction of the First Street and Billings Avenue intenection. This intersection is the furthest <br />west on the First Street corridor as defined in the Downtown Revitalization Plan, serving as the <br />westerly '"book end" in defining the City's expected pedestrian commerce area and future walkable <br />"Main Street''. The concepts and amenities incorporated into the Phase One project were a direct <br />result of Cle Elum' s recent and unprecedented outreach during development of the Downtown <br />Revitalization Plan. These same concepts will be incorporated into the First Street and Billings <br />Avenue inter8ection improvements, for consistency throughout the downtown revitalization. <br />The City has prepared the following summary comparing existing conditions (before the project) with <br />proposed conditions (following project completion). <br />Existing Conditions . <br />Stormwater <br />• Currently, stonnwater runoff within the downtown basin is primarily unmanaged as the <br />infrastructure does not contain suitable features to collect and properly dispose of surface nm.off. <br />The few existing storm facilities along the corridor include a mix of mfiltrati.on trenches and a 24" <br />pipeline that drains to an open wasteway. The 24" storm drain pipe contains very few runoff <br />collection points, while a majority of the catch basins utilize an uncharacteristically small 6''x6" <br />grate, adding to the ineffectiveness of the existing system. Due to the very limited surface area, <br />these small grates clog easily and often, resulting in ponding and wintertime icing. Though public <br />works crews schedule ongoing system maintenance, these small grates become clogged and <br />unusable hours after rain and snow events. <br />• The First Street and Billings A venue intersection has four catch basins, however, they are not <br />located at the true low points, and one is not aligned with the curb. The curb and gutter at the <br />Billings Avenue intersection does not wmp the radius, causing ponding and settling of the <br />roadway in the immediate vicinity. <br />Sidewalk <br />• Sidewalk is deteriorating on both sides of First Street Each comer of the Billings Avenue <br />intersection includes a single, centered pedestrian ramp, not ADA conforming, and not aligned <br />4
