2011/10/05 Council Agenda Packet

1 • CS Condition Assessment Technical Memorandum, 10 copies. • Agenda, workshop and meeting notes to review CS pipeline condition assessment. Task 400 — Street Assessment The purpose of this task is: to conduct cursory field reviews of specified City streets/alleys and intersections, utilizing and considering existing pavement condition surveys provided by the City; to summarize the general types of roadway distress currently exhibited along each street/alley segment and intersection; to evaluate adequacy of existing ADA improvements at intersections; to coordinate and determine the desirable pavement, curb and sidewalk improvements necessary to rehabilitate each street/alley segment and intersection; and to establish planning-level construction costs associated with rehabilitating each street/alley segment and intersection. These factors will then be considered in deciding where to ultimately locate combined utility and street improvements. Assumptions: • The Consultant will perform cursory field reviews and prepare preliminary construction cost estimates supporting rehabilitation or reconstruction for the following: o 18 north-south street blocks o 27 east-west street blocks o 21 north-south alley blocks • o 15 intersections. • The Consultant will utilize existing pavement condition surveys prepared by the City of Everett in summarizing existing street conditions, and to assist in determining desired improvements to each street/alley segment and intersection. • Distressed areas will not be measured in the field. • The City will perform pothole evaluation of pavement and base layers (up to approximately 2 feet deep)for selected intersections and pavement locations as agreed upon by the City and Consultant. Activities: • Review and graphically summarize existing pavement condition ratings provided by the City. • Perform cursory field review of designated streets, alleys and intersections; documenting general roadway/right-of-way conditions and taking photographs. The purpose of this task is to document both general and special conditions which may affect selected improvement measures and costs. • Assess the adequacy of existing curb ramps considering current ADA standards at designated intersection and/or roadway locations. • The Consultant will recommend pothole surveys of selected street and/or intersections, and will observe potholing by the City at mutually agreed upon locations. An allowance of 16 hours has been allocated for this purpose. • Coordinate and determine desirable method(s) of rehabilitation for each street/alley segment and intersection (based on visual inspections and pavement condition surveys), and prepare a preliminary estimate of probable construction cost associated with each street segment. • Prepare a Technical Summary Memorandum of preliminary findings, recommendations and estimated rehabilitation costs. • Prepare, conduct, and record minutes for a meeting to discuss street assessment findings.
