6. 2. Public Works Committee Meeting Date: 09/17/2024 Primary Strategic Plan Initiative: Address infrastructure needs. Title: Consider Recommending City Council Order Request for Proposals for Sunwood Drive Concrete Pedestrian Crossing Replacement Topographic Survey Purpose/Background: Purpose: The purpose of this case is to consider recommending the City Council to request proposals for Sunwood Drive concrete pedestrian crossing replacement topographic survey. Additionally, for Staff to get feedback from the Public Works Committee on design options for the replacement concrete crossings. Background: The current 2024 through 2033 10-Year Capital Improvement Program (CIP) proposes concrete repairs for Sunwood Drive between Rhinestone Street and Zeolite Street, and for Rhinestone Street between Sunwood Drive and Ramsey Parkway in 2029. The concrete pavement along Sunwood Drive and Rhinestone Street were constructed in 2004 under Improvement Project 03-29. The project included colored concrete pedestrian crossings at 8 intersections (6 along Sunwood Drive and 2 along Rhinestone Street). Over the last several years, Public Works staff has addressed patching these concrete streets, typically using bituminous to fill voids in the concrete pavement. Additional curb replacement and small panel replacement work has also occurred. Though many repairs are required to the concrete pavement along this corridor, the most damage has occurred to the colored concrete in the pedestrian crosswalks. This is a significant safety concern because of the trip hazards created due to the deterioration of the colored concrete, along with increased pedestrian volumes anticipated due to continued development within The COR. The 2029 concrete repairs improvement project is proposed to address the pedestrian crossings and general crack repairs. Due to the creation of trip hazards in the pedestrian crossing areas, and the anticipated increase in foot traffic along Sunwood Drive due to the recent and proposed developments along Sunwood Drive, Staff has proposed splitting the Sunwood Drive and Rhinestone Street Concrete Repairs project in two. The proposed 2025 — 2034 CIP proposes to replace the colored concrete pedestrian ramps along Sunwood Drive in 2025. The remaining repairs are still proposed for 2029. Staff will use the survey data as design aids for the improvement project. Topographic surveys are essential to locate all existing site features and to create an existing ground surface, used as the base layer for designing the project. Staff has preliminarily inspected the existing pedestrian ramps adjacent to the crossings, and has noted several ramps do not meet current ADA standards. A summary of the findings is attached to this case. Committee input is desired on the following discussion topics and optoins. Discussion Topics: Options for replacing crosswalk concrete: 1. Stamped colored concrete 2. Stamped concrete with design and/or colored cure/stain
