The project limits are from South Shore Blvd. to Iron Mountain Blvd. The project goals are to improve stormwater conveyance and quality, pavement condition, and pedestrian facilities. The project team has completed the preliminary design phase including a robust public engagement effort. This report provides more detail on that process including results of the community outreach, the design work performed, and staff recommendations. BACKGROUND The FY 2021/22 to 2026/27 Capital Improvement Plan showed this project being funded in fiscal years 2023-24, 2024-25, and 2025-26. On January 7th, 2022, the City Council allocated $2.8M of American Rescue Plan Act (ARPA) funding to this project. The project is now shown in the current CIP (FY 2023/24 to 2028/29) for fiscal years 2023-24 and 2024-25. Lakeview Blvd is classified as a Neighborhood Collector within the City of Lake Oswego's 2014 Transportation System Plan. It carries approximately 3,000 average daily traffic (ADT), and is situated between residential homes and a railroad line that bisects the city. The majority of traffic is considered residential through traffic. The total length of this stretch of Lakeview Blvd is approximately 1.15 miles and starts where Lakeview Blvd meets South Shore Blvd and ends at the roundabout at the intersection with Iron Mountain Blvd. The current surface pavement condition is good as a 2-inch inlay was placed in 2019. However, the structure beneath the surface is poor and requires reconstruction. This was an intentional approach in anticipation of traffic diversion during the major Boones Ferry Road Project work, and to provide relief from the failing pavement while waiting for the full capital project that was anticipated about 5 years later. The southwestern portion of the project along Lakeview Blvd has an uneven shoulder walkway on the north side west of the Goodin Easement at 3050 Lakeview Blvd. There is very minimal to no shoulder space east of the Goodin Easement to the roundabout. Parking along Lakeview Blvd. can be challenging during the summer months when the Lake Grove Swim Park is open, and throughout the year when contractor traffic frequently blocks the shoulder. DISCUSSION Project Development Projects identified in the TSP are not typically detailed adequately to move straight into final design. Field survey, alternatives analysis, and public engagement are often necessary to determine what is the best approach for implementing any improvements. Therefore, the first Respect. Excellence.

Public Outreach Process Staff held a public outreach meeting on June 13th to gather input and concerns regarding the proposed project. Major themes of feedback received were safety in the curved section between Summit Drive and Iron Mountain Blvd, pedestrian facilities, stormwater conveyance, and parking. Balancing the need for improvements with constraints and funding, staff developed design alternatives which were presented at a second neighborhood meeting on September 19t". The audience was generally supportive of the design concepts, but there was disappointment that a sidewalk through the curved section was not proposed. Staff described the various options that were evaluated and all the reasons they were found to be infeasible. Several residents requested that Lakeview Blvd. be converted into a one-way road. The eliminated travel lane could possibly be repurposed to allow room for a bike lane and a sidewalk. This approach works well when there are convenient alternatives, such as in a grid roadway system. While this concept does help achieve one of the project goals, it comes with many concerns. Converting Lakeview Blvd. to a one-way street would add significant additional traffic to adjacent roads (such as Upper Drive, Bryant Road, Lake Grove Ave, and South Shore Blvd). Additionally, this conversion would add delay to nearby signalized intersections as well as add time for many local trips, including those from emergency response. Aside from the transportation impacts, there is also an associated environmental impact that needs to be considered. For these reasons, staff are not recommending converting Lakeview Blvd. to a one-way road. There was also community feedback suggesting other measures to complete the sidewalk from the Goodin Easement to the Iron Mountain roundabout. This included the use of retaining walls on the north/west side and/or a cantilevered sidewalk above the steep slope on the east side. There are several constraints in this area that make either of these approaches highly infeasible including an estimated cost exceeding the total project budget for just the sidewalk, significant relocation of overhead utilities, the required removal of several mature trees, and the steepening of private driveways, amongst others. For these reasons, staff is not recommending constructing a sidewalk through this area. Proposed Design for Lakeview Blvd Based on the community feedback and engineering analysis, staff developed a design concept that keeps all currently available parking spaces along Lakeview Blvd., constructs an ADA compliant sidewalk between South Shore Blvd and the Goodin Easements, introduces a crosswalk at the swim park, provides a complete stormwater management system, and reconstructs the roadway. While the ideal solution of a full sidewalk through the curved section was found to be infeasible, the design team is proposing some smaller scale solutions that can improve the Respect. Excellence.

FISCAL IMPACT The current CIP shows this project in the Street Fund for$1,000,000 in FY 2023-24 and for $5,500,000 in FY 2024-25. It is also shown in the Storm Fund for$500,000 in FY 2023-24 and $1,000,000 in FY 2024-25. The total project budget is $8,000,000. The preliminary cost estimates are consistent with the project budget and staff will continue to manage the project with the intent of delivering at or under budget.
