2.6 Summary and Conclusions The streets within the proposed neighborhood improvement area have deteriorated to the point where reactionary maintenance is no longer effective. Given the amount of patching, cracking and utility repair areas, surface treatments such as seal coating or overlaying are not effective long -term, cost - effective solutions for maintaining these streets. Upgrades to the sanitary sewer and water main systems are necessary to maintain acceptable level of utility service and to protect the streets from future utility cuts due to spot repairs. Upgrades to the existing neighborhood drainage system are required to properly manage storm drainage from the roadway and to provide treatment prior to off -site discharge. To reduce long -term maintenance costs, reduce the intensity and duration of future pavement rehabilitation projects and increase the level of service of the infrastructure in the neighborhood, it is recommended that all streets undergo full reconstruction and utility upgrades. 3.0 PROPOSED IMPROVEMENTS 3.1 Living Streets — Street Widths, Sidewalks, and Geometrics The City of Maplewood adopted a Living Streets Policy in January of 2013. The high level goals of this policy include: • Encourage people to travel by walking or bicycling • Enhance the safety and security of streets • Maximize the infiltration of stormwater • Improve the quality of stormwater runoff • Enhance the urban forest • Reduce life cycle costs • Create livable neighborhoods Overall, the policy promotes narrower streets, additional sidewalks and bike lanes, boulevard rainwater gardens, and additional boulevard trees. Standard design templates were included as part of the policy. The original concept for the Arkwright- Sunrise project utilized the design template "Local Street — Option 1" as depicted in Exhibit 11 for all neighborhood streets. This design template utilizes a concrete sidewalk on one side of the street, with narrower streets and a depressed boulevard area. Staff was proposing a 24 -foot width for all neighborhood streets with this original concept as seen in Exhibit 4. As was noted in Section 1.3, there was little to no support for this original concept. Subsequently, staff revisited the Living Streets policy to find a common ground between the original concept and the feedback received from the residents. A revised design, as seen in Exhibit 5, was created utilizing the design template "Local Street — Option 3" from the Living Streets Policy for all streets except Arkwright Street, DeSoto Street, and McMenemy Street. This design template, as seen in Exhibit 12, utilizes a street section with no sidewalks, a depressed boulevard area for stormwater infiltration, and 28 -foot street widths. Arkwright Street, DeSoto Street, and McMenemy Street continued to utilize the original concepts features, including 24 -foot street widths, and a sidewalk on one side of the street. These three streets connect the interior 13 23
