1/2 M E M O R A N D U MM E M O R A N D U MM E M O R A N D U MM E M O R A N D U M TO: STREETS AND UTILITIES COMMITTEE MEMBERS FROM: NICK DEBAR | PUBLIC WORKS DIRECTOR DATE: NOVEMBER 21, 2011 RE: RECOMMEND DESIGN CONFIGURATION FOR SUNNYSIDE ROAD IN AREA E Program Background During the design phase for each individual street and utility improvement project, any non-standard street issues located within the project area need to be evaluated. Non-standard street issues include any of the following: 1. Streets with an existing street width less than 26 feet or greater than 32 feet; 2. Streets that are designated as and receive Municipal State Aid; and 3. Streets designated as pedestrian corridors as shown on the Trailway and Sidewalk Map located in the Comprehensive Plan (see attached). This above criteria stems from the adopted Street and Utility Improvement Program guidelines stating: “Typical streets will have a width of 28 feet measured from face of curb to face of curb. Streets currently between 26 and 32 feet wide will be reconstructed to the 28 foot standard. Other streets, including Municipal State Aid Streets and streets designated as pedestrian corridors, will have their reconstructed width evaluated on a street-by-street and project-by-project basis.” The Street and Utility Committee is charged with making a recommendation for these non-standard street issues. The recommendation is considered by the City Council, who has the final approval for all non-standard street issues. Current Conditions 1. 60 foot wide Right-of-Way 2. 30 foot wide bituminous pavement with integral edge curbing north of Woodcrest 3. 30 foot wide bituminous pavement with concrete curbing south of Woodcrest 4. 14± foot wide turf boulevards 5. mailboxes are located in east boulevard 6. 53 single-family homes adjacent to Right-of-Way - 28 on west side (6+22), 25 on east side (8+17) 7. no parking restrictions (does no comply with current State Aid Standards) 8. 305 ADT (Average Daily Traffic) south of Woodcrest (projected 458 ADT), 610 ADT north of Woodcrest (projected 915 ADT) Design Considerations If Sunnyside Road was not part of the Municipal State Aid System (MSAS), the roadway would be reconstructed to the standard street width of 28 feet. However, there is a separate set of stricter design standards that apply to MSAS streets. While a standard municipal roadway of 28 feet wide allows parking on either side of the street, a MSAS roadway does not allow any parking for the same 28 foot wide street. Most MSAS roadways have higher traffic volume than other local non-MSAS roadways. A street width of 32 feet is required for parking on one side of a MSAS roadway and 38 feet wide for parking on both sides (without Mn/DOT approved design variances). “No Parking” traffic signs are required to be installed for any traffic lane that does not have an adjacent parking lane. Therefore, the design options for street width comes down to a question of whether or not to allow on-street parking. Public Works Recommendation Given the residential character of Sunnyside Road, it is likely that on-street parking will be needed and desired by the adjacent residents. However, on-street parking on both sides of the street will add an additional 6 feet of pavement width to the existing street width, triggering more stormwater management requirements and additional construction costs. Therefore, allowing parking only on one side of the street is recommended by Public Works, requiring a 32 foot wide roadway - which also matches the ITEM NO. 7A
