Gappa Title Director of Public Services Administrator Reviewed: At’cnda Section: Public Services Director ’s Report7 Item Description: Birch Lane Drainage Neighborliood Informational Meeting The purpose of this informational meeting is discuss the proposed project options which have been developed by City stalf, obtain feedback from the residents regarding the various options, address questions and concerns regarding the project, and for the Council to provide direction regarding the option to be constructed. i'rujcct Biickgroiiiid Storm water currently flows down Birch Lane towards the Baldur Park Road intersection, where tlterc is a catch basin in the southeast corner of the intersection and an c.xisting 8” pipe along the eastern edge of Baldur Park Road that drains into an c.\isting 15" culvert under North Shore Drive which outlets to Crystal Bay. An improvement project is necessary to address storm water drainage problems, particularly for those properties on the south side of Birch Lane. Currently, .storm water on Btrch Lane flows to the south side of the street and into the yards of the adjacent properties, where it tends to pond because the land is very Hat. 'I he first solution discussed with neighborhood residents, early in the project, was to install curb and gutter along the south side of the street to prevent the water from Birch Lane from Bowing into the adjacent properties. This solution would require less street rc-gradmg. as the water already Bows to the south side of the street. The residents were concerned about the equity of this solution, since all of the water from Birch Liine would be draining along only the south side ol the road. CMty staff also had concerns about the capacity of the gutter on one side of the street to carry all of the water from the street, and the capacity of the pipe and catch basin at the corner of Birch Lane and Baldur Park Road, to carry all of the water from the street. A proposed variation of this first solution was to install an additional pipe between the houses on the south side of the street to drain the water towards North Shore Drive, as this would alleviate the concerns regarding the existing pipe and gutter capacity. The residents h.id concerns that this would drain additional water into their front yards. Page I of 4 1 \
