Another question was raised regarding any dredging that will occur on the south side of County Road B2 on either side of "Lake George." Brad Lindeman stated that they are proposing improvements to culverts on this section of the roadway through the installation of flared -end sections. This will require removal of the existing sediment build -up. Another resident asked if concrete curb and gutter will be installed. The City Engineer stated that concrete curb and gutter will be installed in most areas. Terry Noonan indicated that the County would typically install bituminous curb and gutter as part of its project. Since the City will be taking over this roadway, they prefer the installation of concrete curb and gutter due to its more durable nature. The City is then responsible for the cost of this component as well as coordinating its construction. Brad Lindeman continued with the proposed drainage improvements: ♦ Brad reported there will be improvements to the drainage at Greenbrier Circle and County Road B2. He stated that approximately nine acres drains to that area where two catch basins currently exist. He stated that given the steep grade of that area, those catch basins cannot handle the volume of water flowing to that point. He also stated that an existing pipe from the south side of County Road B2 flows north and enters the current 12" pipe in this area. The overall system as built is too small to handle this much drainage. Brad feels the solution is to add three more catch basins in this area (Greenbrier Circle and B2) and a new storm sewer line on the north side of B2 from Greenbrier Circle to the existing metal pipe that discharges at the east property line of 711 County Road B2. These pipes will then empty into the ditch being re- established in this vicinity. ♦ 675 and 681 B2 will be flood - proofed for 100 year storm events. This will be done by installing small berms around the homes that will be blended into existing landscape at higher elevation points. A sump drainage system will also be installed to address water inside the bermed area. The City Engineer then talked about the City's policy of installing concrete curb and gutter when roads are improved given its long -term viability and improved protection for the road structure. He stated that along County Road B2, concrete curb and gutter will be installed everywhere that it is feasible except at the low point where the Watershed has designated water flow past the street into the revised drainage system. The curbing proposed would be Style B -4 -12. The City will also be installing concrete driveway aprons in the transition area. The City Engineer pointed out that survey work still needs to be done for these improvements to allow us to coordinate with Ramsey County's recycling project. He also pointed out that the City's policy is that 85% of the cost of curb and gutter is assessed. Typical assessments are on a front foot basis and are adjusted for equity purposes based on City policy. He reviewed development deferral options and assessment limitations of 125 lineal feet for non - subdividable property. He stated given the City's policy, assessments are expected to be in the range of $10 to $15 per assessable foot given the lack of assessable footage derived from this project. He stated that a public hearing will be held (likely in the first week of February) at which time residents can voice their concerns on the Pao �• 3
