Agenda - Public Works Committee - 03/20/2012

Tonight we would like to focus on a couple of the projects that are located in neighborhoods that are proposed to receive street maintenance activities this summer. I would like to draw your attention to section 6 related to Sodium Street. The house at 16756 Sodium Street (Lot 5, Block 2, Klemish Addition) experiened water in the basement during the heavy rain. The existing ditch on the west side of Sodium has minimal grade and there is minimal grade between the house and the ditch. This may have allowed infiltration to raise the groundwater level in this area. The report recommend installing a culvert under Sodium Street, regrading the west ditch of Sodium Street, constructing a berm to keep water in the ditch, and replacing the existing driveway culvert. The ditch would be graded to drain south and a culvert would be installed along the south property line to drain the water to the west. Klemish Addition was platted with 10 foot drainage and utility easements along the front, sides and back lot lines. The estimated cost for these improvements is $12,225. Additional temporary and permanent easments may be required to complete the work. These will need to be negotiated with the owner. This neighborhood is included in the proposed 2012 seal coating program. The pipe could be installed in advance of the seal coating. Funding Source: In the fall of 2011, while staff was in the process of updating the City's Capital Improvement Program (CIP), we budgeted additional funds to stormwater improvement projects over the next two years in an effort to address some of these concerns. The Capital Improvement Program (CIP) lists a $75,000 annual expenditure for the next 5 years to address city wide drainage enhancements. Staff Recommendation: Staff recommends installing a culvert under Sodium Street, regrading the west ditch of Sodium Street, constructing a berm to keep the water in the ditch, and replacing the existing driveway culvert. The ditch would be graded to drain to the south and a culvert would be installed near the south property line to drain the water to the west. The estimated cost of these improvements is $12,225. Committee Action: Motion to recommend the City Council include the work at 16756 Sodium Street (Installing a culvert under Sodium Street, regrading the west ditch of Sodium Street, constructing a berm to keep the water in the ditch, and replacing the existing driveway culvert. The ditch would be graded to drain to the south and a culvert would be installed near the south property line to drain the water to the west.) in the proposed 2012 Sealcoating Program.
