10. I1. 12. 13. I4. on the residence. Some of the water could be directed from the ditch along the roadway which drains into this low area, by diverting it to a wetland east of Chameleon Street. Such a modification could be made along with the paving of Chameleon Street. However, the low area is also fed by drainage from the area east of Gibbon Street. Septic Field Flooding at 6508 171st Lane This lot has its septic field located in close proximity to the right-of-way of 171st Lane. The ditch along the roadway is shallow and relatively flat. During heavy rainfalls, run-off from a recently constructed drive, and a contributing drainage area to the south and west drains toward this roadside ditch. Ponding occurs in the ditch and adjacent low area which floods over the septic field and backs up into the resident's basement, which is lower than the elevation of the ponded ditch. Also, the residential property across the street has complained of fi'ont yard flooding which is due to the roadside ditch not being deep enough to drain his yard. Staff's position is that the ditch functions adequately to drain the street. Standing water in Roadside Ditch at 16800 St. Francis Boulevard The resident complains of water standing in the roadside ditch along the St. Francis Boulevard service road and along 168th Avenue. A culvert and deeper ditching would dry the ditch quicker~ Staff's position is that the ditch functions adequately to drain the street. Drainage onto the Property at 9158 Collins Drive The dirt street of Collins Drive is graded from east to west and runs off onto the property on which no drainage easement exists. There is no potential for damage to the structure and no evidence of water damage beyond a short term ponding on the lawn area. Staff's position is that drainage should be addressed along with the paving of the street. Flooding of the Intersection of 164th Lane and Azurite Street This intersection is a natural low point and no provisions had been made for drainage. The roadway becomes submerged in heavy rainfalls and after significant snow melt events. Also, water ponds in the yards adjacent to this intersection. No structures are in danger of flooding. Flooding at Noon's RV, Skelgas, and Anoka West Pet Hospital on Highway #10 These businesses flood frequently after heavy rainfall events. A storm water project has been proposed and will be addressed in the current storm water comprehensive plan. Section 22 Drainage / Maintenance of County Ditch 3 A low area east of Ramsey Boulevard between 156th Avenue and 153rd/t55th Avenue receives mn-off from City streets, but no drainage easement exists over these low areas. In addition, Wetland 656 (south of 153rd/155th Avenue east of Ramsey Boulevard) has no outlet and the water level in this wetland has been within one foot of the low point of the roadway. Minor improvements have been implemented to provide an outlet for drainage through this area. However, consideration of re-establishing a ditch connecting Wetland 656 to County Ditch 3 and reditching County Ditch 3 would provide added flood protection for the residences in Section 22, along Wetland 656, and along County Ditch 3. This issue is to be addressed in the current storm water comprehensive plan. Freezing of catch basin on 153rd/t55th Avenue In the spring of the year, the catch basin on I53rd/155th Avenue between C.S.A.H. #5 and County Road #56 have periodically frozen shut, causing road flooding from snow melt. Improved drainage from the adjacent wetlands by cleaning of the County ditches which drain them may reduce the potential for freezing. With the expansion of the amount of storm sewer pipe in the City's storm drainage system, an increase in the number of frozen storm drains should be expected. The public works department needs to acquire thawing equipment to address this growing need.
