f which drains into this low area, by diverting it to a wetland east of Chameleon Street. Such a modificatioh could be made along with the paving of Chameleon Street. However, the low area is a4o fed by drainage from the area east of Gibbon Street. 8. Septic Field flooding at 6508 171st Lane This lot has #s septic field located in close proximity to the right -of -way of 171st Lane. The ditch alo g the roadway is shallow and relatively flat. During heavy rainfalls, run -off from a recen y 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 t 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 o front yard flooding which is due to the roadside ditch not being deep enough to drain his y _ d. Staff s position is that the ditch functions adequately to drain the street. 9. Standing watr in Roadside Ditch at 16800 St. Francis Boulevard The residenu complains of water standing in the roadside ditch along the St. Francis Boulevard sei►vice road and along 168th Avenue. A culvert and deeper ditching would dry the ditch quicker. Staffs position is that the ditch functions adequately to drain the street. 10. Drainage ontd the Property at 9158 Collins Drive The dirt streei 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 evidebce of water damage beyond a short term ponding on the lawn area. Staffs position is th4t drainage should be addressed along with the paving of the street. 11. Flooding of tide Intersection of 164th Lane and Azurite Street This intersec on is a natural low point and no provisions had been made for drainage. The roadway bec mes 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. 12. Flooding at loon's RV, Skelgas, and Anoka West Pet Hospital on Highway #10 These businses flood frequently after heavy rainfall events. A storm water project has been proposi and will be addressed in the current storm water comprehensive plan. 13. Section 22 Drainage / Maintenance of County Ditch 3 A low area t of Ramsey Boulevard between 156th Avenue and 153rd/155th Avenue receives run-off from City streets, but no drainage easement exists over these low areas. In addition, We land 656 (south of 153rd/155th Avenue east of Ramsey Boulevard) has no outlet and tht, 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 irea. However, consideration of re- establishing a ditch connecting Wetland 656 to Count► 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 addre�sed in the current storm water comprehensive plan. 14. Freezing of catch basin on 153rd/155th Avenue In the spring of the year, the catch basin on 153rd/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 1 iipe 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. /ccr 0
