12. Location: Open drainage channel from Bonnieview St. to Honeywood Ave. Nature of Problem: Steep sided open drainage carrying public runoff from piped system at Bonnieview (N5E1 -5919) crosses private property. City has no legal authority for access to this drainage way. Access for all previous maintenance has been granted through verbal permission of the property owner. If such permission is withdrawn, City will not be able to perform routine and /or emergency flood contx4 Recommended Solution: Acquire easement along channel for access of mecha- nized maintenance equipment. Status: 13. Location: Street surface at intersection of 22nd Ave. and McMillan St. Nature of Problem: Flow of water up from cracks and seams in the concrete pavement at the center of the intersection. Water sheets down the fairly steep grade of 22nd Ave. creating an algae- covered street surface and a potential ice hazard in Winter. Maintenance has not been able to determine if the water is of natural or EWEB origin. The water has tested positive for trace chlorine by the City, but EWEB is reluctant to acknowledge a possible leak. There are no stormwater structures in the immediate area other than curb and gutter. Recommended Solution: Have Engineering design a local system to intercept and convey the water if it is groundwater. One suggestion was for EWEB and the City to approach the project as a joint venture on the chance an existing waterline leak were found during the construction phase. Status: 14. Location: Ditch between Long Island Drive and Norkenzie Minda PUD Nature of Problem: Street flooding on Larkspur Loop due to the piped stormwater system backing up. This system outfalls to this ditch, which is in need of cleaning and vegetation removal. Two large concrete culverts pass under Long Island Drive near this outfall. They were found to be half full of sediment and debris and have been recently cleaned. It has been determined that the City has little or no ease- ment to several hundred feet of the ditch, which continues from the culverts and runs through the back yards of several residential lots. Recommended Solution: An easement must be obtained for maintenance or construction purposes. The ditch requires extensive rehabilitation through vegeta- tion and debris removal. Another solution is that engineering consider a design to enclose the ditch up to the point where it enters the piped system under the PUD. Status: 15. Location: Fir Crest (near Hendricks Park) Nature of Problem: Heavy runoff from bubbler catchbasin being directed away from gutter on West side of street and entering driveways on the East side, creating drainage problems for residents. aplistupd 7/95 bne 6
