October 20, 1997 To: Cn•ass Lake Management Organization Board h'rom: Karl P. Keel, Roseville Director of Public Works Re- STAFF REPORTS ON P1/Nll1NG MATTERS - ROSEVILLE The following is a summary ofprojects which have an impact on the Grass Lake Water Management Organization watershed: Owasso Hills Subdivision. This residential project has been ongoing for a number of years. Homes continue to be constructed. Generally, stormwater from this project is collected within existing wetlands. During larger rain events, stormwater is pumped from this subdivision to an existir~C wetland near the intersection of Western Avenue and South Owasso Boulevard. This wetland traditionally drained across South Owasso Boulevard to Ladyslipper Park and finally to Lake Owasso. In approximately 7 980, the culvert under South Owasso Boulevard was plugged rendering the wetland landlocked. This past summer, as a result of the large amount of rain and development of new townhomes immediately west of the wetland, minor flooding has occurred that has required the city to manually pump stormwater from the wetland to Ladyslipper Palk. Throughout the sum~•ner the city has attempted to acquire an easement across private property to restore the original drainage to the area. Unfortunately, easement negotiations were unsuccessful. To remedy this situation, the city is installing a new outlet to this wetland along the east side of South Owasso Boulevard that will connect the old culvert under the road to an existing stormsewer system further south. This existing system discharges to Ladyslipper Park. Therefore, the overall drainage pattern will remain the same. 2. Y.,akerid~e Nursing Home. In July I reported that the Lakeridge Nursing Home planned to eonstnict a new parking lot north of their facility that would have required a large amount of grading and the construction of a large retaining wall. In response to neighborhood and city concern, the nursing home has agreed to pursue other parking solutions rather than disturb the neighborhood. The home is currently working with Merideth Cable, the owners ofthe old Owasso School, to develop a joint parking plan. ZOiZO 'd 8 i :OZ z6~ OZ ~-~0 SlZZ-06G-Zt9~ xe~ ~~~I~3S02i .~0 J.lIO
