As requested, this memo explains the $75,000 requested for Otsego Creep clean up and the issues
regarding the project.
Currently, the public works crews review the status of the creek for downed trees and during winters
with little snow cover and thick ice they clear those trees from the creek. Liftle to no excavation takes
place and no permit is required. Brad and his staff` secure right of trespass over sections of the creek
that are not covered by D&U, Obtaining permission from landowners has not been an issue in the
past nor is it anticipated in the future. The $75,000 was the cost estimated to clean excavate bottoln
and slopes) the section of creek north of 83dto Mason Avenue. The cost basis included DNR permits
to complete the pork as well as City crews' time and rental of needed equipment and is based upon
previous project costs from the section north of 901 Street completed a few years ago. The difference
between the too sections is the City has casement for the portion north of 90t" Street and does not for
the proposed section. This section is through farm fields and pasties. The stream has vertical galls
and a vee;fir narrow defined creek section. Wetlands are along much off'this section which complicates
the permitting process but with the track record we established with the t" St section, we envision
obtaining a permit will be much easier. Another issue is the creek was straightened through this
section at some point between 1963 and 1991, The DNR may want the creek's original route restored
and the property owner will likely not.
The need for the improvement is tip for discussion. Due to the narrowness of the creek, the creek
overflows its banks nearly every spring. This does little damage to the farmers' fiefs or pastures. It
aloes however impact 4 or 5 residents who use 87th Street to access their homes. "' Street is also
overtopped nearly every year for a short period of time a day or two) and is generally passable as it is
usually only a few inches veep. Other than improving the creek section and keeping the culverts open
this is unavoidable due to the elevation of the street and surrounding topography,
Our recommendation would be to leave the funding in the C1P for the 5th year of the C11 and let the
project be Omplaint driven or development driver.
