Monthly Enforcement Report A sediment removal issue is ongoing at the New Century site, Permit #99-05. One enforcement letter was sent by Tracey Galowitz on silt fence repair.. Four notices were issued to address the following violations: remove sediment from wetland (1), sweep streets (2), install rock construction entrance (2), remove sediment from silt fence (1), and repair gully (1). 5. PROJECT STATUS REPORTS Kohlman Basin Cliff Aichinger reported that the registered land survey has been. completed for the updated easement across the Country View- Golf Course property, and the Mogrens have agreed to sign the easement once prepared by Tracey Galowitz. Discussion moved to Earl Bancroft's October 26 memo, which is a report on the inspection of the timber weirs that were installed as part of last year's project work at Kohlman Basin. The west weir tends to hold back the water longer and at a higher elevation. Recommendations include adding more riprap filter areas along the easterly weir to help spread out the flow. The westerly weir also needs more riprap, but large clumps of vegetation must first be excavated. Brad felt that this type of maintenance will need to be done annually, and it has been added as Site 11 on the list of 2002 CIB Maintenance sites to be discussed later in the meeting. Battle Creek Channel Cleaning Staff have been investigating low flow problems,in the lower section of Battle Creek Park. Bob Johnson, various staff members, and Ramsey County Parks and Recreation staff have all visited the site, and the following issues were discussed: • The last channel cleaning by the District took place in 1992. Brad stated that the above-ground flow was increased at that time, which is adequate. • Brad submitted a cost estimate of $108,600 for sediment removal from 4800 feet of the channel. The work must be done in January or February of 2002 so that it doesn't disrupt the use of the park. This project has been also been added to the 2002 CIB Maintenance list as Site 12. • The scope of this maintenance project is beyond the capabilities of what Ramsey County crews can provide, due to the fact that too much time had passed since the last cleaning. • Access is difficult, which will require the use of smaller equipment. • Greg Mack stated that if the County were able to take on routine maintenance in the future, the source of the sediment must be found and efforts made to catch it further upstream where it can be easier to manage. • Larry Holmberg stated that there are a lot of upstream storm sewers that carry street sand into this narrow channel., which then fills up quickly. • A sinkhole has developed in the vicinity of a pipe repair job that was done in 1996. • Paul Ellefson felt that staff should develop an overall long term plan to, address future. creek issues. • The District may be able to assist the county with general aesthetic improvements for the park. Staff will work with Ramsey County Parks and Recreation staff to develop an annual maintenance program in order to keep the channel clear. Page 2 November 7, 2001 RWMWD Minutes
