I WATKBRHFD MANAGEMENT PLANMIMG: CHAETEB__^5 During 1909, the District's proposed Chapter 509 Surface Water Management Plan was before Hennepin County for review, along with a proposed agreement concerning financing of the Capital Improvement Program. The District forwarded the Chapter 509 Plan to the Metropolitan Council for its review in March 1990 ftFVTSTON OF THE DISTRICT*S RULES In April 1989, the District adopted revisions to Rule E concerning dredging, and adopted Rule K providing for licensing of dredging contractors. These revisions were adopted following extensive meetings by the Board's Rules Committee, input from District staff and members of the public, and a public hearing on April 20, 1989. The changes to Rule E arose from the District’s experience with compliance problems and the need for more specific criteria concerning hydraulic dredging. Specifically, the revisions address hydraulic dredging standards, requirements for submission of soil boring logs, protection against seepage and subsurface drainage, the steepness of slopes in dredging projects necessary to avoid frequent re-dredging, and the use of silt curtains. Rule K requires the licensing of dredging contractors who perform projects in larger "priority" lakes within the District. The District had been concerned with unuermitted and unfeasible dredging projects performed in the past, and determined that the licensing of contractors is a reasonable and necessary means to ensure that projects are performed by qualified, dredging contractors in compliance with District rules. Rule K was also intended to protect consumers from enaaging dredging contractors who do not have the necessary and proper equipment to perform the project. OTHER DISTRICT PROJECTS AND COWCERMS At the request of the City of Shorewood and the Village of Tonka Bay, the District studied the feasibility of various alternative remedies to a persistent drainage problem at the intersection of Glen Road and County Road 19. The District Engineer continued with additional hydrologic analysis in 1989, recommending a number of drainage improvements in this subwatershed area to be submitted for review by the City of Shorewood. Manager Spensley met extensively in 1989 with officials from the City of Minneapolis to review plans for storm sewer and paving projects near the intersection of 42nd Street and Bloomington Avenue, and Sibley Park. The District entered into a contract with the City in 1989 to perform a hydrologic analysis for this project, known as the HEC II study, which was completed in May 1990. - 4 -
