continue north to Hillview Road along Eastwood Road. Phase I would
also include construction of a small detention basin south of Hillview
Road at Greenfield Avenue, with its outlet to be a 24 inch pipe
installed on Oakwood Drive to flow eastward to the Rice Creek outlet at
Quincy Street. Lateral storm sewers from County Road I and Jackson
Drive would connect to this.
Phase II would provide storm sewer laterals to connect the area generally
north of Hillview Road and west of Long Lake Road to the Spring Creek
trunk system built in Phase I. It would also include a 60 inch trunk
system running from east of the Launching Pad Supper Club south across
Highway 10 and County Road H to Rice Creek. To this system would be
connected lateral lines draining the area generally north of existing
Highway 10, south of County Road I, and west of Quincy Street. Phase II
would also include lateral improvements to drain the area generally
north of Hillview Road and east of Long Lake Road to the Rice Creek
outlet at Quincy Street.
Phase III would provide lateral extensions in several areas of the city
to connect them with the three trunk systems established in Phases I
and II.
Mr. Short presented a slide presentation, showing how the proposed
system would go through the City and the phases of the project.
Mr. Sunde gave a geological background of Mounds View. He stated that
between April 1975 and July 1975, the water level rose approximately
52 feet, and that in checking into other data available for the area,
he found that the water levels that were experienced in 1975 were
also experienced at other times, and had determined that rather than
the 1975 instances being an extremely rare case, they were more the
norm. He stated that the problem seemed more severe, however, because
of the increase in housing.
Mr. Sunde also stated that the proposed storm sewer system would not be
a cure -all but would certainly help alleviate much of the problem.
Mr. Short presented a graph prepared by Eigineer Hubbard, showing the
required capacity of the system versus the present capacity.
Seegar Swanson, of Swanson, Ehlers and Associates stated that the project
would be constructed in three phases and financed in three phases. He
also stated that the cost estimates have taken inflation into account,
and that all cost estimates were`madh.,onthe high side.
Mr. Swanson reported that the City had applied for Federal Assistance
but was rejected by the Department of Housing and Urban Development
but that outside assistance might still come through.
Mr. Swanson stated that the Council has taken into consideration the fact
that the northwest corner of Mounds View was recently assessed for storm
sewer laterals under Project 1973 -4, and that property owners in that
area would not be specially assessed for the new project. Other areas in
the City would be assessed at a rate equivalent to that paid by the
property owners included in Project 1973 -4, and that these special
