PROPOSED STREET IMPRO%qDiEt,~ The present ~t~eets are ina~equate in oross-section for paving as a suburban street. Therefor'e,, major grading will be required prior to making any surface improw;manto It is proposed to ¢onstru~:t the streets in accordance with the City's Standard Suburban Street /;ection as shown on Exhibit B. This street section consists of a 29 foot wide bituminous surface with 4" bituminous berms on each ~ide to contain drainage. Drainage from this street would be directed to the proposed drainage easements on each end of Collins Drive as ~hown on Exhibit A. To keep the runoff from draining into the driveways on the south side of Collins Drive, it is proposed to lower the st~eet approximately one foot and provide a gutter to contain the wate~~ in the street. The thickness of materia~,s for the suburban street section would consist of 4 inches of g~avel base and 2" of bituminous. This section is equivalent to a 7~ton design in accordance to the Minnesota Department of TransportaaJ.on specifications. This section has been previously used in the city and other communities.
