<br /> " ,-,. '. <br /> . <br /> . <br /> Arden Hills City Council <br /> June 6, 1979 <br /> Page 2 <br /> not provide sufficient capacity for runoff from a storm exceed- <br /> ing a 5 year average frequency. <br /> A more conservative solution to the drainage problem is to <br /> install additional storm sewer capacity from the low point <br /> in Glenview Avenue to Valentine Park. This system would consist <br /> of two high capacity catch basins located in the low point <br /> on Glenview Avenue plus additional storm sewer with capacity <br /> to convey drainage from a 100 year average frequency storm. <br /> Even with additional capacity through an enlarged system as <br /> described, absolute protection would not be provided against <br /> flooding of the Can iff property if a storm greater than 100 <br /> year average frequency were to occur. <br /> Since the low point on Glenview Avenue is drained by storm <br /> sewer with limited capacity and excess drainage flows across . <br /> the Caniff property, we recommend additional protection be <br /> provided through an enlarged storm sewer system as described <br /> above. The estimated cost of the recommended system is $10,000. <br /> We will be available to answer any further questions the Council <br /> may have regarding this matter. <br /> . <br />
