<br />. <br />e <br /> <br />~ <br /> <br />. <br />- <br /> <br />REPORT ON FEASIBILITY STUDY <br />FOR 163RD AVENUE N.W. AND OLIVINE STREET N.W. <br />STORM DRAIN IMPROVEMENTS <br /> <br />Scope: <br />The purpose of this study is to determine the feasibility of providing storm drain <br />improvements to serve the above referenced area. <br /> <br />The project area lies within the Northwes~ Quarter of Section 15 and the Northeast <br />Quarter of Section 16, Range 25 West, Township 32 North, City of Ramsey, Anoka <br /> <br />County, Minnesota. <br /> <br />The area of benefit is bounded by 163rd Avenue N.W. on the North, Olivine Street <br />N.W. on the West and Marble Street N.W. on the East as shown on Exhibit A. Project <br />construction is proposed to take place at the intersection of 163rd Avenue N.W. and <br />Olivine Street N.W. <br /> <br />Existing Conditions: <br />The existing drainage system in the area consists of ditches, culverts and ponding <br />areas. The specific area of concern addressed in this. report is located South of <br /> <br />163rd Avenue N.W., between Olivine Street N.W. and Marble Street N.W. This area <br />presently drains northwest towards the intersection of 163rd Avenue N.W. and Olivine <br />Street N.W. Since there is not a culvert at that intersection, flooding of parcel <br />1880 as shown on Exhibit A occurs during the spring thaw and during periods of heavy <br />rainfall. <br /> <br />Proposed Drainage Improvement: <br />To resolve the drainage problem, it is proposed to install a culvert across 163rd <br /> <br />Avenue N.W. and reconstruct the ditch along Olivine Street N.W. It is proposed to <br />raise the ditch grade south of 163rd Avenue N.W. and lower the ditch grade north of <br /> <br />-1- <br />
