The Glenarden neighborhood is a single-family residential neighborhood located south of County Road E, between Snelling Avenue North and T .H. 51. The total length of streets within the neighborhood is approximately 1.5 miles. Streets within the neighborhood are bituminous, varying [ron122' to 32' wide. Much of the neighborhood has bituminous curb; there is no concrete curb and gutter in the neighborhood. There is existing storm sewer in the neighborhood but with the deficiency of curb and gutter, there is a significant amount of overland sheet flow. Primary storm \vater run-off froln the neighborhood makes its way to Lake Johanna, located south\vest of the neighborhood. The neighborhood is also served with city sewer and water. Pavement condition indices (PCI) indicate that the streets within the neighborhood are in poor condition, which supports the City" s cun+ent plans for reconstruction. The existing stonn sewer system will be expanded to complement the new concrete curb and gutter. The City of Arden Hills is cOlnpleting an inflovv and infiltration study at this time. hnprovements to the sanitary sewer systelTI \vill be based 00 the findings of that study and watermain improveInents will also be made as deemed oecessalY by the City. The City of Arden Hills has completed preliIninary plans for the project. In addition, residents have had the opportunity to attend two neighborhood infonnational meetings regarding this project. Primary funding for the project will COIne from special asseSSlnents and City funds. The Glenarden neighborhood is in the Rice Creek Watershed District (RCWD). Preliminary conversations have been initiated with the watershed district. The project is a reconstruction; therefore it will be necessary to meet the infiltration requirements set forth in the RCWD rules. Coordinating the requirements of the RCWD with the needs of the City and the expectations of the neighborhood residents will be critical to the overall success of the project.
