Curb stop repairs were located on house side at 2008 Jerrold (2019) <br />and 2022 Edgewater (2020). <br /> <br /> <br />2.5 Drainage <br />The existing drainage pattern within Area 1 Hazelnut Park Neighborhood is generally from <br />east to west. Streets and private property drainage is conveyed overland or through storm <br />sewers, discharging into the existing water body west of the Elmer Anderson Trail near <br />Cleveland Avenue, within the Jones subwatershed area. This receiving water body is <br />identified as a freshwater forested/shrub wetland and a freshwater pond within the City’s <br />Surface Water Plan. <br /> <br />Storm sewer infrastructure, including catch basin inlets and conveyance piping, exists within <br />the west portion of Jerrold Avenue and along Edgewater Avenue, both segments currently <br />having curb and gutter. The City’s Public Works Department conducted televising <br />inspections of the existing storm sewer and found these pipes to be in good condition, with <br />minor manhole repairs and replacement of existing castings necessary during reconstruction. <br />A majority of Glenpaul Avenue, eastern Jerrold Avenue and Prior Avenue have minimal or <br />no drainage infrastructure to convey runoff from the street pavement and adjacent property. <br /> <br />Storm sewer was installed along Lake Valentine Road during the 1995 reconstruction <br />project, and discharges to Valentine Lake. Pipe sections were found to be in good condition <br />based on an televising inspection by the Public Works Department. Inspection records <br />indicate the need for a minor manhole structure repair, removal of accumulated sediment and <br />two offset pipe joints of low severity. <br /> <br />The two project areas are not identified within the Flood Hazard Areas Map contained within <br />the City’s Surface Water Plan. The Pollutant Source Location Map identifies three potential
