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