I PART II KARTH LAKE EAST NEIGHBORHOOD IMPROVEMENTS I I I I I I II I I I I I I I , I A. Background Summary The Karth Lake East was identified for pavement rehabilitation in 2003 as a part of the five'year PMP schedule devcloped by the City Engineer in the Spring of 2002. This neighborhood includes streets that meet City standards for width, curb and gutter and drainage infrastructure and is therefor been identified for overlay, Neighborhood streets that are being considered as a part of this feasibility report are listed as follows: Street Name Karth Lake Road Pleasant Circle Amble Circle Pleasant Drive (N,S) Pleasant Drive (E,W) Amble Drive PCl 2002 65 63 72 59 26 89 Notes: Last Significant Road Work 1978 1978 1978 1978 1978 1994 Proposed Improvement M&O M&O M&O M&O Reconstruct Nothing a) Amble Drive is located within the Karth Lake East neighborhood however was reconstructed with curb and gutter and stonn sewer approximately 8 years ago and is therefore not being considered for further improvements at this time. b) The east-west segment of Pleasant Drive is significantly more deteriorated than the neighborhood streets as a whole as is evident in its PCl rating. For this reason, it is recommended to be reconstructed as a part of this project. Mill & Overlay of this segment of Pleasant Drive is included as an alternative for Council consideration. The neighborhood as a whole is ranked as the highest priority for mill and overlay rehabilitation based upon the 2002 street condition assessment. All of the project streets with the exception of the east west segment of Pleasant Drive have PCl ratings in the lower part of the overlay range, The goal of efficient pavement management is to rehabilitate pavements with relatively low cost overlays when PCl ratings are in the range of 60,80, Once pavement PCls drop below 60 the annual rate of deterioration increases often to a point where overlays are not effective and reconstruction is necessary, The City Engineer assesses street conditions on a three year cycle is to identify streets and neighborhoods which are approaching this zone of opportunity, The project streets recommended for mill and overlay have PCl ratings between 59 and 72, The east-west segment of Pleasant Drive has a PCl of 26 which is significantly lower than the other streets and well within the typical range of reconstruction, This segment also exhibits a significant amount of misaligned curb and gutter (approximately 30% of the total) creating numerous "birdbaths" after rain events, Although it is possible to repair only the curb segments which have settled, this cost per foot is typically three 13
