Project AH-07-07 . 2007 Pavement Management Program EXISTING STREET CONDITIONS The project areas include single family and commercial properties, along with some City-owned parcels. Most of the neighborhoods are fully developed. All of the streets are delineated with concrete curb and gutter; there are no existing sidewalks or paths along the streets. The residential streets are typically 34 feet wide. Connelly A venue is approximately 36 feet wide and Pine Tree Drive is approximately 42 feet wide. Many of the residential streets have cui de sacs, and therefore, carry low volumes of traffic. Arden Hills' pavement management system utilizes a pavement condition index (PCI) rating of 0 to 100. This rating is based on surficial pavement observations. Generally, the indices correspond to a level of most cost effective improvement as follows: 0-30 = pavement reconstruction; 31-65 = asphalt overlay; and 66-100 = sealcoat and/or crack sealing. This rating system a<;sists in prioritizing roadway improvements and projecting costs for use in the City's pavement management and capital improvements plan. Actual levels of improvements are determined by completing a comprehensive geotechnical evaluation and a preliminary engineering report. Soil borings have been scheduled for the week of January 8, 2007. The results will be provided to the City the week of January] 5, 2007. Stair will review these results to verify that the . recommended improvements as described are appropriate. If any modifications to proposed improvements are needed, these will be presented at the Public Hearing. Katie Lane and Katie Court Katie Lane just east of Cleveland shows signs of distress, such as alligator cracking and potholes. Continuing east, the amount of distress decreases, however, pavement cracking is still present. There is evidence of previous maintcnance, including crack sealing and seal coating. There is minimal cracking on Katie Court, but the pavement surface shows signs of oxidation, as evidenecd by the exposed pavement aggregates. Prior maintenance on Katie Court includes crack sealing. Brighton Way Brighton Way shows more significant signs of distress, ineluding transverse cracking, alligator cracking and potholes. Some of the pavement has also settlcd, creating drainage problems and edgc cracking. Settlement and ponding is especially noticeable in the northern cui de sac. Prior maintenance includes pothole patching, skin patching, crack sealing and seal coating. Pine Tree Drive and Harriet A venue Cracking is visible on both Pine Tree Drive and Harriet A venue. Some minor potholes are present on Harriet Avenue, and Pine Tree Drive has some uneven pavement, crcating dips in the pavement surface. There is evidence of crack sealing, seal coating and minor patching along both . of these streets. 15
