PROPOSED STREET CONSTRUCTION I. GENERAL COMMENTS City staff has worked closely with the neighborhood in an effort to develop preliminary plans that meet the needs of both the neighborhood and the City at large. Because this is a Municipal State Aid (MSA) roadway and we intend to utilize state funding, the roadway must be constructed to meet minimum state standards. The preliminary design, as presented in this report, meets all applicable guidelines. In an effort to minimize disruption to the adjoining landscape and adjacent property owners it is proposed to construct portions of this roadway to the narrowest width allowed by state standards - 26 feet. In accordance with state standards, it is proposed that parking not be allowed unless additional width is provided. The roadway will be constructed with a 9-ton structural design, bituminous pavement, and concrete curb and gutter. The concrete curb and gutter will be of the B618 straight-back type and will be constructed on both sides of the roadway. With the exception of the segment of road that cuts through Ladyslipper Park. The B618 curb style provides an edge guide for snowplow equipment, minimizing sod damage. The new curb and gutter will be matched into existing curb and gutter on adjacent streets. Existing street grades will be altered where appropriate to improve drainage. Such changes in street grade will be designed to keep driveway approaches at a reasonable grade - preferably less than 10%. In many cases, minor grade changes on the roadway will result in more reasonable driveway grades. The existing manholes, fire hydrants, gate valves, and other similar structures will be adjusted as necessary as part of this project. The sanitary sewer mains have been televised, and those portions of the sanitary sewer mains that are in disrepair will be replaced during construction. In addition, those residents with roots in their sanitary sewer services will be given an opportunity to replace their services at their expense. The watermain between the railroad tracks and Dale Street ofthis project needs to be replaced. The cost of any watermain or sanitary sewer main replacement will be excluded from the MSA portion of the project and financed by the appropriate utility fund. If unsuitable material is encountered beneath the existing pavement during construction, it will be removed and replaced with suitable backfill material. Any sod that is damaged as a result of the project will be replaced. In order to match the new street, driveway approaches will be removed approximately between the existing pavement and the property line. The removed driveway will be replaced with similar material - asphalt or concrete. Project P-ST-SW-05-06 S. Owasso Boulevard Reconstruction Feasibility Report 17
