APPENDIX B BRADLEY ROAD AND WINDSOR DRIVE CULVERT REHABI LITATION Scope of Services Intent of the Professional Design Services This project consists of the preparation of design plans and specifications for the rehabilitation of two multi-plate steel arch culverts. The first culvert is located on Bradley Road over French Creek, north of 5740 and 5747 Bradley Road. It consists of 62 feet of a 16' span x 5'-2" rise culvert. This corrugated steel culvert has deformed in several areas along the sides and top, and all of the interior joints are leaking and corroding. Road de-icers are probably causing the corrosion. A, determination of what repairs are required is needed. An option for lining the culvert should be considered since a significant portion of the flow through this culvert has be;en diverted to another channel. The extensive silt buildup in this culvert will need to be removed in order to install a liner pipe. It is planned to install sidewalks on both sides of Bradley Road, so the design plans shall include proposed sidewalks over the culvert. A chain link fence should be added in front of the headwalls to protect pedestrians on the sidewalk. A request will be made to Cuyahoga County for their participation in the construction funding for this culvert. The second culvert is located on Windsor Drive over Westerly Lateral of Rocky River, east of 28415 Windsor Drive and 6177 Forest Ridge Drive. It consists of 102 feet of a 16' span x 4' 7-1/2" rise culvert. The pipe joints under the roadway have almost rusted through. Since the deterioration appears to be caused by road de-icers and there is only a small amount of fill on the culvert (1.3 feet at center, 6 inches at edges), it is recommended the roadway area be excavated and a waterproof inembrane placed over the culvert. There is also a silt buildup at the outlet that needs to be removed. Plans of the existing structures are available for review at the North Olmsted Engineering Department. -Wo
