.~ <br />Plan of Study for City of North Olmsted Phase I by Floyd Browne Group January 4, 2006 <br />RESIDENTIAL HOME INSPECTIONS AND SANITARY SEWER EVALUATION <br />LeBern Pump Station Service Area <br />Overview <br />The LeBern Pump Station Service Area is located north of Lorain Road and bounded on the <br />east by Fairview Park, on the north by Westlake, and on the west by Columbia Road (see <br />Exhibit 1). Within this service area, there are approximately 2,150 homes, 5-6 businesses, and <br />two schools. Based on the Ohio EPA Flow Guide, the estimated residential equivalent units <br />(REUs) are 2,200. An REU can be defined as the normal amount of wastewater flow expected <br />to be discharged from a single family home on an average day. The Ohio EPA Flow Guide <br />states that this amount is 400 gallons per day. Businesses, schools, and other institutions are <br />rated on this same system as equivalent units. Two (2) trunk sewers with one on Clague Road <br />and one (1) on Walter Road serve this area. <br />The ground generally slopes north from Lorain Road at elevation 750 to the LeBern Pump <br />Station at elevation 730; however, there are many flat areas that are poorly drained such as <br />Deerfield Estates and Maple Ridge. The soils in the area are classified as poorly drained as <br />detailed in the section on the storm sewer system. The sanitary sewer records indicate that a <br />layer of shale exists approximately 5-10 feet deep and a layer of rock at 15-20 feet deep <br />throughout the area. The local sanitary sewers have been installed above the rock in most <br />areas, but the collector lines and the trunks have been laid in or just above the rock layer. <br />Larger diameter pipes at minimum grades have been constructed to provide the necessary <br />design capacity for the system. On many streets, stacks have been installed to permit the <br />homeowners to tie into the system above the shale layer. <br />The homes in the LeBern Service Area were generally built in the 1950's and `60's when <br />connecting foundation drains to the sanitary sewer was widespread and common practice. <br />There are a variety of home styles such as ones built on slabs or crawl spaces, split levels, and <br />full basements. The reason for these different designs may be due to the level of the rock or <br />sanitary sewer on each particular street. These differences required the study team to <br />investigate different types of homes in the area asking the question: "Why did this one <br />experience flooding and this one did not?" <br />The residential home surveys were obtained over the phone, by going house to house, and by <br />mail. The study team attempted to contact a random group of residents throughout the area <br />with a special focus on those who had experienced some sort of flooding during the August 20, <br />2005 storm event. However, the team wanted to have some idea of why certain homes in a <br />particular area did not flood. A letter from the Mayor (see Exhibit 2) was distributed explaining <br />the study, and a questionnaire (see Exhibit 3) was filled out on each property including <br />observations around the home and in the basements. Exhibit 4 shows a typical house <br />schematic that visually displays the down spout drains, foundation drains, sanitary sewer lateral, <br />and sump pump discharge in relationship to the house and the main line sewers in the street. <br />Copies of the surveys are included in Appendix A and a summary of the results is shown in <br />9 <br />
