I WMA I cracking is observed, a sudden summer downpour can funnel surface water to footer drains in a matter of minutes. The area is populated by over 1,000 homes in the two (2) lift station areas. A roughly 10% sampling /inspection program of the home plumbing tie -in program may be revealing. The second related matter is the ability of the storm water conveyance system to carry water away from areas experiencing sanitary sewer overflows. An adequate combination of pipes, swales, gutters, and streams will relieve the water before it can build up sufficient hydrostatic water pressure to expose sewer system flaws (main sewer mains, lateral, or footer drains). In fact, this is discussed on Page 6 of 41 of the SSDCP Report. In this regard, the topography of North Olmsted is a prime indication of drainage challenges, both within in corporation boundaries and with neighboring communities such as Westlake. The third piece of the probe to control the sanitary sewer overflows involves the lift stations. For example, the Lebern lift station exhibits anomalies in its pump curve during high flows. This could point to a possible vortexing problem in the wet well. Also, flow rerouting could increase the ability of the sanitary system in general to transport and treat the flows without bypassing even with a certain level of extraneous flows. Summary Floyd Browne proposes a multi -task work plan as follows: A. Study /report/engineer plan review. Establish a baseline of information including particulars of probable home construction methodologies in the impacted neighborhoods. B. Staff meeting(s). Discussion with city staff to gather intimate local knowledge. This would include field visits. C. Issue Progress Report to the City. Preliminary findings and discoveries and refinement of anticipated work tasks. D. Investigation of residential units. In cooperation with the county health /plumbing department, inspect the internal plumbing layout of houses and assess the probable impact of footer drains /sump pumps /downspouts and other possible extraneous sources of water. Target (10% of houses). Document results in tabular form. E. Examine the storm drainage /runoff characteristics in the impacted areas. Perform a general analysis of what reinforcement or improvements may reduce hydrostatic pressure (water pressure) on the beleaguered sanitary sewer system network including footer drain contributions. Prepare a diagram of significant drainage features and promising enhancements that may improve efficiencies. F. Observe the functionality of the lift stations. Evaluate the internal workings of the pumping operation with an eye towards upgrading their capability. Externally, study options related to rerouting and /or reinforcing the discharge end of the lift station. G. Issue a preliminary report on the tasks outlined in Items A through F. Discuss with the staff and administration of the City. H. Issue a final report titled Plan of Study by January 1, 2006 for submittal to the City to forward on the Northeast District Office of Ohio EPA. I. Meet with Agency to discuss the report. (This will conclude the proposed Plan of Study phase. The additional tasks outlined below are NOT part of the work plan at this time) The conclusion of Items A through I will set the stage for the development of a Final Schedule to be submitted to Ohio EPA no later than May 1, 2006. Progress Reports are to be submitted on January 1St and March 1St, again as requested by Ohio EPA. The breath and scope of the Final Schedule will be determined by the outcome of the Plan of Study phase. The work effort after the Plan of Study is submitted will include: responding to Ohio EPA comments, developing budget projections, strategy for dealing with residential footer drains (possible expanded inspection program), conceptual plans for lift station improvements, and conceptual plans for storm system design and engineering solutions for your world
