potential variability of the subsurface conditions, additional drilling may be warranted; however, the <br />total linear footage will not be exceeded without prior authorization. <br />? Borings will be advanced with hollow-stem augers using an all-terrain vehicle (ATV)-mourited drill <br />rig. Standard Penetration Testing (SPT) samples will be eartracted at 2,5 ft intervals in the first 10 <br />ft and 5 ft intervals thereafter, in general accordance with ASTM D 1586. One 3-inch diameter <br />thin-walled (Shelby) tube is included in the investigation to collect an undisturbed sample of a soft, <br />fine-grained soil, in general accordance with ASTM D 1587. Soils will be classified in general <br />accordance with the Unified Soil Classification System (ASTM D 2487). <br />? Subsurface water levels will be measured during drilling and where possible, 8 hours later. Completed <br />borings will be backfilled with soil cuttings. <br />? URS will utilize available information on existing utilities and contact the Ohio Utility Protection Services <br />(OUPS) to locate and mark underground utilities before drilling begins. <br />? URS will perform an appropriate number of geotechnical classification and index property tests on <br />representative samples, to sufficiently characterize the subsurface conditions. Index tests will <br />include moisture content, grain-size, and Atterberg limit analyses, as appropriate. <br />A geotechnical 'summary letter of findings will summarize the findings of the subsurface exploration and <br />include descriptions of the general geologic setting, subsurface and groundwater conditions and a graphical <br />representation of the boring logs. <br />Task 3 - Preliminary Plan <br />URS will develop preliminary hydraulic modeling to test the effects of increased flood storage capacity <br />and control structures on culverts. Based on the concept plan included in the Grant Application, URS <br />will develop a preliminary grading and landscape plan for the Phase 1 project. URS will prepare cost <br />estimates based on the preliminary plan to monitor conformance to the project budget. URS will <br />prepare a color rendered preliminary plan for presentation to Mayfield Village and stakeholders. <br />Task 4 - Permitting <br />URS will prepare a Nationwide Permit Application to the Army Corps of Engineers for the Phase 1 <br />project area. URS assumes that the project will be covered under Nationwide Pernut 427 for Strea.in <br />Restoration. URS will coordinate with Corps personnel during the pernutting process. <br />Task 5 - Construction Documents <br />URS will prepare construction plans and specifications for the Upper 40 Stream Restoration Phase 1 <br />project. Construction plans are anticipated to include a title sheet, schematic plan, general notes, <br />tabulated quantities, site plan, grading plan, cross sections, landscape plan, and site details. <br />Construction specifications will be provided on the construction plans using 2002 ODOT Construction <br />and Material Specifications. URS will develop final hydraulic calculations submittal for review by the <br />City Engineer. Construction plans will be based on ODOT format. Plans and specifications will be set <br />up as a unit price contract in order to provide flexibility to make field directed quantity adjustments as <br />required during construction. <br />V:\BD.FY02\ENVIltO\EVANSWROPOSAL\P-UP40PH1.DOC Page 3 TIRS.
