Subsection 214-3-3.51 - INVESTIGATION; FOUNDATIONS; CONSTRUCTION MATERIALS, SURVEYS; AND HYDROLOGIC CALCULATIONSa. The owner shall complete all investigations prior to submitting the design report. The scope and degree of precision required is a matter of engineering judgement based on the complexities of the site and the hazard potential classification of the proposed structure. The geotechnical engineering investigation shall consist of borings, test pits, and other subsurface exploration necessary to define adequately the existing conditions. The investigations shall be performed so as to define the soil, rock, and groundwater conditions.b. All construction materials shall be adequately specified to insure that their properties meet design criteria. If on-site materials are specified, they shall be located and determined to be adequate in extent and in properties.c. Surveys shall be made with sufficient accuracy to locate the proposed construction and to define the volume of the storage in the impounding structure. The area downstream from the proposed impounding structure shall be investigated in order to delineate the areas and extent of potential damage in case of failure. Locations of center lines and other horizontal and vertical control shall be shown on a map of the site.d. The drainage area shall be determined. Present and projected conditions shall be reasonably considered in determining the runoff characteristics of the drainage area. All hydrologic assumptions shall be included in the design calculations which shall be submitted as part of the design report.e. Periodic inspections will be conducted by a qualified Dam Inspector during the construction or reconstruction of all dams in this State. Additionally, written reports noting all conditions found will be forwarded to the Director, MEMA, within 15 working days. Conditions affecting public safety of employees shall be forwarded to the Director at the earliest opportunity. C.M.R. 15, 214, ch. 3, § 214-3-3.5, subsec. 214-3-3.51
