used in the Administrative Rule and if not used, remove the terms from <br />Section R-9.6710-A. <br />Finding: The term "complex project" is not used in the Administrative Rule and has <br />been removed from Section R-9.6710-A. The term "design area" is used in <br />.. the Rule. <br />Comment 3: R-9.6710-A. Design Area: Clarify the intent of the definition that states "and <br />maybe randomly distributed throughout the development site." <br />Finding: The definition has been modified. Development sites may have multiple soil <br />types randomly distributed throughout the site with similar design constraints. <br />Evaluation of the design criteria for the entire site is required.. <br />Comment 4: R-9.6710-A. Engineering Properties of Soil and Rock: the proposed <br />Administrative Rule does not provide the quantitative standard method to <br />determine erodibility. <br />Finding: The professional is responsible for providing quantitative measures and <br />identifying the standard by which they made the determination. Design <br />professionals are encouraged to maximize their data collection according to <br />the needs of the project, i.e. an erodibility measure that is necessary for <br />erosion prevention permit application. No change is being made to this. <br />provision as a result of this comment. <br />Comment 5: R-9.6710-A. Engineering Properties of Soil and Rock: Void ratio is an index <br />property not an engineering property. Recommendation to use Terzaghi, <br />Peck and Mesri definition from "Soil Mechanics in Engineering Practice", 3Ta <br />Ed. <br />Finding: Void ratio has been removed from the list of engineering properties and <br />added to the list of significant index properties. The definition for index <br />properties provided in the Administrative Rules is consistent with Terzaghi, <br />Peck and Mesri's definition. <br />Comment 6: R-9.6710-A. Expansive Soil: Delete reference to "excessive" expansion and <br />shrinking. <br />Finding: Deletion made. <br />Comment 7: R-9.6710-A. Qualified Registered Professional: Recommended alternative <br />definitions by a number of people submitting comments. <br />Finding: EC 9.6710(2) establishes that the geological and geotechnical analysis can be <br />prepared by an Oregon licensed Engineering Geologist or an Oregon licensed <br />Civil Engineer with geotechnical experience; the Rule. describes these two <br />professionals under the general term "Qualified Registered Professional." <br />The Rule cannot alter the code provisions establishing who is allowed to <br />prepare an analysis. No change is being made. to this provision as a result of <br />these comments. <br />Administrative Order - 2 <br />R:WDMINORD\RULES\03geotech2ao.wpd(03/26/03) <br />
