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