HomeMy WebLinkAboutFPA2016-00004 Stormwater Plan - FPA Storm Water Plan - 9/20/2016 Mason County Review Checklist For a Stormwater Plan G�5 Instructions: This checklist is intended to assist Staff in the review of a Stormwater Plan. The Stormwater Plan is reviewed for completeness with respect to the 2005 Department of Ecology Stormwater Manual. If an item is found to be not applicable, the Plan should explain the basis for the conclusion. The Plan is also reviewed for clarity and consistency. If the drawings, discussion, or recommendations are not understandable, they should be clarified. If they do not appear internally consistent or consistent with the application or observations on site, this needs to be corrected or explained. If resolution is not achieved with the author, staff should refer the case to the Planning Manager or Director.

Reviewed by on Time spent in review: SECOND REVIEW/UPDATE: Reviewed by on Time spent in second review: THIRD REVIEW/UPDATE: Reviewed by on Time spent in third review: Disclaimer: Mason County does not certify the quality of the work done in this Stormwater Plan. Page 5 Form Effective May 2009 Butch, I just finished going through N.L. Olson's stormwater and erosion control plan submittal checklist and I am not able approve the document as complete. For this to make sense you need to know that we Mason County planners are not engineers, and we rely exclusively on the submittal checklist review to determine if an engineered stormwater and erosion control plan is fully compliant with County requirements. We simply are not qualified to read through the documents and make a determination unaided. In this case, I see that the engineer left a large number of items unchecked, particularly in Section II. I realize that many of these items may not apply to your situation and in that case the engineer needs to provide a written acknowledgment when a checklist item is not applicable. Please have the engineer address all of the following items in the form of an addendum (if needed)and a completed Submittal Checklist. Here is the list: Section I La through c; I can't not certify that this has been done for all elements. 12-point required elements; Items 3 through 12 have not been addressed. The engineer needs to direct the reader to the location in the Narrative where the element is discussed or explain why it is not required. 2.(b): Answer was omitted. 4.(d): DNF discussion of adjacent residential areas. 4.(f): Other? 6.(c): and(d): DNF discussion of Erodibility and Settleability. 8.(b): DNF discussion of phasing(if any). 9. I and II: DNF discussion of construction schedule (if any). 10. (a), (b), and(c): DNF 11: Operations and Maintenance: I will attached the O & M Covenant form that is needed for this item. LINK Section II 3.(d), (e), and(f):Needs to be addressed. 4:Needs to be addressed. 5: (a)through(m): Needs to be addressed. 6 through 8: Needs to be addressed. Also,the checklist isn't stamped. Here is a link to fresh checklist. Please have the engineer stamp the last page and return it to me. LINK One other thing: I noticed on the Submittal Checklist that 2,200 cubic yards of earth will be cut and filled. This requires a Land Modification Permit. I see that one has not been r permission, I will applied for et. I will attached a link for that application. With your e s pp Y pP Y p also modify your SEPA checklist to include this in the project description, as over 500 cubic yards of cut and/or fill is subject to SEPA review. LINK Let me know if you have any questions.
