Mr. Loudin: Pursuant to the Mason County Environmental Policy Ordinance and State Environmental Policy Act (SEPA) , environmental review is required for this development. I have enclosed an environmental checklist which should be filled out and returned to the county at your convenience. Please answer all questions as completely as possible in order to eliminate potential delays in processing. Upon receipt of the checklist and evaluation, a threshold determination will be issued. Processing time is dependent on the determination but will include posting of the site and acceptance of public comments. If you have any questions feel free to give me a call . Thank you.

"Chet's Trusses" Minimum guidelines for stormwater management. Inadequate permanent stormwater management plan. Mason County has reviewed the proposed stormwater drainage plan prepared for "Chet's Trusses." The proposal does not meet minimum County requirements for commercial site developments. Commercial sites are required in the Mason County Parking Standards (Ordinance No. 815) to retain surface water runoff on site or dispose of it into an area approved by the Mason County Engineer. Recognizing that many areas of Mason County do not readily lend themselves to infiltrating stormwater runoff, Mason County Public Works has allowed discharges from commercial sites to occur if the rates of discharge from the site conform to Puget Sound Water Quality Authority (PSWQA)downstream erosion control standards. These standards underlie the requirements contained in the Stormwater Management Guidelines distributed by the Mason County Department of Community Development. The PSWQA Technical Manual (III-1.3 Minimum Computational Standards) requires; 1. For all computations, except for basin plans or equivalent, the minimum standard shall be the Soil Conservation Service Unit Hydrograph (SCSUH) method (1) with the level pool routing method, or equivalent hydrograph techniques, subject to approval of the local government. The Santa Barbara Urban Hydrograph (SBUH) method is also an acceptable method. A computer simulation using the information submitted by Consolidated Engineering input into the SBUH method, indicates that the proposed facility exceeds predevelopment discharge rates by appreciable amounts. Other concerns include; 1) In calculating the pre-development runoff, it appears to only address the runoff from the front half of the property, then applies a 5 year event rain intensity to the site. It would be to the proponents advantage to use the full site in determining pre-development discharge rates. The employment of a 5 year storm event has little relevance in this site's analysis. 2) Catch Basin #4 discharges stormwater from the site to the north without any control feature. Recycled page2 RB 3) The extent of material to be excavated/graded cannot be determined from the plan sheets submitted. Sheet 2 of the drainage plans shows three elevation contour lines and indicate that a 25 foot cut will be required for the building. Where this borrow material is to be deposited is not indicated on the plans. If all the material is to be removed off site, then the receiving site should be identified and permitted if necessary. There is a remote possibility that the three contour lines fully describe the surface topography, but there is no indication of the frequency of the contours or their relative elevations. The contour lines need labeling. If the entire area contained within the contour line shown in the northeast corner of the property were excavated 25 feet deep, the volume would be approximately (1/2)x(70x8Ox25)/27=2,590 cubic yards. In addition, there is no evidence for provision for temporary erosion and sediment control. At a minimum: An ESC plan should show limited construction access to the site, provide for the covering of soils if they are to be exposed for more than 2 days, retention of sediment on-site through the use of structural and source control BMPs, maintenance of erosion and sediment control BMPs through regular inspection. In summary, the stormwater plan needs further designing and information needs to be submitted to facilitate calculation of earthwork quantities.
