During the June 6 meeting with the Planning Commission and subsequent to the meeting, John Thompson of Marshall Concrete has responded to the various issues raised. One of the contributing factors to the dust problems is the outdated dust collector system on the e,-,dsting silo. A new collection system has been ordered and will be installed by December 1, 2002. The new silo will have a properly sized dust collector. Staff noted that dust generated from on-site traffic can be reduced if the traveled portions of the ske are paved. As for traffic impacts on 140th, all Marshall-trucks have been instructed to use the Unity Street access only; occasionally the 140th Avenue access is used for delivery of raw materials to the site. The company's plan is to construct bunkers adjacent to I40th that will provide a permanent position for aggregate storage and at the same time provide a screening wall adjacent to [40tl~. On September 10, the City Staff received a Site Plan and Grading, Drainage and Erosion Control Plan from Marshall Concrete. The Plans were prepared by Hakanson Anderson Associates and are dated August i4 and August 23,2002, respectively. The Site Plan identifies the development of 3 new bunkers for raw materials parallel to 140th Avenue N.W. A new berm will be developed between the material bunkers and 140th Avenue N.W. The height of the berm/bunkers is 10 feet, as measured from the top of the street curb to top of bunkers. The existing trees along t40th will be salvaged and worked into the new berm. This new bunker/berm plan will provide for more orderly storage of raw materials, minimize noise levels, and significantly increase the screening provided on 140t~. The material bins shown just north of the new bins will be removed. A concrete su. rface will be installed south and east of the building and existing pavement. The site improvements are substantial and the Applicants have requested a phasing plan: Phase ~ Install silo f6~tings and silo' Fall 2002/Spring 2003 ' Phase II Install material bunkers and berm Summer 2003 "Phase'~I [nstalla.t..!on of concrete surface Sp. ri~g 2004 Recommendation: The Planning Commission recommends approval of the proposed condkional use permit, as amended, contingent upon obtaining a variance to the height restrictions. The Applicant's request for a phasing of the required site improvements was subsequent to the Planning Commission meeting. Council Action: Motion to adopt Resolution #02-09- adopting Findings of Fact # relating to the request for a conditional use permit to expand the ready-mix plant at 14141 Unity St. N,W. to include a second product silo. and I I I I I I i I !
