Planoirta Diroctor <br /> SUBJECi: C8-66-II Special Pre-f�lixed Ccncrete Provisions DAYE: Qec, 22. :900 <br /> On Decesrsber 6, l9bb a public hearing eias held before tho City Planning and <br /> Zontng Corrmission on a proposal to amend Chapte; 23 of the7ucson Codo to permit <br /> cortain typos ot concrete mixing and rotailing in 8-2A genoral business zones, <br /> The pub! ic hearing was closed and it was <br /> AGREED: To send this matter back to staff for furthe� study and consultation <br /> with the tnspactions Dopartmont and instruct si�aff to prep�re a <br /> revised ordinance i'o be submittad to tho Ccnmiesion at tho next study <br /> sassion in January. <br /> Statf has roviee�ed this matter and feels that thore are certain poini�s that <br /> ' should bo clarified, such as this appearing to be prinarily an industrial use, <br /> its compatibility with B-2A uses, tho emission of dust during 000ration of tliis <br /> use and tho ability to adequa�oly enforce aciy restric;ions as to tbe emission of <br /> dust, noise, odor, etc. <br /> Although it has been rocognized th�t concroto mixing in bdich plants is a� <br /> industrial uso, thero has been proser.tod to us a nee� type of cor�creho batch <br /> " operation erhich does not necessarify fall within the ordinery ccnco�tion of an <br /> industrial use. This is an operation that mixes concreto in subsfian•tially <br /> limited quantifiies for sale to tho general public. <br /> As ;his concseto mixing operotion is proposed �o bo done in a vary limited <br /> m.anner, and tho product is mero in the nai•ure of a retail produc•h, it ie fo!' <br /> th�t, with adequata control, this use tvould be compatiblo with othor uses in the <br /> B-2A general businoss district. Tha omission of dust can bo cont;oilod by en- <br /> closing the hoppor, convoyor- bc�lts, bucf�ei• linos or other r.^.oans oi transperting <br /> the ma'rerial . I1• should be noted that it is nearfy impossiblo to �r:,ko this 'typa <br /> of operation fiotally dust tree, but stsff foels that tho relative ar�ount of dus•t <br /> emi+ted with the proposed controls uould ba negligiblz. <br /> The traosportation o: tho corcreto from the mixing plant to the building <br /> ' sito Would be done by the person buying concrei�e rather Shan having a transit-mix <br /> - ` truck detiver the concrete as has boen tho procedure nermall;� follo::�ed in tho <br /> past. 7his could be insured by limitlnc� the size of the vohicio usod to trans- <br /> port tho product to a capacity of ono cu6ic yard or less and also limitinc� tho <br /> total load to no rtare than 4,2GO. Ibs. <br /> in a-der that any adverse effects of tnis operation be adequately mrttrolled, <br /> 1 staff recan;rands that the Park .lnductriai perfermance sfianderds as found in <br /> Sec. 23-391( IS) through Sec. 23-391(2•S) opply to this use. By aoplying those It <br /> is folt that it eroutd give �ha Inspections Division some dafinito standards znd <br /> moasurements io �vork �+ith rzther than having to rely upon what might possibiy be <br /> construed as an arbitrary judoer,.ent of tno building inspector as to i•ihat is . <br /> obnoxious or harmful and e;hat is not. Hotrover, even teith thase eontrols, tho <br /> Chiei {nspector. kr• Hi99inbotham, feels ihat this use could be abusod and night <br /> oossibly devetop ini'o a full scc{e indus�r;ril ,operation. 7he planning staf? 4ests <br /> ;hat tha controls as proposed r:ould malce ;his ocona'aically unfeasibio. <br /> _ � _ <br />
