Moves moderate traffic volumes at moderate <br />speeds generally shorter distances. <br />Class V (Local Streets) <br />Move low volumes of local traffic at low speeds over short <br />distances and provide direct access to and from individual <br />properties. <br />♦Arterials, freeways and expressways should be located so as to <br />bound rather than bisect residential neighborhoods. <br />•Residential setbacks from elevated or grade level /reeway, <br />expressway and arterial streets should be a minimun of 150 <br />feet to minimize noise levels. Landscaping should .be requir­ <br />ed to further reduce noise levels. <br />•All circulation systems should be coordinated with those of <br />adjacent communities, the metropolitan and County systems. <br />- 37 -
