If a strip map submission contains adjacent altered speed zones situated both within and outside the corporate limits of a city, the district should send two prints or an electronic version of the strip map to TRF for review. When TRF and the district have reached agreement on the proposed zones, the district should then request the city to pass an ordinance establishing the zones within the city limits and TRF will write the necessary commission minute order. If there is an immediate need to post the speeds set by ordinance, signs may be installed for these zones prior to receiving a commission minute order on the adjacent section, as long as the city zone and adjacent existing rural zones are compatible.
