- Not covered here: Residential (Table 2-3), office (Table 2-5) and special purpose (Table 2-8) tables have no Emergency shelters row, so the use is not listed there (blank-equals-not-allowed rule; see 22.04.020(h), text not in packet).; TCSP and SP districts follow their specific plans.; Table 2-3 does not list the mixed-use (TCSP) and specific plan (SP) districts..
