(SDC 4.2-105 A.4.a-d)◦Where the Public Works Director determines that a TIS is necessary to support a request for a Variance ◦When a land use would be estimated to generate 1,000 or more vehicle trips per day or 100 or more trips per hour in the peak hour◦Where the Public Works Director determines that a TIS is necessary to address known traffic safety or street capacity concerns associated with the proposed development◦The Director, in consultation with the Public Works Director, may modify TIS requirements consistent with TransPlan and the intent of this Code when existing conditions make their strict application impractical or inconsistent with accepted site planning or transportation planning principles.Attachment 1-21
