META Mousing —Santa Ana Arts Collective Parking Analysis <br />April 20, 201 G <br />Page B <br />analysis will focus on arrival rates since a primary concern of most destinations is allowing visitors /residents <br />efficient access to the site efficiently. <br />Visitor /Employee Parking <br />As it relates to the ten visitor parking spaces and three employee spaces, industry standards indicate that the <br />average vehicular headway for a free -flow system without vehicular control gates is estimated to be <br />approximately 3.6 seconds per vehicle, if there is easy direct approach and no sharp /difficult turns into /out of <br />the property. This equates to approximately 1,000 vehicles per hour per lane (60 seconds x 60 minutes = <br />3,600 - 3.6 seconds = 1,000 vehicles per hour). <br />Conservatively, an assumption of 80% peak -hour traffic factor is used when considering the maximum traffic <br />volume rate. Normally the traffic volume will be at a much lesser rate throughout the majority of the day, but <br />80% is being used as a conservative estimate for the purpose of this report. At 80% the maximum design rate <br />is estimated to be, approximately 800 vehicles per hour. <br />Residential Parking <br />As it relates to the 99 residential parking spaces located in the subterranean level, industry standards indicate <br />that the average vehicular headway for a gate - controlled system is estimated to be approximately 8.9 seconds <br />per vehicle, if there is easy direct approach and no sharp /difficult turns into /out of the property. This equates <br />to approximately 1,000 vehicles per hour- per lane (60 seconds x 60 minutes = 3,600 _ 8.9 seconds = 405 <br />vehicles per hour). <br />Conservatively, an assumption of 80 °% peak -hour traffic factor is used when considering the maximum traffic <br />volume rate for this type of affordable housing residential property. Normally the traffic volume for this type <br />of housing will be at a much lesser rate throughout the majority of the day, but 80% is being used as a <br />conservative estimate for the purpose of this report. At 80% the maximum design rate is estimated to be <br />approximately 324 vehicles per hour. <br />Parking Control Service Rates <br />The following are the anticipated parking control service rates for the visitor, employee and residential parking <br />at the Meta Housing — Santa Ana Arts Collective: <br />31 D -32 <br />
