MLTA Housing — Santa Ana Arts Collective Parking Analysis April 20, 2016 Page 7 Traffic Intensity Factor (T1F) Analysis (aka Traffic (Queue Study) The following is a review of the traffic intensity of the proposed Meta Housing — Santa Ana Arts Collective Parking Facility. When designing a parking facility it is critical to consider the external traffic flow, internal traffic flow and the ingress /egress control plazas. This will result in a parking facility that will provide the highest level of user comfort and convenience. It is also critical to understand the TIF for the parking facility. This calculation takes into consideration assumed peak -hour traffic volumes, along with ease of traffic flow which depends on the type of parking operation It is, e.g, free parking, paid parking, short -term (shopping patrons /visitors) and long -term parking (employees), etc. The proper design of the vehicular ingress /egress control plazas ensures desirable traffic flow. Consideration of the user - groups is important. For Instance, some facilities may not require gate - controlled access, whereby traffic has a free -flow style. Other facilities may require gate controls to realize revenue potential or to control user -type parking areas, e.g, residents, long- term/employee parking, nested parking areas, short- term /visitor parking, etc. Project Description The Meta Housing — Santa Ana Arts Collective will be an affordable housing /adaptive re -use project that will have one (1) van accessible space located at the Grade Level and 112 parking spaces in a one- level, subterranean parking garage. Of these, ten (10) spaces will be reserved for visitors and three (3) spaces will be reserved for employees. These thirteen (13) spaces will be located outside of the gated controls (see Exhibit "A ") and will have free -flow vehicular ingress /egress. The residential parking will be located in a reserved parking area that will have vehicular gate controls for ingress and egress. The proposed vehicular access will be via one entrance gate and one exit gate. The gates will be traditional sliding gates as are normally used in multi - family residential properties. These vehicular gates are proposed to be controlled by typical garage door openers. The opening of these gates typically takes approximately five to ten seconds. This is normally how gate - controlled entrances and exits function. High speed gates for this type of project are cost prohibitive. Specifically, this review will include confirmation that the vehicular access lanes will be adequate in regards to the parking control service rate for the parking components of this affordable housing residential project.
