Plans For Gaza, #1 Parking Lot

OVERVIEW
Parking as part of an overall transportation system is one of the crucial issues of our times. As the number of automobiles increases exponentially, the need to house them in close proximity creates a challenging design problem. The parking garage or lot must foremost deal with the Functional/Operational - as in providing for safe and efficient passage of the automobile. This is a very complex challenge as automotive, engineering and traffic issues relative to site locations must be integrated to create the appropriate solution. Therefore designing the parking garage requires an integrated design approach of many professionals. Parking has often been reduced to the construction of the most minimal stand-alone structure or parking lot without human, aesthetic or integrative considerations. This has given parking a poor public perception and has frequently disrupted existing urban fabric. However, many architects, engineers, and planners have envisioned and constructed far more complex, aesthetic, and integrative structures. This should be the goal of good parking design.

BUILDING ATTRIBUTES
Although parking garages can take many forms as stand-alone or part of a mixed-use structure, self-park or valet, and automated in urban or rural settings, all parking garages should seek to meet the following basic criteria:

Functional Requirements

The garage should account for the complex spatial needs of the driver and the automobile:

The size, height, and turning radius of current automobiles as well as past and future trends of automobile size and statistical quantity must be taken into account these are called parking geometries.
There are many ramp design configurations and different ones are appropriate for the primary purpose of the facility to insure that your intended use is compatible with ramp design.
The streets surrounding the garage and their traffic flow must be taken into consideration when planning entrances and exits and deciding on ramp designs.
The entrances and exits are very important to the smooth functioning of the garage, with the type of use again determining the length from the opening and placement of the entry booths, as well as the quantity of entrances and exits.
The type of equipment and the necessity of a booth and office are also determined by the garage use.
Zoning issues require the number of spaces for parked automobiles. The designer must work within local codes to meet these requirements.
In mixed-use projects there has been shared parking documenting how different users can maintain full garage occupancy, such as movie/theater goers, night use and residential use during the day. This can be calculated to the advantage of the garage owner and the community by eliminating the empty night garage syndrome.
Optimizing site potential, by choice of site and its relationship to walking, driving, other transportation linkages and good design opportunities.
The operation and maintenance of a garage is very critical. Revenue control equipment and other issues related to the smooth functioning of the garage must be taken into account during the design process.
