V. PARKING ANALYSIS FINDINGS 



Parking demand associated with Aquarium visitors and employees was estimated 

 for botli average and peak summer weekday conditions and average and peak summer 

 Saturday afternoon conditions in the month of August, in both cases, a sensitivity 

 analysis of transit mode splits ranging from 15X to 25% was tested, and It was 

 assumed that 32.4% of visitation would occur in July and August. Estimated levels 

 of parking demand are shown in Table 9. Under a scenario of 2.1 million visitors, 

 approximately 700 spaces would be required during a typical weekday throughout the 

 year and nearly 1200 weekday spaces would be required In August at a 25% transit 

 mode split. Although Aquarium parking demand will be highest on Saturdays, the 

 weekday demand will determine the size of any needed parking facility. Because 

 significant amounts of the parking in the Navy Yard wi I I be dedicated to employees, 

 there will be excess space In the Yard to absorb the additional Aquarium related 

 parking demand on Saturday. The most likely location for providing overflow 

 parking within the Yard Is the existing Garage near Gate 5. Locations outside the 

 Navy Yard, including proposed new garages at North Station and Community College, 

 will also be evaluated.

The overall parking supply in the Yard will be in the range of 3600-4300 

 spaces depending on the amount of employee transit use and the amount of Joint use 

 between office and residential uses. (Joint use means that a parking space can be 

 used by both a daytime employee and a resident who drives his or her car to work 

 during the day and returns in the evening.) While up to 40% of the spaces could 

 be Joint iy used, there will st I I I be adequate overf low park Ing for the Aquar lum on 

 Saturday. 



During the week no excess parking will be available in the Navy Yard, and 

 the development of an Aquarium facility will require the provision of an average 

 700 spaces with up to 1200 parking spaces needed during the peak months of July 

 and August. The decision on parking facility sizing is an Important one for the 

 Aquarium. The construction of a smaller facility will require the Aquarium to 

 develop an extensive transit system if projected visitation levels are to be 

 accommodated. If a larger parking facility is constructed, it will, by Its very 

 existence, make higher levels of transit ridership harder to achieve. Therefore, 

 the Aquarium must decide on a marketing strategy before proceeding with a parking 

 faci I Ity.
