Filing 4 Traffic Memorandum
Off-Street Parking
Filing 4 will provide a total of 601 off-street parking spaces to support the development. This includes a mix
of compact, garage, and accessible spaces as required. The project proposes a parking ratio consistent
with site needs and in conformance with national standards. The proposed development is 413 units which
would represent a parking ratio of 1.45 spaces per unit. The ITE Parking Generation Manual 5th edition was
consulted for comparison to the proposed parking ratio. The following ratios are provided for the multifamily
LUC used within the analysis:
Weekday Average: 1.31 spaces/DU (542 spaces)
Weekday 85th Percentile: 1.47 spaces/DU (608 spaces)
Saturday Average: 1.22 spaces/DU (504 spaces)
Saturday 85th Percentile: 1.33 spaces/DU (550 spaces)
As can be seen with the national data the proposed parking ratio is greater than or in line with the proposed
parking supply.
Analysis of Future Conditions with Filing 4 Site Development
Consistency with MTIS
Future levels of service with the proposed development plan were estimated based on the future traffic
volumes shown on Figure 4 and the HCM 6th methodologies for signalized and unsignalized intersections.
The results of these analyses are provided in Attachment II and presented in Table 4 and Table 5. As
mentioned, the existing volumes in the MTIS are greater than the recent data collection associated with
Montava and the approved and proposed filings represent fewer units and trip generation than the approved
MTIS. These two factors confirm that the approved MTIS provides a more conservative analysis of the first
four filings originally studied.
Total Future 2023 Operational Analysis with Proposed Development
Future levels of service with the proposed development plan were estimated based on the future traffic
volumes shown on Figure 4 and the HCM 6th methodologies for signalized and unsignalized intersections.
The results of these analyses are provided in Attachment II and presented in Table 4 and Table 5.
As shown in Table 4, levels of service under future site development conditions for the Frontage
Road/Greenfields Drive and International Drive/Greenfields Drive intersections are projected to operate at
LOS “A” in the AM and PM peak hours in 2023.
The International Drive/Greenfields Drive intersection is forecasted to operate acceptably as a two-way
STOP controlled intersection as shown herein and within the MTIS. As noted in the MTIS this intersection
is shown on the Master Street Plan as a roundabout. It was likely assumed that such control would be
necessary at the intersection of two arterials. As shown in the MTIS and herein vehicle trips to and from
the eastern approach of this intersection are forecasted to be minor. The volumes shown herein and the
MTIS would not necessitate the need for improvements.
As an additional check regarding the operations of the future International Drive/Greenfields Drive
intersection a Peak Hour signal warrant was performed for 2023 conditions. The Manual on Uniform Traffic
Control Devices 2009 Edition (MUTCD) provides a nine (9) distinct warrants for determining the
