Dear Planning Department,
See attached driveway study. A few things to note:
1. See 106 Challenge Court Driveway Study prepared by Kimley Horn. The study demonstrates that 104 Challenge Court can continue to access their driveway with the proposed addition. A portion of the driveway will remain for continued use by 104 Challenge Court.
2. The existing portion of the driveway to remain will continue to be maintained as it has been historically, with each homeowner maintain the portion of the driveway that is on their property.
3. This is for a large vehicle. It’s a standard template used for these types of applications, but want to note that most cars are smaller and more maneuverable. The vehicle studied is 19’ long, so about the length of a Chevy Suburban. The neighbors had a Lexus RX, which is closer to 16’ in length.

Dear Planning Department,
Please see attached driveway study and notes below.
Driveway:
1. The vehicles are able to access both garages and informal parking on driveway fronting the garage. Updated vehicle turning studies are included.
2. RVs would not have been able to parking on the driveway given they wouldn’t fit outside of the shared parking area, and there isn’t need for access to side or rear of yard given there isn’t sufficient space for vehicle storage. The turning studies are based on having two Toyota Siennas (2023) which are both large vehicles. While it is unlikely one residence would have two of these vehicles, it was meant to be conservative for analysis purposes.
• Engineering:
1. Actual turning radius shown based on vehicle templates created in Autoturn software.
2. Roof projection is 10 feet 6 inches clear from grade. Typical passenger vehicles are typically less than 6 feet 4 inches in height, and most are much shorter.
3. Bollards to be considered, as well as other physical deterrents such as curbs, and planter boxes. To be coordinated with final design.
4. There is no current easement. Homeowner endeavors to obtain formal approval from neighbor and will provide documentation to extent practical.
