I am concerned that a proposed development is using too low a trip generation figure. The project is a high density condo project in steep hills near downtown.
While the project connects to a street with bus service every 15 minutes, the steep terrain, limited visibility curves in the transit street (no stops or other buildings currently in the area), and lack of sidewalks makes me think that transit use will be lower than typical. Based upon the preliminary plans, the walk to the closest safe location for a transit stop is about 800 feet from the closest building and 1150 feet to the furthest, with an elevation change about 100 feet.
All dimensions are scaled from a dwg on normal letter sized paper.
The project has 279 units and 283 parking spaces. While one space per unit is common in relatively similar projects around here, all those projects have good sidewalks, some shopping within easy walking/biking distance, and are closer to transit stops. Except for a half dozen spaces that are time limited for a park (and are supposed to be for park use only), there is no on street parking or other public parking within a quarter mile or more walk.
The steep hills resulted in narrow streets without sidewalks when the streets were built 50-100 years ago.
My questions are below. I may need to convince others that this project’s assumptions are wrong or unrealistic. Please cite sources whenever possible, although I welcome your unsourced replies as well.
1) Given the poor non-auto access outlined above, does the project need more guest parking spaces?
2) The access street for the project has congestion issues, and the project may be scaled back due to other zoning issues. How many new motor vehicle trips per unit or parking space would you expect or use for design and approval purposes?
