SIGHT DISTANCE STUDY
Capalina Road At APN 219-115-33-00
PROJECT NAME: Capalina Apartments
DATE OF STUDY: April 4, 2023
DATE OF ON-SITE OBSERVATIONS: March 24, 2023
PURPOSE:
This study is to analyze the sight distance situation at the proposed two driveways for the Capalina Apartment project.
METHODS:
This study is following the City’s “Intersection Sight Distance Guidelines (12/2/2020).
STEPS:
1. On-site observations were done at the proposed driveway locations.
2. Photos following the City’s guidelines were taken.
3. Due to the presence of fencing around the property, we were not able to take the photos at 15’ behind the proposed edge of travel way.
4. Photos were taken from the proposed edge of the travel way at the two proposed driveways.
5. Since the project is proposing to widen Capalina Road and that the proposed on-site grading is higher than existing, we combined the proposed & existing surface topography to analyze the sight distance condition at the two new driveways.
6. Plan & profile sections were then generated & analyzed. These analyses were taken from 15’ behind the proposed edge of travel way and at 3.5’ higher than the proposed on-site grading.
7. The results were then tabulated and as follows:
SIGHTING ROD LOCATION 85TH PERCENTILE
