Grace Foley- LFUCG Traffic Engineering

1. Timeline
a. June/2021- application was submitted
b. Fall/2021 counts conducted
c. May/2022- analysis completed
d. August/2022- manual counts completed
e. October/2022- analysis and information sent to GRI
f. Jan/2023- a review meeting was held with GRI

2. To qualify a road must meet the following requirements:
a. 1000 cars a day or
b. 100 cars an hour or
c. 750 cars per day with at least 25% speeding and 10% speeding 10mph or more over.
d. Winchester to Marquesas had a peak hour of 124
e. Bahama to Cayman had a peak hour of 116

3. We would need 26 speed tables spaced at 500 feet around Bahama so this idea was not pursued- property owns carry bulk of cost

4. NTMP signs will be installed at no cost

5. Edge Lines will be applied to roads at no cost- edge lines reduce speeds 5-7mph and move traffic to the center of the road
a. Parking restrictions between Bahama/Bahama and Bahama/Cayman will need to be changed by petition and therefore those edge lines cannot be completed until the petition is completed
i. Will need 51% of resident to sign petition
ii. Edge Lines would be 8ft on sidewalk side, 10ft double yellow line 10 ft and then 2ft or more on non sidewalk side (any area with less than 7ft will then have a no parking sign)
b. Winchester to Briercroft will have Edge lines spaced 8ft, 10ft double yellow line 10 ft, 8 ft
c. 2138 Bahama to Antilles 8ft, 10ft double yellow line 10ft, 8ft
d. There will be no changes to edge lines by the golf cart crossings because if changes are made in those areas, then the golf cart crossings would have to be removed to bring the edge lines up to current requirements

6. Stop bars will be included at all stop signs

7. Questions from GRI
a. What about using chicanes or chokers?
i. Cost is 3-4x speed tables
b. Discussion regarding bulk of problem drivers being from outside GB
i. Years ago a gate was discussed but cannot be added at Cayman due to fire code restrictions
c. Addition of speed readers?
i. When installed, speeding increases
d. Comment- in 10 years there have been 3 reported accidents inside the neighborhood- 1 was an injury accident
e. Could Walnut Grove Lane be widened?
i. Not the purview of Ms. Foley’s office
f. Could we add edge lines on Cayman Lane?
i. Another application would need to be submitted
