I am very concerned that there is insufficient vehicle access for the proposed population of the development. The entrance on 500 West is on a sloping curve with limited visibility. 300 cars trying to exit the property each morning through that one bottleneck will be a nightmare. The residents' other option will be to exit via 730 West. That will send them into a quiet residential neighborhood where small children play in open front yards. 730 is NOT designed to support morning and afternoon rush hour traffic. There will need to be stop signs, perhaps speed reduction pads, etc. The only reasonable alternative is to find a way to let people enter and exit via Lakeview Parkway somehow. That gets people into the traffic flow without turning a residential neighborhood into an on-ramp.
Given the access limitations, I believe the zoning should be single family residential, similar to the adjacent Osprey Point subdivision to the north. The developer should still be able to realize a tidy profit and the development would impose less of a burden on infrastructure. Access is not the only problem in that area. Sewer, schools and other infrastructure elements are at or above capacity.
