Too many parking lots.
The number of parking spaces for parking requirements are most likely too high. Reduce the number of spaces and add covered bike racks.
Parking lots are hot and gross. Abundant parking encourages driving creating more congestion. A majority of trips from the home under 4 miles are done by car, which would take less than a half hour by bike.
I would suggest reducing the amount of required parking spaces for new business and supplementing bike racks and lanes to encourage more use.
