A new development proposal has been submitted for the parking lot next to El Jebel Shrine in Uptown, a site with a history of grandiose proposals that haven’t panned out. The plans, submitted earlier this month, call for a 30-story condominium building to be constructed at 1750 Sherman St., just south of the Shriners’ former temple that dates to 1906. The parking lot has been eyed by multiple developers over the past 20 years, including Donald Trump a decade before he became president.
