Boston 2024, a private group spearheading the city's bid to host the summer Olympics, unveiled an updated proposal Monday morning. One major change affecting JP would be that a pool is no longer being envisioned for Franklin Park. Looking at the new proposal from a city-wide perspective, the ambitious plan calls for the construction of two entirely new Boston neighborhoods. The proposal, dubbed 2.0, outlined plans for a temporary Olympic stadium that would seat 69,000, and would be completely repurposed or recycled after the games. Adjacent to the stadium, in "Midtown," are plans for 4,000 permanent units of housing, including 500 affordable units.
