This sort of quid pro quo on infrastructure funding is not uncommon and big developers are familiar with it as a concept. The city where I live made re-development of an old railyard contingent on funding a new bridge over the tracks that were still active. It worked out great for everyone; now there's a nice new neighborhood and fewer accidents on the new bridge, which is wider and straighter.
