The UDRP is a voluntary board of industry professionals, who critique/provide advice on certain projects. However, they are not an approving authority, so their comments do not NEED to be addressed. However, in the last few years, we have seen members of the Planning Commission, who IS the development authority that needs to be listened to, asking more and more to see UDRP comments addressed. Baby steps.
But, it is still frustrating when UDRP sees the early stages of a project, gives advice, etc... Then, as the project goes along, changes are made, even at times after the DP has been approved (and even CPC had their say). A good example is the BMO Expansion, when UDRP saw it, it had a small retail booth at the end of the sweeping roof. Was told it would be a possible active use to help activate the park that was being built. Now, that booth has been removed, it is just the end of a column there. Not sure if that revision was brought back to UDRP, or the builder just did it, and it got the rubber stamp through a revised plan at The City.
