WP0202300012 - Birdwood Mansion Rehabilitation -- Engineering review comments [
Initial ]
Hi, Maria,
As I reviewed plan documents received 2/24/23, since comments were relatively few, I thought to send comments in this

I intend to send follow-up with same comments in Memo format with process steps, for once the plan is approved.
I should be able to send the memo, tomorrow. Thanks for your help and patience, best, J. Anderson
