What this outcome means
The FAA studied the proposal and concluded it would not be a hazard to air navigation. A no-hazard determination is not permanent — it carries an expiration date, and if the structure is not built by then the case has to be re-filed.
The proposal, in the filer's words
"Resubmittal of Expired ASNs and ASNs that have changed locations. The project has 1935 total residential units 1224 single family (SF) detached homes (45 ft); 176 townhomes (55 ft) and 535 condominiums (100 ft).

Check Part 77 and the tower's line of sight before you file
LOS Analyzer screens a proposed structure against FAA Part 77 surfaces and the control tower's sightline to the runway, terrain-aware, in minutes. It is a preliminary screening — not an FAA determination and not a substitute for a licensed engineering review.
