More than 15 years after first seeking to build Orange County's tallest building in Santa Ana, developer Mike Harrah is tweaking his plans.

Harrah's development, called One Broadway Plaza, is slated for a currently vacant property at the corner of 10th Street and Broadway.  Since first proposed in 2004, plans have called for the construction of a 37-story tower featuring approximately 518,000 square feet of offices.

Now, according to a pending staff report to the Santa Ana Planning Commission, Harrah intends to tweak the mix of uses within the project.  Plans now call for the construction of 415 apartments - including studio, one-, two-, and three-bedroom dwellings - within 19 floors of the building.  The remaining floors would contain no less than 200,000 square feet of offices.

Plans also call for a freestanding nine-story parking structure which would contain 2,463 vehicle stalls and ground-floor restaurant space.

A staff report recommends that the City of Santa Ana should approve requested entitlements for the project.

Harrah, through his company Caribou Industries, has proposed several large mixed-use projects in the City of Santa Ana.
