In his bestselling memoir, “Trump: The Art of the Deal,” billionaire property developer Donald Trump noted that the best way to generate excitement about a job site is to put some bulldozers, trucks other heavy equipment on the site — to make it look busy.

By The Donald’s gold standard, downtown Butler just became a more exiting place. Heavy equipment has rolled onto the site of the Centre City Project.

Ken Reilly Contracting of Butler began demolition Tuesday of the Sons of Italy building on Main Street. In its place will rise a new and expanded Rite Aid Pharmacy, projected to open in October.

The pharmacy is just a part of Centre City, which will emerge as three constructions rolled into one development. Alongside the new Rite Aid at Main and Cunningham streets, developers will build a three-tier, 225-car parking garage at Cunningham and McKean and an 80-room Marriott Springhill Suites hotel at McKean and Jefferson.

Work on the pharmacy will start in a few weeks. The garage and hotel construction should start by summer and be completed in a year.

Combined, the three constructions represent an $18 million investment in the future of downtown.

Meanwhile, plans continue for another major construction less than a block away — an estimated $12.2 million county government center annex building. Butler County Commissioners intend to award a contract April 30 for the four-story office building, to be built at South Washington Street and Vogley Way, adjacent to the government center. The county anticipates work to begin on the annex this summer and be completed by the summer of 2015.

That means four major construction projects will be under way soon in the downtown. While the commencement of construction generates excitement, we’ll eventually realize the reality that the coming year will bring dust, noise, delay and inconvenience. Construction will take two parking lots out of commission, and the users of a third parking facility, the parking garage at South Washington and Cunningham, may be crowded out at times by construction of the office annex next door.

In other words, the excitement might wear off in a hurry.

But it shouldn’t wear off. We should remain excited by developers’ multimillion-dollar investments represent a deep faith in the future of downtown and an expectation of a return on their investment. We should anticipate a ripple effect as smaller businesses renovate, relocate and increase staff within the central business district.

The renewal of Butler is something to celebrate. We congratulate the developers and construction contractors and wish them well.

And we urge patience for all those who live, work and do business downtown during this period of transformation.
