Dan Armstrong came to the library with a plan for expansion. In an interview, he outlined his plan: “And basically what I'm proposing to the board, and I proposed this during my interview, is (to) isolate $910,000 in our corporate fund that will be used for debt service over the next 20 years. And that will allow us to issue approximately $12 million in debt certificates that will give us money to finance two projects. One will be a 20,000-square-foot branch down at Aspen (Drive) and Route 60 in space we hope that's available there. And the other would be a renovation and expansion of the Cook Park library, adding about 10,000 square feet. Down at Aspen, what I'd like to do there also is ... build 20,000 square feet of unfinished space in the basement, so we'd actually have a 40,000-square-foot building there and a 43,000-square-foot building at Cook Park when we're all done. ... What we'd end up with is two, pretty good-sized library buildings.” Both libraries were to be full-service with possible amenities like coffee shops, open computer labs, and a screened porch at Cook Park.85 In May 2007, the Library Board voted 5-1 to go ahead with the proposition.86
The library board worked with village trustees to move forward with expansion and building proposals in Libertyville and Vernon Hills. The $14 million project includes a $7 million expansion at the main library and a $7 million full-service facility in Vernon Hills.
While preparing for the expansion, the Board discovered that their lease had expired in 1984. The land, owned by the Village of Libertyville, was being leased for $1/year. After the expiration discovery, the Board began drawing up new lease agreements for the next 99 years at $10/year.97
On January 24, 2009, ground was broken at the Aspen Drive site. (see pictures below) 97
On March 10, 2009, the Libertyville Village Board unanimously approved expansion plans.
On March 29, 2009, construction began on the Vernon Hills site.
