Lacey sported one of the Northwest's first ever "indoor malls," South Sound Center. It has since been partially demolished and turned into an outdoor shopping center. When the Lacey Plywood Mill shut down, Lacey took on the challenges of being a place to invest in. Lacey now flourishes with retail, warehousing/distribution centers, a large retirement community, a major mushroom farm, and Weyerhaeuser's corrugated container facility. Lacey is also experiencing a building boom mostly on its northern border. The area around Hawks Prairie has exploded with commercial and residential building. This is also the site of a planned "commercial" core and high-rise district. The "Gateway Project" started in October 2007, when the major Sports & Outdoor store Cabela's was built in the Hawks Prairie District. Soon, many other high rise buildings will be built around Cabela's and Lacey may have a big population boom that would make it one of the largest cities in all of Washington. NFL Washington Redskins Fullback Mike Sellers plans to build a Multi-Sport/Event Center, or a Football Dome in Hawks Prarie, which would attract National competitions, (i.e, football, baseball tournaments, concerts, other various events.) Lacey is also in the top 7 most "Green" cities in all of America. And has been noticed by the nation as an Energy Efficient City. Lacey is also nicknamed, Tree City, USA. Hundreds of thousands of trees line the streets of Lacey, and with various lakes and parks, Lacey is the one of the most beautiful cities in all of America.
