Hundreds of people showed up for the South Placer Business Walk held Sept. 30. Business walks are part of a regional “best practices” strategy for business retention and expansion. Last week, business and civic leaders visited more than 1,000 businesses during the Business Walk. Participants visited businesses of all kinds — retail, office, industrial, commercial — and asked three questions: How’s business? What do you like about doing business here and what needs to be improved? What they heard immediately gets to economic development staff that can help with issues that arise. The day began at William Jessup University and the wrap-up session was held at Thunder Valley Casino in Lincoln.
