Just like there is a Paris, TX, and a Dublin, CA, as of Dec. 2011, there is a new Walnut Creek on the East Coast, specifically located in South Carolina. From their website:
Walnut Creek is convenient to everything—shopping, employment, entertainment and recreation. Ballantyne and the I-485 interchange are just 20 minutes from the community. Uptown Charlotte is only 25 miles north.
Walnut Creek offers quality housing in an affordable and stable neighborhood amid the historic and natural beauty of Twelve Mile Creek. For those seeking an active lifestyle, amenities include the Creek itself and the adjacent 60-acre Walnut Creek County Park.
Located in one of the fastest growing counties in South Carolina, the area around Walnut Creek has excellent shopping. Within three miles of the community are two Harris Teeter grocery stores, Lowes Home Improvement, several banks and a Starbucks. A new Publix grocery store is under construction four miles from Walnut Creek.
Welcome to all the new residents of Walnut Creek, SC.
