Document 2: Parkridge, Saskatoon: Parkridge is a residential community in western Saskatoon, Saskatchewan, located on land annexed by the city between 1975 and 1979. Development of the subdivision (initially called "Fairhaven II" after the neighbouring community to the east, began in the early 1980s. The extreme west end of the neighbourhood remained undeveloped until the subsequent creation of the adjacent Blairmore Suburban Centre led to the final phase of Parkridge being built out in the early 2010s. Whereas the majority of residents are employed in the sales and service sector, the next highest employer is business, finance and administration. The two main age groups are those in their 40s and teenagers as of 2005. Until recently Parkridge was the farthest western neighbourhood of Saskatoon south of 22nd Street.

Document 12: Sharp Mountain Preserve, Georgia: The Preserve at Sharp Mountain (also called The Sharp Mountain Preserve) is a nature-based community located near Jasper, Georgia in Pickens County. It is one of three mountain communities in Pickens County, and the only one dedicated to maintaining its natural amenities. There are 12 mi of paved roads running through the community, but the population density is intentionally low (approximately 300 lots over 1600 acre ranging in size from a minimum of 3 acre to a maximum of 37 acres.) The Preserve at Sharp Mountain was named the "Best Community for Outdoor Lovers" by Pinnacle Living magazine, Unlike many planned communities, the Preserve at Sharp Mountain does not have swimming pools and tennis courts with club houses or golf courses. Instead, the Preserve at Sharp Mountain offers many acres of green space, hiking and nature trails, a nature pavilion, waterfalls, a bird sanctuary, a butterfly garden and various nature parks. The community is gated to restrict use of its 12 mi of privately owned roads to those living in the community. The Preserve at Sharp Mountain was developed by Four Seasons originally, which later became Naterra Land. Naterra's stated goal in all of its projects is "to better connect people with nature." Naterra Land sold out all of its inventory in the Preserve, and control of the community is now governed by a Property Owners' Association (POA). In 2011, the Preserve Association switched from being an HOA (Home Owners' Association) to being a POA (Property Owners' Association), each being viewed differently under Georgia law. In 2008 the Preserve became a recognized member of the national Firewise communities program and is one of the 13 in Georgia.

Document 14: St. John, Florida: St.John and Robertsville are two unincorporated communities in Gadsden County, Florida, United States. They are located near the intersection of Old Philadelphia Road and Old Bainbridge Road. Unlike some people think, the communities are not a part of the Mount Pleasant area. They recently had a zipcode change which split the community into two zipcodes, however the community considers itself a part of Quincy. They are approximately 5 miles outside of the city limits of Quincy, Florida. St. John borders the city of Gretna and the Robertsville community borders the Georgia state line, Attapugus, Georgia, Faceville, Georgia and Chattahoochee, Florida. These two communities are usually spoken of and thought of together although they are separate and distinct. St.John is known for its school, St.John's elementary school, the St.John/Robertsville park, the St.John volunteer fire department and most recently the St.John Church of God in Christ. The church has been a staple in the community for over 50 years but is noted because of its new building on Old Philadelphia highway. The church was featured in the local newspaper The Gadsden County Times, because of its expansion. The church was also granted St. John Church of God in Christ day in May 2010 by then commission chair Angela Sapp. The church has launched many Christian leaders over the years, such as Nicky Yarborough These achievements have made St.John Church of God In Christ #86 among the top 1000 black (African-American) churches. Other churches in the area include the St. John AME church. It is also known for the McCloud’s Assisted Living Facility, which was the oldest assisted living facility in Quincy, Florida until it closed in 2006 due to health concerns of the administrator. The community is proud of its growth and achievements. St. John shares its facilities with Robertsville (its closest neighbor) and other communities in Gadsden County. It also borders the city of Gretna, Florida. The communities associate themselves with the city of Quincy as their city.
Document 15: Midtown Walmart: Midtown Walmart is a controversial proposal by Walmart to build a 203000 sqft supercenter location on a 4.6 acre site in the planned sub-district of Midtown in the city of Miami, Florida, USA. The initial proposal did not meet local regulations and was rejected in February 2013, but was redesigned by Gensler and approved by the city commission in August 2013. It has faced public and political opposition from area residents, business owners, and community activists even as it has been adapted to meet strict zoning regulations that resulted in the design differing greatly from the typical layout, such as utilizing second story roof parking versus a surface lot and street liner retail instead of a blank wall perimeter. The original 2012 plan included 10500 sqft of retail and about 550 parking spaces on two levels above the 184000 sqft store. This more urban footprint is similar to what Walmart did to build a location in Santurce, (downtown) San Juan, Puerto Rico, known as "Plaza 18", as well as Washington, D.C. where the city's first Walmart is a true mixed-use development, with third party retail as well as 300 apartments above the store. Purchased in January 2014 for US$8.2 million, the currently vacant site sits at the southern tip of Midtown between North Miami Avenue and Midtown Boulevard from Northeast 29th and 31st Streets, between the burgeoning neighborhoods of Wynwood and Edgewater. It would be the first traditional Walmart location within the actual City of Miami limits, although there are several locations just outside city limits in Doral, Hialeah, Gladeview, North Miami Beach, and Westchester, as well as a "Neighborhood Market" in the western fringes of the city. In January 2016, Fort Lauderdale opened its first Walmart. After more than a year of litigation, Walmart won a court battle in August 2015. Specifically the litigation targeted the proposed zoning variance for two extra loading berths and traffic congestion caused by the development. Ridership at the Northside Metrorail station increased significantly after the adjacent Gladeview location opened. Other criticism is due to the fabric of the neighborhood amid an urban revival that included small, locally owned businesses and warehouse renovation versus new construction. However, the Midtown development already contains a Target and a Ross.
