1.0 BACKGROUND Like cities throughout America, Charleston has metamorphosed from a small peninsula city separated by two great waterways, Cooper and Ashley Rivers, from outlying areas, to a regional urban center and economic hub with many of the attendant development patterns that characterizes many of the nation’s urban regions.
The settlement of Charles Towne was founded in 1670. Development of the city since that time can be characterized by three major epochs: Pre- Civil War, Post-Civil War and Americanization, then and now. It is the later metamorphoses that will interest this studio. As a peninsula city, urban development was constrained by water boundaries in addition to defensive, social, cultural and political forces. The city grew into a major economic power during the Colonial and Pre-Civil War periods resulting in an extraordinary urban topological form that has largely retained this historic structure | fabric to this day. However, outlying areas such as West Ashley and James Island developed as suburban typologies in the 50’, 60’s and 70’s replete with early subdivisions, strip commercial, malls, car dealerships and major roadways.
However today, even these development typologies have become dated and the spoils of an auto-focused model has come to be recognized as counter to more urban-centric models. The vagaries of suburban sprawl and commercial strips are now understood to be largely anathema to healthy livable environments. A comprehensive planning study of West Ashley suburb is underway by Dover Kohl, a Florida-based planning firm. Results of their planning work will be formally introduced to the community in early fall. A number of major initiatives are expected to come out of this study that is hoped to transform or re-make development patterns in and about the West Ashley district.
Of particular interest to Studio U is a key site, affectionately known as the “Pig Site”, that forms a “gateway” to West Ashley. The site is located at the confluence of Old Towne Road, Sam Rittenberg Blvd., and nearby Sumar Street. Formerly a Piggly Wiggly grocery store, the site was acquired by the city for redevelopment in support of the West Ashley Plan initiative for a major “Gateway” opportunity. Our charge will be to examine various urban design options for the site concluding with development of an architectural proposal for a civic use at the site. This particular site is important as it is a natural “gateway” to West Ashley from I-26. The study site is contiguous with a 60’s shopping center that is undergoing some renovation. A grocery formally occupied the site but closed and the site has not been redeveloped. Initial attempts to purchase and redevelop the site as a gas station met with considerable community opposition. The city eventually purchased the site with the intention of developing it in the public interest.
During West Ashley planning meetings with the community, a range of possible uses were suggested. We’ll explore some of the proposed uses but our intent is to develop the site as a “civic” use.
The studio will undertake a comprehensive assessment and develop conceptual proposal(s) for the target site to determine the following: ++ Current issues and liabilities of the site ++ Opportunities for redevelopment of the site based on community input ++ Develop architectural proposals for a civic re-use 1INTRODUCTION TO WEST ASHLEY PLAN / STUDIO CHARGE 5 From Dover Kohl Partners draft “Plan West Ashley”: 1WESTINTRODUCTION ASHLEY PLAN TO WEST ASHLEY PLAN / STUDIO CHARGE 6 From Dover Kohl Partners draft “Plan West Ashley”: “A primary purpose of the Plan for West Ashley is to direct the growth and maximize prosperity and other benefits while minimizing the negative im- pacts of any remaining future development.”
West Ashley should strive to reflect the very best balance of livability, effi- ciency, environmental stewardship, sensible transportation, prudent regula- tion, and private property rights. DRAFT PLAN WEST ASHLEY PLAN WEST ASHLEY

Phase 2 - Development of Piggly Wiggly Site: Prepare a series of conceptual strategies for a new civic performance ven- ue on the Piggly Wiggly site. 2West Ashley Plan Objectives 2WEST ASHLEY PLAN OBJECTIVES 10 Urbanizing a Suburban Typology “West Ashley’s community character and identity is weakened by vacant strip malls, generic and aging shopping centers, and lack of identity at en- tryways.” SUBURBAN Condition: • Lack of connectivity • High void to solid • Auto focused • Disconnection • Light density • Too few "centers" • Disassociations • Displacement

URBAN Condition: • Interconnectivity • High solid to void • Multi-modal • Higher density • Series of "centers" • Scaled • Pedestrian
Downtown Charleston 2WEST ASHLEY PLAN OBJECTIVES 11 Regional Focus Areas Vision is to make strategic interventions in focused areas • Focus on commercial corridors suitable for future development • Vision identifies where changes to achieve these objectives can be fo- cused
“There is an opportunity for the West Ashley Plan vision to guide interventions in an focus area.”
Source: Plan West Ashley (draft - 12/5/17) 2WEST ASHLEY PLAN OBJECTIVES 12 Regional Focus Areas “Areas highlighted in orange and blue below are designated for pri- ority focus using “grow” and “adapt”scenarios due to their elevation, proximity to transportation connections, and environmental suitabili- ty.”
“The adoption of design standards, particularly for sites at West Ashley’s entryways, can also enhance community identity. The urban design of these critical, highly-visible, potentially iconic par- cels will set the tone for the rest of West Ashley.”
“Place specific regulations should be established in priority areas for growth and/or preservation, so all the buildings belong togeth- er in an ensemble, while still allowing for creative architectural expression and variety.” 3Site Issues / Objectives / Strategies 3SITE ASSESSMENTS / OPPORTUNITIES/ STRATEGIES 14 Studio Focus Area at Northernmost Access to West Ashley

North 3SITE ASSESSMENTS / OPPORTUNITIES/ STRATEGIES 16 Target Area Site: Former Piggly Wiggly Site
North 3SITE ISSUES / OPPORTUNITIES/ STRATEGIES 17 Study Site Area Issues • Typical suburban site issues ++ West Ashley developed as a suburban typology typical America settlement patterns with associated issues of that typology
• Lack of urban identity ++ Poor pedestrian options; buildings don’t reinforce public realm; buildings as “objects in a field” most prevalent; lack of hierarchy; poorly defined public realm
• Poor Gateway ++ Confluence of major roadways present significant oppor- tunity for a gateway experience to “enter” the West Ashley district
• Disconnected ++ Study area separated from adjacencies making access other than by auto difficult; commercial uses are not “neighborhood centric”; existing building do attempt to relate to context other than commercial uses
• Poor existing site utilization ++ Surface parking relationship to building massing partial to auto-centric mix; less dense; uses spread out over site 3SITE ISSUES / OPPORTUNITIES/ STRATEGIES 18 Site Area and Target Site Issues • Site scale ++ Poor density exasperated by surface parking located in forefront of building development
• Site form ++ Study area site is triangular bounded by arterials making access difficult; challenges to make cohesive urban build- ing forms
• “Suicide merge” condition at North end ++ Dover Kohl study proposes workable strategies for remedy- ing this challenge
• Subject to future flooding ++ Despite site area base elevation being above minimal flood-prone levels,, future considerations of elevating water levels need to be considered 3SITE ISSUES / OPPORTUNITIES/ STRATEGIES 19 Site Context • Site contiguous with residential development at western end • Eastern portion of site adjacent to strip commercial
North 3SITE ISSUES / OPPORTUNITIES/ STRATEGIES 20 Disassociated Site • Two high-speed, high volume roadways isolates Focus Area • Creates an “island affect”
North 3SITE ISSUES / OPPORTUNITIES/ STRATEGIES 21 Site Utilization and Urban Wall Relationship of parking to building poor. Minimum building edge at roadways fails to create an urban wall. Typical of suburban commer- cial strip development.
North 3SITE ISSUES / OPPORTUNITIES/ STRATEGIES 22 Site Access • Vehicular: Multiple access disorganized and non-hierarchical • Pedestrian: Street crossing sans Charlestowne pedestrian unsafe
North 3SITE ISSUES / OPPORTUNITIES/ STRATEGIES 23 Contiguous Commercial • Eastern end of Target Site contiguous with existing commercial • Explore opportunity for linking pedestrian access at key locations
North 3SITE ISSUES / OPPORTUNITIES/ STRATEGIES 24 Flooding Trend • Site is situated just outside the flood zone • Increased rainfall or higher sea levels expected
