스프링데일 그린: 도시 생물다양성의 재탄생  dwg-Springdale Green: Urban Biodiversity Renewed

스프링데일 그린은 12헥타르(약 30에이커) 규모의 정화된 브라운필드가 생명력 넘치는 생태 업무 캠퍼스로 변모한 획기적 사례다. 침습종이 뒤덮고 반복적인 국지 홍수로 황폐해진 이 땅은 이제 생물다양성이 회복된 도시 경관으로, 캠퍼스 용도를 자연스럽게 엮어내면서도 환경 건강과 인간 웰빙을 최우선으로 삼는다.

황폐에서 재생으로: 생태 복원의 여정
급속히 재생 중인 오스틴 중심부 동쪽에 위치한 이 부지는 수십 년간 방치되어 있었다. 침습종이 무성하게 자란 원래 대지에는 낡은 건물들과 고도로 인공화되고 직선화된 도시 하천이 있었는데, 100년 빈도 범람원이 부지의 거의 75%를 덮고 있었다. 이는 설계팀이 한 세대에 한 번 있을 이 복합 부지의 재상상을 개발하는 데 있어 매우 복잡한 과제들을 제시했다.

전환은 부지의 자생 동식물을 질식시키던 수 헥타르의 침습종 제거 및 완화로 시작되었다. 이 노력에 이어 SITES 원칙이 안내하는 단계적 생태 복원 과정이 시작되었으며, 식생 및 토양 보호 구역(VSPZs)이 공사 중 민감한 식생을 보호했다. 부지는 자생 블랙랜드 프레리와 하천변 삼림 생태계로 재구축되었으며, 6헥타르의 자생종 파종, 75,000그루의 식물, 4,000그루의 새 나무가 심어졌다. 두 그루의 수령 수백 년 된 유산 참나무는 이식되어 경관의 핵심 기준점을 보존했다. 도시 생물다양성을 지원하기 위해 120개의 조류 둥지 상자, 화분매개자 초지, 자생 벌집이 도입되어 다양한 서식지를 조성했다.

물과 생명의 순환: 혁신적 그린 인프라
모든 건물이 범람원 밖에 배치되면서, 스프링데일 그린의 그린 인프라는 부지 내부와 기존 인근 지역의 홍수 위험을 100% 완화하는 동시에 자연 수문을 복원한다. 생태여과지, 빗물정원, 침수 가능한 초지가 유출수를 관리하며, 246만 리터 용량의 저수조가 빗물과 공조 응축수를 포집하여 부지의 관개 수요 100%를 충당하고 식수 사용을 제거한다. 부지의 거의 70%가 빗물을 적극적으로 여과하고 매년 45톤 이상의 이산화탄소를 격리한다.

이러한 생태적 기반 위에 펼쳐진 공간은 단순한 기반시설을 넘어선다. 복원된 하천이 부지를 가로지르고, 초지가 계절에 따라 물을 머금었다 내보낸다. 이 순환 속에서 토착 식물들이 뿌리를 내리고, 새들이 돌아왔으며, 벌들이 꽃가루를 옮긴다. 생명의 그물망이 다시 짜이고 있다.

자연 속 인간 공간: 경험과 웰빙의 통합
1킬로미터에 달하는 보드워크가 거주자들을 복원된 경관 속으로 몰입시키며, 생태적 민감성을 유지하면서 참여를 높인다. 웰니스를 위해 설계된 이 부지에는 요가 데크, 숲속 파빌리온, 조류 관찰 블라인드, 소셜 해먹이 있으며, 4,000제곱미터 이상의 옥상정원이 생태적 범위를 사무 공간까지 확장한다.

스프링데일 그린은 텍사스에서 SITES 골드 인증을 획득한 최초의 캠퍼스이며, LEED 골드 및 Fitwel 인증도 진행 중으로 지속가능성에 대한 헌신을 확인한다. 다크스카이 준수 조명은 빛공해를 줄이고, 지속가능한 재료 사용은 환경 영향을 최소화한다. 브라운필드 부지를 재상상된 업무 캠퍼스이자 기능하는 생태 자산으로 재활용함으로써, 스프링데일 그린은 도시 회복력과 재생 설계의 선례를 제시한다.

스프링데일 그린은 조경 건축이 환경 악화를 역전시킬 수 있음을 입증한다. 한때 활용되지 못하고 간과되었던 이 부지는 이제 수천 명의 거주자를 살아 숨 쉬는 생태 보호구역과 교감하도록 초대하며, 도시 지속가능성을 재정의한다.

Springdale Green is a groundbreaking transformation of a 30 acre remediated brownfield into a thriving ecological workplace campus. The property was subject to regular localized flooding and was over-run with invasive species that resulted in an ecologically barren landscape. Through a highly innovative design process, it is now a biodiverse, resilient urban landscape, seamlessly integrating a campus use while prioritizing environmental health and human well-being.

Historical Context and Site Transformation 
Located in the heart of a rapidly regenerating Central East Austin the 30ac remediated Brownfield site had remained underutilized for decades.  Overgrown with invasive species, the original site had a collection of old buildings and a highly engineered and channelized urban creek with a 100yr floodplain that covered almost 75% of the property.  These presented a host of highly complex challenges for the design team to develop a once-in-a generation reimagination of this complex site.

The transformation began with the mitigation and removal of acres of invasive species that were choking the site’s natural fauna and flora. Following this effort a phased ecological restoration process was launched, guided by SITES principles, with Vegetative and Soil Protection Zones (VSPZs) safeguarding sensitive vegetation during construction.

Ecological Restoration & Biodiversity 
The site was reestablished as a native Blackland Prairie and Riparian Woodland ecosystem, with 15 acres of native seeding, 75,000 plants, and 4,000 new trees. Two centuries old heritage live oaks were relocated, preserving key anchors of the landscape. To support urban biodiversity, 120 bird boxes, pollinator meadows, and native beehives were introduced, fostering a diverse habitat.

Innovative Stormwater & Water Management 
With all buildings being located outside of the floodplain, Springdale Green’s green infrastructure mitigates 100% of on-site and off-site pre existing neighborhood flooding risks while restoring natural hydrology. Biofiltration basins, raingardens, and floodable meadows help manage runoff, while a 650,000-gallon cistern captures rainwater and HVAC condensate, covering 100% of the site’s irrigation needs and eliminating potable water use. Nearly 70% of the site actively filters stormwater and sequesters over 45 tons of CO2 each year.

Human-Centered Design & Connectivity 
A one kilometer boardwalk immerses occupants in the restored landscape, enhancing engagement while maintaining ecological sensitivity. Designed for wellness, the site features a yoga deck, woodland pavilion, bird blind, and social hammocks, along with over an acre of rooftop gardens, extending the ecological footprint to office spaces.

Sustainability & Resilience Impact 
Springdale Green is the first campus in Texas to achieve SITES Gold and is also on track for LEED Gold and Fitwel certifications, confirming its commitment to sustainability. Dark sky compliant lighting reduces light pollution, while sustainable material use ensures minimal environmental impact. By repurposing a Brownfield site into a reimagined workplace Campus and a functioning ecological asset, Springdale Green sets a precedent for urban resilience and regenerative design.

Springdale Green demonstrates that landscape architecture can reverse environmental degradation. Once underutilized and overlooked, the site now invites thousands of occupants to engage with a living, breathing ecological sanctuary, redefining urban sustainability.
