ANDREW G. HATCH stories of connection [water and the urban fabric]
a design portfolio
As a native southern Californian I grew up exploring the varied landscapes of the Southwest and Baja California. The interface of land and sea has held special attention for me as the convergence of the Pacific Ocean and desert landscape evokes a special feeling within me. I have also been lucky enough to travel to varied locations around the world, further forming my sense of place on the Earth. Following my college years, I earned a Master of Science in Real Estate degree with the hope of one day being able to help guide development in a more responsible way, preserving and enhancing critical natural resources while providing structures required to sustain the growing population. The combination of curiosity for design instilled by my grandfather, a prominent San Diego architect, and my desire to improve humans’ interaction with nature led me to discover and explore the field of Landscape Architecture. Exploring the field while earning my Master of Landscape Architecture degree exposed me to the breadth of the profession and cemented the notion that this is what I want to spend my life pursuing. My goal is to earn licensure and build a career focused on the promotion of the unlimited possibilities associated with Landscape Architecture. It is this confluence of life paths which brought me here.

[FUNCTIONAL] an approach to maximize use of remnant urban space
location: Oxnard, California connections explored: community to natural resource to infrastructure applications used: AutoCAD, Photoshop, Illustrator, InDesign, SketchUp
QUESTION How can a single-function infrastructural element and the remnant space in the urban fabric it creates be reimagined as a multi-functional community amenity that connects residents to ecological and recreational assets? This project explores the possibility of re-imagining a section of remnant space adjacent to the Ormond Lagoon Waterway (OLW) and the Ventura County Railroad (VCRR).

FINAL CONCEPT MASTER PLAN The final concept is a refinement of the Broken Pause concept. The design treats the site as two separate zones that interact with visitors in different ways, yet remains connected. The infrastructural pause encourages visitors to pause and reflect on nature around them. The active, recreational portion of the site is connected to the passive, ecological portion of the site by a pedestrian viewing bridge. The ecological side provides ecological services such as runoff infiltration and cleansing, as well as opportunities for habitat establishment through a reintroduction of a coastal sage scrub and alkali riparian planting scheme. This area also serves as a basin to divert potential flooding in the adjacent residential area. The recreational side provides recreation space for all ages as well as social interaction of residents. The porosity of this corridor is enhanced through the removal (or breaking) of sections of the wall separating the residential area from this once underutilized corridor.

FOCUS AREAS In order to naturalize and lengthen the waterway its concrete walls break with sections of naturalized (approximate slope of 1:3) embankments visually suggesting the breaking and slowing of old infrastructural systems. At this point in runoff’s journey the majority is diverted into the three stage constructed wetland, further slowing the runoff, while cleansing and infiltrating it as a gesture to what the area may have looked and functioned like before development. A pedestrian bridge spans over this zone, offering areas for viewing the wetland as well as the distant mountains.

The western part of the site, adjacent to residential development, focuses on providing recreation and play opportunities for residents. Play areas for three age groups occupy the space between the fenced off railroad tracks and the naturalized stream banks. Between the play areas is seating for adults to socialize and watch the children. These areas are physically connected to the OLW by recessed seats/steps that offer opportunities for closer engagement with the waterway. The greenway section parallels the railroad tracks and provides for efficient pedestrian movement through the site while also offering places to rest and observe the surroundings. Oak trees line this corridor and provide shade in the warm summer months. The viewing mound creates a visual and physical transition to the bridge, while simultaneously buffering the train noise that the broken sound wall accomplished previously. This wall is broken, akin to the broken channel wall, in order to create direct access for residents.

URBAN REPOSE creating an urban sactuary on an abandoned railyard
location: Prague, Czech Republic connections explored: landscape to buildings to city applications used: AutoCAD, Photoshop, Illustrator, InDesign, SketchUp partner: Shwan Zhudi [produced architectural plan + renderings] The intent of the original master plan was to create a retention basin thereby directing urban runoff to this constructed wetland. However, there was no response strategy developed against the noise that is created by nearby traffic. The question was raised “Is it possible that this constructed wetlands can be utilized more than just a utilitarian perspective? Can this constructed wetland be a place of leisure and relaxation within Prague 7?� As a result, we proposed a solution that mitigated the nearby traffic noise, and created an area that sharpened and enhanced the newly constructed habitat for people to gather and enjoy. Each of the program spaces are designed to look upon the wetlands.

DESIGN DEVELOPMENT
Urban runnoff is directed toward the newly constructed wetlands. As a result, the collection of water creates the potential for a desirable place for people & wildlife.
Traffic noise will invade the space, making it less desirable for people to stay. The architecture and sculpted mounds enhance the noise abatement strategy.
In order to calm the wetland experience architecture was proposed to mitigate noise. An introverted attitude was introduced towards the street edge, further focusing the site programming inward.
design intent: create Monet paradise within gritty urban fabric

SONORAN RESILIENCE bringing the desert back to the desert
location: University of Arizona, Tucson connections explored: water to site to users to desert applications used: AutoCAD, Photoshop, Illustrator, InDesign, SketchUp partner: Lee Eubank [produced renderings on top right of page 22] award: 2015/16 College of Architecture, Planning, and Landscape Architecture Design Excellence The design, at the Universityâ&#x20AC;&#x2122;s Science Concourse, proposes a solution for stormwater management that is scalable, resilient, and modular. The site is 5.5 acres of disconnected parking lots, paths, gathering spaces, bare soil, and well maintained desert garden beds. It serves as a major pedestrian corridor for students and faculty to access the campus from surrounding student housing and parking lots. The Concourse is bounded to the west and north by a 100 year flood plain that is prone to seasonal flooding; runoff from the site contributes to this flooding problem.
goal Create an ecologically resilient, functional, and inviting campus site that combines an integrated water management system with a desert oasis experience based on the form and adaptation of the Saguaro (Carnegiea gigantea) cactus.
objectives 1. Manage runoff through a decentralized system that infiltrates, filters, and detains stormwater 2. Enhance the performance and health of Sonoran Desert urban area 3. Create pleasant urban experience for users

Ideas and Application: The repeated pattern of the cactus form creates opportunities to convey, slow, and store stormwater; create distinct spaces and microclimates of sun/shade, wet/dry areas, and high/low elevation. Variation of cactus species creates distinct and multi-functional spaces for users.
ing
Design Insights: Cacti exemplify the ability to expand and contract in reaction to drought and the intense monsoonal rains of the Sonoran Desert. This gesture of resiliency has enabled them to thrive in this extreme environment for millennia.
