Harvard Enterprise Research Campus

Located in Boston, Massachusettes, the 6 acre site serves as the first phase, Phase A of an entire14 acre mixed use development. The campus include research-focused buildings, green space, residential, hotel and a conference center. Focused on the public realm, the site is intersected by a greenway that consists of a variety of accessible spaces. Such includes a bio-classroom, raised lawn bed, central plaza with a water feature, grove of trees with seating. Design elements took into considereration urban

heat island through the implementation of light-colored paving material, tree cover, retention basins and swales to collect stormwater. Highlighting accessibility,a focus on interactive bike lanes, sidewalks and other visible amenities that targets all age groups allows the greenway to connect neighborhoods from the west of the campus to the Charles River. The campus is headed to take ground between 2022 and 2024.

Tom Lee Park - Cutbank Bluff

Located in Memphis, Tennessee, Tom Lee Park stretches 31 acres along the Mississippi River. The park was named in 1954 for Tom Lee, a Memphis hero and Black river worker who saved 32 people from a sinking steamboat in the Mississippi. Tom Lee Park is broken up into four unique zones that serves for outdoor fitness, environmental education, multi-generational play, concerts, private events and many more. The park’s landscape and features are inspired by the geological, ecological and hyrdological flows of the

Mississippi River. The Cutbank Bluff is a newly ADA accessible switchbank ramp entrance that connects downtown Memphis to the park. Color studies of the stone scrambles along the ramp were done to mimic the contrast and texture of the Bluffs of the Mississiopian and Ordovician stratas. Stones for the scrambles were also handpicked at a variety of quarries by the design team during the project phases. The park is scheduled to be fully open to the public spring of 2023.

Baltimore Design Studio - Revitalize the Unutilized

The idea of revitalizing the unutilized focuses on a new approach to activating vacant lots and connecting them with adjacent alley ways to create better spaces for those local and visiting neighborhoods of Baltimore. With an abundance of vacant lots and structures throughout Baltimore, the intent is to be able to encourage those from neighborhoods such as Penn North and Reservoir Hill to take a new look at their environment through the implementation

of ecological and social designs in nearby unused outdoor spaces. The addition of tree canopies and a slight approach to storm-water management aims at studies done by BES (Baltimore Ecosystem Study) that highlights how these features has great benefits in urban areas.

Pittsburgh Strip District Design Studio - Green Node

Plan:

As the Strip District continues to expand with new infrastructure and residents, there comes time to take into consideration of outdoor green spaces that can be a great escape from daily activities. Due to the lack of green spaces in the Strip District, there is room for that opportunity. The design intent of this urban green space is to create a restorative zone where one can connect with a nature while evoking feelings of being in an urban forest with an extensive tree canopy along with rain gardens. This small urban pocket park can serve as a junction for numerous activities as it lays in the heart of the Strip. This space having a mixed amount of informal and formal seating responds

well to the surrounding amenities of the site when it comes to looking for a great outdoor space to enjoy a quick bite of food, catching up with a friend or for some down time. The site also lays a performance space with a backdrop of an interactive mural that can showcase local artist, amphitheater style seating, areas for pop up farmers market and many more.

Community/Public Space Design

Located on North Atherton Street in State College, PA, this vacant site was once a mobile home park. With a plethora of commercial development in the North Atherton area, attention was brought to the master planning of a mixed-used, medium to high density residential local community with consideration of social, environmental and policy context. Transitioning

Phase 1: Master plan

through phases of precedent re-search to analysis, a conceptual design of a master plan was developed and then moved on to a refined detail of a specific area of choice.

Mixed Planting Bed Design

This project consisted of doing a plant palette research with a focus on herbaceous Perennials, selection of a small ornamental tree and shrub species. Along with research came consideration of the hardiness zone of the area, plant forms, texture, height, color and many more factors.

The design layout of this mixed planting bed is focused on giving visitors a striking encounter with the variations of plants with-in the garden. Upon entering visitors get a compressed feeling from large grasses creating tunnel views towards the perennial plantings. After transitioning through the entrance, the feeling of the space becomes loose in which the heights of plants are low towards the main walkway which also gives a feeling of the plants (ferns) gravitating towards you.
