In the coming decades, rising sea levels will pose a serious threat to the integrity and vitality of the Bayside neighborhood. To protect Bayside, it will be necessary to either raise a substan al por on of the neighborhood or to separate Back Cove from the dal effects of the Atlan c Ocean. Our concept proposes severing the cove from the ocean by means of a dam, which would stabilize water levels and allow Bayside to con nue to grow. The Back Cove becomes Back Cove Pond, hydrologically an isolated stormwater management resource that is no longer subject to dal fluctua on. Back Cove Pond will offer new opportuni es for waterfront development and recrea on, as well as enhanced transporta on connec ons and a rich new ecological regime. New development on the shores of the pond, in combinaon with the planned transforma on of I-295 from highway to boulevard, will create vibrant, mixed-use neighborhood growth centers. With ample new recrea on space along the water, Bayside will become a neighborhood of waterfront parkland, fully connected to exis ng parks, including nearby Payson and Deering Oaks. An integrated network of new pedestrian and cycling routes will connect the neighborhood to the rest of the City. Finally, the pond will serve vital ecological func ons, collec ng and naturally trea ng stormwater from the surrounding urban watershed, providing habitat, and suppor ng a diversity of species within the City. Our climate change scenario assumes up to 10’ of sea level rise over 80 to 100 years.

BACK TO MILL: UNEARTHING PORTLAND’S EMERALD NECKLACE ACETO LANDSCAPE ARCHITECTS
BACK TO MILL: UNEARTHING PORTLAND’S EMERALD NECKLACE Back to Mill is a study of the city as a super-organism in the context defined by intertwined factors influencing the built environment. These factors include climate change (sea level rise) population growth, transportation, consumption and emissions, and socio-economic considerations. Back to Mills concept focuses on returning the sea (Back Cove) to the currently buried Mill Cove, allowing natural systems to help mitigate storm surge while providing an impetus for sustainable redevelopment in the Bayside District.

THE SURGE: Rapidly rising sea level combined with strengthened storm surge and a glut of impervious paved surfaces and other manmade interventions lead to widespread flooding and property damage across the Bayside district.
THE RETREAT: Perpetually inundated infrastructure and property damage force the Bayside community to come to terms with rising sea level. The first step to a sustainable Bayside is unshackling natural systems. Here, the historic Mill Cove is unearthed from Interstate 295, and roads are re-aligned to accommodate the flooding.
RECONNECT: A sea wall and berming is introduced along the newly re-aligned Bayside Parkway. The local street grid is reconstituted to historic alignments and reconfigured with pervious paving bio-detention swales and gardens to help mitigate localized flood risk. Mill cove expands, reconnected with the Deering Oaks waterway.
PROTECT: The fully integrated sea wall allows for full redevelopment of the Bayside district, creating a network of walkable streets, tightknit neighborhoods. Dense, mixed-use blocks encourage walking and transit, contributing drastically to overall reduction in global carbon emissions.

BACK COVE
MILL POND In 1851, Portland’s shoreline reached approx what is today known as Kennebec Street. Today, we can still see the historic railroad alignment defined on each side by brick-clad industrial-era buildings. Mill Pond was a natural estuary of Back Cove, forming a neck to the north and connecting the cove with then newly designed and constructed Deering Oaks Park. Deering Oaks Park was designed by Landscape Architect Frederick Law Olmsted, designer of Central Park in New York City. Olmsted’s original vision saw a pond that filled with the tide. In essence, Olmsted’s park was a very early example of green infrastructure, allowing stormwater to filter from the surrounding city streets to the bay through a series of estuarine pools and conveyances.

MILL COVE NATURAL AREA: In the future, Portland may choose to re-route I-295 and the associated ramps in order to unearth the cove and connect both the waterway and parks system just as has been achieved in Boston with Olmsted’s Emerald Necklace. Opening up Mill cove would allow visitors to circumnavigate the greater portion of the Portland peninsula via parks ans trails. The added open space could help mitigate rising flood waters as well as treat and slow runoff from the city before passing back to the ocean, thereby reducing demand on costly infrastructure while providing a delightful public amenity.

BACK COVE
On the cusp of the 22nd century, Bayside has adapted to global climate change. A resilient Bayside continues the New England tradition of walkable urbanism, streets designed for a slower pace, and sensible infrastructure based on natural systems. An emerald necklace of parks, open space, and trails connects the Eastern Promenade to Back Cove, Mill Cove, Deering Oaks, and the Greater Portland. The buried arterial streets open up additional land for transit lines, walking, and bicycle commuting, thereby reducing overall carbon emissions in Portland, improving air quality and encouraging a more resilient, localized economy.

With Portland’s desire to grow, the ‘East Bayside’ neighborhood is a highly desirable investment opportunity due to large lot sizes and relative low costs. However, the predicted increase in sea level over the next century will erode the infill and the future landscape will more closely resemble the natural contours as seen in 1777.

Concept Summary
Many urban planners claim that cities are defined by the quality of their public spaces. While Portland provides many great parks, they are often bare, open fields lacking in design and interactive engagement. The Bayside Resiliency Park would provide heavy flood mitigation as well as a first class urban space for Portland. With small and large plantings, street furniture, water and light features, interactive platforms, and artwork, it would become a destination for visitors and a year long asset for the community.

BASE ASSUMPTIONS
6' of sea-level rise by 2100 Sea-level rise will reach 20' in the foreseeable future
KEY SCENARIO DESIGN ELEMENTS
Construct a pedestrian-oriented canal along the current alignment of the Bayside trail. Convert I-295 to a multi-modal avenue. Raise Franklin Street, Preble Street and Forest Avenue to the level of the multi-modal avenue.
KEY RESULTS
Canal allows Bayside to drain water effectively during storm events and creates a pedestrian destination. Former I-295 creates levee against rising sea-level and stitches the city to the water. Raised infrastructure in Bayside will be both protected from and prepared for inundation.

Cove or to construct flood gates at the location of Tukey's Bridge, making Back Cove a protected harbor. Projections for sea-level rise vary from 1' by 2100 to 6' by 2100. This plan calls for a canal to be installed by 2060 to prepare for 6' of rise by 2100 *. The canal would be used to drain the neighborhood from frequent flooding and would be effective for the 6' projection for sea-level rise.
The final element of plan calls for raising Franklin Street, Preble Street and Forest Avenue to be at the level of the new multi-modal corridor. This provides the opportunity for more buildings to be constructed with high and dry, urban, pedestrian-access frontage.
