I grew up in Cambridge, and I spent years in City Hall. Now I work in land use and permitting. That means I have watched the life sciences boom from the inside and the outside. I have seen what it brings to a city, as well as the anxiety. Innovation cities like Cambridge are powerful economic engines, but they are also places where real people live real lives. Balancing those two truths is the hard work of growth. No city like Cambridge highlights a tale of two cities and while this is not the fault of growth, it must be used to balance inequities.
Life Sciences Are a Blessing And A Symbol Of Change
There is no denying what life sciences have done for Cambridge. They have brought jobs, investment, global attention, and tax revenue that supports city services. They have attracted some of the brightest minds in the world, and they have driven discoveries that save lives. More importantly they provide the tax revenues for a vibrant array of city services and very low residential tax rates.
But success comes with pressure. Lab buildings are expensive and they compete directly with housing for land. They drive up commercial rents, which ripple into residential prices. They attract workers faster than housing can be built. Moreover they make the city look and feel differently.
To some what is the “Golden Goose” to others can feel like the root of inequity and imbalance. Good developers and institutional neighbors can change that.
Housing, job training, open space and affordable retail
In almost every innovation city, housing comes second. Tax base comes first and housing is expected to catch up later. That gap is where trouble starts. Developers cannot be expected to provide a mix of uses without direction from planners and the community.
In Cambridge, life sciences growth surged faster than housing supply. Zoning rules limited where and how much housing could be built. The result was predictable. Prices rose. Families doubled up. Longtime residents felt squeezed. Alternatively new housing also can freak longtime residents out. A vibrant mix of uses and an acknowledgement that residents need job training, scholarships, housing, parks , youth programs and affordable retail is critical. While on the council, I supported increasing housing density allowed in Industrial areas and required affordable housing in projects with 10 units or more. Later many of my rezonings required housing as a condition of building commercial buildings. While economics must be constantly factored in, these zoning changes worked to create housing in various sizes and for various income levels. These rezonings also required support for transportation infrastructure, job training, youth programs ,open space and vibrant local retail. In doing these things you can look the community in the eye and say growth does not have to mean gentrification.
Gentrification is a feeling and is a reality
Growth is often described as neutral or even universally good. It is not. Growth without guardrails pushes people out. For some New buildings feel like gentrification to others new soccer fields and bike lanes feel that way. Gentrification fears are often misused to support agendas and cause unnecessary fear and anxiety. Other times it’s a very real thing.
The people who feel it first are not always the loudest. Seniors on fixed incomes. Working families. Young people raised in the city who can no longer afford to live there as adults. These are the quiet losses that do not show up in reports . It might just be losing a store or a family we all love having to move out. Maybe its new neighbors are calling the police unnecessarily on a group of allegedly undesirable youth.
If innovation cities do not confront this reality honestly, they risk hollowing themselves out. You cannot build a healthy community if the people who make it run cannot afford to live there.
Zoning Is the Steering Wheel
Zoning and community benefits can level the playing field
For years, zoning in many innovative cities made it easier to build labs than housing. Height and density were often more flexible for commercial projects. Housing faced stricter limits and longer fights.
That imbalance was not accidental. Cities chased tax base and assumed housing would follow. The lesson we are learning now is that housing does not follow automatically. It needs policy support.
Smart zoning updates aim to correct that. Allowing multi-family housing by right. Encouraging mixed-use projects. Tying commercial growth to housing contributions. These are not anti-business moves. They are pro-city moves.
Economic Engines Need Social Infrastructure
Life sciences companies rely on more than lab space and a highly educated workforce. They rely on teachers, transit workers, nurses, service staff, and city employees. They rely on vibrant neighborhoods that attract talent.They want to be in places with culture and vibrancy.
If those people cannot live near their work, the engine sputters. Long commutes increase burnout. Talent becomes harder to retain. Inequality deepens.
Social infrastructure includes housing, schools, transit, and public space. Innovation cities that ignore this eventually pay for it in congestion, turnover, and social tension.
Permitting Should Reward Balance
Permitting is one of the few places where cities can shape outcomes project by project.
Projects that add density should add value. That value can take many forms. Affordable housing, transportation improvements, public spaces, or community facilities.
This is not about punishing developers. It is about aligning private investment with public goals. When the rules are clear, good developers plan for this from the start. The process works best when expectations are set up front. I have crafted zoning and community benefits agreements that validate actual impacts and create support for the needs of the community. Yes, the developer needs certain things but so does the community. Protect the Developer from themselves by requiring community interface and a zoning that is balanced.
Community Voices Matter, Even When They Are Uncomfortable
People who oppose growth are often labeled as anti-progress. That is too simple.
Most residents are not against growth. They are against being ignored. They are against change that happens to them instead of with them.
The community process works when it is honest. When cities say yes to growth but also say how they will protect residents. When tradeoffs are acknowledged instead of hidden. That transparency builds trust, even when not everyone agrees.
The Balance Is Not Static, stay present in bad times
Cities are living systems. What worked ten years ago may not work today.
Life sciences markets cycle. Housing demand shifts. Transportation patterns change. Cities have to be willing to adjust policies as conditions change. Markets hit highs and lows and cities go from spoiled to almost desperate. Zoning is a critical tool.
Right now, many innovation cities are seeing lab vacancies rise.Office already all but vanished. This presents an opportunity to catch up with housing but zoning alone is only one tool. The Market glut will mean higher residential taxes and budget cuts. What seemed like endless Life science demand must be replaced with creative zoning , tax breaks and marketing to fill empty space. That said while developers and owners are deflated the work to keep engaged with the community cannot stop. Anecdotally ,a down turn does not mean you stop sponsoring a local team or stop showing up at community events. Remember the community is also hurting so do not disappear. In fact this is a time to be present in solution driven conversations and community building. Trust me it will be noticed and rewarded.
