Short Term Action. Long Term Change.  


Urban Implementation is a pre-vitalization consulting firm.  We conceptualize, design, and build innovative solutions for your city and neighborhoods.  Our “get it done” approach results in innovative, creative projects that are efficiently executed on time and on budget.     

Our focus is on temporary use activations of vacant or abandoned properties, temporary and permanent street scape design, and public art installations.  Our projects are designed to reduce slum and blight, improve economic activity, and enhance the quality of life.  

Urban Implementation’s principals, Brad Knoefler and Mark Lesniak, have been conceptualizing, designing, building and implementing temporary parks, public art, and streetscapes in Downtown Miami since 2009.  Brad and Mark were co-recipients of the Urban Environmental League's 2012 Orchid Award for Excellence in Advocacy for the Environment.  Our projects have been featured on NPR, the Miami Herald, the Tactical Urbanism Handbook, and the cover of the Downtown Miami Art Guide. 

Here are some examples of our work.

Execution & Implementation




The Miami Walls

In 2012 we installed over 180,000 square feet of murals over twelve buildings in Downtown Miami.  Working with renowned L.A.-based artists, RISK, who curated the installation with collaborative works by himself and Shepard Fairy, Mear One, Anthony Lister, and others.  


The Miami Wall 

The Miami Wall is over four buildings.  It is inspired by the sea, sky and sun we love in Miami.  


Peace and justice

This mural by RISK and Shepard Fairy (scene here in production) has become an iconic part of the Miami landscape and a popular "selfie" destination for tourists.


"A hardscrabble neighborhood transmuted with promise."

- Miami Herald


A 5-acre pop-up park on the site of the former Miami Arena designed as a multi-use public space capable of generating revenue for rent, staff, maintenance and improvements.  It was the largest pop-up park constructed in the United States.  Constructed in ninety (90) days, the completed park included two hundred and fifty (250) native species of trees, a three-and-a-half-acre lawn, and a sloping amphitheater-shaped berm made with re-purposed debris of the demolished Miami Arena.  During its two-year term Grand Central Park hosted numerous community events and ticketed concerts drawing tens of thousands of visitors to Downtown Miami generating millions of dollars of economic activity in the area.  It was featured as a key redevelopment driver in Tactical Urbanism Vol 2 (p.54).        (



Skate Spot

Skate Parks are the new town squares

Urban Implementation built Downtown Miami's first skate park.  After installing the basic infrastructure we turned over the skate spot to the local skate community.  This DIY skate spot was built by the skate boarders and became a spring board for more, better and permanent skating facilities to be developed in Miami.  

Park(ing) Day

rethinking how we use public property

Urban Implementation designed the Park as a platform for ideas and other innovative uses for public land.  Park(ing) Day is an international event that takes place in over 180 countries in over 300 locations worldwide.  We did the first Park(ing) Day in Miami at the future site of Grand Central Park as a way to promote the project and also promote alternative uses for parking infrastructure as public green space.  



People make the place

Urban Implementation built the Park as a multi-use space that could host concerts and community events in order to cover operating expenses and act as an economic engine for the neighborhood.  Events such as the 12,000 person Swedish House Mafia concert and other shows subsequently brought hundreds of thousands of people into the area for the first time and reintroducing them to Downtown Miami in a positive way.  We worked closely with government and non-governmental organizations to develop an innovative legal framework that allowed for on-going programming.  

Community Engagement

starting conversations

Urban Implementation's vision for the Park was as a platform for other uses by community organizations.  Generating revenue from concerts allowed for free or subsidized rents and production costs for public interest programming.  Pictured above is an open air seminar about urbanism in Miami.  Other community events included hosting Miami's monthly critical mass ride and Go Dutch!.   


Walkable cities start with walkable sidewalks.  Weedbombing is part art, part activism and all fun.  Urban Implementation identified high traffic areas in Downtown Miami where the weeds had overgrown the sidewalks. Then we painted them.  The project was designed to convert blight into beauty, improve walkability and raise awareness about maintenance issues.  Local students and artists volunteered their time and the entire experience became a positive community event .

A holistic approach to neighborhood building 

In 2010, Grand Central, a newly opened live music venue in Downtown Miami engaged Urban Implementation to conceptualize, design and build improvements to its surrounding neighborhood in order to make their patrons feel more welcomed and safe.  We hired local residents and homeless to landscape, fix curbs, paint streets, clean sidewalks and act as liaisons.  Over One Million people attended events at Grand Central before it closed in 2015.
