Greenman Dan

A Unique Landscape Company

We Are A New Orleans Area Stormwater & Landscape Company

We’ve grown to become a very different landscape company in the New Orleans area because our mission is to not only provide beautiful landscapes, but we are laser-focused on managing stormwater runoff which is created by our heavy rains. Our difference has caught national attention and has been written about on CNN Money and Fast Company. With Greenman Dan on the job you can rest assured that all of your project needs will be taken care of in a timely and professional manner by one of the more experienced landscapers and green infrastructure company in the New Orleans area

Who is Greenman Dan?

Exceeding our clients expectations is the goal of our founder Daniel Johnson, who has turned a lifelong passion for nature and working outdoors into a successful New Orleans stormwater management and landscape construction company.

Dan also takes an active part in the following organizations:
  • Louisiana Irrigation Association, President
  • Louisiana Horticulture Commission, Member
  • National Green Infrastructure Oversight Committee, Member
  • New Orleans Workforce Development Board, Member

Dan Johnson started Greenman Dan, Inc., in 2007 with a passion for solving drainage problems. During the rebuilding of his home after Hurricane Katrina, he experienced first-hand what fear and anxiety felt like when his home was on the verge of being flooded each time it rained. After protecting his home with french drains and watching their performance during the next big rain storm, he found his anxiety was no longer there and instead felt his home was safe and secure. Dan’s goal is to help others build their properties using green infrastructure (green infrastructure is a fancy term for building an outdoor environment to handle rain water as it would in nature; hold back, absorb, filter) so they are more protected and prepared to manage rain water and improve the drainage in their yard and neighborhood.  

Today, we have completed more than 1000 green infrastructure projects creating beautiful, functional landscapes in the Greater New Orleans area. Our ultimate goal is to help manage the stormwater runoff generated by our region’s intense rain events. This concept has garnered us national attention, and we have been featured in CNN Money and Fast Company. Call us to discuss your (many budget-friendly) green infrastructure options.
