Community Support

Hi Mr. Rowley -

We are residents on Mandan Street in Phoenix where your company is currently building a drainage channel to prevent flooding from South Mountain.

We have worked in tandem with the Flood Control District and City of Phoenix since 2014 and were thrilled when the funding was approved for this project.

We have watched eagerly every day from our back yard at the progress of your team.It has been exciting to watch the various machines and the change in the landscape.

I want to commend your outstanding team led by Paul Vinke and Mason.There has not been any dust that we had expected to contend with.We had planned on bringing all patio furnishings in, but there was no need due to the continual watering that was being administered.

Any time we had an opportunity to speak with anyone, especially Paul, we have been received with smiles and a willingness to answer questions about the process.( Don`t worry - we tried not to keep anyone from their jobs, they all seemed happy to speak with us).

From the various machine operators to Paul, there is a sense of professionalism and pride in what they are doing.

We can`t begin to thank you for what you are doing to prevent future flooding.Our home has sustained severe flood damage from seven rainfalls since we moved here in 1980, so we are extremely appreciative of everything your company is doing.

We are anxious to see the completed project but are definitely enjoying the process.

In a world where people are not happy and are always finding something to complain about, we just wanted to let you know how grateful we are.

Thanks and congratulations on a terrific job.
