St. Joseph Neighborhood Center

Community

The objective of this project was to rehabilitate the historic St. Benedict School building in downtown St. Augustine and use it as a Neighborhood Center. Maverick provided civil design for associated utility connections, ADA connections to adjacent sidewalks, and stormwater management utilizing pervious pavers for the parking lot. The design incorporated efforts to have low environmental impact by working around the existing mature trees and using the pervious paver parking lot for dry retention.

We enjoyed working on this project, as the St. Joseph’s Neighborhood Center offers one-on-one counseling, educational opportunities, case management, and supportive services to low-income single mothers.

River City Science Academy Bayard (Southeast)

Educational

Public K-8 Charter School project with playfields, parking, utilities, a lift station, and stormwater management.

What made it unique:
