Andrew Tilton, P.E.
Andy is the Director of the Water Resources market group. He has been with Johnson Engineering since 1978 and is a shareholder of the company. Andy provides quality control on the projects under design and permitting such as Ford Street Filter Marsh and Northern Everglades Potential Environmental Storage (NE_PES) projects. Andy is District Engineer for independent special districts such as Telegraph Cypress Water Management District, Babcock Ranch Community Independent Special District and Walnut Creek Community Development District. These districts are governed by Chapters 298, 189, and 190 of the Florida Statutes respectively. He also assists with the engineering for several Community Development Districts in Lee and Collier Counties. Andy has served as the senior engineer for surface water on many of the firm’s roadway projects for Hendry County, Lee County Department of Transportation, City of Cape Coral, City of Fort Myers, Collier County and the Florida Department of Transportation. He provides direction for monitoring, permitting, design and construction related issues. Andy is very active in the conceptual phase of the larger projects. He transitions the work to other water resource team members as the project is designed and permitted. Each project has watershed level issues to determine related to backwater profiles for setting site elevations and flood analysis, setting control elevations, measuring flows for calibration and working with the groundwater and environmental considerations of each site.
Ricardo Acosta, P.E., CFM
Rick joined Johnson Engineering in February of 2006 and worked on several development projects. Rick has now developed his capabilities as a stormwater engineer on the surface water management team. He has designed and permitted surface water management systems for an assorted type of projects through SFWMD and SWFWMD, including transportation (roadways, bridges and railroads), environmental restoration, commercial, industrial and residential. He has served as project manager on various projects, including the Stormwater Improvements to the Basin III of the City of Naples, the construction of the Powell Creek Preserve Filter Marsh in Lee County and the expansion of the South Central Florida Express Railroad system in Hendry County.
Rick has performed numerous analyses according to the FEMA’s Guidance to determine the impacts of Proposed Developments in Regulatory Floodways for a variety of projects. He has worked on projects that are relatively simple to those that are relatively complex with acceptance by the local review agency.

Jordan’s experience as an engineer includes stormwater drainage design, regulatory permitting, water quality modeling, well design and construction, construction inspection, groundwater testing and analysis, water demand calculations, technical report writing, data analysis, engineering due diligence, and expert witness engineering reports. Jordan also has experience in flow modeling, including gravity pipe systems, pressure pipe systems, open channels, flood routing analysis, and groundwater.
Alfredo Perez, P.E.
Alfredo joined Johnson Engineering in 2005 as a survey CAD technician and now works as an engineer on our water resources team. He has seven years of prior survey experience and is familiar with both office and field procedures for data collection and global positioning systems. Alfredo continued his education as a part-time student while transitioning into engineering within the company. He works on a variety of projects entailing various disciplines of engineering which include: groundwater, utilities, surface water, construction inspection, report writing, and field data collection. His diverse experience allows him to assist all areas of engineering, surveying and mapping, and preparing plans and specifications.
Erik Howard, P.E, P.S.M., LEED AP, CGC, CFC
Erik is a licensed engineer, water well contractor, plumbing contractor, and general contractor in the State of Florida. His experience as an engineer includes well design, permitting, certification, construction administration, well construction, rehabilitation and development, groundwater modeling, data analysis, and pump station design. He routinely prepares specialized plans and specifications for projects that require an ‘outside-of-the-box’ approach. Erik’s technical background and practical experience allow him to handle any groundwater well project, whether it’s a simple piezometric data analysis or complex and troublesome deep injection well issue. Erik has worked on more than 60 well projects in the past three years as a water well contractor. As an engineer, he has overseen the construction and testing of more than 30 wells with depths up to 1,379 feet and casing diameters up to 30 inches.
