“Understanding what all parties in a matter want allows workable solutions to be developed for our clients.”

Jonathan entered the legal profession with an educational background in the sciences and natural resources, and with professional experience as an environmental consultant.  As a partner at the firm, Jonathan advises clients on issues ranging from wetlands, endangered species and cultural resources to those involving brownfields remediation, sewage facilities, and real estate transactions and permitting.  Jonathan was lead environmental counsel to the Philadelphia Authority for Industrial Development in its acquisition of the Philadelphia Navy Yard, an approximately 1,400 acre former military base in south Philadelphia, a representation that continues today as he assists in its redevelopment as a vibrant mixed-use development.  Early in his career, Jonathan was a guest on-air commentator on “Court TV” discussing a citizen’s suit regarding a claim of harm to the American bald eagle.  More recently, Jonathan has been counsel to industrial clients and real estate development firms in avoiding and resolving enforcement actions regarding the management of stormwater, an area of recent and rapid regulatory change.

Outside of the office, Jonathan serves as Chairman of the Montgomery County Agricultural Land Preservation Board, and continues to work to improve his community by serving on the Board of the Perkiomen Watershed Conservancy. Jonathan bikes, kayaks and plays golf with his wife Carla and enjoys time with his two adult sons and their families.

He has represented clients ranging from real estate and commercial developers to municipalities on a number of matters including the following:

• counseling the Philadelphia Authority for Industrial Development ("PAID") on all environmental aspects of the transfer and redevelopment of two former military sites—the Philadelphia Navy Yard and the Defense Personnel Support Center;    
• negotiating a Consent Decree on behalf of Hovnanian Enterprises, Inc. to settle allegations by the USEPA regarding stormwater practices at its development sites nationwide,  including ongoing counseling on their stormwater compliance issues;
• counseling numerous residential, commercial, and industrial developers to obtain state and federal wetland permits, and resolve issues related to land development impacts to waters and wetlands, such as (1) assisting several national homebuilders in obtaining a Pennsylvania Chapter 105 and federal Section 404 wetland permit for a large-scale residential community in Chester County, Pennsylvania, (2) assisting a regional healthcare institution to obtain wetland permits for its new health care center in central New Jersey, (3) obtaining state and federal wetland permits on behalf of a Chester County,  Pennsylvania, developer of a mixed use residential-commercial project, (4) prosecuting one of the few successful administrative appeals of a jurisdictional determination issued by the U.S. Army Corps of Engineers, and (5) negotiating resolution of several alleged violations of wetlands laws, regulations, and permits with the state and federal government resulting in the issuance of after-the-fact permits, voluntary settlement agreements, and performance of Supplemental Environmental Projects;
• representing several municipalities and municipal authorities with respect to their sewage treatment plants and discharge permits issued for these plants, including Pennsylvania Act 537 sewage plans;
• assisting a regional developer to challenge, and ultimately reverse, a determination made by the Pennsylvania Department of Environmental Protection ("PADEP") at the request of a watershed association to upgrade the classification of a stream abutting the developer's property, allowing the project to proceed in a more timely manner;
• preparing and submitting a "private request" to PADEP resulting in the agency ordering a municipality to revise its Act 537 sewage plan to include a client's development project (Jonathan subsequently defended the municipality's appeal of PADEP's order);
• advising numerous clients on their rights and obligations with respect to state and federal threatened and endangered species, including bald eagles, bog turtles, red bellied turtles and Indiana bats; and
• counseling various developers on compliance with stormwater permits associated with earth disturbance activities, typically for land developments.
