Representative Cases

Zoning and Land Development

  • Successfully represented a township in defending a substantive challenge by a quarry owner seeking to expand an existing quarry into a residential district. Carl effectively demonstrated that, despite regulation by the Department of Environmental Protection, the quarry operations continued to adversely effect surrounding residences.
  • Successfully resolved a significant curative-amendment challenge by a real-estate developer seeking to place mobile homes in a residential district zoned for one-acre lots. Carl presented an effective case on the negative impact on the local infrastructure from implementing this development project. Following a year of hearings, Carl was able to convince the township to approve smaller lot sizes for single-family homes.
  • Successfully represented a major pharmaceutical company in opposing a zoning application by a radio-station owner to locate a 50,000-watt AM radio station near the company’s newly constructed research facilities. Through comprehensive research and extensive interviews with a variety of planners and radio experts, he convinced the zoning hearing board of the potential adverse impact of the radio station. After three years of hearings, the zoning board agreed with the facts Carl presented and denied the application.

Condominium and Homeowners’ Associations

  • Created over 150 homeowners’ associations and condominium associations throughout Bucks and Montgomery Counties. He has represented numerous developers in establishing programs which enabled the smooth and effective transition of operations to newly created homeowners’ associations. He also has represented developers of condominium-conversion projects to effectively follow through on all rules and regulations required under the Pennsylvania Uniform Condominium Act.
  • Represented various existing condominium and homeowners’ associations in reviewing and revising their operating declarations and by-laws to adhere to existing and newly enacted regulations.

Eminent-Domain Proceedings

  • Participated in all aspects of the eminent-domain process in Pennsylvania, from the filing of a declaration of taking and posting of estimated just compensation to hearings before the board of view in jury trials.
  • Successfully defended a township against charges of collusion with a developer whose land benefited from a condemnation for a sewage-treatment plant. Carl was able to demonstrate that the plant was being constructed for a public purpose, notwithstanding the incidental benefit to the developer.
  • Obtained a substantial award from a Board of View for a landowner in a PennDOT condemnation of land for a by-pass off-ramp. Carl successfully demonstrated the impact of the taking on the development value of the property.
