Out with the Model Ordinance in with the Ordinance Guidebook and Workbook

September 23, 2026 / / 0 Comments

For many years, the Pennsylvania State Historic Preservation Office (PA SHPO) had a model historic preservation ordinance to help Pennsylvania’s municipalities protect historic places in their communities. The tool, while it had its uses, proved to be unequal to the task of accounting for the wide variety amongst Pennsylvania’s more than 2,500 municipalities. The model ordinance helped communities answer the question ‘how can we protect historic places,’ but it did not help communities address why they want to protect historic places or determine what residents in their communities valued.

The PA SHPO’s new Preservation Ordinance Guidebook and Workbook seeks to address not only how but also what and why to help communities develop implementable preservation ordinances which meet community needs.

Preventing Extinction: Saving the Last Wrought Iron Warren Pony Truss in PA

October 15, 2025 / / 4 Comments

On large stained and moss-covered stone masonry abutments over a single line of tracks in Tredyffrin Township, Chester County rested a dinosaur, a wrought iron relic of the past originally constructed to support the industry of a developing nation. Its appearance was worn and weathered from over 140 years of service.

Random holes and a mixed bag of fastener types and sizes littered the visible faces. The original railroad floor system was long gone and replaced with a timber vehicular deck. Its live load carrying capacity was a mere fraction of what it once was. However, under all of this rust was a diamond, a rare and complete example of a wrought iron pin-connected warren pony truss with built-up corrugated diagonal tension members, the last of its kind.

This is the story of relocation and reuse, adaptive reuse, of the last known remaining pin-connected wrought iron Warren pony truss in Pennsylvania – The Howellville Truss (2004RE01890).

Pennsylvania’s First Metropolitan State Park: A Brief History of Gifford Pinchot State Park

July 31, 2024 / / 5 Comments

A couple times each summer in the 1990’s my dad would pack us three kids into his truck and hook up the pop-up camper and head on over to ‘Pinchot’.  Arrival was a ton of work which often included setting up the camper, unloading the canoe, getting a fire set to light, and finding the nearest bathhouse.

But it was the anticipation of what was to come that kept us motivated. Riding bikes through the campground, swimming in the lake, fishing until dusk, spending time with each other and taking advantage of all the possible activities before us. Our imaginations in this place were limitless. What we always just simply called ‘Pinchot’ as many locals do, this place and all those who made it possible, shaped the principles of how my siblings and I understood the natural world around us.
