Watching Irma

By Nell Ziehl, Chief, Office of Planning, Education and Outreach

As Hurricane Irma bears down, threatening southern Florida, I keep returning to what is precious about that place for me. My family and many of my childhood friends live in Tampa and St. Petersburg, well within the vulnerable area recently highlighted by the Washington Post. I was born there, not too far from where my mother and my grandmother were born. The connection is live, and I’m worried about my people.

But what else persists? From my great-grandparents’ time, some buildings still stand. My grandmother’s house still stands, I think. Emotionally, I can’t separate the historic bungalow cottages from the live oaks or from the pelicans standing on the bay’s stone wall. The pink bricks that pave my sister’s street warm and glow in the sun — the fabric and the light are equally important. Every year, our family gathers at the beach in one of the few small-scale, family-run motels left, a few doors down from the Don CeSar, a towering remnant of Florida’s early resort industry. Although the Gulf itself draws us, still full of life and beauty, these places also matter – the human record of their construction, their imprint of time and place, the memories and attachments formed there.

At the same time, our cultural heritage includes a heritage of loss. We understand that hurricanes come and go and that buildings, piers and even roads are ephemeral. Left alone, the landscape will reconquer. And behaviors also persist. After generations of weathering storms, many locals do not evacuate, despite news that the storms are not the same. Even armed with better knowledge about water management and the importance of ecosystem restoration to protect inland areas (not to mention the biological habitat and tourism dollars), Florida continues to permit development in ways and in places that are unsustainable, potentially exacerbating disasters and jeopardizing recovery.

As we move forward into an uncertain future, with climate change fueling rising tides and more dangerous storms, we must adapt in ways that take all of these elements into account. What is the spirit of the place? What should we protect? What *can* we protect? And what do we need to change?

Too often, our regulatory and philosophical frameworks force divisions between the “built environment” and the surrounding ecosystems, even though the full character of a place includes the architecture, infrastructure, streetscape, waterways, plants, animals – and the people who live there. Cultural heritage is cultural memory, and that includes traditional and historic ways of adapting to the natural environment, including storms. And when buildings collapse, when the tangible fails, the intangible remains valuable and can inform a more resilient future.

Preservationists sometimes focus on limiting rather than accommodating change. But we, more than many other professions, have the ability to understand the evolution of a community over time and to help manage change in ways that protect quality of life and respect the character of place. I pray that Irma passes by without much damage. But more storms will come, and how we respond and rebuild will determine what we can carry forward.

Preparing for Future Floods

As we turn from Ellicott City’s disaster response to recovery, and watch hurricanes threaten Florida and Hawaii, it’s hard not to think about all the places throughout Maryland that are prone to flooding. We built our earliest towns, cities, roads and rail lines along the Chesapeake Bay and its tributaries. As ports and fishing industries boomed, we developed more. And let’s be honest: we all love to live and play near water. Continue reading

Solar Panels and Tax Credits

By Melissa Archer, Preservation Officer

Summer is upon us, and with longer days and higher energy bills, many Marylanders are looking for ways to save money and conserve energy. With advancements in technology, government incentives and flexible leasing options, installation of photovoltaic systems are becoming more appealing and accessible. This summer the MHT blog will feature a series of posts exploring how historic preservation and green technology can work together. This first post will discuss how state historic tax credits can be used for solar energy projects.

The Sustainable Communities Tax Credit exists to promote the rehabilitation and reuse of commercial and residential historic structures across the state. What a lot of people don’t realize is that installation of mechanical systems, like HVAC, water heaters, etc. are eligible rehabilitation expenses that qualify for the 20% income tax credit. This includes systems that incorporate green technology, like geothermal and solar panels.

A parapet wall on a building's roof can conceal solar panels from the public right-of-way.

This applies to both commercial and owner-occupied properties that are “certified” historic by MHT. To find out if your property qualifies, please check the program pages for details. In order for the expenditures to qualify for the credit, the system must be purchased rather than leased.

The work must also be consistent with the Secretary of the Interior’s Standards for Rehabilitation. This means that the system must be compatible with the historic building, it must be reversible, and it must not destroy or conceal character-defining historic features.

How do you know if your solar project would qualify for historic tax credits? To determine if your project is eligible, you must submit an application to be reviewed by MHT prior to starting work. In the meantime, though, here are a few examples of situations in which historic tax credits may be an option:

Flat roofs can be used for solar infrastructure.

Flat roofs can be used for solar infrastructure.

1) Flat roofed structures

Properties with large, flat or gently-sloped roofs are ideal candidates for solar panels. In this situation, panels should be set back from the ends of the building so they are not visible from the public right of way. Roofs with parapet walls can also provide an excellent opportunity to conceal panels. In order to ensure that units are not visible, it is always a good idea to do a mock-up on the roof prior to installation.

2) Structures with non-historic additions

Additions might be an appropriate location for solar panels.

Additions might be an appropriate location for solar panels.

If your building’s roof is a gable, gambrel, pyramid or other prominent roof type, it will be difficult to install solar panels in a way that will not diminish the historic integrity of the structure.  A non-historic addition, however, may be able to accommodate panels in a way that minimally impacts the historic structure.  Solar panels on additions are reviewed on a case-by-case basis and factors to consider include the age of the addition, the roofing material, visual prominence, and surrounding landscape.

3) Properties with a lot of land

In some cases a property owner may be able to avoid negatively impacting the historic structure by installing solar ground-mounted panels instead. This works best for properties with a lot of acreage where panels can be set back a considerable distance from the historic structure and roads.  Special considerations should be given to properties located on significant cultural landscapes like battlefields as well as areas with potential archeological resources.

Unfortunately, many historic buildings do not have the roof type, orientation, visibility conditions, etc., that will permit unobtrusive solar panel installation. In those situations, solar co-ops may be an appropriate solution. This arrangement would not qualify for historic tax credits, but in many cases it may be the best solution.
