Update on Construction in Coastal Areas
In light of recent Massachusetts building code and regulatory changes, homeowners in coastal areas are increasingly wondering where to turn when evaluating the impact of these new code changes on their existing residences.
Recognizing that making sense of all these regulatory changes can be a daunting task, the Massachusetts Department of Public Safety and the Department of Environmental Protection (DEP) recently worked together to publish new standards for Flood-Resistant Construction and Construction in Coastal Dunes - incorporating both the state's residential building code revisions and the state wetland regulations.
The new Appendix G facilitates better consistency between the state building code and wetlands regulations -- and their permit approval processes.
These standards are spelled out in Appendix G of the new building code (effective retroactively to January 1, 2008), and establish the design and construction requirements for new and existing buildings and structures located in flood zones and/or in coastal wetland resource areas containing coastal dunes. The new Appendix G now also conforms to the National Flood Insurance program, and facilitates better coordination and consistency between the state's building and wetlands permit approval processes. |

Other Information Available
A handy guide to help homeowners understand how to protect coastal property from major storm damage is available at the wetlands protection page on the DEP's website - or view the pdf by clicking on the brochure image on the right.  More detailed information about the new 7th edition state residential building code is available online at the Department of Public Safety website - along with news and updates from the Board of Building Regulations and Standards (BBRS). |
| About Waterfront Property Inspections
Waterfront properties command higher real estate values, but come with greater environmental risks. Shorefront structures, such as docks, piers, bulkheads, and revetments, are coastal-engineered structures that are subjected to greater natural forces and environmental exposure than most residential buildings will ever experience in a lifetime. For this reason - coupled with the complexity of environmental regulations that affect the installation and maintenance of such structures - waterfront property owners should consider an evaluation inspection of their shorefront for both existing conditions and longer-term risks that may impact property values.
Typically, such an evaluation includes a conditional assessment of all existing coastal structures - which involves not only an engineering evaluation of the structures, but also a complete environmental permitting compliance assessment - as well as a review of long-term shorefront protection and maintenance issues.
And when it comes to regulatory requirements, local zoning regulations, building code compliance, and other environmental and health code statutes raise the bar of standards for waterfront properties. Whether engineering- or wetlands-related, issues concerning regulatory compliance and complex assessments of environmental impacts - such as flood zone and wastewater treatment issues - are involved when evaluating waterfront properties and shorefront structures.
In addition to these coastal engineering considerations, if a waterfront property owner is contemplating an addition, alteration, or change in use for any buildings, there are site development and structural building issues that also need to be addressed. A thorough property analysis can not only determine the construction cost impacts for compliance with the state's new residential building code regulations, but can also help homeowners in assessing the full development potential of their property.

Featured Project - A Residential Coastal Bulkhead and Foundation Replacement
The owners of this residential property, which fronts on scenic Provincetown Harbor, needed to replace an existing wooden bulkhead and house foundation that were no longer serviceable. Because the property is located within a flood zone, the new foundation and replacement bulkhead had to be designed in accordance with both state building code and FEMA coastal construction standards for flood-resistant construction.

Also, this featured article in the July 2008 issue of The Journal of Light Construction describes the engineered design and construction technique used for this project, where unstable soil and periodic tidal flooding were of concern to the project team. |
| Helpful Tips for Building and Remodeling Projects
Confused about how the state's new residential building code may affect your home improvement project? Here are some things to think about when planning any new construction or remodeling job:
1. Retain the services of a professional contractor* who is familiar with local and state building codes; redoing work that does not comply with building code requirements can be expensive. Before hiring a contractor, ask about their experience, education, and any professional certifications - and visit similar home improvement or remodeling projects the contractor has completed to inspect workmanship and get feedback from other homeowners.
2. If the proposed project involves plumbing or septic upgrades, contact your local utility locator service to mark the underground utilities before any contractor digs into the ground. Neglecting to have utilities marked - and accidentally digging into and damaging the existing services - can result in costly repair bills that the utility companies will require the homeowner to pay.
3. Most home improvement projects need a building permit, especially whenever structural work is involved or when the basic living area of the home is to be changed. If there are concerns about the home's structural viability, a licensed Professional Engineer (P.E.) who specializes in residential construction can provide information about a building's structural integrity that is not included in a standard home inspection report.
* To locate a professional contractor in the local area, contact the Home Builders and Remodelers Association of Cape Cod (HB&RACC) at 508-398-3900, or visit www.capecodbuilders.org. | |
