New Guidance from New Hampshire Department of Environmental Services
There are significant revisions to the regulations that govern land disturbance under the Alteration of Terrain program, a revamping of the New Hampshire Stormwater Manual, and a new handbook that we can use to help design projects.
- NH DES stormwater regulations, effective January 1, 2009, are available here>>
- NH DES has revised and updated the NH Stormwater Manual. The new manual comes in three volumes:
- Volume 1: Stormwater and Antidegradation
- Volume 2: Post-Construction Best Management Practices Selection and Design
- Volume 3: Erosion and Sediment Controls During Construction
The manual is available online here>>
- NH DES issued a guidance document titled, Innovative Land Use Planning Techniques: A Handbook for Sustainable Development, to address the need for guidance and technical assistance on Innovative Land Use Controls by municipalities. The handbook includes sections dealing with development density, environmental characteristics, and site level design. The document can be found here>

2009 UNHSC Porous Asphalt Specifications Review and Update
The UNHSC is reviewing and updating the asphalt mix and design specification this winter in preparation for next season’s installations. The specifications update should be completed by Spring 2009. Items that will be in the update include clarification of binder type, polymer modifiers, poly fiber quantities, curing time, small batch jobs and quality control, multiple lift installation, QC testing, and designated contacts for suppliers.

Salt Reduction for Pervious Pavements
Salting strategies are currently being studied to determine
if reduced amounts of salt are adequate for use on a porous
asphalt parking lot. Test-plot analyses, which include percentage
of snow and ice cover, undissolved crystal mass, pavement
temperature, dynamic friction factors, and required salt loads
compared to standard application rates, demonstrate that porous
asphalt requires as little as 0-25% less salt for winter maintenance
than standard pavement. Higher frictional properties were
recorded on porous asphalt with no salt addition than were
observed for standard asphalt with a full application. The
lack of standing water on porous asphalt greatly reduces the
number of required applications during freeze-thaw periods
and largely eliminates the formation of black ice. Report
should be available by Fall 2007.

NH Department of Transportation I-93 Exit
2 Gravel Wetland
The UNHSC has been collaborating with the NH Department
of Transportation and the project’s engineering consultant
design teams (Vanasse Hangen Brustlin, and Louis Berger Group)
involving the use of gravel wetlands as part of I-93 Corridor
Expansion. The use of gravel wetlands for this project was
instrumental to meeting permit requirements to prevent impacts
to impaired waters within the watershed. Pilot gravel wetlands
are planned for install in 2007. If the pilot projects are
successful, it is conceivable that the gravel wetlands will
be an integral component in future highway expansion.

The Rhode Island Coastal Resources
Management Council (CRMC) Seeks Improved Management of Stormwater
Runoff
As of Feb. 2007, CRMC prohibited the use of hydrodynamic
separators as the sole method of stormwater treatment for all
new development and redevelopment projects based on findings
at UNHSC and elsewhere. The recommendations are based on moderate
performance for these systems such that their usage will be
limited to pretreatment of stormwater. Similar restrictions
have occurred in other states in the region and the across the
country. More>>

Haley Soccer Fields, Kittery, ME
The UNHSC designed an integrated stormwater management
strategy for the town of Kittery for a new recreational complex
to be constructed in 2007. This project includes a bioretention/soccer
field, porous asphalt parking area, and a gravel wetland,
all to protect nearby Spruce Creek. Owner contact information

be constructed in summer 2007, includes a porous asphalt parking
lot and other LID strategies. More>>

MEDOT Engineered Filter Berms
The UNHSC is evaluating the performance of MEDOT Engineered
Filter Berms (2006-Present). The examination of a filter berm
is important as an innovative, low cost treatment modification
for roadside swales. The filter berm has an engineered filter
mix comprised of ½” angular stone and wood chips.
The filter mix is encased in larger 6” diameter stone
to hold it in place and resist erosion in large flows. The
importance of an effective swale retrofit is underscored by
the widespread usage of roadside swales for stormwater management
throughout the country.
