(Herald / Bob Eddy) Civil works projects in neighborhoods on two sides of Randolph Village are making good use of a lengthened summer before buttoning up for colder weather and resumption next spring.

Approved by a $2M bond vote in 2016, extensive service infrastructure will be followed by new sidewalks, curbing, road rebuilding and paving in the Prospect and Elm Street neighborhoods. Of Dubois & King design and oversight, the projects are contracted to Willistonbased Engineers Construction.

Elm Street

The neighborhood at the top of Elm Street was developed on land farmed by Harold and Grace Farr until the late ’60s.

Over half a century later, infrastructure replacement and upgrades are in the works. Street drains for surface water were not originally installed. Homes still on septic systems are being connected to the village sewer. Additionally, a new water main is being installed at a lower depth.

New stormwater rules require the building of detention ponds in civil construction projects involving more than an acre. Ponds are not required when simply repaving; digging into sub-grade triggers jurisdiction.

The first evidence of the Elm Street project was the arrival this spring of large pre-cast concrete culverts and detention pond trench boxes. Until August, most of the work was confined to the new pond area across from Mariah Road, where Elm Street becomes Mason Road.

The detention area is designed to let stormwater with surface pollutants, like oil, percolate into the ground, rather than flow directly into Ayers Brook and into the White and Connecticut Rivers. There are two pond areas, the first designed to handle and treat average storms. This bay is followed by a larger detention pond, for 25-year storm run-off. With even larger storms, like Irene, water will overflow both spillways, pass beneath Elm Street, and into the brook.

The detention system will require some maintenance, as the town will have to muck out sediments every few years.

Prospect Avenue

Across the village, the neighborhood surrounding Prospect Avenue is also undergoing substantial construction this summer. This part of the village was developed on the old fairground before the first World War, a half-century and more before the 60s development of Farr Farm.

Here, too, water, sewer, and street drains are being replaced, followed by sidewalks, curbing, and paving.

In about a month, both projects will be stilled until spring.
