Barely a month since the Norwalk River Valley Trail\u2019s demonstration loop was opened in Wilton, organizers are set to extend the trail another half-mile beginning this month \u2014 from Raymond Lane to Sharp Hill Road. At its Monday meeting, the Wilton Board of Selectmen voted to authorize a contract with Timber & Stone Trailbuilders for construction, though the Friends of the Norwalk River Valley Trail still need to raise $30,000 to fully fund the project \u2014 which will have a final price-tag of around $235,000, including \u201cancillary costs.\u201d The board took this step with the understanding an anonymous resident had offered to \u201cunderwrite\u201d the $30,000 if the Friends were unable to raise the money by the time bills are due. During the meeting, Patricia Sesto, director of Wilton\u2019s Environmental Affairs department, said construction on the second Wilton section of the trail is thanks in large part to a $75,000 matching gift to the Friends of the Norwalk River Valley Trail from Cliff and Norma Fox, of Wilton. Ms. Sesto also said Monday the excellent quality of the demonstration trail has inspired a number of generous donors to plan contributions for the project, which may one day run directly from Calf Pasture Beach in Norwalk to Rogers Park in Danbury. The construction of the next half-mile is expected to cost $235,000. The only worry about the project expressed by the selectmen was voiced by Second Selectman Hal Clark. \u201cMy only concern is that [Timber & Stone] is a small company,\u201d he said. \u201cWe don\u2019t know if they are going to be here in 10 years. But, having walked the trail a couple of times, I think they are doing things right.\u201d Corporate contribution The selectmen also inquired about the trail organization\u2019s outreach to Wilton\u2019s corporate community, which may benefit from the extension of the handicap-accessible hiking trail. Ms. Sesto said great strides had been made in connecting with the corporate community, and that the newly relocated Cannondale Sports Group was interested in being the trail\u2019s \u201ccorporate champion.\u201d Other businesses, Ms. Sesto said, have not been as quick to come to the trail\u2019s aid. \u201cOddly enough we\u2019re experiencing that it\u2019s not so easy,\u201d she said. \u201cCorporations have people knocking on their door all the time.\u201d She also said she hopes to get property owners at 1020 Westport Road involved, as their\u00a0 parking lot can be seen from the trail.
