Home values in Greenwich Village have increased 300 percent since the Hudson River Park plan was announced in 1990, according to a study released today by the not-for-profit group Friends of Hudson River Park. That is 100 percent more than the overall increase in Manhattan for the 18-year period. The Greenwich Village section of the park was completed in 2003, and between 2002 and 2005, home values rose 55 percent and the average sales price rose 135 percent, the study said. Friends of Hudson River Park is now recommending the creation of a Business Improvement District for the park, which spans from Battery Park City to Clinton, to create three commercial districts, including the redevelopment of Pier 40, which would generate funding for the park’s maintenance and operating costs.
