More than 32 Boston Crown Castle employees spent a recent day at Nira Rock in Jamaica Plain removing invasive species, weeding and cleaned up adjacent to the playground. On May 9th, Crown Castle hosted a day of service as part of its Connected by Good community parks initiative. Doubling its efforts from last year, Crown Castle identified 22 parks in 20 of the company’s largest markets. Employees spent the day planting, building, painting and improving public spaces. The company-wide program focuses on improving and enhancing parks across the country.
