Contractors recently began work on $2.6 million worth of improvements to Glendale Park. During construction, the park will be closed and all of its entrances will be blocked. Built in the early 1900s, the approximately 4.5-acre park is one of Everett’s largest and most heavily used open spaces. It has playing fields — a baseball diamond and two softball fields — that serve the new high school, which opened in 2007. The project calls for installing a new irrigation system, improving drainage, and reseeding grass on the playing fields. New fencing will be placed around the field and new lighting installed. The walking path around the park perimeter will be rebuilt and lighting installed along the path. Other project features include replacing the current tot lot with one twice its size, adding new formal entrances to the park, and installing a new fence around it. There will also be new landscaping, benches, and trash receptacles. The project is being carried out with the help of a $500,000 state grant. Construction is expected to be completed by next fall.
