Portland's NBA squad has been heavily involved in funding fun, all-abilities play areas in the state for kids for the past 7 years ... and 2021 will be no different, the team announced Tuesday.

This year, the Blazers and Lillard say they're passing along $25,000 to the city of Astoria -- which is about 100 miles northwest of Portland -- to aid in the building of the new playground.

The place promises to be awesome ... it'll allow typical kids to play with others that might require wheelchairs or walkers without any sort of restrictions.

And, if you're unfamiliar, these kinds of parks are SUPER important to families with special needs children because they help break stigmas and include EVERYBODY.

You'll recall ... NFL star Drew Brees helped build a similar fully inclusive playground in the New Orleans area back in 2017 -- and it turned out GREAT!

Here's to hoping the same happens in Astoria.
