Better ways for a family with disabilities to enjoy Downtown Park

Hello! We are a family with young children (ages 3, 5 and 1) and both parents have a disability. We love spending time near Downtown Park - it really feels like the center of our community, and we think it’s very special that our “suburban” community has such a space. We live in a more suburban part of Redmond so we drive to this park specifically to feel that sense of community. However as a family with young kids, we have a couple of challenges with enjoying the park. The lack of a defined playground area there - with playground equipment to capture the kids interest and possibly a fence for safety - means our kids run too far away from us too fast, near busy streets. They instead play on the stage which is often slippery on wet days, with lots of sharp edges. Ultimately there are too many ways for them to get hurt here and not enough ways for them to play safely. And with disabled parents we can’t take that risk because we can’t get to them fast enough in such a large undefined area. So we avoid this park even though we’d really like to make use of it. We often look at this park and think - wow with so much space, the only thing they have for kids here is a water feature we can only use 3 months a year? It seems almost discriminatory against families with young kids - like we aren’t wanted there (for most of the year). It feels like we could carve out a small portion of this park to create a state of the art inclusive play area - in other cities we lived in before buying our long term home in Redmond, we saw some very cool accesible playgrounds that were not an eyesore and didn’t take over the whole vibe of the rest of the park.
Finally: Accessible parking could also be improved at Downtown park. The only spots I have found are along an extremely busy road and it’s unclear if my state placard allows me to park in the garage by Woodmark unpaid. Thank you for your consideration. I was so impressed with this feedback gathering process.
