Contact snohomish county parks. Ago to snohomish county's website for their number.
The following is not legal advice. Yes. Make contact with ther property owner about dangerous trees. Due diligence. They need to have the opportunity to assess the situation. If you don't give them notice, they are not liable for damages. As noted above.. this is not legal advice...
Though it will not address your immediate concern, I believe that you have the right (by law) to trim branches that overhang your property. Note: I am not an attorney and my understanding maybe incorrect. Either way the best course of action is to contact park management ASAP and discuss it with them.
