If you have a second vehicle...something, maybe you can park it in front of your driveway. Parking sounds a bit hectic around your driveway and cars could end up parking so close to your driveway that it will be difficult to exit your driveway. You're going to need a sign, paint, and maybe a second vehicle,preferably someone who lives in the same residence, to park in accordance with Seattle Municipal Code 11.72.110. Even if you have room for the second vehicle in your driveway, I suggest parking the second vehicle on the street so you will have at least one parking spot for a guest or a service member. This will only get worst in the warm seasons when more people are out and about.
