A Sunday Drive observation: Palmetto Bay’s Coral Reef Park. Is protecting the grass more important that protecting the safety of pedestrians?

I will let the photos tell the story of what I saw on Sunday, February 17, 2013, at Coral Reef Park. This appeared to be a fully unattended SUV.  Note that the parks department has taken steps to prevent people from parking on the grass along the driveway to the East side (77 avenue) Parking lot (2nd photo - to the right - ropes and signs prevent parking on the grass, but not the sidewalks):

It is my opinion that the SUV creates more than just an inconsiderate situation for people that need to use the sidewalk running along the southbound lanes of 77 avenue.  The SUV is parked perpendicular to the street.  It appears that the vehicle was parked this way to in order to load or unload the equipment currently in use in the park. The sidewalk is completely blocked in is situated under the center of the vehicle. The driver of the SUV could have unloaded and parked in the ample parking located on site which would have been to the south of the event, rather than parking nearly equal distance to the east of this event, but the owner appears to have taken what he or see perceived to be a more convenient location.

Safety, not convenience, should be the number one consideration. From what I observed, any bicyclist, child not tricycle, pedestrian, stroller or wheelchair would have been required to actually cross over the white line into the southbound lanes of 77 Avenue to pass this vehicle. Please see the photo below to judge the proximity of the parking to the field.  It is my opinion that this SUV should have parked there, not blocking the sidewalk. When is there a good reason to block a sidewalk next to a busy road?
