I live in the area and have been following this. As far as I know the main car loop will stay the same or very close to the same. The small upper parking lot will be lost but be replaced by a nice little plaza.
Upgraded odour control is promised. There was some talk about re-aligning some of the trails in the park as some don't make sense where they begin and end. There is potential for a bathroom although some residents are opposed as they think it will increase the beach overnighting population. And of course there is the proposed bike lane from Clover to Ogden which will be an amazing amenity if it gets built (I think even some folks that hate downtown bike lanes will accept that an off street bike route along here is a boon for tourists and locals.)
As a near neighbour to this project I am cautiously optimistic.
Thanks for the clarification, nerka!
