I've seen bulldozers around the regional park, but couldn't find any information.  I reached out to Ramsey County and received this response.

The proposed Lion's Park in New Brighton is a collaborative park project between the city of New Brighton and Ramsey County Parks & Recreation. The New Brighton city portion of park will be located just to the south of Long Lake Regional Park and will include a softball field, lacrosse/multi-purpose field, play area, trails and related park amenities. Ramsey County is planning park development that will complement the new park, including a park shelter, nature play area, trails, restrooms, parking lot and additional park amenities within the portion of Long Lake Regional Park that is directly adjacent to Lion's Park. As a part of the Lion's Park development project, a shared parking lot, trail connections and associated site grading and utility improvements will be made to allow future amenities to be completed.

Please let me know if you have any further questions.
