It is interesting that you think it is a rush to pave over the crime scene. By my count, it is four months after the fact, the area has been gone over at least twice by LE (once originally and once during the "re-enactment"), it has been rained on, driven on, had many people visit it, had several vigils upon it. I'm not seeing any kind of rush, personally.And in those cases, the case had gone to trial (Jessica) or the victims had been found (Elizabeth and Lyric). Why in such a rush to pave over the crime scene?
I think that often, when there has been a kidnapping or violent crime (assumed to have happened at PTL because of what LE has said) in an area, the community tries to redress that area so it doesn't feel so creepy or dangerous. And they try to do it as soon as possible. In the case of Jessica Ridgeway, the park was named for her in October 2013, but that had been underway since before Austin Sigg's trial was supposed to start (even though he pleaded guilty and waived his trial). That park construction started in April, 2013.

http://denver.cbslocal.com/2012/11/30/jessica-ridgeway-honored-park-memorial/ It is my opinion that they chose that park because it was where she was supposed to meet a friend to walk to school. This would give it a very uncomfortable feel to the community.
In Heather's case, they haven't found her, but why leave the place she disappeared to be a reminder of something horrible? The community decided they'd rather have something less desolate. It makes sense to me from that point of view.
