"Significant Retaining Walls" at McKenney Hills school site

The Environmental Planning Division of the Montgomery County Planning Board has released their report on the McKenney Hills Elementary School site. On page 9 of the report is the following statement about the development of the site:

"Use of significant retaining walls to prevent grading from

 extending unnecessarily into forested lands."

Significant retaining walls? What does that mean? How many? Height? Length? How did the Planning Division come to this conclusion? Retaining walls aren't shown on the artist's renderings of the new school that were shown to the Board of Education.  

How is MCPS addressing the potential issues of safety, security and graffiti that come with "significant" retaining walls on a school site? 

Tonight - October 19, 2010 at the Sligo Middle School media center at 7 PM MCPS will be making a presentation about the McKenney Hills school site. Will the details of the "significant" retaining walls at this school site be revealed? 

Stay tuned.  A "significant" retaining wall could be coming to a school near you!
