John Lamir of Lamir Landscaping in Darnestown takes a picture of the partial wall collapse along Quince Orchard Road in Gaithersburg. Lamir said he will use the picture as an example for clients of how to not build a retaining wall.
This story was updated at 12:30 p.m., April 1, 2014.
Two homeowners had to evacuate their homes after a retaining wall just steps from their properties gave way along Quince Orchard Road Sunday.
No one was injured when the retaining wall collapsed about 4:20 p.m., but two homes have been evacuated and the northbound lanes between Hillstone Road and Pawnee Drive were closed. Montgomery County police spokeswoman Cpl. Rebecca Innocenti said Monday the road could be closed for a few days.
The road was still shut down as of Tuesday morning, police spokeswoman Angela Cruz said.
A State Highway Administration surveyor Monday morning was assessing the damage to the wall. Gaithersburg City manager Tony Tomasello said the wall is owned by the Kentlands Community Association and is made of hundreds of concrete blocks, each weighing 200 pounds. Two townhouses at the end of the 100 block of Ridgepoint Place in the Kentlands community have been condemned by the city, according to a notice posted on the homes.
Tomasello said its unclear when residents will be able to move back into the homes.
Its still early in the process, Tomasello said Tuesday.
Carmela and Lyndon Thurner, who live at 112 Ridgepoint Place, were forced from their home and are now living in a nearby hotel with their two dogs.

Construction on the Opportunity Works satellite facility took a big step with the completion of its 5,300 square foot ReCon retaining wall system. Shea Concrete Products provided the blocks and structural engineering necessary for a project that began just a few months ago.
The property is divided into three separate walls with varying heights and widths. The largest of the three stands just under 14 feet tall and over 200 feet in length. The other two walls are both nearly 13 feet in height.
Opportunity Works is a notable nonprofit that helps a lot of people in the Merrimack Valley community, so it was a good opportunity for us to showcase our ReCon wall system in a place with a lot of foot traffic, said Shea Manager Greg Stratis. Unit Construction did a great job installing the walls and were very happy with the outcome.
The facility sits on a sloped piece of property, which led to the retaining wall installations. Engineer Phil Christiansen of Christiansen & Sergi, Inc. said the retaining walls were required due to the buildings parking area. Christiansen directly specified Sheas ReCon wall systems.
Ideally, for a big structure with a lot of parking, you want a flat piece of property but that wasnt the case here, he said. The only way to deal with that, considering the size of the building and the parking area requirement, was to put up a wall."
When you have a property like this one, the walls are in close proximity to where the people are, so it needs to look good and the Shea walls do look good. If you had a wall that wasnt attractive, it just takes away from the setting of the whole project.
Their product is nice to work with and their service is great, you cant beat their service as far as were concerned, said Jim Bowles of Unit Construction. The contracting company was responsible for installing the ReCon wall system and has worked with Shea for a number of years on a variety of projects. They also laid the walls for Sheas Amesbury, MA production plant.
Shea is quite helpful in that they do provide structural engineering for the walls and also provide a lot of advice, said Christiansen. Shea comes back to us with recommendations once we give them some parameters on length, height, and other specifications.
Opportunity Works is a nonprofit corporation that works to improve the quality of life for adults with developmental disabilities over the age of 22. Many have severe multiple disabilities and require complex program plans and individualized services. Their notable programs include community-based employment and day habilitation. They are coming up on 40 years of service in May.

WASHINGTON -- A retaining wall collapsed near Gaithersburg on Sunday, forcing evacuations and a road closure.
Three people have been evacuated from two town homes along Ridgepoint Place in the Kentlands area, says Pete Piringer, spokesman for Montgomery County Fire and Rescue.
"The homes were very close to this particular wall," Piringer says. "We did evacuate the homes as a precaution and have since called for the utilities to be shut off."
No one was injured in the collapse.
Piringer says that the ground under the wall is "very saturated" and "may still be shifting a bit." There have been problems with the retaining wall in the past, officials say.
The northbound lanes of Quince Orchard Road between Darnestown Road and Pawnee Drive could be closed for several days.
"It may be several days as engineers and inspectors need to check it," Gaithersburg Police Department spokesman Dan Lane said in an email.
Below is a map in the area of the road closure.

Wall collapse leads to closure of Mont. Co. road

Does a Google satellite photo show damage to the slope that gave way causing Saturdays Oso landslide?
A University of Washington professor says, after talking with the people who built a retaining wall at the base of the slope, he no longer thinks it was a factor in the slide.
Im probably pretty confident now that it was not a contributing factor, geologist Dave Montgomery told KING 5 on Friday.
The day before, Montgomery said that the image could show evidence that the Stillaguamish river was undermining the slope.
The image, photographed by a Google Earth satellite in July of 2013, clearly shows the log revetment," a retaining wall built by the Stillaguamish Tribe to keep sediments from the unstable hillside from harming salmon runs in the river.
At the northwest end of the wooden wall there is a jumble of logs and a crescent shape gap where the river appears to have cut into the slope.
