Can you give an update on the landslide between Starwood and Legacy Drive? We have been looking at it for almost 2 years without any work being done to fix it.

Starwood HOA hired a company to repair the slope failure back at the end of 2008 and finished at the beginning of 2009. The Legacy Slope failed again. Starwood HOA hired a new company that has been preparing the design of the second repair and the construction of it will begin in the spring of 2010.

There still hasn't been any visible activity to repair the landslide. Who can we contact to clean up the black tarps that have now slid down the hill and are laying in the street?

The city is working cooperatively with the affected HOAs to finalize a solution.

We have set a goal of the repair work commencing in June.

The city is in the process of removing the tarps.

May I ask, why is this a city issue? It appears to be a problem with the drainage, which should be the developer's responsibility.

Beginning in 2004, the City has been involved with the slope issues related to the construction of Legacy Drive. The City worked in cooperation with the developer in making repairs to the area north of where the present failure exists. At that time the City shared in one-third of the expense of getting a repair done with the other two-thirds being shared with the original developer of the subdivision and the party responsible for constructing the roadway.

When the current section failed, the City again worked with the owner and responsible party for the slope, in this case now Starwood Homeowners’ Association (HOA). Initially, the City engaged the services of a geotechnical firm to provide an investigation of the failure and to propose a remedy. City staff also assisted by obtaining pricing for the repair work in accordance with the recommendations of the geotechnical firm. It was necessary that the entire area of failure be removed and replaced with select fill and an under drain be established. Repairs to fencing and landscaping were also required.

It was agreed at that time the most cost effective and expeditious manner to proceed would be for the HOA to engage and contract for the work and the City to reimburse a portion of the expense. The HOA contracted for the work to be done, and it was completed. Unfortunately, there was a subsequent failure which is what is presently seen. During the intervening time, other slope failures occurred north of the railroad crossing along Legacy and also along Lebanon Road at the rail crossing. Moreover, due to the weather and soil conditions elsewhere in the Metroplex, other such failures occurred in similar situations – slopes along roadways. TxDot, NTTA, and other cities were engaged in making repairs to those slopes.

Because of the repeated failure along the Legacy section, the HOA and the City engaged additional geotechnical services to determine the best solution. The situation along Legacy and Lebanon pointed to the need for a comprehensive step with the City playing the lead role. The City Engineering Services Director, Paul Knippel, is coordinating the repair effort. It was felt that the best approach would be for the City to contract for the repair work and for the HOA to reimburse the City. This is in part for the reasons cited previously.

Ultimately, the City is responsible for the maintenance of Legacy Drive and Lebanon Road. The stability of the adjacent slopes is necessary for proper maintenance. As indicated previously, there are currently several existing slope failures related to the railroad underpasses of Lebanon Road and Legacy Drive. The problem has its origin in the soil type, the angle of the slope, and the moisture in the soil. The moisture in the soil is due to a combination of irrigation, rainfall, and shallow groundwater. Staff believes it is in the best interest of the City to assist in some form with the repair of these failures, and to bring a measure of coordination to the repair process for all of the failures. To that end, we are working with the Starwood HOA and other HOA’s in the immediate area to accomplish the work.

Please let me know if you have any further questions.

Any updates on this as it is almost the end of July and some mud/sand is getting onto Legacy causing some unfamiliar drivers to swerve or make a sudden lane change when they see the landlide.

Item 32 on last night's agenda contained a construction contract to repair this slope.

Work will begin approximately the last week in August.
