TEMASYA Anggun residents want the authorities to look into their concerns and put in mitigation measures to address the incoming LRT3 project that will run behind their neighbourhood in Glenmarie, Shah Alam.
“We are requesting for the LRT3 track to be moved 34m away from the back of our house, instead of the current 15m,” said Temasya Anggun Residents Association (Tara) chairman Maj (Rtd) Ravindar Singh.
“We are also requesting for a noise-absorbing parameter wall at a ‘line of sight’ height of about 9m, and for soundproof windows for the houses facing the LRT3 track and station.”
He said Tara had been in discussion with LRT3 project delivery partner MRCB George Kent Sdn Bhd (MRCBGK) since they found out about the project less than a year ago.
The LRT3 track in Temasya Anggun will run along Persiaran Kerjaya. A station (Station 8) will be located near the Persiaran Kerjaya and Jalan Kerjaya intersection.
Nineteen of the 60 semi-detached houses in Temasya Anggun are immediately affected by the project, as their backyards face Persiaran Kerjaya.
“We are concerned about the impact of the LRT3 project due to its proximity to our homes. Our issues include noise and dust pollution, vibration, environmental and traffic impact, as well as safety concerns,” said Ravindar, adding that some 200 residents live in Temasya Anggun.
“We are happy that Prasarana and MRCBGK agreed to move Station 8 further away from its original location.
“However, they have yet to mention the mitigation measures to address the project’s impact, as outlined in the Detailed Environmental Impact Assessment (DEIA) report done by Prasarana’s consultant.”
He said based on the DEIA report, existing vibration levels for Temasya Anggun were between 0.349 and 0.429mm/s, which was above the recommended 0.2mm/s level for residential buildings.
“We want assurance from Prasarana that the propagation of vibration through the ground and into buildings will not be above 0.4mm/s,” said Ravindar.
“The Environment Department (DOE) acknowledged in a letter that the predicted noise levels would be higher than the recommended safety levels, especially at night.
“The DEIA report states that sound emission level for LRT3 pass-by was assumed to be 87 dBA measured at 15m from track side (at train speed of 80 km/h) without noise shielding. This reading is above the recommended limits of between 70 and 76 dBA for our area.”
Although the DEIA included mitigating recommendations, Ravindar said residents were disappointed MRCBGK only proposed temporary barriers during the construction phase to solve a permanent issue.
“Selangor fire department confirmed in a written reply that the architectural building plan for the LRT3 had not been approved,” he said.
“We also have safety concerns. The widening of Persiaran Kerjaya for the project is expected to reduce the distance between residents’ backyard fence and the road to about a metre. Any vehicle moving along Persiaran Kerjaya or turning from Jalan Pengaturcara U1/51 could hit one of the houses,” he added.
LRT3 is a rail service that will connect Bandar Utama in Petaling Jaya to Johan Setia in Klang. It will have 26 stations along its 37km route.
Construction started in the second quarter of 2017 and is expected to be completed by 2020.
MRCBGK project director Ong Gin Lip said in a statement that Prasarana and MRCBGK had deliberated on the best course of action to address Tara’s concerns.
“While not all requests can be met, Prasarana and MRCBGK have agreed on changes that can be made without affecting the rest of the alignment and have informed Tara via a letter on Feb 22,” he said.
“The changes made included moving the station 80m away from its previously proposed location so it is closer to the DRB-Hicom area, and redesigning the station from an ‘island platform’ to a ‘side platform’, pushing the alignment further away from the Temasya Anggun perimeter wall by an extra six metres.”
To mitigate the noise level, Ong said MRCBGK would implement noise control measures as per the Planning Guidelines for Environmental Noise Limits and Control, and constantly monitor noise and vibration levels.
“To mitigate noise from LRT3 service operations, noise barriers shall be installed on the viaducts at Temasya Anggun.
“The resulting noise levels from future LRT3 trains pass-by shall comply with DOE’s DEIA approval limits for trains pass-by and be subjectively lower (quieter) than existing road traffic noise at Temasya Anggun.”
On vibration concerns, Ong said that based on a three-month baseline study also witnessed by residents, the measurement showed the vibration levels were within permissible limits.
“A soil investigation test done by MRCBGK found the ground to be stable,” he highlighted.
“We will implement mitigation measures such as constructing trenches (where feasible) to reduce propagation of vibration, placing vibrometers during construction stage to monitor vibration levels and installing temporary retaining walls and sedimentation fences to contain soil erosion.
“Vibrations from transit trains on elevated structures, based on measurements at the piers from existing Kelana Jaya and Ampang lines, showed LRT trains’ vibrations to be lower than road traffic-induced vibrations,” he pointed out.
He said MRCBGK had submitted the architectural building plan to Selangor fire department.
“We would like to assure residents and the public that all safety and mitigation measures have been considered and will be taken during the construction stage.
“We will also work with the contractor to repair the potholes if the road was found damaged due to LRT3 work,” he added.
