It took Express to end this 7-year nightmare
A series of special reports in the Daily Express on the matter the last several weeks were all that was needed to push officialdom, after seven years of complaints failed.
But the problem may not be over yet because the concrete deflector does look rather too small in case of an overwhelming torrent from a real deluge.
What is a bit more reassuring though is JKR has also finally sealed the large hole ripped apart from the top of the 50-ft concrete retaining wall during a flood several months ago.
The big hole exposed the soil behind the towering retaining wall to open percolation of rainfall this predisposing earth movement which could destabilise the wall itself .
According to the Chan family of Lot 11, 9 Lorong Palas, a rupture at the base of the wall did occur a couple of years back, oozing an alarming amount of mud out into the garden, igniting a worry that the wall could face collapse.
The rupture was disturbing enough to draw a visit from the Director General of City Hall, Datuk Yeo Boon Hai.
Although the two remedial responses from JKR were a bit satisfying for both the Chans and the Daily Express, it still didn't solve the big ponding problem on the Shantung Road above the wall.
Ponding at this critical spot may indeed cause a lot of storm water to percolate into the subgrade of the road and get transported through underground pores and saturate the soil behind the wall with excessive moisture.
The JKR must now work to eliminate the regular ponding at this high risk section of the forest road elevated high above KK city.

Questions about whether it should approve the unauthorized addition of fill to the waterside property of a house at 188 Redwood Road occupied the Sag Harbor Harbor Committees attention on Monday.
Joshua Schwartz, through the application for 188 Redwood LLC, has been before the board in recent months, seeking permission to have a 2-foot-tall, 76-foot-long retaining wall in a buffer zone that was planted with native plants. The committee previously approved a new bulkhead along the waterfront, but members balked at the need for a second retaining wall, arguing that Mr. Schwartz had added fill without a permit.
Thats important, the boards environmental consultant, Richard Warren, said, because what you are doing here is changing the flood plain.
On Tuesday, Mr. Schwartzs attorney, Dennis Downes, told the board that when earlier work was done at the property, about 50 yards of sandy fill was excavated and spread over the existing lawn. Another 10 yards of topsoil were added.
The committees chairman, Steven Clarke, had scolded Mr. Schwartz at an earlier meeting for putting in the fill and said on Tuesday he was not inclined to sign off on letting it stand.
We had lots of discussions with him about the project, Mr. Clarke said. I personally dont cut him any slack on that aspect at all.
Mr. Clarke proposed a compromise that would allow Mr. Schwartz to keep some of the fill and simply regrade it down to the buffer zone, eliminating the need for any retaining wall at all. When Mr. Downes protested that would punish his client, Mr. Clarke replied, The punishment in this situation would be to make him start over again without any additional fill.
The irony is he is asking for a retaining wall to protect stuff he put in without asking us, added member Tom Halten.
The committee tabled the matter and will revisit it at its next meeting.

Harbor Committee Has Questions About Fill
A pizza delivery driver escaped serious injury when a wall collapsed onto his vehicle in Mt. Washington on Saturday, a public safety spokeswoman said.
Sonya Toler said the driver had just parked on Virginia Avenue about 6:30 p.m., was out of the car and retrieving the food to deliver it when the retaining wall fell onto his car.
He was very fortunate and able to escape the collapse of the wall, Toler said.
However, the man did suffer an injury to his leg and went to a hospital for treatment, she said.
The box of pizza remains crushed on top of the car.
So far, police have not said what caused the collapse.

Stability will be to the fore as the Dunedin City Council casts a critical eye over more than 4000 of the city's retaining walls.
Over the next six months, contractors will be seen around Dunedin measuring and checking the soundness of about 3000 walls supporting roads or land and property next to a road.
The data, added to that from about 1300 walls in the city's metropolitan area that have already been assessed, will be forwarded to council staff, who will then complete a risk assessment exercise to identify which walls need attention, and when.
Council asset management engineer Geoff Young said the work had not been done before, and would help update the council's records so it could better manage its responsibility to maintain the road network.
''If you haven't measured something, you can't manage it, so we are looking to know what we have got, so we can better manage it.
"If that has a financial implication we need to know what that is, so we can set aside money for it.''
In most cases, the inspection could be carried out from the roadside or footpath, but at times inspectors would need to enter properties to gather the necessary information about the wall.
Some of the walls were privately owned, but the council was keen to record them where they could have an effect on the road.
In cases where a wall was at risk of imminent collapse, a letter would be sent to landowners informing them of the situation.
The council had the power to require property owners to fix retaining walls threatening public property but, in the main, this was an information gathering exercise, Mr Young said.

Soundness of retaining walls to be checked
Published: Monday, 12/8/2014 - Updated: 6 seconds ago GETTING FREEWAY READY FOR WINTER
BY DAVID PATCH BLADE STAFF WRITER
When a state contractor made one of the last concrete pours needed to finish a new retaining wall on I-75 near Detroit and Delaware avenues last week, it marked the move toward completion of the last task essential to keeping the freeways reconstruction through downtown Toledo on schedule through the winter.
The projects first phase, which includes rebuilding the two left lanes in each direction, the median wall, and associated drainage, was just 30 percent complete as of Thursday. But the retaining wall on the curve between Detroit and Delaware was the only critical path item remaining on this months schedule, said Theresa Pollick, an Ohio Department of Transportation spokesman in Bowling Green. It is expected that all of the concrete pours will be done by the end of the month.
Its moving along real well, said Mike Gramza, ODOTs district planning and engineering administrator. Shortly into the spring, we will switch [traffic] over to the inside lanes.
Rebuilding I-75 between Dorr Street and I-475 is among several ODOT projects set to continue in the winter.
Along with the Anthony Wayne Bridge rehabilitation, its among the more disruptive to traffic. Reducing I-75 to two lanes each way through has caused chronic backups since work began in July.
So far we are pleased with the work progress on this and all of the projects on the Interstate system, said Todd Audet, ODOTs district deputy director in Bowling Green. We hope the traveling public will remain vigilant and patient traversing the area as some of the project will continue through the winter.
Work planned for the winter includes demolishing the Oakwood Avenue overpass, which will be replaced; pouring concrete footers for overhead signs; hand pours for median-wall concrete at catch basins, and back-fill for the retaining wall. Ms. Pollick said the latter item could be finished yet this week, but most of the work schedule is weather-dependent.
Completing the downtown I-75 projects current phase on time in the spring, Ms. Pollick said, is vital because it affects the traffic pattern for ODOTs next I-75 project: freeway reconstruction and widening between I-475 and I-280.
