 GEORGE TOWN: A cracked underground drain caused rainwater to flood the earth beneath a road in Tanjung Bungah, causing a retaining wall to burst open and creating a 10m-wide “cavern” beneath the road.

Residents along Lembah Permai woke up last Friday and found part of their street had caved in.

An abandoned house on lower grounds next to the street is teetering on the brink of collapse after water washed away the earth beneath the house’s foundation.

Where the opening of the 40cm-in-diameter underground drain used to be is now a maw around 10m across, with chunks of the wall lying down the slope.

The minor landslide brought back fearful memories for residents because it is less than 1km from the Tanjung Bungah landslide that happened in October 2017, which killed 11 construction workers.

“It was raining so much last week. The water from this drain comes from most of the roadside drains in hillside and it was gushing almost all day and night.

“Luckily, no one lives in that house now. It was abandoned many years ago,” said neighbour Teh Choon Pin.

When the southwest monsoon began on May 6, it was raining almost continuously for five days in Penang and this retaining wall burst open on the fifth day.

Resident Zuhaimi Che Mat, who lives just about 30m from the wall, said it was the first time this has happened in the 50 years she lived there.

R“The water from the drain flows into the stream heading out to sea. When it rains heavily, water from the hills comes gushing down the stream and out of the drain,” she said.

State Works Committee chairman Zairil Khir Johari, who is also Tanjung Bungah assemblyman, said the state approved an emergency fund of RM220,000 and a contractor has been appointed to start repair works.

“The underground drain had cracked and water was seeping into the soil and weakening the road foundation.

“We knew there were problems and the Public Works Department was in the process of calling for a tender before the wall burst open,” he said.

He said the hassle was that there were many utility cables and pipes running under the road that went down too.

“There is an 11kV electricity cable, water pipes, telephone cables and others. So many agencies will be involved in the repairs,” Zairil added.

The never ending torrential rain in Penang over the weekend was an act of God. A natural phenomenon which is a perpetual feature of our equatorial climate. Nobody would wish to have the heavens open up with such vengeance on any state.

Naturally, when the rain intensity is so great, floods will occur. We should always be vigilant during the annual monsoon season.

Flood mitigation starts from the local council and state government. Every council must take into consideration the terrain, rainfall and built up surfaces in their area. While we can always engineer ourselves out of a flood, there is always a cost versus benefit consideration. There are some low-lying areas in a flood plain that will perpetually be flooded when it rains and if we situate developments in those areas, we have to be prepared for such events.

On a small island like Penang, with its hilly terrain, engineering flood mitigation measures must be a long term and all-inclusive plan encompassing all urban growth zones. It will not be cheap, mainly due to the high land cost and the expense incurred to provide adequate storage for the surface runoff.

As the island develops, open permeable spaces will continue to diminish causing higher runoff to flow downstream into the coastal areas. Couple that with tidal phenomenon and the incoming surface runoff will easily overwhelm the drainage system causing a rise in water level.

The question we should all be asking is how do we reduce the incidence of flooding? Unfortunately, especially with our tropical climate, it is quite impossible to entirely eliminate flooding. Anybody that promises that is telling you a blatant lie.

With the right planning and engineering, we can reduce the incidence of flooding and lower the magnitude of the damage caused.

Penang’s terrain bears much similarity to Hong Kong. Being in the path of tropical storms and typhoons from the Pacific Ocean, Hong Kong bears the brunt of some of the regions worst storms. On average, six tropical cyclones slam into Hong Kong every year. While flooding still occurs in Hong Kong, they have managed to reduce the damage it causes.

There are many lessons Penang can learn from Hong Kong.

If DAP still wants to continue to develop the state in a sustainable manner, they must implement special flood mitigation requirements in addition to the ones provided by the JPS Masma manual. If the hills are being cleared, the increased runoff will tax the existing drainage system. Siltation will occur, evident from the brownish flood waters, as topsoil and sediment from the hills wash down into the coastal plain. These sediments, unless periodically maintained, will clog existing waterways, thus reducing drainage efficiency.

The ultimate problem with highly built up areas is the immense volume of runoff from storms. Sufficient storage areas in the form of retention ponds and green open areas should be provided to retard the flow of water into the rivers.

Due to its terrain and the high-density development on the island, it is expensive to provide adequate stormwater storage within a development.

Catchment areas next to hillslopes also have a large volume of runoff moving at a high velocity. The damaging effect of erosion is quite evident on many of these hill projects. Sometimes water currents are so strong, even paved roads can be ripped apart.

Some of the more innovative solutions for Hong Kong’s flooding problems like the underground stormwater storage system has worked very well over the years together with a comprehensive Drainage Master Plan.

The Drainage Services Department of the Hong Kong SAR constructed massive underground tanks to route surface runoff intercepted from uphill catchments during storms only to slowly release the stormwater into the natural waterways when the storm abates.

The Penang state government has a duty of care to the residents of Penang to ensure that disasters of such proportion should not happen.

Over the past four years, a total of 119 incidences of flooding has been recorded in Penang. Penang is an economic powerhouse and home to some of the world most high-tech electronics producers.

The state government has to provide a safe and secure environment for investor to house their production facilities and assets. Otherwise, multinationals might shun the island because of the cost of protecting and insuring their priceless assets. Productivity would be affected and the cost to remedy the damage.

We will only find out the true financial cost of this disaster over the next few weeks.

For Penang to recover from this tragedy, federal funding is required to repair all the damaged infrastructure within the state.

The very least they can do is to provide a COMPETENT flood mitigation plan for the state starting with a comprehensive Drainage Master Plan Study.

The Penang government has to be ACCOUNTABLE to the people and not private developers. If certain waterways and catchment areas have to be gazetted as permanent drainage and storage areas, then so be it.

The safety and well-being of the Rakyat has to come first. Lastly, in the interest of  TRANSPARENCY, Penang has to launch an inquiry into how the local council approved property developments on Class III slopes without adequate slope protection.

The collapse of many retaining structures and slope failures in such risky locations is cause to for concern because as of right now, any dwelling structure located downstream to those development could possibly be the scene for the next Highland Towers.

Penang tables election budget for 2018: higher defict of RM740.5mil, paints rosy economic picture ...


GEORGE TOWN: Penang has tabled a higher deficit state Budget of RM740.5million for the next fiscal year of 2018.

Chief Minister Lim Guan Eng when tabling the budget, stressed that it was an estimate and it can be reduced if the state records a higher revenue collection.

Among some of the initial highlights for the state was a free Rapid Penang bus service during peak rush hours in the mornings and evenings.

Allocations would also be given to aid the medical tourism and hi-tech manufacturing sectors.

Penang has tabled a projected budget deficit of RM748.5 million for next year, compared to a RM667 million deficit for this year as administration and living costs continue to escalate.

However, Chief Minister Lim Guan Eng stressed that the state has a unique distinction of tabling projected budget deficits every year yet recording actual surpluses.

Next year's operating expenditure is RM1.25 billion, while the forecast revenue collection is RM503.7 million.

The cost savings come principally through the open tender system and an efficient administration, Lim told the state legislative assembly today.

After some 10 years of facing various external economic challenges, Lim said the state's gross domestic product is projected to outstrip the national average growth of 5.2% for this year.

Penang is targeting a GDP growth of 6% this year with the main contribution coming from manufacturing and services, with farming also showing signs of promise through fish farming.

GDP per capita has increased from RM33,597 in 2010 to RM47,322 in 2016, a 30% increase. Penang's GDP per capita is the second highest in the country, behind only Kuala Lumpur.

From 2015 to the first half of 2017, Penang attracted a total of RM13.8 billion in approved Foreign Direct Investment (FDI).

Tourism has also grown with the number of passengers at the Penang International Airport (PIA) hitting 6.7 million passengers in 2016, exceeding the airport's capacity of 6.5 million passengers.

The success story in the last 10 years is reflected by annual budget surpluses since 2008, with accumulated budget surpluses over the eight year period between 2008 to 2015 reaching RM578 million.

Lim also announced a range of fresh initiatives, which pundits have described as a people-friendly fiscal plan designed to endear the state government to the voters with the next general election looming near.

> There is a "I Love Penang" card, which is a smartcard for all local residents that allows access to social amenities and benefits provided by the state. The public think tank Penang Institute will be the implementing agency for it, as they have been allocated a budget of RM4.5 million to produce and distribute the smartcards.

> A free public stage bus service was mooted during the daily peak hours in the mornings and evenings – it is aimed at reducing traffic congestion. The project is dependent on the cooperation of RapidPenang.

> Penang has allocated RM60 million to jumpstart a "Pinang Sihat" medical card programme for families whose combined household income is below RM5,000, where the state will subsidise treatment at private clinics.

A medical card will be issued to each recipient, who can only spend up to RM50 per visit to a panel of private clinics who are part of the Pinang Sihat scheme.

"This will help the recipients, who fall ill to see a doctor without worrying too much about expensive charges or travelling to government clinics that are far away from their homes," said Lim.

> The free mammogram examination scheme for women above 35 years shall continue. So far more than 10,000 women have benefited.

> The state will also be increasing the annual payouts for senior citizens and the disabled from RM100 to RM300 for next year.

> A maximum bonus payout of RM2,000 will be accorded to civil servants who have a good disciplinary record while those below par will only receive RM1,000.

> The state will also allocate RM10 million for hill slope protection efforts, as well as to conceive a study on climate change, and tackle illegal farming.

Later, there was a protest at Komtar, led by former Penang PAS Youth head Mohamed Hafiz Nordin, who urged the state government to rescind the alleged appointment of PKR secretary-general Datuk Saifuddin Nasution Ismail as the new Penang Islamic Religious Council president, replacing Permatang Pasir assemblyman Datuk Salleh Man.

Hafiz argued that Saifuddin was not a religious scholar, therefore he was not suitable for the post. Saifuddin's replied that holding protests is normal in a democracy.

Much ado about nothing


Penang govt also gave an election budget, says MCA leader


"Public housing shortage is serious in Penang. Badminton courts and swimming pools can be added into low and low medium-cost housing projects. Tang Heap Seng"

WHAT is wrong with an election budget?

“Election budgets are happy and beneficial things for the rakyat,” said party secretary Tang Heap Seng.

He, however, advised Pakatan Harapan politicians not to “criticise something but did the same themselves”.

“Many Pakatan politicians criticised the Federal Budget and the Penang government did exactly the same.

“They claimed the Federal Budget will help Barisan Nasional win the general election.

“But then, the Penang government also gave an election budget,” said Tang during a press conference at the Penang MCA headquarters in Transfer Road yesterday.

Among the Budget 2018 goodies were Childcare Aid of RM300 for Working Mothers, RM300 aid for each local vocational school students and one-year waiver of business licence for about 29,000 hawkers and traders.

On the state Budget for next year, Tang said while there were many benefits, he was puzzled by the allocation of RM275mil to build 82 badminton courts and four Olympic-sized swimming pools.

“While sports are crucial to a happy society, we wonder why the state paid little attention to Penang’s urgent problems.

“Public housing shortage is serious in Penang. If the government wants to provide badminton courts and swimming pools, these could be added into low and low medium-cost housing projects,” he said.

Penang Gerakan vice-chairman Oh Tong Keong and secretary Hng Chee Wey also issued statements yesterday, expressing bewilderment at the RM275mil allocation.

In contrast, the tabled development expenditure for state Drainage and Irrigation Department is RM12.3mil.

Penang Island City Council and Seberang Prai Municipal Council will spend RM20mil on flood mitigation and for hillslope protection, RM10mil was budgeted.

Tang also said the RM53mil budgeted for the development of Islam was commendable, but wondered why only RM1.1mil would be given to Penang Hindu Endowment Board next year.

He said Chief Minister Lim Guan Eng only mentioned that RM30mil was given to non-Islamic religious development since 2008 when he tabled the Budget.

He said it would be ideal to allocate RM30mil each for the development of Christianity, Hinduism, Taoism, Buddhism, Sikhism and other minor religions yearly.

In a statement as well, Penang Women’s Development Corporation applauded the RM300 yearly aid for each working mother under the age of 60 with children aged six and below through the state Budget.

Meanwhile, Lim clarified that the bonus for civil servants would come from the reserved funds of this year’s Budget.

Earlier, Pulau Betong assemblyman Datuk Dr Muhamad Farid Saad had expressed confusion, saying, “How could you give a bonus this year through a Budget for next year?”

FRUSTRATED by the never-ending flood problems in Penang, a group has got together to arrange a meeting with state representatives on Oct 29.

The group of 24 residents associations and management corporations believes that the blame game between Barisan Nasional and Pakatan Harapan politicians should be stopped as the floods have caused a lot of hardship to the people.

Spokesperson Meenakshi Raman said the group would have experts share data collected on floods in their respective areas at the briefing.

“We want to make a collective call to the state government to take the flood and hill erosion issues very seriously,” she said at a press conference at the Consumers Association of Penang in Jalan Masjid Negeri yesterday.

Meenakshi said the state representatives could use the data gathered at the briefing titled ‘Penang Flood: Call for Action’ and discuss the matter during the upcoming state assembly in November.

The briefing is open to the public and the venue and time will be announced later.

“Flood mitigation alone is inadequate. We want comprehensive action and a stop to unsafe overdevelopment at hill slopes,” said Meenakshi.

Representatives of residents groups from Bandar Baru Ayer Itam attended the press conference to voice their dissatisfaction over the repeated flooding in the township, especially in Lebuhraya Thean Tek, Jalan Thean Tek and Lintang Thean Tek.

The groups are from Tanjung Court Condominium, Desa Delima (Tower Blocks), Sri Impian, Fortune Court, Treasure Ville and Desa Baiduri. Tanjung Court Condominium residents ad-hoc group representative K. Suthakar said Lebuhraya Thean Tek in Bandar Baru Ayer Itam would be badly hit by floods every time there was heavy rain.

“The state government keeps saying that the Federal Government doesn’t give them enough money.

“Will the flooding problems go on for five or 10 more years? How long is this going to continue? We are suffering,” he said.

He urged MPs to attend the briefing as well so that they could bring up the flood issue in Parliament.

Later, the group showed photos of landslides that happened during the Sept 15 flooding at Fettes Park, Solok Tembaga and Sungai Ara.

They urged Chief Minister Lim Guan Eng to focus on resolving the flood issues.

Penang Opposition leader Datuk Jahara Hamid said it was a good initiative to hold the briefing as there was a need to better understand the concerns of the people.

“I can only confirm attendance after the venue and time have been fixed,” she said.

Meanwhile, PKR Penanti assemblyman Dr Norlela Ariffin said she would attend the briefing.
