Golfing on the banks of the Diyawanna Oya
By Hiranthi Fernando
Many travelling past the scenic Diyawanna Oya on the Parliament Drive would wonder what the work going on before the Battaramulla turnoff is all about. The project in progress is a new golf course, estimated to cost over Rs. 1.4 billion under the Diyawanna Oya project for the development of marshlands. Falling within the Kaduwela Pradeshiya Sabha, the project envisages a golf course with water theme park, ponds and nature parks.

First mooted in 1997, with the Urban Development Authority (UDA) as the project proponent, the agreement was signed by the developer, Asia Pacific Golf Courses Ltd., UDA and the Board of Investment (BOI) in August 2001. The drainage plan was given by the Sri Lanka Land Reclamation and Development Corporation (SLLRDC), the consultant in storm water management, in January this year. Work commenced in February.

The land, which was vested in the UDA, has been identified as a flood detention area by the SLLRDC, an official of the UDA explained. There have been heavy demands for divesting ownership. There are also threats of unauthorised filling by squatters and encroachers as well as garbage dumping, all of which are harmful to the environment. Therefore, the best solution, they felt would be to have a project compatible with the flood detention requirements.

Part of this land lies within a nature sanctuary. The marshland has to be retained as far as possible so that the wetland bird sanctuary can be recreated. The golf course project has been given the green light under specific conditions as it is compatible with the flood detention requirements of the area.

"The whole project has been worked out in consultation with SLLRDC, in conjunction with the flood storage requirements," the UDA official said. Part of the 225 acres of land has been given on a 99-year lease and the rest on a licence agreement. The oya bordering the land is being doubled in width so that it will be almost like a lake. While the greens, fairways and tees are to be raised above flood level, the fair weather driving range and two playgrounds will be at a lower level so that during rainy weather, it can take on the flood detention function. Under the agreement, the two playgrounds are being constructed at the developer's expense for the Kaduwela Pradeshiya Sabha. Upstream, a lake for pleasure boating and four nature parks, mostly water based, at the developer's expense, would also act as flood detention ponds.

Over 60% of the land would be water and marsh, with lots of culverts and bridges. The clubhouse is being built on high ground where no additional filling is required. Certain other levels have been brought down to compensate for the filling required for the 100 small golf cottages that would be built at a later stage of the project. The golf course and playgrounds are expected to take three years since earthwork cannot be undertaken during rainy weather. The water theme park, for which the developer could charge an entrance fee, and the golf cottages would be constructed thereafter.

The Ministry of Western Region Development, which is now the approving agency, has instructed the UDA to monitor the project. "Regular monitoring meetings will be held with the SLLRDC, UDA and the developer," the UDA official said. "If they do not act according to the master plan, the agreement can be terminated. This is a good compromise method of managing these flood detention areas rather than letting them lie idle for garbage or unauthorised filling."

"Since the area is within and bordering a major reserve, part of which is a wild life reserve, the Central Environmental Authority called a Scoping Committee," said Keerthi Jayawardena, DGM Research and Design, SLLRDC. "It was decided that an Environmental Impact Assessment (EIA) should be carried out. The UDA as the project proponent, commissioned the National Building and Research Organisation (NBRO) to carry out the EIA. We also participated in the storm water drainage and hydraulics aspect of the EIA. Approval was given in 1999."

Mr. Jayawardena said the levels are taken by the SLLRDC to determine whether some areas can be excavated and others filled to maintain the flood detention capacity.

The work seems to be carried out according to plan but each stage would have to be monitored. The lands, which had been acquired by the UDA in the 1980s, were originally paddy lands but could not be cultivated due to the stagnation of water. Owners who could establish ownership were paid compensation. "There was a proposal earlier to move the army mechanical workshop to this site," Mr. Jayawardena said. "However, this project is hydraulically better as it merges with the concept of a green belt around Parliament."

According to the agreement, conditions have been specified for the disposal of sewage, drainage of water, use of pesticides and weedicides and monitoring. The conditions require that the project approving authority be informed of any alterations and fresh approvals obtained. When a project is abandoned, the site should be restored to a condition specified by the approving authority. Further, SLLRDC should be consulted at every stage of development, before proceeding to the next stage.

At the site, three teams of workers are busy with excavator machines, widening the existing canal. The peat excavated from the oya is being dumped on the areas where the main playing areas are to be located. Temporary access roads have been made for the machinery, which cannot be taken on the soft peat of the marshland. When the course is done, secondary areas of play, raised to 1.5m will provide narrow pathways between the playing areas. An access road is being made to the clubhouse. "The canal is being expanded to 80 metres. The excavated earth is used to fill little islands in the marsh, with the least disturbance to the rest of the landscape," said Dilshan Ferdinando, Representative of Asia Pacific Golf Courses. The playing areas would be little islands among the natural vegetation of the area. Due to the acidity of the soil, only a few varieties of trees have been found to be growing on it. The clumps of trees were being saved as far as possible to provide welcome patches of shade, with the undergrowth only being cleaned up.

Mr. Ferdinando said the excavation was undertaken at enormous cost. "We are only allowed to fill 48 acres of the land," he added. "Whatever we fill, the waterway has to be dredged by an equal area." A drain is being constructed round the periphery of the land to treat detergents and other effluents that are being discharged from the built up areas surrounding the land naturally so that the course does not get polluted by it.

Mr. Ferdinando said the first stage of the work is to dredge the canal and complete the holes 1-4. The layout has been designed by an experienced golf course Architect, David Griffith. A layer of kabok soil will be introduced over the peat and a specially designed topsoil would be used. Expert opinion is being sought regarding the planting of grass on the playing areas "We are thinking of using a local grass suitable for the area, as an imported hybrid variety may be attacked by local fungi," he said. When the driving range is ready the planting of grass will commence on it.

About sixty acres of the land will remain under UDA ownership to be developed and maintained by a developing company. This project is a long term one and its fruits would be best seen in ten years' time, Mr. Ferdinando commented. Although the initial outlay on laying out the golf course is staggeringly high, exceeding Rs. 1.4 billion, he is confident that it would be a profitable venture. The Directors of the developing company are themselves keen golfers and know what they are doing. "Golf enthusiasts from countries such as Japan come here for extended golfing holidays, paying huge amounts as club membership fees, green fees and so on. This golf course will definitely be an attraction."
