Table 1. Land use pattern in Colombo Municipal Council area The total land extent of the Colombo Municipal Council area is 11,115 ha. According to the available historical data, the main land use change observed in the Colombo city area is the rapid increase in built-up land, which is over 84% at present. This built-up area replaced domestic gardens, water bodies and marshes while a significant decline in the extent of domestic gardens observed, mainly due to migration to commercial crops. The localities under the proposed project predominantly consist of commercial and administrative/office type land uses while a considerable land cover is also under residential, parks-recreational uses, as well as waterways, roads and pavements. 4 Figure 1: Location map showing the locations of the toilets 5 3. Project Justification Need for the project Colombo is the financial and commercial capital of Sri Lanka with 800,000 permanent population and 500,000 floating population. There are 58 public toilets situated within the city. Existing public toilets are located at prominent places as well as close to the (What problem is the underserved settlements. project going to solve) Being a Local Authority responsible for providing almost all basic amenities to tax payers as well as a floating population, facilities of 14 public toilets in 14 locations have been selected to be improved under World Bank funding. During the selection following factors have been considered. • Floating population • Condition of existing toilets and facilities • Necessity of new constructions • Availability of land Purpose of the project Facilitating public health and hygiene is the main purpose of the project. (what is going to be achieved by carrying out the Toilets at the above 12 locations will be constructed with the project) following features (see Annexure 2 for detailed drawings and the designs): Alternatives considered No any other alternative is considered for the project as it is envisaged that there are no any other technically feasible and (different ways to meet the economically viable engineering interventions that could be project need and achieve accommodated in place of the proposed option. the project purpose) 6 4. Project Description Proposed The tenders documents will be ready for Package 1 on 30/12/2011 and Package 2 start date on 15/03/2011 and work construction of toilets is expected to be finished within a period of one year. Proposed It will take minimum 12 – 15 months to finish the project from the date of opening completion bid documents. date Estimated The project will be done in two packages. The estimated costs of the each package total cost are as follows. PACKAGE 1 Land Extent Estimated m² Cost Million Rs. 1 No. 112, Vauxhall Street, Colombo – 02 68.00 6.06 2 Galle Road/W.A.

Toilets at the above 12 locations will be constructed with the following features (with (see Annexure 2 for detailed drawings and he designs): supporting • Roof - Translucent Sheet for day light elimination material such as • Floor (Common Areas) - 600 mm x 600 mm non-Slip Floor Tiles. maps, • Toilet Areas - 300 mm x 300 mm non-Slip Floor Tiles. drawings • Interior Wall - 300 mm x 900 mm Polished Tiles. etc attached as • External Walls - Aluminum Cladding for easy maintenance. required) • Door /Windows - Color Bonded Aluminum Cladding Boards. • Sanitary Fittings - American Standard. • Electricity - Solar Power The following are the activities proposed under the project: – Demolition/dismantling of existing toilets, pavements and structures – Disposal of (above) debris – Re-orientation of service provisions and instrumentation (telecom, power, water and drainage) – Material Transport – Material storage and handling – Provision of temporary drainage – Diversion of traffic and traffic management plan – Diversion of pedestrian pathways – Construction of the superstructure for the new toilet – Construction of pipelines and drainage for the new toilet – Construction of septic tanks for the new toilet – Maintenance of toilets after commissioning – Gulley operations and disposal of sewage 8 MAINTENANCE PLAN Colombo Municipal Council is unable to maintain public toilets due to non- availability of conservancy labourers. Hence these public toilets will be maintained through private participation on contract. Already six public toilets are maintained on contract satisfactorily with following conditions. • Charge a maximum fee of Rs. 10/= per use from the user. • Settle service bills by the contractor. • Attend minor repairs up to Rs. 5,000/= by the contractor. • No alteration can be done by the contractor. • A performance bond of Rs. 25,000/= to be furnished. • A monthly payment of Rs. 67,200.00 (for the six toilets) to be made to Colombo Municipal Council. Project Agency: Manageme nt Team CMC will be responsible for the implementation of this proposed project. Nevertheless, A Project Management Unit (PMU) has been established under the Ministry of Defense and Urban Development (MoDUD) to implement the Metro Colombo Urban Development Project. The PMU will operate under the oversight of a Steering Committee, chaired by MoDUD’s Secretary and composed by SLLRDC, UDA, the PLAs, the Ministry of Provincial Councils and Local Authorities, the National Water Supply and Drainage Board and the Ministry of Irrigation. Other ministries and agencies will be identified as stand-by members, to be called when relevant issues need to be dealt with (e.g. Central Environmental Authority). While the PMU will remain responsible for the overall implementation of the project, responsibilities will be decentralized to the CMC for sub-projects designed and implemented by them. With regard to environmental safeguards, day to day compliance will be monitored by the Environmental Officer at the CMC (appointed specially for CMC projects under the MCUDP) while overall supervision support will be provided by the Environmental Specialist at the PMU. Contact person: Mrs. Dhammika, Chief Engineer, CMC; Nature of the consultation and input received: Meeting and consultation at design office and site were done. Design drawings, master plans and other relevant information were too gathered. 9 5. Description of the existing environment 5.1 Physical features – Ecosystem components Topography and terrain The topography of Sri Lanka is marked by great diversity caused by long years of faulting and erosion of the landscape. The central mountainous region with the highest elevations covered by virgin forests and grasslands rises up to about 2,500 m above mean sea level. The surrounding plains, which rise to about 50 to 100 m above sea level, are largely used for agriculture and homesteads, but still have virgin scrubland where the population distribution is lower. This general topography of the country can be divided into three distinct geographical areas or well marked peneplains featuring the coastal belt, the plains, and the central highlands. The Colombo district which incorporates the project area falls into so called lowest peneplain of Sri Lanka (after P.G.
