3 The Project Description

3.1 The Project Site

3.1.1 Site Location

The site for the Le Chaland Resort Hotel is located at Le Chaland in the district of Grand Port. The Site is shown on the 1:25000 regional map of Mauritius in Figure 3.1.1.1. The closest village is Plaine Magnien, some 5 km by road.

3.1.2 Site Ownership

The Project Site allocated to CJ as per the Letter of Intent from the Ministry of Housing and Lands has an approximate extent of 33A00 (13Ha 9289m2) being part of Pas Géometriques Mon Desért and Part of the Defence Land out of the initial 45A00 (18Ha 9939m2). The remaining 12A00 (5Ha 0650m2) will be occupied by the new Marine Training Establishment (MTE) of the Mauritius Police Force.

After the cadastral survey of the allocated plot, Figure 3.1.2.1 referring, the extent of the Site has been established as follows:

12A05.21p (5Ha 0870m²) of Pas Géométriques Mon Désert from the HWM up to the Pas Géométriques Line, and

19A22.35p (8Ha 1140m²) of Defence Land situated behind the Pas Géométriques line and under the jurisdiction of the Prime Minister’s Office

3.1.3 Site Boundaries

With reference to Figure 3.1.2.1, the project site is bordered by:

To the North – the existing private owned access to the La Cambuse Public Beach being part of the 65 arpents of private property owned by M.O.I.S.E. a subsidiary of Currimjee Jeewanjee & Co. Ltd;

To the South – High Water Mark of the Sea;

To the East – the site that will be used for the relocation of the Marine Training Establishment and National Coast Guard training school;

To the West – The future National Coast Guard Post and the La Cambuse Public Beach.

3.1.4 Site Topography

The details of the topography survey are given in Figure 3.1.4.1, levels being referred to Mean Sea Level.

The Topography Plan, duly signed by Messrs GEXIM, Sworn Land Surveyors is attached in this Report, in pursuance to Clause 18(1) (c) (ii) of the EPA (2002).

The marked topographical features of the Site are:

A steep beach, approximately 20% , concurring with the coarse granulometry of the sand existing on the beach

3.1.5 Site Occupancy

The project site allocated for the Le Chaland Resort Hotel has markedly been affected by human activity. The vegetation has been cleared at numerous locations for construction of structures, roads and other infrastructure as highlighted below:

3.1.5.1 Derelict Artefacts

On 14 October 2010, the National Heritage Trust Fund requested that CJ conducts a Cultural Heritage Impact Assessment (CHIA) study owing to a number of building remnants (platforms) found on the site. Dr Geoffrey and Mrs Françoise SUMMERS were appointed to conduct the study and the CHIA report has been submitted to the National Heritage Trust Fund on 06 June 2012. Correspondences between CJ and the National Heritage Fund have been reproduced in Appendix D.

Figure 3.1.5.1.1 refers. Thirty-four (34) building remnants or platforms have been identified on the 45 A site. Of the 34 platforms; only 13 are within the Hotel project area namely Structures 16, 25-30, 33-37 and 38.

Structures 16, 37 and 38 are located within the building zone of Le Chaland Resort Hotel and the remaining ten platforms identified are located within the 100m setback strip from the High Water Mark.

The remaining platforms are located within the site allocated for the relocation of the MTE/NCG.

With reference to the CHIA study, an assessment of cultural heritage value pertaining to the project development is as follows:

World War Two Sites

In the south of Mauritius, three sites dating from the World War Two that possess tangible integrity namely:

The inter-related coastal defences on Ile aux Aigrettes, Ile de la Passe and at Pointe Diable

On the mainland, along the coast between Mahébourg and Pointe Diable, there were related installations connected with flying boats and the storage of fuel and,

The establishment of a Royal Naval Air Station, HMS Sambur at Plaisance which at the end of the war was occupied by the Royal Air Force before becoming the civilian Sir Seewoosagur Ramgoolam International Airport. The site at Le Chaland forms part of a similar historical landscape and include land that was requisitioned during World War Two.

Assessment of Tangible Remains at Le Chaland

The tangible remains at Le Chaland can be subdivided into the present condition of building platforms and the assessment of Heritage Value of the Building Platforms. The present conditions of the Building Platforms on the Le Chaland Project Site relates that:

The most important buildings associated with the air base have long since disappeared

The platforms and related features on the part of the site schedule for development are of no architectural value or importance

The tangible heritage value of the platforms and related features as physical remains related to World War Two is slight

Most of the platforms have had their basalt cornerstones stolen and those to the north and northeast of the tarmac road are severely damaged by tree roots that have split the masonry apart and broken up the concrete floors

The assessment of tangible heritage of the building platforms within the hotel development area and the surrounding area has been summarised below:

All physical remains of cultural heritage significance (with one possible exception, structure 40) on the land for development seem to have been constructed in World War Two

“Ruins” on the surveyor’s plan are essentially building platforms associated with the main buildings, cesspit and soakaways. One exception is Structure 40 which is a standing basalt wall

Most of the platforms are of standard widths and lengths with the great majority being approximately the same size.

Structure 40 is a single piece of standing basalt wall that was later strengthened by the addition of reinforced concrete. The construction date of the basalt masonry is not clear and there is no indication in the archival material available that any building was constructed in this location before the land was requisitioned for the World War Two Naval Camp at Le Chaland

None of the World War Two building platforms and related features are preserved above foundation level

None of the World War Two building platforms are of any architectural merits and almost all platforms have had their cut basalt cornerstones stolen

The building platforms’ poor condition is partly the result of rampant vegetation growth, especially tree roots and partly because the cornerstones have been removed.

Some of these platforms are quite substantial owing to the fact that they were constructed on sloping terrain and the down-slope sides built up to level floors

Most of platforms to the northeast of the tarmac road in the NCG relocation area are severely damaged by tree roots in addition to having been robbed of their cornerstones

The standing NGC Dormitory and the related features, built in stages between the 1960s and 1990s are founded on and in part encase World War Two platforms. None of these structural elements merit restoration or preservation




Page 20

None of the standing concrete buildings erected in the 1960s and 1970s possess architectural, cultural or historical merit that would in any way require or justify their preservation

Intangible Cultural Heritage Assessment

Dr Geoffrey and Mrs Françoise SUMMERS stated that the foundations of buildings that were part of the World War Two Naval Camp at Le Chaland are physical representations of a formative part not only of Mauritian history but of mid-twentieth century global history and its aftermath.

They also stated that by themselves these low platforms of no architectural merit do not offer a visual understanding of the site and its historical significance but their documentation will provide the information needed for their intangible cultural heritage value to be preserved for future generations.

Tangible Heritage Integrity

Following the walk-through visits on the project site, the observations made are as follows:

Structures belonging to the same general complex of military buildings are partially concealed beneath the National Coast Guard Dormitory building and possibly beneath three concrete buildings of the Police Diving School

Remains doubtlessly exist, or once existed immediately to the northeast of the Police Diving School, within the grounds of the Shandrani Hotel

With respect to the above observation, it can be concluded that the site lacks integrity and has no significant tangible heritage value as:

The integrity of the extant ruins is greatly diminished Authenticity does not extend beyond the platforms or the building bases The World War Two complex has long been demolished to feature the Sir

Seewoosagur Ramgoolam International Airport The greatest significance within the vicinity of the project site is the evolution of

the Royal Naval Air Station and its associated meteorological station where the ultra modern airport is presently nearing completion.

In the light of the above observation on the project site, the main conclusions are:

Structures 20 and 38 are two exceptional buildings

Structure 17 is a set of washrooms with associated features, Structures 41 and 42

Structures 1 and associated structures 2 and 3 may have had the same functions but needs to be checked on the ground after clearance of vegetation

Two clusters of buildings, Structures 1 to 20 and Structures 21 to 38 have been identified.

It has not been possible to observe the complete subdivision of Structures 21 to 38 as they partly lie on the Shandrani Hotel Site.

the platforms of the temporary World War Two structures and later installations associated with naval recreation in post war years have no integrity as the greater part of the complex and most important of the military installations, including the




Page 21

airport buildings have been demolished to accommodate the modern SSR International airport, the Shandrani Hotel and the existing NCG facilities.

In term of function, it would appear that all of these structures were connected with accommodation, administration and perhaps training

No observation tower or installation for big guns, searchlights and the generation of electricity have been identified

after the 1940s, none of the maps and records consulted show any buildings still standing on the platforms

the existing platforms and associated features within the CJ’s premises do not need to be preserved as tangible cultural heritage

the building platforms do not have architectural merit

With reference to the CHIA report, the recommendations are:

A full inventory of the remains shall be produced before the commencement of the construction activities. This will include a fully documented document by photography and measured drawings of the platforms in the Hotel development area.

All the remains of the World War Two Naval Camp Complex which are accessible but outside the hotel development area should also be recorded at the earliest opportunity

Dr Geoffrey and Mrs Françoise SUMMERS stated that the sand dunes have been planted with filao trees which were primarily used for burning lime. The filao plantation would have disturbed and altered dunes, not least by flattening their crests. The filaos were planted up until the banning of burning coral to make lime in the 1960s.

The building platforms and other remains to the north of the tarmac road are badly damaged by vegetation and stone robbing. There seems to be no reason to preserve these bases

Remains of cesspits and similar features should be made safe and could be filled in or removed.

Structure 39, presently concealed by vegetation should be cleaned and recorded. Once recorded, they could be buried or filled to restore the natural profile of the dune

The corner of the standing stone wall (Structure 40) should be retained since this is the only piece of ruin that has any visual impact

None of the standing buildings warrant preservation

During the demolition of the existing concrete buildings, a heritage expert should be on hand to record the existence and dimension of any World War Two building platforms that may have been covered by the existing structures.

The main infrastructure forming part of the existing MTE site is as follows:

A 4.7m wide and 560m long asphalt road crossing the whole site starting from the MTE controlled gate located to the East of the Site and terminating at another gate at the public beach. This road is a continuity of the Le Chaland Road which ends at the MTE gate.

Approximately 2 070m2 (roughly 37m by 55m) of tarmac area used as Parade Platform and a tarred access about 4.3m wide and 120m long leading to the Platform from the above-mentioned asphalt road.

A Tennis Court of approximately 590m2 tarred surface.

A tarred area of approximately 790m2 (about 34m x 23m) located at the Dormitory Building Site.

3.1.5.3 Existing Utilities Crossing the Site

There exist a number of utilities infrastructures which currently cross the CJ Site. These are described hereunder with reference to Figure 3.1.5.3.1

3.1.5.3.1 Overhead Electricity Lines

An overhead 22kV line (un-insulated) crosses the Site from W to E from the Public Beach and feeds two 22kV/400V transformers on Site located respectively at:

The Dormitory – feeding the Dormitory and running back to feed the NCG Training School

The MTE Flats – feeding the block of flats

The line then follows past the Site where it changes into insulated cables before feeding the Shandrani Resort & Spa switchgear.

3.3.3 Wastewater Collection, Treatment & Disposal

3.3.3.1 Wastewater Collection and Transfer Strategy

The Le Chaland Resort Hotel will be equipped with a sewage collector network connected via a lifting station to the Waste Water Treatment Plant that will be constructed in the B.O.H M&E Services Compound.

The sewer collector network can be described as follows:

All domestic wastewater discharge points at the Guests accommodation units, Public Area, Spa, Dining Rooms, Restaurants, Kitchen, bars and lounges will be connected to the sewer mains via conventional connection manholes

Wastewater from the toilets from the public beach will be collected and transferred to the sewer network of the hotel complex;

The wastewater from the kitchen and staff canteen will transit through grease removal systems before they are discharged to the sewer network;

The wastewater from the new NCG complex will be collected via an internal sewer network and sent to a septic tank. The overflow of the septic tank will be connected to the sewer network of the hotel complex;

The sewer flows will be pumped to the WWTP by an appropriate lifting station where retention times will be minimised to avoid fermentation

The main pumping stations to be equipped with odour scrubber unit to minimise the risk of odour propagation

3.3.3.2 Wastewater Treatment Strategy The WWTP will be of the RBC type with a nominal capacity of 300m³/day. The process descriptions, typical layout and the hydraulic profile are given in Appendix H.

The location of the treatment plant is shown in Figure 3.2.6.1.

The WWTP will provide treatment up to tertiary level (filtering and sterilization) with denitrification and phosphate removal. The performance of the WWTP is recalled hereunder:

The Treated effluents will be stored in an irrigation tank and reused for irrigation of the landscaped areas within the hotel premises.

The quality of the treated effluents will conform to environmental standards for treated effluent as per EPA (2002) as amended in 2008.

Excess sludge from the WWTP will be stored in the enclosed anaerobic tanks and pumped at a frequency of at least once every 3 months by licensed wastewater carriers to the Roche Bois Pumping Station subject to the approval of the Wastewater Management Authority

3.3.4 Storm Water Collection and Disposal

The Storm Water Management Plan defines a strategy for managing the ‘post-development’ storm water runoff flowing within the development area and off-site since there is no nearby watercourses and drainage system.

In general, the topography of the upstream neighbouring land slopes in a south easterly direction whereas a major part of the project site slopes in a north westerly direction thus forming a natural valley around the site boundary. A natural swale shall be provided to capture the upstream runoff and from the site which shall thereafter discharge to the neighbouring land belonging to MOISE Ltd, a subsidiary of CJ.

In view of the fact that the site topography is undulating with relatively rapid soil infiltration rate, a catchment subdivision exercise was carried out to demarcate the lowest point where a soakaway shall be able to dispose of the generated flow within. Hence, each catchment will comprise of a disposal system.

8 Maximum permissible concentrations




Page 32

A network comprising of PVC and reinforced concrete pipes and catchpits at regular intervals and interchanges will capture and channel the generated runoff from building roofs, floor surfaces and any other impervious surfaces to the soakaway.

An estimate of peak flows for each catchment is made by applying the Modified Rational Method and using the outline network indicated on Figure 3.3.4.1.

The following assumptions have been made:

The catchments are treated as single units. Flow is estimated at the furthest point downstream, i.e the soakaway. Rainfall is uniformly distributed over the catchment and is constant over time for

any rainfall intensity. The rainfall data used is taken from the IDF Curves of the Mauritius Meteorological Services (MMS) at Vacoas.

80% of the catchment has assumed to be impervious.

Applying the following equation, Q = CIA

Where, Q (m3/s): Catchment Flow C: Runoff Coefficient – 0.8 I: Rainfall Intensity – Assuming a return period of 25 years and 10

min max rainfall duration, rainfall intensity – 2.4mm/min A: Catchment Area under consideration

Plate 3.4.3.1 – Existing Access to La Cambuse Public Beach




Page 35

CJ and OMNICANE have agreed to share the necessary land for the construction of a 10m wide road (7.0m carriageway + 2 x 1.5m reserves). The agreement letter for the land concession by OMNICANE is reproduced in Appendix E hereto. The road will start with a roundabout, some 450m before the existing access. The new La Cambuse Public Road will be constructed in accordance with the guidelines of RDA and TMRSU.

The preliminary design of the proposed new public road is shown in Figure 3.4.3.1. The main details of the road are:

Roundabout on the Le Chaland Road; Length of proposed road: 1300m; Width of carriageway: 7.0m; Road Reserve: 1.5m on each road side; Road side drains for proper disposal of stormwater; Street Lighting

A typical section of the road is given in Figure 3.4.3.2.

CJ has applied for a clearance from Road Development Authority vide correspondence ref: 2816/VB dated 24 August 2012. A copy of the correspondence with RDA is attached in Appendix D.

The existing untarred access will be used as a pedestrian and buggy path. A service gallery will be constructed at the centre of the access and will be used to lay all the underground pipes and cables for the Le Chaland Resort Hotel and also for the realignment of the existing utilities on site. The gallery will be constructed at the centre of the access in order to preserve the Badamier Trees along the sides of the access.

3.4.4 La Cambuse Public Beach Extension and Upgrading

CJ has been requested to provide facilities for the La Cambuse Public Beach by the MoH&L as per the Letter of Intent.

The Beach Authority will be consulted as per the Letter of Intent in view of the works that will be necessary for the extension and upgrading of the Public Beach.

As per the plan attached to the Letter of Intent, a proposed site has already been earmarked by the Ministry of Housing & Lands for the extension of the Public Beach. The proposed new public road will end up at the public beach extension site.

3.4.5 Realignment of the 22kV CEB Transmission Line

With reference to Figure 3.1.5.3.1, the existing electrical infrastructure occurring on Site can be described as follows:

A 22kV bare overhead CEB line crosses the site, starting from the public beach side to end at Shandrani Resort & Spa Hotel.

The 22kV overhead CEB line supplies two transformers on site, one is pole mounted, located at and feeding the Dormitory, a LV (400/230V) insulated line then runs back feeding the National Coast Guard Training School. The second transformer is ground mounted inside a plantroom which includes a ring main unit (RMU) and which is located at the NCG gate. This system feeds the Police Diving School apartment blocks.

From the CEB plantroom at the NCG gate the 22kV overhead line is insulated and heads towards Shandrani Resort & Spa hotel following the NCG access road. Close to the Shandrani Entrance, the overhead line drops underground to enter the Shandrani Resort & Spa Hotel site.

The 22kV line ends at the main HV switchgear of the Shandrani Resort & Spa Hotel.

The existing CEB transmission line will be realigned underground within the service gallery along the buggy path from the Public Beach up to Shandrani Resort & Spa prior to de-commissioning of the existing line.

Correspondences with the CEB have already been established for the realignment works and are given in Appendix D hereto.

3.4.6 Re-routing of Potable Water Supply to Public Beach

The potable water pipeline runs alongside the MTE access road on opposite side of the CEB lines. The pipeline is a 50mm HDPE laid partially buried and feeds the MTE Flats, MTE Dormitories, NCG Training School and presumably the Public Beach as well.

This pipe will be realigned along the new buggy path within the service gallery as stated in Section 3.4.1. CWA has been asked for their clearance in respect to the realignment works. The approval letter from CWA is given in Appendix D.

3.4.7 Realignment of Telecommunication Lines

All existing telecommunications cables crossing the site will be realigned along the buggy path.

Mauritius Telecom has been consulted through a meeting held on the 18 July 2012. Correspondences with Mauritius Telecom are given in Appendix D.

3.4.8 Preservation of Sand Dune

The sand dune of Le Chaland was formed during the Flandrian Period of the Holocene, from 7500 year BP during which the sea level rose at a reduced rate of about 1.1 mm/yr to stabilise close to its present position at about 2500 yr BP. The sand dune, except for the area occupied by the Coast Guards which has been levelled many years ago to make way for the various military installations, is relatively intact. Being subjected to external forces such wind and waves the dune is still active and very dynamic. With reference to the Ecological Impact Report, the main recommendations relevant to the sand dune on the Project Site are:

the lagoon and sand dune, proclaimed Environmentally Sensitive Areas, shall be protected from negative impacts during the construction and operation of the resort and hotel;

a 100m no construction buffer zone has been allowed for in the design of the project masterplan;

CJ has appointed Diospyros Ltd and Scenic Land Design Ltd to implement the landscape design for the project and develop an ecological management plan for the rejuvenation of the sand dune;




Page 37

the ecological restoration of the sand dune ecosystem is strongly recommended. The construction and development limitations imposed on this zone and the necessary cleaning up of the Casuarinas offer an important conservation opportunity to recreate and restore the unique coastal vegetation and ecosystem once present in the area;

the sand dune and coastal ecosystem restoration shall contribute to the value and prestige of the hotel and also enhance its aesthetic and recreational objectives;

the sand dune shall also restore the important ecosystem service, adding a buffer against the potential impacts of climate change and sea level rise.

The Ecological Impact Report has been reproduced in Appendix G.
