    • The name "Bangalore" represents an anglicised version of the Kannada language name, "Bengaḷūru“. The earliest reference to the name "Bengaluru" was found in a 9th century Western Ganga Dynasty stone inscription on a "vīra gallu" (a rock edict extolling the virtues of a warrior). In this inscription found in Begur, "Bengaluru" is referred to as a place in which a battle was fought in 890 CE. It states that the place was part of the Ganga Kingdom until 1004 and was known as "Bengaval-uru", the "City of Guards“ in Halegannada (Old Kannada). 1791  This map was prepared on 22nd March, 1791 by Lord Cornwallis.  Comprised of today’s Avenue Road, Chickpet and surrounding areas.  The town was enclosed by thick hedges or bushes, and a strong fort adjoining it at the south part.  The Peta was the actual city within walls.  It is now called the old city area.  Tipu Sultan was then the ruler.  Lord Cornwallis attacked and successfully captured Bangalore and its fort.  The British made Srirangapatna their military base, after the whole of Mysore came under their control.  Since Bangalore had a better climate, they moved the military base to Bangalore in 1809. 1876  The City’s governance changed hands between its founding in 1537 and 1831, when the British took over the city’s administration.  In 1809, the Cantonment was established by the British which resulted in building administration and residential areas for British Military.  1881, saw roads named after military conventions - Infantry road, Brigade road and Artillery road.  In 1893, the plague broke out, and a ‘Plague Camp’ was created in the south of Richmond Town.  Around 1900s, the present day Malleshwaram and Basavangudi also formed. MORPHOLOGY
    • 1889  In 1889 a Committee was constituted for the development of City ‘extensions’ to meet the demands of a growing population. During the first quarter of the 20thcentury a number of newly planned development 'extensions' were developed with regular roads, open spaces and provisions for civic amenities (e.g. Fraser Town, Richmond Town, Sankarapuram and Viveswarapuram). 1924 • The Dharmambudi tank is now Majestic Bus stand, the Sampangi Tank is now Kanteerva Stadium and Challaghatta lake is now the Golf Course. • Domlur and Kormangala were not a part of the city, but were tiny villages. 1945  However, there was no comprehensive approach for guiding the growth of the City in an integrated manner. As a result irregular developments occurred in between these extension areas. To deal with this situation, the City Improvement Trust was constituted in 1945 under special statute (Bangalore City Improvement Trust Board Act, 1945). 1949  In 1949 the two cities were merged and the establishment of a number of key industries stimulated growth that resulted in an unprecedented 5.10 lakhs to 9.91 lakhs population increase during the 1941-51 inter-censal period. In an attempt to cope with this rapid growth, a Committee was set up by the Government of Karnataka in 1952 to draw up a Development Plan, including broad land use proposals. But, in the main, the proposals were not implemented as there was no legal backing to enforce the Plan. To address this Government constituted the Bangalore Metropolitan Planning Board to prepare a Master Plan for the metropolitan region with the assistance of the State Town Planning Department. The result was the Outline Development Plan (ODP) for the Bangalore Metropolitan Region. This Plan was adopted by the Planning Authority constituted under the Karnataka Town and Country Planning Act , 1961 and was finally approved by the Government in 1972. This Plan represented the first step towards a Development Plan for Bangalore. It was prepared for a period of 15 years (1961-76) and covered an area of 500 sq. kilometre s. of which 220 sq. kilometres, was proposed for 'compact development' and designated as the Conurbation Area. The remaining 280 sq. kilometres outside the Conurbation Area, was earmarked as a green belt. The ODP remained in force until 1984. Well beyond its plan period. By this time it outlived its utility and the City had grown beyond the Conurbation Area and encroached the green belt. The delay in preparing a Comprehensive Development Plan to timely supersede the OOP resulted n large scale unauthorised development. MORPHOLOGY
    • BDA  To counter multiplicity of authority Government constituted the Bangalore Development Authority (BDA), in 1976 under the statute of The Bangalore Development Authority Act, 1976 to amalgamate the duties of the Bangalore City Planning Authority and the City Improvement Trust Board and thereby combining the functions relating to plan preparation, enforcement and implementation under one agency.  Thus, the BDA became not only the Planning Authority for the Bangalore Metropolitan Area but also a development agency.  An early task of the BDA was to prepare the Comprehensive Development Plan (CDP), to supplant the outdated GOP. But, it took nearly eight years to prepare this Plan and have it approved by the State Government.  The CDP had a planning time horizon of 15 years (1986-2001) and a target population of 7.0 million. The designated planning area was extended from 500 sq. Kilometres to 1,279 sq. kilometres. BMRDA  In an attempt to deal with these new but burgeoning urban problems, the Government in 1985 constituted the Bangalore Metropolitan Region Development Authority (BMRDA) by an Act of Legislature. BBMP  BBMP was formed in 2007, by amalgamating the erstwhile Bangalore Mahanagara Palike (BMP), surrounding eight smaller urban local bodies and 110 villages.  BBMP now spans over an area of 800 sq km. 2013  In 2013, it is not surprising to see significant changes in the configuration of the city. The changes have been driven by the social and economic forces at work in Bangalore.  The growth of Bangalore as a city for employment has brought large scale migration and with it changes in land use patterns.  An obvious change in the city’s land use is the elimination of nearly all water bodies. Dharmambudi tank is the present day’s Kempegowda (Majestic) bus stand where as Sampangi tank is the Kanteerava stadium.  Numerous lakes have been drained or left to die for use as residential or industrial areas. Agricultural land has been converted into apartment and shopping complexes. MORPHOLOGY
    • Area of Bangalore Source of water High ground:  The waters coming off the two sides of Bangalore ridge flow initially through a series of tanks.  They eventually reach the Bay of Bengal.  In the late 1800s, this divide was overcome at a place called High Ground.

    • Bangalore city has developed spatially in a concentric manner:  The first zone  comprises the erstwhile city corporation area of 226 sq. km.  The second zone  includes the areas of the former 8 neighboring municipal councils and 111 villages, which together form the peri-urban areas and are now incorporated into the Greater Bangalore City Corporation.  The third zone  includes other villages extending up to the Bangalore Metropolitan Area limits as proposed by BDA. ZONING
    • There are five major zones that are observed in the present land usage pattern: Zone 1 The core area consists of traditional business areas, administrative centre and the central Business district. Zone 2 The peri-central area, has old residential areas planned around the core area. Zone 3 The Recent extensions of the city (past 3–5 years) flanking both sides of the outer ring road. Zone 4 The new layouts, in the periphery of the city, with small vacant lands & agricultural lands. Zone 5 The Green belt and agricultural area, in the city’s outskirts including small villages.

    • • The picture shows wind roses for Bangalore for the respective months of a year. WIND DATA N – total no. of observations C – no. of calms as percentage of the total
    • • The picture shows the sun path at the proposed site. • The sun paths are different due to factors such as:  Location – local latitude  Rising and setting position – based on the time of the year  Duration of the day and night Analysis  90% of wind direction is from the northwest direction  Fenestration:  Should be minimal on the southeastern side to block the harsh sun.  Should be sufficiently placed on the northwestern side to allow the winds inside the building and on the northern side to benefit from the glare free natural lighting.  Water bodies, if any, should be placed in the direction of the wind, which adds humidity to the dry atmosphere. SUN PATH
    • Topography:  An average elevation of 920m above mean sea level.  The topography of the site is flat with negligible contours.  Seismic activity  Classified as a part of the seismic zone II (a stable zone) Drainage:  Dasarahalli tank is located to the west of the site.  There are no other major water bodies in and around the site.  Drainage pattern  The drainage of water is towards the south west direction of the site Vegetation:  Primarily in the form of large deciduous canopy and minority coconut trees. TOPOGRAPHY, VEGETATION AND DRAINAGE
    •  Greater Bangalore (77°37’19.54’’ E and 12°59’09.76’’ N) is the principal administrative, cultural, commercial, industrial, and knowledge capital of the state of Karnataka with an area of 741 sq. km.  Morphology:  Bangalore has grown spatially more than ten times since 1949 (69 square kilometers) and is a part of both the Bangalore urban and rural districts.  Now, Bangalore is the fifth largest metropolis in India currently with a population of about 7 million.  Climate:  The mean annual total rainfall is about 880 mm with about 60 rainy days a year over the last ten years.  The summer temperature ranges from 18° C – 38° C, while the winter temperature ranges from 12° C – 25° C.  Bangalore is located at an altitude of 920 metres above mean sea level.  Thus, Bangalore enjoys a salubrious climate all round the year.  Topography and Drainage:  There are four delineating watersheds, viz. Hebbal, Koramangala, Challaghatta and Vrishabhavathi watersheds  The undulating terrain in the region has facilitated creation of a large number of tanks providing for the traditional uses of irrigation, drinking, fishing and washing.  This led to Bangalore having hundreds of such water bodies through the centuries.  Even in early second half of 20th century, in 1961, the number of lakes and tanks in the city stood at 262 (and spatial extent of Bangalore was 112 sq km). However, number of lakes and tanks in 1985 was 81 (and spatial extent of Bangalore was 161 sq km). SUMMARY
