1.3 Scopc and Liinitatioln of the EIS study Public Disclosure Authorized
'file project involves wicicning or tlie existing two-lane road from Bacolod Cily to Sail Enriquc town proper. Thc BIA study focuses on the entire stretch of tlie road exccpt in areas wl~cretl~ere are existing ongoing works under tlie Regular Infrastructure Projects of tlie Bago and Bacolod City District Ellgineering Orfices. The stitdy also talces into consideration the social and pllysical impacts of the project specifically on affectcd Saniilics and structures due to widening.
1.4 Project Description and Scope of Work
'The project involves widening oftlie existing two-lane road into four-lane road (Portland Concretc Cemcn~Pavement or Asphalt Concrete Pavement). Total length of ll~cproject t- Public Disclosure Authorized road is 35.10 ltm. slarling at Jtrn 4 500 at the Bacolod Airport and ends at I

1.5 Brief Description of Baseline Enviro~l~ne~ltalConditioll
The Bacolod - lcabanltalan Road project, in particular the Bacolod - San Enriquc Sectioc starts at the terninus of Araneta Street right after the airport exit gate and onwards passing Barangay Sumag (part of Bacolod City), Bago City and the Municipalities of I'~~lupanclan,Valladolid and terriiiriates at San Enrique. Entire stretch of the road is characterized as flat to rolling in some areas. Prominent in these areas are trees and other perennials on both sides orthe road. Rich agricultural lands are also visible in the area.
'I'he project road is connccted with the Valleher~noso- Sari Enriq~~ecross lsland Link, which fiunctions as an interprovincial road ror the Negros lsland provinces. It also fornls past of tlie Bacolod South Road, which is classified as North - South bacltbone of the country's arterial road network.
Since the project involves widening, it is expected that there will be minimal displacement or structures and other perennials, substantial trees to be cut and tc~nporary loss of vegetative cover due to road cut design.
'I'hc existing road is in good to moderate co~lditio~iand ~nostlyin flat terrain. l'he traffic co~iditionof the area is now becoming a problc~iland it is expected that traffic situation will aggravate in tlic near future.

It is of interest to dcscribe tlie main socio-ccono~nicfeatures of the population rnost directly affected by this part of tlic transport. Ilence, ~iiostOF the discussio~ison this chapter will be 011 a micro basis. 4.2 PHYSICAL ENVIRONMENT 4.2.1 Regional Setting llie Bacolod-l 4.2.2 Topography Topography fro111 Uacolod-Kabankalan is relatively Plat and becomes gently sloping to rolling as the road moves eastwards. The road lies within the range of 100 m to 260 111 above sea level as reckoned from the NAMRIA map. From Bacolod City terrain is alniost flat to rolling up to the Municipality of San Enrique. Slopes are Very gentle. Contour witl~inthe influence area ranges fro111 90 In to 140 In elevation. The existing Asphalt road alignments traverse ~iiountainousterrain up to I 4.2.3 Climate Climate is pre-dominantly warm, with abundant of rainfall and gentle winds cold fro111June to December, dry during the montlis of January to May. Negros Occidental has two pronounced seasons, the wet and dry. The dry season is from late December to early parts of May for northern Negros and fro111 November to May for soutliern Negros Occidental. For the northern part of tlie province,tlie rainy seasons start in June, reaches its peak in September and tapers off towards the early part of December. For southern Negros Occidental, the rainy season begins in Julie, attains its peak in August and levels off towards the dry season. The northern monsoon prevails during the dry season while it is the southwest monsoon that dominates during tlie rainy season. In terms of agro-climatic zones, the province can be divided into four (4), namely: DI'Wl-I-E~iviron~i~e~italand Social Services Oflice 4 BACOLOD - KABANKALAN ROAD ( Bacolod - San Enrique Section) 1. Zone A: this includes Talisay, Silay, E.U. Magalona, Victorias, Manapla, parts of Cadiz City and Sagay, Escalante, Toboso, and parts oT Calatrava. 'This is a inoderately high rainfall area due to its geographic position, which is easily affectcd by thc l~orthcastand soiitl~castIIIOIISO~IIS. 'The dry scason is not distinct and lasts for only 2-3 months (March-May) and relatively wet for the rest of the ycar. Thc crop growing period spans from 8-9 months. T~LIS,2-3 croppings can be donc in a strictly observed time schedule. 2. Zonc B: this zonc covers parts of San Carlos City, parts of Salvador Bencdicto,parts of 1-limamaylan, parts of ICabanltalan, and Candoni, sipalay, I-Iinoba-an, Bago city Pulupandan, Vallladolid, San Enriquc, La Carlota city, La Castellana, Moises Padilla, Pontevcdra, tlinigaran, Isabela, Binalbagan, l log ancl Cauyan. These areas have a distinct dry and wet season. The dry season lasts about 6 nloilths (late December to May). Somc rainfall occurs especially in Dece~nberto February due to the prevailing northeast n1onsoon. The Icngth of the crop growing period is 5-6 months. Mean annual rainfall is 1508 mm -2692 mm. 3. Zone C: This includcs parts of San Carlos City, Parts of Calatrava, Bacolod City, Murcia, and parts of Salvador Benedicto. This is a tra~lsitionzone between Zones A and B. There is no distinct dry and wet season but it is characterized by a relatively low annual rainfall (1336 111111- 1500mm). 4. Zone D: This covcrs the niountain range areas of Cadiz city, Sagay, Hi~llamaylan, ICabanltalan, Candoni, Sipalay and tlinoba-an. This is a high rainhll area (2100 ruin - 2877 mm) duc to induced cloud formation given the high elevation (500 M +) AND COOLER TEMPERA'1'URE. Temperature crops (cabbage, Baguio bcans, coffee, etc.) are grown abundantly throughout the year. Its rugged terrain. 4.2.4 Hydrology There arc six big rivers in the provincc nanlely: Danao, I-Ii~noga-an,Malogo, Bago, Uinalbagan and Ilog. I-Iimoga-an River and its tributaries emanates fro111 the eastern slope of a chain of volcanic mountain ranges in the nortl~ernpall of negros Island. Danao River starts from the northeast cordillera and e~npticsinto Tanon Strait at Escalante. Malogo or Silay River originates fro111 the western slope or Mt. ICanlaon and drains inot Guimaras Strait. llog River is the largest in the province. Ti starts fro111 the soutl~easternportion of Mt. Kanla-on and empties into the Panay Gulf. Flood prone areas are usually found along the riverbanks of these big rivers. During the rainy season, thcy cause much damage especially to agricultural areas nearby that the governn~entwas prompted to construct flood control projects in these areas. 4.2.5 Geology and Geomorphology Negros Occidental and the rest of the region lies on a shelf, which has been formed by a ridge of volcanic tuff to the west. Fluvial deposits of sand, silt, gravel and clay III'WI-I-Gnviro~i~i~enlaland Social Services Office A BACOLOD - KABANICALAN ROAD ( Sacolod - Sat1 E~iriqucSection) bound the ridgc.

However, there are Sew industrial sources of air pollutants and the ambient concentrations of gaseous air pollutants are moderate. Adverse effects to air quality are confined only to those coming from equipment and dusts generated by earth excavations while expected noise sources are construction equipment such as jack hammers, bulldozers, back hoes, payloaders, graders, heavy truclts, generators and colnpressors during conslruction which are unavoidable, hence, strict implementations of the Environmental Management Plan and Environmental Monitoring Plan will be the gauge on this aspect.

Noisc levels at ilie proposed projcct site and the sorrounding area is moderate. Based on tlie present AADT projected to 2001, the range of' noise levels of tlic proposed projcct site is between 72 dBA to 90 dBA. 'he present level of noise and vibration williin the area from all types of vehicle is co~isideredtolerable. The populatio~iwithin tlie vicinity of the project area can be assumed to have adopted to the regular noise sources during construction activitics. Thc major soilrces of noise will include pile driving, heavy equipme~itoperations, and duliil~trucks hauling materials. Thc existing vegetations in the area will serve as buffer to additional noise during constri~ction. Upori co~iipletionof the proposed project traffic will be improved, resulting to air and noise quality improvement. 4.3 BlOLOClCAL ENVIRONMENT 4.3.1 Terrestrial Flora and S'auni~ Flora The different vegetation identilied within the project site and its i~ilnlediatevicinities include grasses, herbs, vines, shrubs, palms and trees.
