Taguig City : 

Taguig City Moving Forward to a Premier Waterfront City By Grace Edralin-Servino In line with its plan & vision, we can improve the city through landscape interventions

Introduction : 

Introduction how to design landscape which reduce flood damage

Waterfronts in the World : 

Waterfronts in the World In many design of cities, they embrace water as centers of development

Laguna Lake : 

Laguna Lake largest inland body of water (RP) watershed spans 14 cities & 17 municipalities of Laguna, Rizal, Batangas, Cavite, Quezon, & MM located in the major growth corridor of the country. Surface Area: 900 km2 Average Depth: 2.5 m Maximum Depth: 20 m Average Volume: 2.25 - 3B m3 Ave. level increase: 0.28m/mo Retention Time: 8 months Shoreline: 285 km Watershed Population: 6 Million (NSO 2000) Biological Resources: Fish, mollusks, crustaceans, planktons, macrophytes In NCR, Laguna Lake is a large catchment basin for floodwater MANILA BAY LAGUNA LAKE

Laguna Lake : 

Laguna Lake huge waste sink from: households cropland areas Industries livestock poultry fishery no municipality with sewerage system Pollution from surface run-off polluted waters from Marikina & Pasig Rivers 4/15 rivers: highly polluted in BOD 15 rivers: high fecal contamination 2.7 million people affected Also serves as a huge waste sink MANILA BAY LAGUNA LAKE

Metro Manila Flood Control : 

MM flood control measures are not working properly,blocked by squatters & w/ limited volume Ondoy’s vs. Manggahan floodwater 3,300 m3/sec >2,400 m3/ sec Metro Manila Flood Control Napindan Flood Control Station Manggahan Floodway Pasig River Napindan Channel

Rivers in Taguig : 

Built-up areas pollute the rivers resulting to high coliform levels NAPINDAN RIVER TAGUIG RIVER Rivers in Taguig

Slide 8: 

DRY SEASON: NOV – APR WET SEASON: MAY - OCT MAX RAINFALL: 2,000 MM PEAK: 400 MM (AUG) LOW: 4 MM (MAR) LAGUNA DE BAY Taguig land area collects large volume of water 2nd largest city in MM Land area x amount of rainfall 47.88km2 x .002 = 95.76 ≈ 100 km3 (large volume of water)

Flooding in Taguig : 

Flooding in Taguig Over half of the city within the flood zone

Causes of Flooding : 

red areas in Taguig get flooded for months SPILL FROM LAGUNA LAKE & PASIG RIVER LOW ELEVATION POOR SOIL PERMEABILITY ALTERED NATURAL DRAINAGE WATER RUNOFF FROM LARGE GEOGRAPHICAL AREA RECENT DEVELOPMENTS Causes of Flooding

Methodology : 

Methodology To identify & address the problem, study was based on SWOT, plans, images, case studies SITUATIONAL, SWOT ANALYSIS CLUP, LLDA RESOLUTIONS, STRATEGIC CONCEPT PLANS CASE STUDIES SATELLITE IMAGES, SITE VISITS, INTERVIEWS PROPOSED VISION, CONCEPTS, DESIGN GUIDELINES, DESIGN FEATURES

Location : 

LAGUNA DE BAY C-5 C-6 CAINTA PASIG TAYTAY PARANAQUE MAKATI EDSA SOUTH LUZON EXPRESSWAY PASAY PATEROS MANDALUYONG TAGUIG CITY MUNTINLUPA Location Taguig City is surrounded bymajor cities in MM, bisected by major roads

Slide 13: 

Early settlements grew along the lake & rivers providing water, protection and travel

Taga-giik : 

Taga-giik Early settlers were called “Taga-giik” or palaytreshers so place was called later as Taguig

Barangays : 

Barangays STA. ANA WAWA BAMBANG TUKTUKAN USUSAN IBAYO-TIPAS PALINGON LIGID-TIPAS CALZADA NAPINDAN HAGUNOY LOWER BICUTAN BAGUMBAYAN WESTERN BICUTAN MAHARLIKA VILLAGE SIGNAL VILLAGE FORT BONIFACIO Names given to most barangays or towns were influenced by water

Strengths : 

Strengths From an agricultural & fishing community along the Bay

Strengths : 

Strengths now an important residential and industrial suburb of Manila

Strengths : 

Strengths construction of C-5 made the city more accessible

Strengths : 

Strengths Fort BonifacioDevt. generating more income paved for its cityhood

Weaknesses : 

But there is still a need to improve utilities Power generation Waste management Flood control Housing provision Weaknesses Transportation system water supply & waterways

Housing : 

Housing Taguig population is swelling at tremendous rate demanding housing & other needs

Transportation System : 

With narrow streets & limited access and few links to major roads Transportation System

Water, Sewage & Solid Waste Management : 

Water, Sewage & Solid Waste Management Suffers from inadequate water supply, sewage treatment & garbage collection systems

Opportunities : 

Opportunities Major components for developments: water resources, open spaces & new highway (C-6)

Threats : 

Threats Unless govt, developers & community will participate, projects may not be achievable

Vision & Mission : 

Vision & Mission to be a PREMIER CITY Quality environment People oriented public services Economic opportunities Its vision is to be a premier city

Vision & Mission : 

Vision & Mission to be an ENVIRONMENTALLY-SUSTAINABLE CITY Development Policies strategies Programs & projects and to be an environmentally-sustainable city

Slide 28: 

Based on MM Land Use, land devoted to open spaces is about half its total area

Official Zoning Map : 

Official Zoning Map but in its official zoning map, there are few designated open spaces (green colored)

Laguna de Bay Master Plan : 

Laguna de Bay Master Plan in this masterplan, Taguig is zoned for urban & industrial uses relating to the Lake

Laguna Lake Development Authority : 

Laguna Lake Development Authority Limit use of lands below an elevation: 12.5 m Include 70% of Taguig mitigating factors: Flood control measures development in Taguig development contributions on “the regional scale” LLDA limits use of land below 12.5m which includes 70% of Taguig

Strategic Concept Plan : 

Strategic Concept Plan New land uses will arise out of areas secured by flood control system, in agricultural land, and the proposed reclamation in Taguig’s Strategic Plan, new land uses can rise with flood control system

Strategic Concept Plan : 

Strategic Concept Plan recommends that some area (a strip of some 1000-1500m width) be reclaimed from the lake also in this plan, a reclamation from the lake is proposed

Land Use : 

Land Use Residential areas will be mixed with open space Residential Areas - to provide middle class residential units, mixed with open space, retail & community facilities in every barangay

Land Use : 

Land Use commercial & mixed use areas will be concentrated in Old Taguig, FTI, & new waterfront Commercial & Mixed Use Areas will be concentrated in the Old Taguig area and the existing FTI location, & new waterfront oriented area

Increase Permeability : 

Increase Permeability use grass pavers on pathwalks, parking & driveways retain more grass-covered lawns Increase permeability using grass pavers or grass-covered lawns

Recommended Plants : 

Recommended Plants thrive along riparian areas useful for phytoremediation effective in water absorption help prevent erosion Attract animals and other life forms interesting form, color, texture, & appeal to the senses provide shade through their large canopy native to the place or with historical significance Background: Eucalyptus deglupta(bagras); Middle ground: Callistemon viminalis(bottlebrush); Foreground: Neomaricagracilis(walking iris) Use plant species for phytoremediation, water absorption, erosion control, biodiversity, etc.

Conclusion : 

Conclusion To design landscapes that prevent flood damage: Turn water from a hazardous element to a functional landscape feature Rivers must be dredged and easement cleared to keep water flowing Runoff must percolate easily with the use of SUDS Excess water will be contained in detention ponds for water treatment & reuse Flood plains must be conserved as green open spaces Any future development must integrate green & water systems on lowest portions to segregate floodwaters from built-up areas Optimize higher ground or small islands for mixed-use, high rise structures connected by skywalks or tunnels All green spaces including green roofs, sky gardens, green walls, wetlands on roofs will reduce runoff rate & volume Taguig’s waterfront development will become centers of recreation, landmarks with civic identity, plazas of social change, economic growth & core of environmental renewal.
