The site is located in district 4, which was surrounded by Saigon river, Te and Ben Nghe canal, shaped as a triangle, also contiguous to district 1 in the North, district 2 in the East, district 7 in the South and district 6 in the West.

The surveyed area was located in a corner of district 4. A potential place to develop with an urban scale street going through ( Nguyen Tat Thanh street ) and an important domestic street is Ton That Thuyet street and many linkage routes. The is also a riverbank existing along the area that head to Te canal, a well-known area that was famous for the economic and commercial activities on both ground and the river.

Thanks to the convenient location, the surveyed area is one of the very first waterfront that attract people come to use then settlement.

It used to be one of the busiest and most crowded district in the old Saigon. The economic and commercial activities was developed strongly during the French colonial then last through American aggression till now.

The economic and commercial activities also led to the development of the society and cuture such as the rise of temples among the area.

The surveyed area was one of the last place to develop in district 4 due to the focus to district 1 and the late apperance of Te canal that bring the human come to the area.

County flat terrain, topographic slope of less than 0.1% but lower valley. The average altitude is 1,20m while the lowest elevation of the area was 0.3 m ( no mentioning to the canal) and highest altitude area is part of ward 6 (2.0m) . 2/3 county area natural area located below the historical peak intensity 1,60m afternoon (November 2011) in which the largest affected area was the riverbank.

Geomorphological characteristics (or form) of district 4 is being surrounded by Saigon river, Ben nghe canal and Te canal that the connection between inside and outside of the district was mainly by using bridges.

Figure ground The morphology map showed that there are three main street systems currently existing in the area.

The first is an urban scale street going through in the north-east is nguyen tat thanh street that connects directly district 7 and district 1. the nguyen that thanh street is also an External route of the area that bring many opportunities in developing and convinience in accessibilities for the area.

Secondly is a very important domestic route in the south was ton that thuyet street in the south that going along the length of whole district 4 while another domestic street is Nguyen Than Hien street that is the linkage between nguyen tat thanh street and ton that thuyet.

The last was the inner streets, the alleys. as the map described, the alleys system of the area has a strong interaction that there was lack of dead alleys.

The building density in a neighborhood was too high that lead to lack of open space inside the residential area.

Public/private gradient

1. Traffic density is proportional to the hierarchy of streets 2. Ton That Thuyet St. observes the busiest traffic of trucks within the day especially at night-time as: - This is the major ring route providing permeable circulation for good/product transporting from D4 to other areas and vice versa.

- The chain of warehouses where trucks get in and out all day is located along the street.

3. The difference between day-time and night-time traffic density shows the traffic participants from outside areas. Wide alleys and narrow alley’s users are mainly the locals.

Housing typologies Generally, the housing storey and status patterns are rather harmonious, which partly reflects the locals’ quality of life and social status.

Lighting system

Road quality

Green space

On main streets: acceptable quality In alleys: lacks of lighting and undersized power lines.

Dark areas are potential for social crisis to strongly develop

Due to the upgrade road project, almost the road is good-quality. The sidewalk are encroached because economic activities of local people.

Green space placed on one area, but far away from residential and hard to access.

Ground level

Flood map

Environment quality

All alleys are risen up to 50cm above the street surface to reduce flooding due to rainfall and tide.

(1) observes the most severe flood coming from both reasons mainly because this area’s ground level is lower than (2)(3) and of poor drainage system

However, this leads to inconvenience for local’s daily life especially when moving in and out of their house and during emergency

There are only transport noise and garbage on Ton That Thuyet & Doan Van Bo (the informal market) street, other areas are clean and unpolluted

(3)’s reason of flooding is poor drainage system+ water pouring down from (2) which has higher ground level 9

Quality of life

Vulnerability

(1) Using the best urban infrastructure because the main streets nearby and well-accessible within the site.

(4) Less attention in renovation and difficulty in movement due to narrow and dead-end alleys.

Vulnerbility: Social evils happen often in alley. Quality of life is normal but not sustainable, easily affected by external factors.

1. General information

2. Along the canal bank

- Location: along Tran Xuan Soan St. (Dist. 7) and Ton That Thuyet St. (Dist. 4)

D. Warehouses & companies: 90% of these are not related to maritime function and 50% is recently established (eg: discard storage, industrial waste processor, building construction etc.)

- Width: 110m in average

E. Slums: degrading and not having any cultural and historical value.

- Depth: 13m in average

F. Khanh Hoi B elementary school: recently established

- Average flow: 54m3/s

3. Selection of site’s cultural and historical significance

- Hydrographical regime depends on:

A. Joss house: historically adhered to the area’s heyday, evoking the up-to-quay down-to-boat culture (since 1930s)

. Tide : highest 1,6m 0.3m (Jun-Jul)

(Oct-Nov),lowest

. Rainfall highest Jun-Oct, lowest Nov-May

B. Hong Ngoc Phu Quoc Trading and Waterway transportation: busy maritimez activities and area’s waterway landmark (since 1950s) C. Khanh Hoi Thread Enterprise: productive & widely influencing within the area’s economy (since 1994) 11

1. Economic axes The survey site is covered with 4 main economic axes: (1) Ton That Thuyet St. (2) Nguyen Tat Thanh St. (3) Nguyen Than Hien St. (4) Doan Van Bo St. (1) = industrial warehouses + heavy daily transportation (3)(4) = service and retail (small-scaled shops, stores and market etc.) located on busy but small streets (2) = (1) + (3)(4): small-scaled economy but located on one of the city’s heaviest traffic route

2. Social activities 1. On weekend, people gather at alleys & culs-de-sac where they feel convenience and familiar participating in social activities 2. Social activity density peaks at weekends (by time), and at Doan Van Bo St. and Nguyen Than Hien St. (by place), which is the 2 main economic routes of the survey site since economic spots and community hubs have a close relationship. These are non-designed activities.

3. Social interaction is weakest at night (by time) and at parks (by place) mainly because of the area’s poor lighting system at night and poor accessibility.

General trend: crowded non-designed activities and quiet designed activities

3. Relation ships between social and economic activities Locals tend to stick to Nguyen Than Hien St. and Doan Van Bo St. to participating in social activities (mainly chatting while having a drink or eating) which is formed from economic spots, because these places are accessible, convenience and familiar to human scale 12

Strength

Weakness

- Strategic location: 1. Waterfront 2.

District’s junction

- Weak connection between physical space, society and economy

- Good connection within the city (in future context)

- Outdated economy’s theme and urban infrastructure cannot catch up with modern context

- Significant cultural and historical background

- Lack of identity

Opportunities

Threats

- Potential future planning projects of the neighborhood itself and surrounding areas

- Dull identity if there wouldn’t be any overall and noticeable changing to keep up with modern context and the area’s growing pace.

- Regenerating identity in the past based on historical theme

- Competition from other developing neighborhood areas ( district 1,2, 7 ) beside being attached investor’s attachment

Technique infrastructure’s improvement owing to new project’s investment

-Challenge about Management of Population and investment in the near future

The concept is to create a new district as the sample of a compact city with the full of public facilities in a walkable radius. Also push up the potential of the surveyed area by re-connecting waterfront and land inside while zoning the different developing axes by functions as commercial, service or improve current living quality.

REUNITE AREA WITH WATERFRONT

CREATE CONTINUOS ACCESSIBLE WAY TO WATERFRONT

RECOGNIZE UNIQUE IDENTITY OF WATERFRONT’S DISTRICT

CREATE A DYNAMIC COMMERCIAL STREET

The proposed landuse plan divided the landuse into 2 main elements icluded Neighborhood land and Non-Neighborhood land. There will be no industial land in the future due to the development of whole district, greenspace and public space wil be raised and replace for the old industrial land to change the apperance and function of the area. The separating greenery will be placed along the river to reserved the land
