Starting the Game: 1. Deal each player one goal card and three property cards. 2. Each turn a player must roll the dice. If the dice lands on odd number the player must draw from the chance card pile. 3. A player may choose to build or not to build on each turn, but must always have no more than three property cards in their hand. 4. Keep track of your points.

Adaptation Strategies 1: Rain Gardens

Adaptation Strategies 2: Tidal Marsh

Adaptation Strategies 3: Floating Houses

Planting greenery to absorb rainfall is an important tool for adapting to rising sea levels and more extreme storms. A network of rain gardens seeks to mimic a natural ecosystem and ends the scourge of sewerage overflows.

In addition to providing habitats for endangered species, tidal marshes provide numerous ecological services, including erosion control along the shoreline, and buffering from storm surges.

Floating houses are built to be situated in a water body and are designed to adapt to rising and falling water levels. Because floating houses adapt to rising water levels, they are very effective in dealing with floods.

Larkspur is a city in Marin County, California, United States, at an elevation of 43 feet (13 m).

As of the 2010 Census, the city's population was 11,926. Larkspur is located north of San Francisco near Mount Tamalpais.

The Concept of Mixed Land Use & Green Buffers Residential

Mixed land use enables a range of land uses including residential, commercial, and industrial to be co-located in an integrated way that supports sustainable forms of walking and cycling, and increases neighborhood amenity.

1. Near the port, the residential area and industrial area were close to each other without any safety barriers.

2. In land use planning, more programs are introduced to the port area, the diversity of land use is increasing.

Mixed Center

Green Space Commercial

3. Different programs should have overlaps in order to make the neighborhoods walkable and livable.

This area provides natural light. Facing the courtyard, people can read, communicate and enjoy delicious food at the same time.

Being with the light, trees and the air, people can feel the peace and quietness. It is an ideal space for young people to practice meditation.

Hanging out with friends and families in the yard of the hackerspace is a great way to communicate with others and get inspiration.

The regeneration project is a gathering place, bringing energy and laugh to old citizens. Also, the community will become a vibrant area for people to live in.

I believe that the renewal and transformation of rural architecture are built on the local style. This program should not only accommodate the original country life but also to meet the new requirements. In the limited building space, I hope to give users more possibilities to use. It is a small community activity center for local villagers, and an indoor activity place for parents and children tourists.

POETIC WISH TO THE SEA

Early Morning Lee's dad said goodbye to the family and went fishing.

Afternoon Lee and his mom prayed in the Mazu temple for family's safey.

Dusk They looked far into the sea and threw stone to express their wishes.

After Sunset The stones runs in a long way, leaving, at low tide , a long stretch of yellow sand.

Timeline of Fishing in Southeastern China

"In addtion to supporting my family, I have plenty of fish for trade and commerical. It is incredible!"

"It was hard for fishermen to support the whole family living in the fishing villages in the past 50 years. "

"The trap construction has become a landmark and unique landscape in my village!"

Before steamboat, people who lived in the southeast of China caught fish on their boats made from wood or bamboo.

Narrative

Then in construction, people built fish traps, including fishing weir, fishing nets, fyke nets and so on.

Over the past 50 years, fishing technology has advanced greatly, increasing the capacity to locate and catch fish.

Old constructions are abandoned and are transferred to ritual space intergrating into the landscape along the seacoast.

A Typical Fishing Village in Zhangzhou

While at the seaside, playing with rocks might be an instinctive behavior.

Instead of using big rocks to build fishing traps, pebbles and stones become symbols of wishes.

Over time, local fishermen and their families lived along the seaside generation by generation, and the gravel roads grew and crisscrossed. Their praying and throwing action is the symbol of family ties. Fisherman's Houses Temple

With more people's help, the ordered space extends to the sea.

With time going by, the landscape still grows, as if we are closer to fishermen in the distance.

Fisherman's Houses

There are many people depend on fishing for a living, and the action of praying and throwing pebbles into the sea to express families' longings for safe and sound, which forms a distinctive scenario.

Considering that this project is a new project, far from Hangzhou City, and has a high similarity with the location, development content and planned population of the case study (Liangzhu Culture Village), the proportion of Liangzhu Culture Village is taken as an important reference data. After 16 years of development, Liangzhu project has a residential rate of 60%, so it can be used as a reference data for the mature period of the project. "SAY HI" Town projects are of high quality, clear positioning, and have corresponding price advantages in real estate sales in the short term. They should be more attractive to customers.

URBAN VITALITY STUDY ON CHENGDU DOWNTOWN WITH SPATIAL DATA ANALYSIS [EXCERPT] Project Type Location Instructors Responsibilities

Step1: Methodology (with ArcGIS)

Research Project, Final thesis of bachelor's degree, March - May 2018 Chengdu Downtown Dr. Xu Xiwei Individual research; The full paper is available in my writing sample.

1. To Select the scope of the research and obtain basic information; 2. To Collect related Baidu POI data and Baidu Heatmap; 3. Data cleansing to detect and correct corrupt or inaccurate records; 4. Degree of aggregation of different POI: to process results of POI density analysis separately in ArcGIS; 5. Overlay analysis of all activities: to calculate all selected POI density (with a weighted average) in ArcGIS; 6. The relationship between commercial and business sites (POI density) and urban vitality: to compare the results of POI analysis with the Baidu Heatmap which displays the vitality of people in the city Step 2: POI Density Analysis

▲ This study explains the degree of importance of different types of facilities through research on relevant reference papers and review checklist in city planning field. By comparing and simulating the degree of importance with Yaahp (a software that provides model construction, calculation, and analysis for decision-making processes), I determine weights of POIs by fuzzy quantization with the overlay analysis. Then, I assign values to different POI facilities in the overlay analysis according to different weights. *Basemap from OSM

Step 3: Areas with Higher Distribution

▲ (1) CBD -- Chunxi Road Pedestrian Street;

(2) Dayuan International Center; (3) CBD -- Hongpailou;

▲ In this study, from the 13 categories of POI data obtained, the data of 8 types of commercial service facilities closely related to the behavioral vitality in the city were selected. Kernel density analysis was performed on each type of POI to obtain corresponding raster data and distribution density maps of commercial and business sites.

▲ In order to simplify the information and to group various categories of POI for the next step, I reclassified the values of the set of rasters to a common scale and grouped the values into ten specified intervals.

(4) Around Sichuan Gymnasium Station

(5) Residential Area -- Chadianzi Yumiao Road Community

Step 4: The Relationship Between Commercial and Business Sites and Urban Vitality

Comparing the results of Baidu Heatmap analysis with the results of POI density calculation, it is not difficult to find that the two are closely related. That is to say the more diverse the types of commercial and business facilities, the higher the density in space and the more intensive and dynamic the people are. 23

Shared Bikes and Urban Cycling

At weekends, I' like to do outdoor exercises such as riding bike with friends.
