Neighborhood Design on Steep Slopes

The talk is about Potrero HOPE SF Public Housing Master Plan and the Kirkham Project in San Francisco.  The Potrero HOPE SF Master Plan is a transformative project that will take recreate a 38 site with 606 public housing units that has been separated from the rest of the city  socially, economically and physically into a truly mixed-income and mixed-use community reintegrated into the urban fabric with up to 1,700 new homes including 606 public housing replacement units, additional affordable housing and market-rate development.  The Kirkham Project will transform an aging 86 unit, 6 acre property into a vibrant new community with up to 400 new units.  Both of these projects required a complete transformation of the existing conditions to create a place that is unique, vibrant and integrated into their urban environments and the neighborhoods around them.

 

Building Authenticity in the Landscape

Inspired by the existing modernist façade, the new courtyard at IBM Victoria Ward tower showcases a landscape expression of modern Hawaiian architectural motifs and powerful cultural history. The  historic IBM tower was designed by Vladimir Ossipoff—Hawaii’s quintessential modernist. The new landscape is a distilled expression of Hawaiian identity and serves as an introduction to a larger mixed-use master plan of over 60 acres in central Honolulu.

Native Grass Sod

_Picture1

Caltrans landscape architects partnered with academia and local business to develop native grass sod that is now available across California. Doug Brown was the landscape architect and project manager for the state-funded research project that led to the development of this brand new product. Before the study there wasn’t such a thing as native grass sod.

Golden grass-covered hills dotted with majestic oaks conjure images of iconic California landscapes. Preserving and establishing these kinds of native grasslands is a priority in creating and managing sustainable landscapes. Native grasses are especially sustainable, tolerating drought; requiring little irrigation, fertilizer, pesticides or herbicides; and demanding less mowing. Though they may be golden brown in the warm seasons, native grasses are truly the most ‘green’.

California’s harsh climate, lack of rain and invasive weeds make it difficult to establish native grasses using traditional seeding practices, whereas sod provides instant cover that can be established quickly.   Though deep-rooted native grasses seem like an unlikely candidate for sod harvesting, university laboratory studies and field-testing ultimately produced viable native grass sod mixes that were further refined and made commercially available by sod growers.

Creating a New Walking-Focused City District for 30,000 People

_Picture1

Raycom City, a new mixed-use district for Hefei, China, has a 3/4-mile-long public linear park flanked by stores and restaurants as its heart. The park and retail promenades provide a comfortable, convenient walking spine connecting the district’s residential, hotel and office towers, schools and amenities, an upcoming metro station and the surrounding city fabric.  To design the linear park and flanking promenades, Marco drew on Hefei’s identity as a river city with grand river parks to imbue the new district with a dynamic, high-performance outdoor environment.  With the rich mix of amenities and services provided in close walking distance within a beautiful and varied setting, the design strives to create an urban “Sculpture for Living” where people enjoy living locally for a higher than average percentage of their lives.

From Concept sketch to Construction How to hold on to design intent through engineering

Hyphae joined the design team for a 4-story multi-family mixed-use project in Santa Barabara, to take on a complex landscape over structure scope, engineering grading and drainage for greenroofs while integrating raised stormwater flow-through planters all set on podium.  Our design goals were to create a distinct design for several courtyard gardens, utilizing geometry, materiality, and plant habitats to create a clear distinction.  Overall approaches repeated the use of raised planters and vegetated screening to transform this unconnected structure to include network lush spaces for group gathering and personal reflection.

Brisbane Baylands Specific Plan

The Brisbane Baylands Specific Plan is an integrated new mixed use district planned for a Bayfront brownfield site sitting just south of the San Francisco City and County line.

The plan puts forth strategies for regaining ecological function lost through successive land “reclamation” initiatives and leveraging a confluence of existing and planned transit resources to create a vibrant new mixed use neighborhood at the northern edge of Brisbane and eastern edge of San Francisco’s Visitacion Valley.  The plan combines high density, transit-oriented housing with walkable retail, commercial office space and sites for new tech campuses, all within a framework of public open space that provides recreation and restoration of native ecologies.

Case Studies in Designing Affordable vs Market-rate Housing

Unknown

Comparing the landscape design of several of PGA’s recently completed housing projects.  The projects will vary from those built to serve the high-tech luxury market-rate to the professional class and affordable. Design and client expectations for each are widely different.  Chris will discuss key the differences in clients expectations and approaches.

Urban Forest of Africa | Johannesburg, Lagos & Cairo

By: Joe McBride
Slide37

The urban forests of Johannesburg, Lagos, and Cairo were surveyed to provide a data base for a comparison of their composition, structure, and condition.  Tree species diversity in these three urban forests was compared to the species diversity of trees in each biome in which the city occurred and to climatic parameters of each biome to measure the correlation between urban forest characteristics and the characteristics of the biomes.  Structure of the urban forest was examined in relation to historical precedents for urban design in each city.  Current problems of urban forest condition and management are discussed.

Delineating the Coast of Salalah Using Remote Sensing | Oman

By: Amna Alruheili

___Amna_1PastedGraphic-1

This study focuses on quantifying shoreline change through the use of remote sensing techniques, multi-temporal Landsat images, on the southern region of Oman’s coast (Dhofar, Salalah). The coastal shoreline of Dhofar Governance witnessed a major cyclone in 2002. As a result, morphological changes including the accretion and erosion of the coastline along Salalah took place.

In this study, coastline changes were researched using radiometrically and geometrically corrected multitemporal and multi-spectral data from Landsat Thematic Mapper (TM) dated 1984 and 1998, Landsat Enhanced Thematic Mapper Plus (ETM+) 2002, and Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) dated 2015. In the image processing steps, band rationing (B4/B2) and digitizing were used to carry out coastline extraction, and the Digital Shoreline Analysis System was used to calculate the rate of coastline changes. In some parts of the research area, remarkable coastline changes of more than 56.4 m withdrawal and -0.9 m/year erosion were observed in 2002.

If this is the situation for a development occurring within a park that is full of environmental researchers and park rangers, then what is the fate of other development that is occurring in absence of any environmental or climate change considerations.
