Since July, communities in Jackson, Mississippi have been under rolling boil notices, and heavy rains have left over 150,000 without clean water since for over a week. Extreme monsoons continue to devastate Pakistan, displacing and killing hundreds of thousands. The West Coast and much of the United States is experiencing a dangerous heat wave with temperatures reaching uncharacteristic triple digits. As summer (supposedly) draws to a close this Labor Day weekend, the reality of climate change continues to threaten our water security, critical infrastructure, and communities around the globe. Lotus applauds those who are fighting for environmental justice, including the human right to clean water, for all. Learn how you can help at https://earthjustice.org/about/contact

Happy St Patty's Day! In the spirit of celebrating the glory of all things green, here are some of Lotus' favorite green stormwater infrastructure (GSI) projects in San Francisco. Since 2007, Lotus has been working closely with to develop and grow the City's GSI programs including providing engineering planning, design, and monitoring support for pilot projects in each of San Francisco's 8 watersheds as well as various GSI grant programs. Rain gardens and green streets not only help slow and treat stormwater, but can recharge groundwater, enhance community space, improve street safety, promote biodiversity, and provide a host of additional benefits...as well as add a nice pop of green to our urban landscapes.

In celebration of Black History Month, Lotus is highlighting contributions and achievements past and present of Black Americans to civil engineering, water innovation, and environmental justice. Archie Alexander was an accomplished civil engineer, architect, and early industry trailblazer, becoming the first Black student (and athlete!) to graduate from the University of Iowa's engineering program in 1912. Shortly after earning his degree, the enterprising young 26-yr-old struck out in 1914 to form his own engineering firm. Alexander overcame racial barriers, building a reputation for impeccable work and winning hundreds of projects nationwide. Notable work included a multimillion-dollar sewage treatment plant (1929) in Michigan and many bridges, such as the Kutz Memorial Bridge & Seawall (1943), built by an integrated crew in DC’s Tidal Basin as part of the city’s early engineered solution for tidal flooding from the Potomac River.

Alexander also advocated for equal rights and opportunities, leading the Des Moines chapter of the NCAAP and establishing generous scholarship funds at his alma mater, Howard University, and Tuskegee Institute for future generations of Black engineers.

Happy World Wetlands Day! Lotus celebrates the many benefits that wetlands bring to water systems and the communities around them. Wetlands provide flood protection by dampening storm surges, with roots and vegetation helping to slow and distribute flows across the floodplain, allowing time for water to infiltrate. Wetlands are also highly productive and can nourish ecosystems. The circulating waters distribute nutrients to support wildlife and a complex food web. Wetlands also help improve water quality by trapping + filtering sediment, breaking down pollutants through root absorption, and managing excess nutrients.
🌿💧🐟🩺
Wetlands are also a powerful stormwater management and flood resilience tool. As part of the New Territories North Strategy Growth Area Plan in Hong Kong, Lotus incorporated wetlands as a vital component for climate change adaptation and protecting native ecology within the planned development. The plan proposes a new urban development while preserving and sustaining the rich ecological habitats in the area, including mangroves, wetlands, mudflats, fishponds, grasslands, and shrublands. With a proposed floodable, riverine corridor, the designed ecological zone will separate the urban development from the existing habitats while providing the wetland benefits of flood protection, water quality improvement, and ecosystem nourishment.

In honor of Native American Heritage Day, Lotus is highlighting the intersection of art, water, and the rich history of our Bay Area watersheds. Calling local artists and those with a meaningful connection to the Alameda Creek Watershed: the San Francisco Arts Commission is seeking wall-mounted artwork for the SFPUC’s new Alameda Creek Watershed Center Community Meeting Room to celebrate the Watershed’s native landscape.
🎨 🖌️ 🖼️ 📸
At 660 square miles, Alameda Creek Watershed is the Bay Area’s largest watershed, and is the ancestral homeland of the Ohlone, the eastern branch of the Ohlone peoples whose descendants collectively call themselves the Ohlone. The Ohlone called this area Síi Túupentak, or “Place of the Water Round House,” which was a major ancestral heritage mortuary and village. Today, the watershed is a vital part of the Hetch Hetchy Regional Water System in delivering drinking water to Bay Area residents and sustaining local wildlife.
💧 🏞️ 🍂 🌱 🐦💧
Located at the confluence of two creeks, Alameda Creek and Arroyo de la Laguna, the Alameda Creek Watershed Center is scheduled to open in Spring 2022 and will be an educational hub adjacent to the historic Sunol Water Temple. The Center intends to educate visitors on the history and heritage of the Muwekma Ohlone homelands, the natural history of the Alameda Creek Watershed, and the importance of water and how it’s managed by the Hetch Hetchy Regional Water System.

Lotus Water is honored to be part of the SFPUC’s Bioregional Habitat Restoration work, providing geospatial and field support for long-term asset and land management throughout our Bay Area watersheds, including the Alameda Creek Watershed.
🚰 🗺️📍📱 📐
Deadline for artwork submission is December 6, 2021. For more information, visit https://www.sfartscommission.org/find-opportunities/calls-for-artists/alameda-creek-watershed-center-2-dimensional-artwork-purchase.

Happy GIS Day! Geographic information systems are one of the many tools that Lotus uses to help our clients analyze + better understand their water resources, infrastructure, and the communities they serve. Maps have the power to reveal insightful spatial relationships + trends, by overlaying all kinds of data: topographic, ecological, social, political, built environment, etc…all of which can help decision makers identify critical needs + develop solutions, particularly for large-scale issues such as climate change.
💡🗺️🌊🌡️🌏⛈️
We took the opportunity to explore the patterns of San Francisco’s future flood impacts, starting with what was here before the city was built. Historically, SF was Yelamu Ohlone territory covered by lakes, creeks, marshes, + beaches. Today, most of those historic waters + eastern shoreline have been paved over by landfill, development,+ continued urbanization. However, as sea levels rise with climate change, nature is starting to reclaim parts of the city. High-emission scenarios predict about 9 feet(!) of total water level rise (7ft sea level rise + 2ft storm surge) for SF ( ). Rising seas could in turn drive up aquifer levels, causing additional flooding from surfacing groundwater ( ). On top of that, higher intensity rainfall is also becoming more frequent as the planet warms, with both inland stormwater flooding + storm surge compounding the effects of sea level rise flooding.
🚰🏗️⛑️🚧🤝🏼💰
Future seawater, groundwater, + stormwater flood risk closely follow the City’s valleys + historic waters, with the eastern Bay shoreline seeing the greatest impact. The area is home to critical city services, infrastructure (such as the Southeast Wastewater Treatment Plant), + many vulnerable community populations, including the Mission + Bayview districts. As highlighted by last week’s in Glasgow and the recently passed bipartisan bill, it is increasingly imperative that policymakers, planners, designers, + corporations begin investing in collaborative, long-term solutions to manage + protect our neighborhoods.

Happy ! We’re celebrating in the SF with the return of 🌧️☔ this week, with forecasts predicting record-setting precipitation for the region. Though this is still just a drop in the bucket for overcoming the current multi-year drought, Lotus is thrilled for the wet weather and used the opportunity to take a closer look at the role of water in our daily lives. We asked Lotus staff to keep a water diary, tracking water usage and observations for just a single day. Based on our (scientifically-sound 🤓) data collection, Lotus personal water usage came in @61 gallons per capita per day (gpcd), which is comparable to the residential average for the Bay area (64 gpcd), and is substantially less than the national average (82 gpcd). We can all lower water usage by installing water-efficient fixtures + appliances, in addition to making other conservation efforts at home: taking shorter showers, collecting rain + excess shower water for , eliminating car washes, and letting the yellow mellow 🤪🤫🤷🏽

Overall, the exercise was an important reminder of just how much we rely on water AND how fortunate we are to have easy, abundant access at the turn of a faucet. 🚽 🚾 🚰 🚿 🛁💧
