Urban natural areas provide much more than beautiful scenery. They support wildlife, improve water quality, moderate temperatures, and create spaces where people can restore both body and mind.

During this walk, Jennifer reflects on a simple practice, touching or leaning against a tree, and how these quiet moments can help reduce stress and encourage a sense of calm. While experiences vary from person to person, spending time in green spaces has been widely associated with improved mental well-being and a greater sense of connection to the natural world.

Sometimes the greatest value of urban nature isn’t something we measure, it’s something we feel.

Their leaves intercept rainfall, helping reduce the amount of water reaching the ground during storm events. Their roots stabilize soils, improve infiltration, and contribute to healthier watersheds, while their canopies provide shade that helps reduce urban heat.

Beyond these environmental benefits, trees improve air quality, support wildlife habitat, and make neighborhoods more comfortable places to live and explore.

Projects like these show that restoration is not simply about planting vegetation. It is about creating resilient systems that support biodiversity, improve water resources, and provide lasting community benefits.

Research continues to explore how trees may share resources and communicate through underground fungal networks and interconnected root systems. While scientists are still learning about these relationships, the concept highlights just how interconnected natural ecosystems can be.

Whether in forests or urban parks, healthy tree communities remind us that resilience often depends on connections that aren’t immediately visible.

Most of us experience rainy days by looking for shelter, but stepping outside offers a unique opportunity to see how streets, landscapes, and stormwater infrastructure actually perform. What may seem like an ordinary walk quickly becomes a lesson in hydrology, engineering, and the natural water cycle.

 Watch the Field Observation

These flow paths provide valuable information about how stormwater behaves. They show where water collects, how quickly it moves, and whether sediment or other pollutants are being transported away from a site.

Observing these patterns during a storm helps engineers, scientists, and property owners better understand how the landscape responds under real conditions.

Even on relatively small construction sites, appropriate erosion and sediment control practices are important to help prevent sediment-laden runoff from leaving the site and affecting downstream water quality.

Simple measures can make a significant difference in reducing erosion, protecting nearby stormwater systems, and maintaining healthier waterways during construction activities.

Simple measures can make a significant difference in protecting downstream water quality.

In this case, the muddy runoff appeared to trace a route from the construction area toward the street. These observations provide immediate feedback about how well—or how poorly—stormwater is being managed.

Field observations like this often reveal opportunities to improve erosion control before sediment reaches storm drains or nearby waterways.

The next time you find yourself walking during a storm, take a moment to observe where the water flows and what it carries with it. Those small observations often reveal the larger systems working around us, and remind us why thoughtful planning, proper maintenance, and responsible sediment control are essential for protecting water quality.

Most of the infrastructure that protects our water resources is hidden beneath our feet. Underground pipes, storm drains, and utility networks quietly move water through our communities with little notice from the people who benefit from them every day.

Green Streets offer something different. By bringing stormwater management above ground, they transform essential infrastructure into visible, educational features that help people better understand how cities can work with nature to improve water quality.

 Watch the Field Observation

Infrastructure You Can Actually See

One of the most striking features of Portland’s Green Streets is that the stormwater infrastructure isn’t hidden underground. Instead, a series of landscaped planters runs alongside the street, allowing anyone walking by to observe how runoff is managed.

Making infrastructure visible encourages curiosity. Rather than seeing only pavement and curbs, pedestrians can recognize that these landscapes are actively collecting, slowing, and treating stormwater before it enters nearby waterways.

Small Design Features with Important Jobs

Looking more closely reveals several thoughtful engineering details.

Beehive inlets are designed to reduce the likelihood of leaves and debris blocking drainage. Reinforced curb cuts guide runoff safely into each planter, while the generous depth of the planting beds provides temporary storage during storm events.

Although these features may appear simple, they represent careful planning that balances hydraulic performance, maintenance requirements, and long-term durability.

Slowing Water Protects Water Quality

Some of the planters include small rock check dams that slow the movement of stormwater as it travels through the system.

Reducing water velocity helps minimize erosion while allowing more time for infiltration and filtration. Instead of rushing downstream, stormwater moves more gradually through the landscape, giving soils and vegetation an opportunity to remove pollutants before the water reaches nearby waterways.

These are small design elements, but they play an important role in improving the overall performance of the system.

Watearth is leading the Mills Tower Drainage Feasibility Study for the City of Rancho Cordova The study addresses persistent flooding across a 152-acre drainage area with constrained pump station capacity.

Over the course of the project, Watearth has reviewed the City’s Master Plan, FEMA documentation, topographic and soils data, and hydrologic and hydraulic models. Initial site visits and a kickoff meeting helped validate desktop findings and identify opportunities for flood mitigation, including detention basins at White Rock Elementary School and Community Park, as well as distributed low impact development (LID) features.

Simulations for 10-year and 100-year storm events informed the performance evaluation of alternatives. The team has produced 10% concept layouts that integrate flood control, water quality, and recreational benefits, along with preliminary cost estimates and a comparative cost-benefit analysis. Deliverables include a detailed technical memorandum and ongoing virtual coordination with City staff.

At Watearth, one of the most critical decisions we make is selecting the right modeling approach for each project. Choosing the wrong model can lead to cost overruns, false confidence in designs, or missed flood risks that put communities in danger. The key is matching model complexity to the problem at hand.

When to Use 1D Modeling. One-dimensional models analyze flow along a single axis and are ideal for well-defined channels, culvert and bridge hydraulics, stream capacity analysis, and preliminary floodplain assessments. They’re efficient and can evaluate long reaches of river systems quickly, making them perfect for projects where cross-sectional data is sufficient. However, 1D models have limitations—they cannot capture lateral flow spreading or complex flow patterns that occur in wide floodplains or areas with multiple flow paths.

When 2D Modeling Makes Sense. When 1D assumptions break down, two-dimensional modeling becomes essential. We use 2D models for complex floodplain analysis with multiple flow paths, coastal and estuarine systems, dam breach scenarios, and urban flooding where streets become channels. While 1D shows you water elevation, 2D reveals where water actually goes and how fast it moves. This additional detail requires more extensive terrain data and greater computational resources, but for complex flow scenarios, the investment is necessary to capture the true hydraulic behavior.

The Role of Unsteady Flow Analysis. Unsteady flow modeling adds the time dimension to either 1D or 2D models, tracking how conditions evolve rather than assuming equilibrium. This approach is critical for flood routing and reservoir operations, storm surge prediction, dam failure studies, and any scenario where timing drives risk. We recently modeled Harris Reservoir where steady-state analysis showed adequate capacity, but unsteady modeling revealed conditions that could overwhelm outlet structures—an insight that drove critical design changes.

Hybrid Modeling in Action: Rubio Wash. Watearth supported the Rubio Wash subwatershed drainage study by delivering advanced hydrology and 1D/2D hydraulic modeling for one of Los Angeles’s most critical flood control corridors. The project combined detailed GIS-based storm drain inventories with MODRAT hydrology and XPSWMM modeling to identify system deficiencies under 10-, 25-, and 50-year storm events and guide future flood mitigation efforts.

Our Approach. We start by asking: What decisions will this analysis inform? What accuracy do stakeholders need? Sometimes the answer is hybrid—1D for an entire watershed with 2D focus on critical areas. There’s no universal “best” modeling approach. Our role is matching sophistication to project needs, delivering the insights you need for confident decisions without unnecessary complexity or cost.

Stormwater runoff from roads and parking lots is more than just water — it’s a vehicle for hydrocarbons and other pollutants from gas-powered cars that end up in our rivers, lakes, and oceans.

That’s where bioretention comes in.

As a leading stormwater best management practice (BMP), bioretention systems naturally filter pollutants through engineered soils and vegetation. These systems not only help manage runoff but also improve water quality, recharge groundwater, and enhance green spaces.
