Residential Rain Garden Takes Shape

A City resident transforms her front yard from grass to a rain garden full of native plants, that now capture all of the runoff from her front roof, porch roof, and sidewalk. The installation was completed by Susquehanna EcoDesign who described the plant selection as Wildscaping, a native wildlife garden that is pollinator friendly.

Many residents in the City have small postage stamp front planting or grass areas and this application is ideal for those who want more color and less mowing.  In this case the yard had a slight slope to the sidewalk so a small retaining wall was installed to hold the soil and level the garden.

Grass was removed to create the rain garden area and stones were added to support the far end of the garden where the new soil was placed.  The square footage of the area excavated was calculated to insure it will capture at least 1″ of run-off from the front of the house.  Overflow water from the rain garden is piped back into the combined sewer pipe as shown below.

Rain Gardens along W James St

As construction begins along Mulberry and West James Streets you should notice an immediate (and green) difference when you reach a corner crosswalk.  Beginning last fall City contractors started to install these vegetated curb extensions / rain gardens and this spring they were planted.  West James Street will soon be paved and Mulberry Street will begin its conversion to a complete green street soon after.  The first of its kind in Lancaster City, Mulberry Street will go back to a two way street (instead of one) and will boast bike lanes, permeable paving, vegetated curb extensions / rain gardens, newly planted trees and much more.

Contractor Workshop

The City of Lancaster, in cooperation with the Lancaster County Conservancy and the Lancaster County Conservation District will be offering a two-hour workshop for contractors to discuss the City’s green infrastructure program and the role small stormwater projects have in helping meet regulatory requirements.

During this workshop, the City will provide an overview of the stormwater management program and review recent updates to the City Stormwater Management Ordinance and Small Stormwater Project Permit Application.

The slides from the presentation can be found here

Curb Side Gardens

A number of Curbside gardens have popped up surrounding other green infrastructure projects throughout Lancaster City.  They often extend from the curb or intersection, serving to both capture stormwater, while also slowing traffic and making these areas safer for pedestrians.

Lancaster is one of many City’s undertaking such projects.  Here is an article recently published in the New York Times New York Plants Curbside Gardens to Soak Up Storm-Water Runoff – NYTimes com.

Impact of a Drop of Water

Impact of water drops on the surface of granular particles

Abstract: When a granular material is impacted by a sphere, its surface deforms like a liquid yet it preserves a circular crater like a solid. Although the mechanism of granular impact cratering by solid spheres is well understood, our knowledge on granular impact cratering by liquid drops is still very limited. Using high-speed photography, we investigate liquid-drop impact dynamics on granular media. Surprisingly, we find that granular impact cratering by liquid drops follows the same energy scaling as that of asteroid impact cratering. Inspired by this similarity, we develop a simple model that quantitatively describes the observed crater morphologies. Our study sheds light on the mechanisms governing raindrop impacts on granular surfaces and reveals an interesting analogy between familiar phenomena of raining and catastrophic asteroid strikes.
