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.

Plum and Walnut Intersection wins another award

Stormwater Solutions has recognized the green infrastructure project located at the intersection Plum and E Walnut Street.  This is another award for a project that has been recognized for numerous innovations including traffic calming, pedestrian safety, stormwater capture, public art, and public / private partnership.  This location has become a gateway for people entering the City.  To read the article click here.


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

Attendees will learn how the stormwater permitting process works, review an application from a City property and learn the step-by-step process to obtaining your permits quickly and efficiently.

Note: Although the City cannot endorse specific contractors attendees to this workshop will be added to a workshop attendance list that may be provided to property owners upon request.

Central Market Streetscape Project

Work on the long-delayed and much-anticipated Lancaster Central Market streetscape project should start in April as reported by the Lancaster Newspapers.  For article click here.

The new streetscape project will include green infrastructure and a rainwater cistern !

Mulberry Art Studios

Upgrades completed this past fall at Mulberry Art Studios parking lot, accessed from West King Street, will allow infiltration of approximately 150,000 gallons of stormwater off of adjoining buildings, as well as sheet flow from the parking lot.

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.

Street Trees

2014 updates to Tree Planting in the City of Lancaster…Everything you ever wanted to know about trees and a whole lot more…

Trees Ordinance, Chapter 273 of the Code of the City of Lancaster

The City of Lancaster tree ordinance acknowledges the urban forest as a necessary part of the City’s infrastructure. This green infrastructure provides numerous crucial ecosystem services to the city including environmental (stormwater management, carbon sequestration and urban wildlife habitat), social (human health, healing, and quality of life), and economic (increased property values, increased business activity and decreased energy use). However, the increased creation of urban land over time, coupled with the challenges in adequately maintaining the urban forest and tree canopy has created the need to further protect and conserve this valuable City resource.

A copy of the Trees Ordinance can be found here.

Tree Manual: Regulations and Standards for Arborculture Work

The regulations of this Tree Manual are intended to reduce tree canopy loss and implement urban forest management improvements through requirements for the planting and transplanting of trees, the care and maintenance of existing trees, tree protection, and the preservation of trees within the City of Lancaster.

This Tree Manual is supplemental to Chapter 273, Trees, of the Code of the City of Lancaster and establishes minimum standards for the design of landscapes so as to improve the community aesthetically, economically and environmentally.
