Did You KnowRadnor has over 57 miles of storm system pipe and over 1,500

inlets?

Some of this system is over 70 years old and beyond its

expected design life of 50 years.

Much of our infrastructure was installed prior to modern

codes and design guidance. As a result, portions of the

system are under-sized by todays standards.

Radnor sweeps 100 miles of Township streets 3 times per year?

Sweeping removes sediment and debris that would

otherwise discharge to the Gulph, Ithan and Little Darby

Creeks, helping to protect water quality.

Water quality practices count towards Radnors efforts to

comply with the Townships stormwater permit

requirements under the federal Clean Water Act.

Radnor collects leaves from residences across the Township?

Collecting leaves prevents them from blocking inlets and

from increasing nutrient loading, protecting the water

quality of local streams and maintaining system capacity.

Leaves are returned as mulch for use by residents andRadnors park system.

One out of every five stream miles in Radnor is impaired?

Of Radnors approximately 28 miles of stream, just over 6 m

have been designated as impaired by Pennsylvanias Departm

of Environmental Protection, including Gulph Creek and

upper reaches of Little Darby Creek.

What are Radnors Stormwater Challenges?Like many Pennsylvania communities, Radnor is faced with a rang

stormwater management challenges from increasing federal and sregulation to aging and undersized infrastructure. Depending

where you live in Radnor you may or may not have been dire

impacted by these events, but you likely know someone who

been. Some of the stormwater challenges the Township is curre

facing include:

Increased occurrence of flooding.

Infrastructure installed prior to modern standards, or not at al

Storm sewer which is beyond its expected design life.

$10M backlog of known stormwater-related capital improvem

projects and no dedicated capital budget to fund these project

Additional regulatory responsibilities for the Townships Muni

Separate Storm Sewer System (MS4) permit requirements uthe federal Clean Water Act.

Limited Public Works staff.

As the stormwater system has aged, funding for maintenance

rehabilitation has not kept pace. Since revenue to support

program comes from property taxes, stormwater must compete

other Township funding needs. In addition, only taxable prope

contribute to funding stormwater management. As a result, Rad

Township is evaluating an alternative approach to fund much-nee

enhancements to the Townships current stormwater program w

will allow better service Township-wide. An additional $2M

estimated to be needed on an annual basis to begin to address th

long-term challenges.

What is Stormwater?Stormwater is rainwater and melted snow that runs off streets, lawns, and other sites. When stormwater is absorbed into the ground,

filtered and ultimately replenishes aquifers or flows into streams and rivers. In developed areas, however, impervious surfaces such

pavement and roofs prevent precipitation from

naturally soaking into the ground. Instead, the water

runs rapidly into storm drains, sewer systems, and

drainage ditches and can cause:

Downstream flooding

Stream bank erosion

Reduced water quality

Habitat destruction

Changes in the flow rate of a stream

Infrastructure damage

Contaminated streams and rivers

How Can I Learn More?The stormwater program and proposed funding approach will b

discussed at the regular scheduled Board of Commissione

Meetings on:

August 12th

beginning at 7pm August 26

thbeginning at 7pm

In addition, the Radnor League of Women Voters is hosting

series of public information meetings on the following dates:

Thursday, August 29th

from 79pm

Thursday, September 12th

from 13pm & 79pm

These meetings will include a presentation on the stormwat

program funding study as well offer the public the opportunity

ask questions and provide comment on the proposed progra

and funding method.

You are invited to attend the public meetings and presentatio

at the Township Building at 301 Iven Avenue in Wayne.

All developed Single Family Residential (SFR) parcels will be assigned toone of the following Tiers based upon lot size and billed as follows:

*Note: 1 Acre = 43,560 square feet

All developed Non-Single Family Residential (NSFR) parcels will be billed

for stormwater at a rate of one billing unit per 1,500 square feet of impervi-ous area.

What Solutions are being Considered byRadnor? The Board of Commissioners appointed a Stormwater

Stakeholder Advisory Committee (SAC), made up of

citizens from across the community, to provide the

Township with input on developing an enhanced

stormwater program and evaluating a dedicated funding

approach. To begin to address Radnors stormwater challenges, the

proposed program would, on average, provide an

additional $1.2M for Capital Improvements, $550k for

Operation and Maintenance Activities and $120k for

Compliance and Asset Management related activities per

year.

The costs for enhanced stormwater services could be

distributed across the community by using a fee structure

based upon an analysis of impervious cover throughout the

Township. The rate structure initially recommended by the

SAC (see Table), would place single-family residential

properties into four tiers based upon lot size, with billing

units assigned based upon a sampling of impervious

surfaces within each tier. Non-single family residential

properties (such as commercial properties, institutions,

and apartment buildings) would be billed per 1,500 square

feet of impervious area on their parcel. Without a

dedicated fee, the Township need to raise taxes to address

stormwater problems.

The SAC recommended the Township move to an

impervious area based billing system for all parcels in the

future following the initial implementation of the

stormwater fee. To provide this information the Township

will need to gather new updated data including aerial

photography that captures the areas of impervious surface

in the Township. With this approach, all property owners

would be billed based upon the impervious surface on

their specific property. The data and effort required for

this approach are included in the recommended programplan, and could be completed in the next 1 to 2 years.

Based on one model of the program of services and level of

funding currently under consideration, ratepayers could

expect to pay approximately $56 per billing unit annually,

based upon their assigned tier. However, the final rate has

not yet been determined.

What Activities Would be Funded by aDedicated Stormwater Fee? Capital Improvements projects focused on system

upgrades in support of flood mitigation and water quality

protection.

Increased inspections of new and existing stormwater

management features to ensure proper operation.

Proactive infrastructure maintenance, including

inspection, cleaning, and rehabilitation of pipes, inlets,

ditches, and culverts.

Watershed planning to help identify which projects are

most effective meeting Township infrastructure

management, water quality, and flood mitigation goals.
