The Environmental Finance Center worked with several municipalities in Lancaster County, Pennsylvania, to recommend a sustainable financing approach to help meet their stormwater management goals. In one municipality, Warwick Township, it was found that the cost to replace their gray infrastructure storm sewer pipe system would be over $1.9 million in 30 years. However, the cost to maintain and renovate all municipally owned BMPs over 20 years through an established asset management program would be just over $260,000. That’s a savings of almost $1.6 million. This report details Warwick Township's financing approach.
