Collaborative Water Quality Improvements
We recognize that achieving our community’s water quality goals is much more efficient and effective when working together. A great example is the Conewago Creek cooperative effort with Londonderry Township in Dauphin County. Read more about this public-private approach made possible by local leaders in our area. Mount Joy Township is also proud of our collaborative Streambank Stabilization Project with the Green Meadows Mobile Home Park on Radio Road. We hope to break ground to directly improve the Conoy Creek in late 2020/early 2021!
Stormwater Management Permits
A permit is typically required for all regulated activities, including:
- Land development
- Removal of ground cover, grading, filling, or excavation
- Construction of new or additional impervious surfaces
- Construction of structures
- Installation or modification of stormwater management facilities and conveyances
- Diversion or piping of any watercourse
Permit applications and instructions can be found on our Forms & Applications page. Mount Joy Township uses a three-tiered permit system for stormwater management:
Stormwater Exemption – The cumulative installation of 1,000 sf. of impervious coverage on a lot may be exempt from the requirement to submit a Stormwater Management Site Plan.
Small Project – The cumulative installation of 5,000 sf. of impervious coverage and/or earth disturbance may be eligible for approval as a Small Project, which requires volume control for at least the first inch of rainfall from impervious surfaces.
Site Plan – All regulated activities that do not qualify for an Exemption or Small Project must submit an engineered site plan to show stormwater management.
