The "Storm Water Facility Guidebook" provides guidance on who should be the applicant for storm water installation as part of Highway Occupancy Permit work, alternatives to including the local government as an applicant, and how to prepare an agreement between developer and local government should the local government be an applicant.

This guidebook has been prepared to assist designers, local governments, and landowners with projects that require installation of storm water facilities and/or modifications to existing storm water facilities during the Highway Occupancy Permit (HOP) process. A policy addressing such facilities was issued on June 24, 2010, by Strike-Off-Letter (SOL) 470-10-03 (HOP policy). The HOP policy discusses modifications to Chapter 5.1 (Storm Water Facility Maintenance – Responsibility) of PennDOT Publication 282 (HOP Manual) as further revised and updated in December 2011 as set forth herein. In some instances, the law requires that the local government in which an HOP project is located must be the permittee or co-permittee with the landowner for enclosed surface storm water facilities. The HOP policy provides an avenue to local governments for landowners to fund future maintenance. This guidebook explains the five categories of HOP-installed or modified facilities and which categories require the local government to be a co-permittee.

This guidebook also provides possible alternative storm water designs for landowners and local governments to consider when designing an HOP project to create situations where the local government will not need to be a copermittee. For those local governments that agree to take on maintenance responsibilities, the HOP policy provides that the landowner is responsible for providing funding to the local government to offset future maintenance costs. In the alternative, a local government may consider requesting security for future costs as part of land development review. Why is Storm Water Maintenance important? In previous presentations and policy on the subject matter, “open surface storm water facilities” were referred to as “surface storm water facilities”, and “enclosed surface storm water facilities” was referred to as “subsurface storm water facilities.” Moving forward, to be consistent with the Department’s Maintenance Manual, Publication 23, the Department will use the terms “open surface storm water facilities” and “enclosed surface storm water facilities.” Identifying storm water maintenance responsibilities is of high importance for every HOP project. The maintenance of storm water facilities is required to achieve the full expected life from facilities and to protect the travelling public from hazards related to ill-performing storm water systems. A functioning storm water infrastructure is critical to support the movement of goods, people, and services on State highways. The HOP policy is beneficial to all parties, including the state tax payer. It provides an opportunity to have landowners, who are altering land for their purposes, fund maintenance of enclosed surface storm water facilities (as opposed to PennDOT or local governments). Additionally, the policy allows all involved parties an opportunity to provide input towards the ultimate design solution.
