UNC Stormwater Plan Review and Construction Tracking
Standard Operating Procedure
Plan Review
Stormwater reviews are conducted by Energy Services staff to ensure that construction, redevelopment,
and maintenance projects on campus meet requirements outlined in the UNC Stormwater Design
Guidelines. Stormwater review staff will find out about new projects manager in one of the Facilities
Planning and Design Groups.
Large project, including new buildings and athletic facilities and major renovations are managed by the
Planning and Project Management Group (currently headed by Nathan Harms). The project manager
from this group will organize planning meetings from project conception through the design process.
Stormwater and other utility staff may become involved during preliminary planning stages. In addition,
stormwater reviewers often meet with the civil designer early in the project to discuss stormwater
management on the site and head -off problems early in the process.
Smaller projects and renovations are managed by the Facilities Engineering Group. These project
generally do not hold planning meetings, but designers may contact stormwater staff with questions.
For any size project, plan review is managed through the Dr. Checks (aka Projnet.org) online software
tool. To get an account on Dr. Checks, contact the director of the Facilities Technology Group (currently
Abbas Piran). Generally, the project manager will upload plan sets, specifications, and reports to Dr.
Checks for a Schematic Design (SD) phase, Design Development (DD) phase, and Construction Document
(CD) phase, but some projects may have more or fewer review phases. Stormwater staff will review
each project at each phase, until all requirements have been met.
Interior Only Projects
• Organizer: UNC Planning and Design Project Manager
• Stormwater Staff Roll: Each UNC department is responsible for reviews in their own area of
expertise. For projects that affect interior spaces only (most UNC projects) the reviewer should
open the plans to make sure there is no impact stormwater infrastructure or increase
impervious area. In this case, enter the following comment:
This project does not appear to propose any exterior work that would increase the
impervious area on campus. However, if impervious areas are added later (i.e. sidewalks,
parking, roofs) please contact me or the UNCStormwater Utility Manager (919-923-8700) to
discuss Stormwater treatment requirements.
Projects with Exterior Work
• Organizer: UNC Planning and Design Project Manager
• Stormwater Staff Roll: Each UNC department is responsible for reviews in their own area of
expertise. Steps for all other review plans include:
1. Project manager uploads review documents to Dr. Checks. An automated email is sent out to
potential reviewers (including stormwater staff) with a due date for the review, usually 2
weeks from the upload.

2. Reviewer downloaded plans and saves them to the project folder in the
\\facdraw\eis\Stormwater\1- Proiects folder in a folder titled "designConst".
3. Reviewer checks the Stormwater report and plans to ensure that the project will meet
requirements outlined in the UNC Stormwater Design Guidelines. Complete the checklist
from Appendix A of the guidelines and save it in the folder with the downloaded plans. Enter
comments describing deficiencies in the plan and report into Dr. Checks. Download Dr.
Checks comments and save them to the project folder. If this is not the first phase of review,
start by back -checking comments from previous reviews.
4. After comments are addressed by the designer, they may be backchecked and closed in Dr.
Checks. Not all project managers require reviewers to close all comments.
5. After new review comments are submitted to the designer, the Stormwater Reviews
spreadsheet should be updated with a new review date here
\\facdraw\gis\Stormwater\Review\Stormwater Reviews Updated.xlsx.
6. In practice, there will often be intermediate reviews not entered in Dr. Checks where the civil
designer sends plans directly to the reviewer between Dr. Checks reviews. In this case,
complete the review as you would a Dr. Checks review, but write the comments in a word
document and save it as a PDF. Send the comments back to the reviewer in an email,
copying the UNC project manager and the outside design project manager (usually the
architect) if there is one.
7. When the project results in an increase in building square footage a town approval is
required. Permit applications are submitted by the Planning and Project Management group
(currently Nathan Harms). For most of campus, the project will complete an 01-4 Site
Development Permit Application (see 01-4 Stormwater Performance Standards).
a. Although all of the stormwater reviewers comments may not have been resolved prior to this
application submittal, the reviewer should make sure that the Stormwater Report shows that
the 01-4 standards have been met (Volume and Peak Discharge) prior to this submittal.
b. There are two sections in the application itself that the reviewer should check for
correctness. Section G should account for the planned increase in impervious area from the
project; Section H should account for the volume offset credit being purchased by the project
from an existing SCM.
8. When the reviewer receives CD documents that have addressed all of the comments and
meet all of the UNC design requirements, the reviewer completes an approval letter stating
that the project meets all design requirements and listing any buydown requirements that
must be completed prior to project completion. The form approval letter is available in the
Design Guidelines folder. Print the approval letter and the "Nutrient Offset" tab from the
SNAP tool (if needed) and bring them to the Stormwater Utility Manger (currently Sally Hoyt)
to sign. Scan the signed documents and email them to the civil designer copying the UNC
project manager, the design project manager, and the Stormwater Utility Manager. Create a
folder in the "DesignConst" folder called "OApprovedPlans". Save a copy of the signed
approval letters, the Stormwater Report, and the approved plans including Grading and
Drainage sheets, Stormwater Details, SCM plans and details. Update the Stormwater Review
Spreadsheet with the date of the approval and a hyperlink to the approved plan set and
Stormwater Report.

Construction Tracking
Kickoff meeting
• Organizer: UNC construction manager
• Stormwater Staff Roll:
o Provide contractor project manager and site superintendent with contact information
o Let contractor know that we should be contacted when unknown pipes are uncovered
during construction to help determine if the pipe active.
o Ask the contractor to contact us prior to SCM installation so that we may observed
critical stages of installation.
o Emphasize that we should also be involved when changes to the storm drainage design
are required. However, it is important to remember that direction to the contractor
should always come from the design team. Also make sure that the UNC construction
manager is aware of any issues onsite.
Weekly Meetings
• Organizer: Lead contractor
• Stormwater Staff Roll:
o Attend meetings to help facilitate construction activities and to make sure that
stormwater staff are involved in critical decisions.
o Stay informed about current activities and schedule site visits to observe installation of
storm drainage infrastructure and SCMs as needed.
Construction Observation
• Responsibility: Design Engineer
• Stormwater Staff Responsibility
o Check that the design engineer is doing regular site visits
o If staff time allows
■ Accompany design engineer on site visits
■ Take photos and file them
Project Closeout
• Responsibility: UNC Stormwater Staff
o As of January 1, 2021, certify that that the project meets standards using form letters in
\\facdraw\gis\Stormwater\Review\Approval Letters
o After as -built drawings have been received add the new project infrastructure and SCMs
to the GIs database.
o Create mapbook pdf document for new SCMs and link it in GIS.
