• Update in order to implement the plan accordingly

Campus Branding• Multiple opportunities to enhance TAMU branding

• Arrival points, institutional identity and campus traditions

need to be leveraged.

Off-Campus Development• Will lead to new access points and the need for improved

systems to support TAMU users of these developments

What We Heard: Collectivelisten:

What We Heard: Infrastructure Focus Grouplisten:

Area around Emerging Technology, Polo Field and parking lots – if developed – requires infrastructure and maintaining storm water capacity.


New utility loop being completed behind Duncan Hall and may allow for modifications to visually and functionally improve the area.


The core of campus is congested with services and may impact planning.


White Creek issues extend beyond the campus boundaries.


Limited services in the Hensel Park area, but some are being provided to the Century Square development.

Water Courses and Storm Sewersstormwater:

Detention (Proposed)stormwater:

Vegetation, Water Courses and Detentionstormwater:

Impervious Surfacesstormwater:

Pavement Solutions stormwater:

Porous pavement is simply a type of asphalt or concrete pavement that allows water to drain through due to its coarse structure.

Allowing water to permeate through is important for recharging the water table and preventing pollutants from being washed into waterways.

Non-porous pavement does not allow water to go through, causing stormwater runoff.

Pavement Solutions stormwater:

Vegetated Swales and Rain Gardensstormwater:

Vegetated swales are sloped, shallow ditch-like features that contain vegetative plantings.

As water flows through the swales, stormwaterpollutants are removed from the water.

A rain garden captures and temporarily holds rainwater until the ground can absorb the water.

They can also be established in poorly drained areas, which are difficult to maintain as good lawn, as well as in open swales in parking islands.

Infiltration Bedsstormwater:

Subsurface Infiltration Beds provide temporary storage and infiltration of stormwater runoff by placing storage media of varying types beneath the proposed surfacegrade.

These storage/infiltration beds are important to replenishing the groundwater supply and to retaining stream base flow during dry weather.

Athletic and Intramural fields can be used as storage/infiltration beds.

Tree Trenchesstormwater:

Tree Trenches are continuous planting strips, typically 2.5-3.5 feet deep, filled with a new soil mix.

They provide adequate growing space for tree roots and also create opportunities to capture and even infiltrate stormwater.

Tree Trenches can be continuous excavated areas that are open at the surface where existing soils are amended or covered with modular paving at the surface for light traffiic.

Underground Systems stormwater:

Swenson Civil EngineeringUniversity of Minnesota Duluth

Through integrated use of permeable paving, rain gardens, and an underground storm water retention system, 90% of the average precipitation is captured and treated on-site.

The underground system allows infiltration to reduce runoff volume.

Cisterns (Rainwater Harvesting)stormwater:

Rainwater harvesting, or the practice of capturing and collecting rainfall for reuse on-site instead of allowing it to runoff, is an effective strategy for reducing water use.

The water collected is used to irrigate nearby grass athletic fields, trees and lawns on the plaza area.

Vegetated Roof Systems and Roof Gardensstormwater:

Vegetated roofs systems help to hold precipitation and prevent runoff.

A series of thin layers supporting a top layer of low growing, drought tolerant vegetation.

The several layers are; a waterproofing layer, a root barrier, a drainage/storage layer, growth media, and the actual vegetation.

Education and Outreachstormwater:

Public education and outreach programs to further stormwater education and provides educational materials to students, faculty, and staff.

Some of these programs include drain marking sessions with students, volunteer stream clean up days, and educational seminars open to the entire campus community.

Stormwater Solutionsstormwater:

REGIONAL SOLUTIONS• Restoration of the “natural

drainage system” of streams and

swales,

• Re-vegetation of specific areas of the campus

• Detention Basins/Retention Basins

• Increased Permeable Surfaces on Campus

CAMPUS SOLUTIONS• Bioswales (Pedestrian Routes,

Parking Lots)

• Rain Gardens (Drainage Challenged Areas)

• Infiltration Beds

• Tree Trenches

• Permeable Pavement (Pedestrian Routes, Parking Lots)

PROJECT BUILDING SOLUTIONS• Vegetated, Green Roof

• Underground Systems

• Cisterns

• Bioswales

• Permeable Pavement

UNC Chapel Hill Stormwater Planstormwater:

DRIVERS OF THE STORMWATER MASTERPLAN

• NPDES Permit• National Pollutant Discharge Elimination

System Phase II Stormwater permit requirements

• Infrastructure Management

• Sustainability

ENVIRONMENTAL OBJECTIVES

• Balance growth with preservation of the natural drainage system

• Manage storm water as an opportunity not a problem

• Recognize that UNC-Chapel Hill is part of the Cape Fear Watershed

• Reinforce the University’s position as a

Role Model


The recommendations were divided into four generic categories:

• Best Management Practices (BMPs) both structural and non-structural

• New Policies, Practices and Procedures

• Recommendations for Flooding

• Recommendations for Illicit Discharges


Energy Services Department Responsible for oversight and management of UNC’s stormwater system infrastructure and master planning.

EHS Department Responsible for ensuring that the University meets local, state and federal requirements with regard to stormwater permitting, stream buffer protection, and water quality protection.

Grounds Department Responsible for cleaning and maintenance of stormwater inlets, catch basins, pipes and structural BMPs.

Facilities Planning and Construction Responsible for ensuring that buildings and other campus amenities are designed and constructed in ways that minimize their impacts on campus water quality.

UNC’s Stormwater Management program responsibilities are divided among several departments:


KEY RECOMMENDATIONS

1. It is best to manage stormwater where the problem is generated. This approach prevents exacerbation of downstream problems.

2. A number of Stormwater management options–

large and small–distributed throughout a drainage area are inherently better than a single large solution, which if it fails, will have far larger consequences.

The UNC stormwater system is comprised of thousands of catch basins and inlets, miles of piping, dozens of structural best management practices (BMPs) and outfalls that discharge stormwater

TAMU Stormwater Master Plan (2016)stormwater:

Conclusions:

• Improve management models by incorporating better, recently gain information.

• Use the improved models to evaluate the changes on East Campus with respect 1987 baseline conditions.

• Establish a more reliable 2016 baseline condition for White Creek and Turkey Creek.

• Model the current 5-year plan to compare the 1987 and 2016 baselines and address the places where an increase discharge is calculated.

Recommendations:

1. Collect and Organize storm sewer data

2. Utilize a different approach to modeling for regional detention vs. project-based detention

3. New regional detention under consideration:• Two detention basins on eastern branch of

White Creek• One detention basin on western branch• Further detention at junction east and off

campus branches• One detention basin downstream of 2818

• Proactive management of stormwater erosion
