Strategic and Integrated Stormwater Management Through Open Space Master Planning
Celso Guitian, UMBC Matt Thomasson, RK&K Engineering Amelle Schultz, Ayers Saint Gross Architects & Planners Moderated by: Ted Brown, Biohabitats
2
Learning Objectives Understand the importance of an integrated approach to campus planning of stormwater management elements, open spaces and natural areas. Understand the benefit of using thoughtful landscape elements to improve water quality, protect downstream areas, define the character of open spaces, and reduce maintenance. Learn how innovative modeling techniques provide dynamic updating of the campus hydraulic model and how this translates to better asset management and compliance with increasingly more stringent environmental regulations.

UMBC Campus an innovative case study
UMBC in Numbers Founded in 1966 520 acres 13,640 students 3.9 million SF of space 6,800 parking spaces $68 million in annual research

UMBC Campus Successful Outdoor Development
7
Environmental Challenges
Fairly rapid and consistent student growth of 1-2% per year Since our last masterplan in 2009, we had undertaken nine major building projects – each experienced a certain degree of frustration with the environmental (stormwater) regulatory process. While we supported the goals of the regulatory agencies, the specifics of the regulations discouraged the quality of outdoor spaces that make a university campus successful.

UMBC Campus Impact of Stormwater Management
9
Environmental Challenges
Inconsistency in project response to site challenges Historic roadways and parking areas with little or no treatment of stormwater runoff Four streams running through the campus carrying runoff from upland areas Poor historic documentation of stormwater improvements
10
Environmental Opportunities Project Goals
Develop a holistic, campus-wide approach to stormwater management Provide the university with an implementation plan that addresses our stormwater management responsibilities Partner with MDE to develop a management plan that will provide predictability when projects are reviewed for permitting Develop a tracking tool to coordinate management and maintenance programs
11
Environmental Opportunities Additional Project Goals
To provide for a more unified campus environment, highlighting the unique character and setting of the university Establish a set of guidelines that will serve as a policy and visioning tool during planning and design of future projects Develop an Open Space Framework
12
Open Space Planning What are the advantages of studying our open space networks?
13
Why should we improve open space and pedestrian networks?
Improves overall campus setting Enhance the University’s image as premier institution Contributes to improved wayfinding Humanizes the landscape for students, faculty, staff, and visitors Creates a sense of place with consistent materials and details Create meaningful gathering places throughout campus Integrates SWM into the campus landscape aesthetic

Does your campus value the aesthetics of a landscape integrated with stormwater management?
If not, do you have suggestions on how this might become more appreciated?
30
Open Space Planning & Stormwater Integration
Cohesion among: Buildings Open Space Stormwater Management Working Landscapes that incorporate SWM What do you mean by cohesion between buildings and Open Space?
31
This is NOT a cohesive campus facility
Perimeter fence Separates parking from buildings No passive/active use Not attractive Does not create much habitat Valuable campus footprint near buildings
32
Bio-Retention Facility & Courtyard in Traffic Circle
SWM incorporated into landscape Valuable open space created Active use Attractive Utilized area within a traffic circle
33
Regulatory Agency Buy In Stormwater Intuitional Management Plan (IMP)
Tracking of stormwater management credits Documented outflows at points of analysis from Campus More streamlined permit process for projects in master plan Regional/Campus approach to stormwater treatment Basis for MS4 Compliance
34
Watershed Model GIS Entire campus landcover modeled Two major points of discharge from campus Hydraflow Hydrographs 70+ existing SWM facilities 13 sub drainage areas Allows us to analyze SWM impacts by sub drainage area instead of project limits
35
Future Building Development
Not limited to a hydrologic analysis of project area Impact to the overall campus drainage area SWM facilities outside of immediate project area Analyze the impact of standalone SWM projects Non-structural practices within a drainage area How do you keep the models up to date as the Master Plan is built out?
36
Stormwater Management Tracking Tool – Asset Management
Updated GIS feature classes Revised land cover SWM facility data Drainage areas Storm drain pipe and structure data Permitting documents
37
Asset Management Strategy
Design RFP A/E Team GIS Protocol Tool Requirements Design Construction RFP Detailed As-Built Survey Requirements Construction Detailed As-Built Survey (Construction) Construction Contractor Provides CADD As-Built A/E Team Completes GIS Protocol Tool Template UMBC Merges Changes Into GIS Model
38
So, we have a plan – what are the next steps?
Regulatory buy-in (Approved MDE Institutional Management Plan) Use the open space design guidelines during project development to create consistency Require all A/E Teams to provide consistent reporting of calculations to insert into the GIS asset management tool
39
So, we have a plan – what are the next steps?
Funding the improvements Ensure that each capital project contributes to our campus-wide goals and requirements Submitting a site improvement capital project to address both infrastructure upgrades and stormwater improvements Engage students through cleanups, education and class projects Conduct research to measure and track success
