Appendix D FUTURE CONDITIONS : STORMWATER MODELING

The objective of an analysis of future proposed conditions is to understand the hydrologic response due to changes in the land cover, typically associ-ated with an increase in impervious cover. The shift in hydrology then needs to be balanced with appropriate strategies that can meet stormwater management regulatory requirements (noted in Appendix C) while pro-viding functional and integrated landscapes on campus. Modeling Potential Benefit of Green Infrastructure RetrofitsTo illustrate the effectiveness and benefits of applying green infrastructure strategies, the integrated InfoWorks 1-D and 2-D models were reconfig-ured to characterize two potential retrofitting scenarios on campus. In the two examples below, the first example shows the volume reduction and associated water quality benefit of porous pavement, while the second example shows the benefit of providing underground detention in a high density area of campus.

Example 1– Permeable Paving Parking Facility– Yellow Lot Livingston CampusIn order to demonstrate the applicability and effectiveness of stormwater BMPs or low impact development (LID) practices, a conceptual design of a permeable paving parking facility is considered for the Yellow Lot of the Livingston campus. A schematic representation of this BMP and its concep-tualization for the Yellow Parking Lot is shown in Figures D-1 and D-2.

The Yellow lot is currently a conventional asphalt parking facility with a total area of approximately 18 acres. Surface characteristics of the parking lot were adjusted in the 2-D model to represent the characteristics of a per-meable paving surface as well as the underlying site soils. The limiting fac-tor to the efficacy of permeable pavement is the generally poor infiltration rates of the native soils on the Busch and Livingston campuses as opposed to the permeable paving itself. Nevertheless, the poor onsite soils still have an infiltration capability, especially when considered on large areas such as the Yellow Lot. Water stored in the pores can also dissipate through evaporation during non-winter months. In the model, the asphalt parking facility with close to 100% impervious cover is changed to a pervious cover with low infiltration rates.

The model response to the improved permeable surface is shown in Figure D-3. Peak runoff and total volume generated by the subcatchment are reduced to 64% and 81% of the pre-BMP (i.e., conventional asphalt) values, respectively, for an SCS Type III 10-year design storm event. As evident from the system response, the implementation of permeable pavement provides meaningful volume reduction and water quality benefits which should also translate into lessened erosion potential from reduced peak flow rates.

Example 2 – Storage Facility– Dining Hall Parking Lot Busch CampusThe Dining Hall area is an area that is known to frequently flood on the Busch campus. Currently there is a stormwater facility along the edge of the Dining Hall parking lot, along Bartholomew Road. (Figure D-4) Installation of underground storage facilities is one of the ways to mitigate nuisance flooding problems in high density areas that lack space for green infrastructure implementation. Underground storage facilities typically consist of large diameter pipes placed closely and parallel to each other, with the area above the pipes providing functions such as parking or play areas. During rainy periods, the flow is diverted to the storage facility and subsequently released slowly by providing a smaller diameter outlet pipe that limits the volume and rate of water exiting the storage area, effectively reducing peak flow from the contributing drainage area. The effective-ness of these detention facilities can be enhanced by using perforated pipe to promote exfiltration to the shallow groundwater thereby reducing the runoff volume. During large rain events, the flow in excess of the storage volume will be released through overflow pipes into the receiving waters.

For this example, the 2-D model was used to assess the benefits of a storage facility under the Dining Hall parking lot. A storage node with a capacity of two acre-feet was placed under the parking lot and the flows generated from the adjacent subcatchments were diverted into this facility. The outlet pipe diameter of this facility was set to 12 inches. The model with existing conditions and the model response resulting from implementation of this facility are shown in Figure D-5 and D-6 respectively. As evident in the figures, the area affected due to flooding is reduced significantly after this storage facility is incorporated.

Modeling of Future Conditions On CampusThe analytical process for modeling future hydrologic and hydraulic condi-tions can be challenging in that it requires establishing a future condition scenario based on the best available information. For this planning effort, this information was primarily derived from the 2003 Rutgers Campus Master Plan prepared by Ayers/Saint/Gross Architects and Planners (ASG). In addition to the 2003 Master Plan, more recent planning efforts have been underway at Rutgers, especially with respect to the Livingston Campus and the new proposed business school. Additional planning in-volving housing on the east side of the Busch campus has also been under-way. A 2008 update to the Livingston Campus Master Plan was developed by Ayers/Saint/Gross that was largely conceptual and focused mostly on massing potential and preliminary programming ideas.

A combination of these data sources was used to create a future conditions impervious cover layer in GIS that was then used in the InfoWorks 1-D and 2-D models. For the Busch campus, direct measurement of impervi-ous cover from the Ayers/Saint/Gross master planning effort was adopted as the approach to developing future imperviousness values. For Livingston campus, impervious cover factors were assumed and associated with the predominant proposed land use (e.g., commercial, mixed used, residential, etc.). Tables D-1 and D-2 on the following two pages provides a summary of the model subcatchments with the existing impervious cover and future impervious cover percentages. (Subcatchments are shown in Figure D-7) In some cases, subcatchment impervious cover stays the same or decreases which means that either no land cover change is planned in the future or perhaps impervious cover is reduced in the future (e.g., a parking lot is converted to a building with landscaped areas).

Figure D-7 As shown in Appendix C this map shows the subcatchments and associated drainage points referred to in the tables on the following pages. The colors are used to help visually delineate the different subcatchments.

Table D-2 Livingston Campus existing impervious and future impervious cover percentages by subcatchment.


Storm sewer lines, conduits, and swales network were unaltered in the modeling of future conditions, as it was assumed that the stormwater from future development would be discharged to the same drainage network. Similar to existing conditions, model runs were performed for the 24-hour duration 100-, 10-, and 2-year design storms, as well as shorter intervals such as 1-year, 6-months and 3-months return frequency rainfall events. (The complete model results are included at the end of this Appendix in Tables D-10 through D-24.) Total rainfall volumes for design storm events were obtained from the Middlesex County and Somerset County data for New Jersey’s 24-hour rainfall frequency data of USDA Natural Resource Conservation Service. (http://www.nj.nrcs.usda.gov/technical/engineering/rainfall.html) The NRCS Type III distribution, appropriate for the coastal U.S. regions, was then used to develop the hyetograph patterns for indi-vidual design storms.

Tables D-3a and D-3b provide a summary of flow and volume output for existing and proposed conditions for the 10-year return frequency storm by subcatchment. The net changes in peak discharge and runoff volume are also presented by subcatchment. Appendix C contains similar model output for other return frequency storms that were analyzed. Table D-4 provides the summary of peak flow and total runoff values at various design points shown in Figure D-8. These design points are of interest as they are the points where flow leaves the Busch and Livingston Campuses. The net changes in peak discharge and runoff volume are also presented by subcatchment.

Table D-3b Flow and volume output for existing and proposed conditions for the 10-year return frequency storm for the Livingston Campus.


The following observations are made based on the values seen for the 10-year 24-hour design storm. As expected, the peak discharge and overall stormwater runoff volume generated increased in subcatchments where there is a projected increase in impervious cover. In general, increases are more significant in the subcatchments of the Livingston campus where the growth rate will be significant (e.g., associated with the residential housing and business school development).

It is interesting to note that flow and volume increases are not as pro-nounced as one might expect due to the NRCS soil types found on the Rutgers campuses and surrounding areas. Specifically, the majority of the soils on the Busch and Livingston campuses are categorized as hydrologi-cally poor soils, or hydrologic soil groups (HSG) C and D. The infiltration capacities of these soils are limited; therefore, these areas can generate sig-nificant amounts of runoff after the initial hydrologic losses are met, even in the absence of development. New development (buildings) occurring on such soils results in smaller variation in the peak flow and volume when comparing existing conditions to the future conditions. This is particu-larly evident for larger storms, such as the 10-year and 100-year events.

It is also important to evaluate the modeling output for existing and future conditions at both subcatchment and catchment scales. While the future conditions runoff peak rates and volume can increase from the existing conditions at some subcatchments, the reductions in impervious cover in other tributary subcatchments can lead to similar or even lower overall ac-cumulated flooding conditions at the downstream creeks and swale sections under future conditions. This system response can be seen in both Busch and Livingston campuses’ catchments, since the 2003 Master Plan proposes replacing surface parking lots with parking structures so that there is a net increase in open space in some subcatchments. For example, the increased peak flow due to higher imperviousness in subcatchments L102 and L105 in future condition is balanced by the imperviousness reductions in subcatch-ments L103 within catchment L1. As reported in Table D-3 (previous pages), the peak flow increases for subcatchments L102 and L105 (3.57 cfs and 5.12 cfs, respectively) are balanced by a decrease of 12.57 cfs in peak flow value in subcatchment L103. Overall, there is a reduction of 7 cfs in peak flow at the design point L1, as stated in Table D-4 (in red, bold type). Catchments and design points are shown in Figure D-8.

Figures D-9 through D-12 present the 2-D output of the existing and future conditions under a 10-year return frequency scenario. Model output does not show significant changes when comparing existing to future conditions in the areal extent of flooding across campus. This is due to two primary reasons. First, the 1D model set up is such that little upland flooding will occur unless there is a backwater effect caused by infrastructure capacity limitations or high flows further downstream blocking flows from the stormwater outfalls. For Livingston and Busch campuses, this phenomenon is mostly absent. This is also the result of having limited and incomplete information related to the stormwater collection and conveyance systems on campus.

The second reason is that, where flows and volumes do increase, the increases are mostly confined to the channels and streams that are well defined and have sufficient capacity such that they can accommodate increases in flow and vol-ume without substantially overflowing and causing a wider flood extent.

To illustrate this behavior, Figure D-14 shows a downstream cross-section of Buell Brook, where the existing conditions flooding extent does not change substantially for a range of storm events, even though there is sig-nificant difference in the depth of water. This is due to the capacity avail-able in the well-defined Buell Brook cross-section. Similarly, Figure D-15 compares the flooding depths for existing and future conditions for the 10-year design storm, where the differences can be seen as minimal. Figure D-13 shows the location of the Buell Brook cross-section.

Storage Implications and Watershed-Based Approach to Campus Stormwater ManagementNew development and redevelopment is subject to stormwater manage-ment criteria that typically require storm flow attenuation or detention at most sites. As part of the future conditions analysis, a preliminary estimate of required storage volume was developed based on a subcatchment and catchment basis. Initial volumes were determined outside of the integrated 1D-2D model using simplified NRCS methods that can be used to deter-mine storage volumes required to mitigate peak flow increases.

The estimated volumes were then translated into representative areas based on geometry assumptions (e.g., average depths) associated with common detention strategies such as wet ponds and constructed wetlands. The planning level area estimate provides useful context to understanding the amount of land area that may be necessary to set aside to meet the storm-water management requirements on campus. With strategic planning, these sites can be located and sized in a manner in which they can become assets (ecologically, aesthetically, educationally, etc.) to the University com-munity. Opportunities to combine storage requirements of multiple sub-catchments can also be explored using this analysis and planning approach.

Table D-5 and D-6 provides a summary of storage requirement estimates on the Busch and Livingston campuses. These estimates are conservative in that they reflect the over-control requirements associated with the 100-year design storm and they are developed at the subcatchment scale. When assessed at the catchment scale, the peak flows will be moderated or attenu-ated even further as the flow moves towards downstream reaches. Tables D-7 and D-8 include further data from the model including percentages of area required for a 3-ft storage facility.

In addition to the conventional regulation that addresses the pre vs. post-development peak and volumetric flows, other applicable regulations provide for alternative approaches to meeting storage requirements such as conducting hydrologic and hydraulic analyses that evaluate site runoff from a watershed and receiving water context where channel stability and downstream impacts are the primary focus. The New Jersey Soil Conser-vation District, for example, is concerned about the erosion potential in upland areas and eventual transport of sediments into water courses and finally into the Raritan River. Velocity can be used as a surrogate parame-ter for determination of the erosion potential in open channels and upland areas. Under this approach, it may be acceptable to provide alternative storage volumes, so long as channel stability and avoidance of downstream impacts can be demonstrated.

In order to illustrate this alternative approach, the InfoWorks 2-D output was evaluated by looking at the velocity vectors (values) for a design storm event (e.g., 2-year, 10-year return frequency) along the swales and water courses, and determining the stability condition in downstream channels under different upstream storage configurations. The goal was to reduce the future velocities to the corresponding values for pre-development or existing conditions at individual channel sections. Where velocities are greater than existing conditions, it suggests there is increased potential for channel scour-ing and therefore upstream storage will be required to reduce peak flows so that future velocity conditions are at the same level as or less than the exist-ing conditions scenario. If the existing condition channel morphology can be documented to be stable, a case could be made that controlling velocities under proposed conditions to the same level or less than existing conditions velocities would continue to yield a stable channel regime. This analysis would be necessary for a range of potential channel forming storm events (usually considered to be between a 1-year and 2-year return frequency, and sometimes inclusive of the 10-year return frequency for regulatory purposes). Further, if it can be demonstrated that there is no downstream flooding threat for extreme events (e.g., greater than the 10-year return frequency), then a case could be made that additional detention is not needed beyond the channel stability (i.e., velocity control) detention requirement.

Table D-8 Livingston Campus storage area required for a 3 foot deep storage facility as percentage of total area.


It is important to realize that the above example is only conceptual at this point and not based on field-determined geomorphological conditions. In addition, taking on such an approach is both a site-specific and receiving stream-specific exercise, such that it can’t be assumed that because the ap-proach is valid at one stream location it is also valid at another. Individual stream channel and catchment assessments and analysis are required.

Finally, it should be noted that stream velocities can be higher than litera-ture-based or regulatory mandated permissible thresholds and still main-tain channel stability due to the underlying stream bank and bed materials. Field documentation of these stream geomorphological characteristics may be required to receive a variance in a regulatory threshold. Using the above example the necessary storage was determined based on the target to reduce the future scenario velocities to the existing levels. Based on the uncalibrated model output, these velocities are higher under both scenarios than typical stable velocities. If a lower regulatory threshold were required (e.g., 6 feet per second) a significantly larger upstream storage or additional channel stabilization measures (such as vegetation or bank protection) would be needed to meet the threshold. One of the beneficial outputs of this Master Plan is that the University now has a watershed based hydrologic model that also has hydraulic analysis ca-pabilities that can be used in pursuing alternative approaches to meeting the stormwater management requirements on a campus or watershed/catchment scale as opposed to an individual site scale. This provides a wider range of thoughtful and effective design options to meet the regulatory requirements and can potentially yield more desirable environmental outcomes from a flow reduction and water quality improvement standpoint.

An example for catchment L4 involving the assessment of storage volume to meet the existing velocity values is discussed here. Catchment L4 is comprised of the subcatchments L401 through L405 that are tributary to the upstream end of Buell Brook. Velocity values for existing and future conditions for a total reach of 1,000 feet downstream of where the L4 dis-charges into Buell Brook were evaluated and are summarized in Table D-9. As can be seen in this table, the velocities for future conditions exceed the existing scenario for full reach when no storage is provided. Figure D-16 shows a schematic of the maximum velocities modeled for the 2.75 ac ft storage facility.

The next step is to analyze the 1,000 foot reach downstream of L401 with the benefit of providing storage upstream. An iterative analysis was per-formed to determine the volume of storage required to reduce the flow ve-locities to their existing condition values or lower. The analysis determined that for this reach, an estimated 2.75 ac-ft of storage is needed to manage velocities for the 10-year return frequency event. By comparison, it is esti-mated that approximately 2.81 acre-feet of storage is required to meet the peak discharge over-control requirement for subcatchments L401 through L405 for a 10-year storm event. This suggests that the storage requirement estimated based on the velocity analysis (i.e., erosion –based criteria) and peak flow control (traditional) are approximately equal for this catchment for the 10-year event. Yet, if the discussion above is considered, and it is shown that there is no downstream threat of flooding as Buell Brook enters into the Preserve before flowing into the Raritan River, then a case can be made that additional storage beyond the 2.75 acre-feet is not needed. In comparison, to meet the full range of over-control criteria (up through the 100-year return frequency storm) would mean that a total of approximate-ly 4.9 acre-feet of storage is required, or more than 40% more storage than that required for meeting a channel stability criteria.
