1.0 Wetland Water Budget

This report summarizes the wetland water budget prepared for the Belle Mead wetland restoration.

The methodology presented is based on the Regionalized Water Budget Manual for Compensatory Wetland Mitigation Sites in New Jersey (Water Budget Manual) 1.

2.0 Wetland Definition

The proposed wetland will restore existing wetlands to be displaced by construction activities at the Belle Mead site. Freshwater wetlands within the project area were delineated by Bohler Engineering of Warren, NJ in 2009. A NJDEP Letter of Interpretation (LOI) Line Verification was issued October 20, 2010. The LOI was renewed on October 5, 2015. Field visits were conducted on January 12 and March 9, 2016 to gather information on dominant vegetation and hydrology in the wetlands.

1 New Jersey Department of Environmental Protection. Regionalized Water Budget Manual for Compensatory

Wetland Mitigation Sites in New Jersey.

Figure 1 - Looking west from approximately the center of Wetland C

Belle Mead Wetland Restoration Water Budget

The proposed wetland, measuring a total 158,800 square feet in size, will restore 47,200 square feet of Freshwater Emergent Wetland (PEM), 51,600 square feet of Freshwater Shrub Wetland (PSS), and 60,000 square feet of Freshwater Forested Wetland (PFO).

The Hydrogeomorphic Approach for Assessing Wetland Functions classification of the proposed wetland is as follows:

Geomorphic Setting – Depressional Wetland Water Source and Transport – Precipitation Hydrodynamics – Vertical Fluctuations

The proposed wetland will replicated the hydrologic conditions of the existing wetlands in the area, which do not exhibit standing water during the majority of the year.

The site lies within the Piedmont physiographic New Jersey province2. According to the Water Budget Manual, “the Piedmont is characterized by interbedded sandstone, shale, conglomerate, basalt, and diabase. Shale and sandstone underlie the valleys and lowlands; basalt and diabase, which are more resistant to erosion, form the ridges and uplands. Water is found in the joints and fractures of the shales and sandstones such that they are, in places, capable of yielding large quantities of water. The basalt and diabase generally have low permeability and are poor aquifers.”

3.0 Mitigation Site Selection

The selected location for wetland mitigation is adjacent to an existing wetland at the low point of the site, just upstream of the Royce Brook tributary. The footprint of the proposed wetland will overlap a portion of the existing wetland, as shown on the design drawing. The location of the wetland mitigation has been chosen in support of the mitigation goals, which are to restore the function of the displaced wetland, including water-quality protection, nutrient cycling, and plant diversity. The location will have similar hydrogeomorphology to the existing wetlands.

As discussed in the Water Budget Manual, AECOM reviewed available GIS layers from the New Jersey Department of Environmental Protection’s (NJDEP) Bureau of Geographic Information Systems. The following GIS coverages are not located in the vicinity of the site:

Hydrography (state 3rd order or higher);

Natural Heritage Priority Sites;

Ambient Stream Quality Monitoring Sites;

Chromate waste sites; and, State Open Space.

The GIS coverages observed in the vicinity of the site are shown on Figure 2 - New Jersey Department of Environmental Protection. GIS Coverages. The surveyed topography of the existing site and the proposed site topography are shown the design drawings.

4.0 Water Budget

The Water Budget Manual defines the hydrologic cycle of a wetland as follows:

S = [P + Si + Gi] – [ET + So + Go]

Where:

S = change in volume of water storage in a defined area over time;

P = precipitation;

Si = surface-water inflow;

Gi = ground-water inflow;

ET = evapotranspiration;

So = surface-water outflow; and, Go = ground-water outflow.

The process of defining each of these terms is described in more detail below:

4.1 Precipitation

AECOM located weather stations in the vicinity of the site with at least 30 years of rainfall data through the National Oceanic and Atmospheric Administration’s National Centers for Environmental Information3. The site is located between two rainfall gages with long data records, Wertsville 4 NE, NJ US (GHCND:USC00289363) at latitude/longitude coordinates of 40.4528, -74.808 and Blackwells Mills, NJ US (GHCND:USC00280847) at latitude/longitude coordinates of 40.4593, -74.5836.

Both of these stations have rainfall records available from 1956 to the present, though they are not continuous. Due to significant gaps in the data record at the Blackwells Mills station, AECOM has used the Wertsville 4 NE weather station, which is the station closest to the site, as the representative station for this water budget. This information has been used to develop the representative wet, dry, and average year data.

Belle Mead Wetland Restoration Water Budget

AECOM selected the representative years after examining daily precipitation data and annual climate summaries for the Wertsville 4 NE weather station. The selection was based on precipitation received between January and June, as discussed in the Water Budget Manual. The annual precipitation at the station is summarized in Table 1 - Total Annual Rainfall at Wertsville Station.

AECOM selected 2014 as the representative average year, 2011 as the representative wet year, and 1986 as the representative dry year. Although 2011 included a large storm in August, it also received higher levels of precipitation from January through June. Snow has been included in the calculation, assuming that 10-inches of snow equals 1-inch of precipitation4.

Graphs of precipitation for representative years by both day and month and original NOAA weather station precipitation reports are included in Appendix 1 – Precipitation Information.

4.2 Surface Water

The proposed wetland will receive surface flows from site runoff but will not receive channelized flow.

The proposed wetland will discharge to the Royce Brook tributary, through the existing on-site channel which flows to the north to its confluence with Royce Brook. The proposed drainage area and Royce Brook Tributary are shown on Figure 3 – Proposed Wetland Drainage Area.

Belle Mead Wetland Restoration Water Budget

AECOM calculated the contribution from non-channelized flow using the Soil Conservation Service (SCS) curve number method presented in the Water Budget Manual. In this method, each day’s precipitation beyond the initial abstraction contributes to the daily wetland water budget.

AECOM calculated SCS curve number from proposed land use and National Resources Conservation Services’ Hydrologic Soil Group, according the methodology presented in TR-555. The area of the site discharging to the property is 145 acres. The entire area will be loamed and seeded, or otherwise vegetated. The calculation for the site CN value is included in Table 2.

Table 2 - Site CN Value Calculation

Hydrologic Soil Group Area (ac) Land Use CN

Group D 62.8 Grass 89 Group A/D 82.0 Grass 68

Total 144.8 Grass 77.1

According to the water budget manual, runoff for each day can be calculated as follows

Q = (P-0.2S)2 /(P+0.8S)

S = (1000/CN) – 10

Q = runoff (inches) P = rainfall (inches) S = potential maximum retention after runoff begins (inches)

Potential maximum retention after runoff begins is equal to 2.97 inches and the initial abstraction is

0.59 inches. The NRCS Hydrologic Soil Group Report is included in Appendix 2.

5 Cronshey, R. (1986). Urban hydrology for small watersheds. US Dept. of Agriculture, Soil Conservation Service, Engineering Division. Technical Release 55.

Belle Mead Wetland Restoration Water Budget

During large storm events, the proposed wetland will discharge over a broad-crested weir to the Royce Brook tributary. AECOM calculated discharge over the weir using the broad-crested weir equation6.

Q = C L H3/2

C = 2/3 * Cd * (2g)

C = weir coefficient L = Crest length g = Graviational constant Cd = Discharge Coefficient

The daily flow capacity of the weir exceeds the storage volume of the wetland above the weir. Thus, for each daily time step, any water stored above the weir was assumed to discharge over the weir during that time step. This method is based on the water budget example presented in the Water Budget Manual.

The Royce Brook Tributary is expected to receive inflow from water discharging over this weir during large storm events. At other times, the Royce Brook Tributary will receive inflow from the proposed wetland through exfiltration from the wetland.

The results are graphed in Figure 4 and Figure 5 – Water Budget Graphs by Month and by Day.

4.3 Groundwater

In 2007, AECOM collected a boring log7 at the location of the existing wetland. This boring log, which did not encounter groundwater, extended to a total depth of 9.5-feet below ground surface. Based on this observation, the topography of the site, and field observations that the wetland dries out between storm events, groundwater is not expected to significantly contribute inflow to the proposed wetland.

Water will discharge out of the wetland through exfiltration. The exfiltration rate has been calculated using Darcy’s law as described in the Water Budget Manual. Soil data from the NRCS Soil Survey indicated that the top soil in the vicinity of the proposed wetland is silt loam (Raritan silt loam). The boring log indicates that the subsurface is composed of a one foot layer of sand, underlain by clay.

Bedrock was encountered at a depth of 8.5-feet below ground surface.

Hydraulic conductivity values for the site have been taken from the NRCS Soil Survey, which reported a saturated hydraulic conductivity value for the soil unit of 9.17 micrometers per second (1.3 in/hr).

Vertical conductivity was assumed to be 1/10 horizontal hydraulic conductivity.

Because the entire proposed wetland has the same hydraulic conductivity, AECOM defined a single section of flow for exfiltration. AECOM applied exfiltration to the wetted pool, assuming saturated conditions. The NRCS Saturated Hydraulic Conductivity Report is included in Appendix 3.

4.4 Evapotranspiration

A monthly evapotranspiration rate has been calculated for the water budget using the Thornthwaite equation, as described in the Water Budget Manual:

ETi = 1.6 (10 Ti / I)a

ETi = potential evapotranspiration for month i (cm/month) Ti = mean monthly temperature (°C) I = annual heat index = (Ti / 5)1.5 a = 0.49 + 0.0179 I - 0.0000771 I2 + 0.000000675 I3

The calculation was based on monthly temperature normals recorded at the Wertsville 4 NE weather station. The Thornthwaite calculation is summarized in Table 3 - Thornthwaite Evapotranspiration Rates.

Table 3 - Thornthwaite Evapotranspiration Rates

Month T (°F) T (°C) ET (cm/month)

January 29.1 1.61 0.00 February 31.6 0.22 0.00 March 39.0 3.89 1.21 April 50.0 10.00 3.96 May 59.8 15.44 6.83 June 68.3 20.17 9.55 July 74.2 23.44 11.53

August 72.1 22.28 10.82 September 64.4 18.00 8.28 October 52.8 11.56 4.75 November 44.1 6.72 2.40 December 33.9 1.06 0.24

I = 48.60 a = 1.26

In the water balance, ET has only been applied to the wetted pool. The original NOAA weather station normals reports are included in Appendix 4 – Monthly Normals.

The results are graphed in Figure 4 and Figure 5 – Water Budget Graphs by Month and by Day.

4.5 Change in Storage Volume

For each day of the representative wet, dry, and average year data, AECOM solved the wetland change in storage equation:

S = [P + Si + Gi] – [ET + So + Go]

AECOM calculated the wetland stage-storage relationship from the wetland contours, as shown on the design drawings. The stage-storage relationship is shown in Table 4.

Table 4 - Wetland Stage-Storage Relationship

Stage (ft) Area (ac) Storage (ft3) 97 1.13 0 98 2.34 75,737 99 3.72 207,871

The water budget indicated that the wetland will lack standing water for a majority of the year. This is consistent with field observations of existing wetlands on-site. The wetland storage was assumed to be zero on January 1st for each of the modeled years. The monthly water budget for each modeled year is included in Table 5 – Monthly Water Budgets. The daily water budgets are included in Appendix 5 – Daily Water Budgets.

The results are graphed in Figure 4 and 5 – Water Budget Graphs by Month and by Day.
