Diffuse Flow Plan
February 24, 2020
The tree houses meet the definition for decks. However the bridges connecting them, while at least 8' above the ground,
are not wood. They are constructed of composite materials, netting, etc. The bridges will not be solid-, some are more open
than others. The cargo net crawl will be very open- the cable bridge planks will be less open, but still not solid. Although
the material creating the net structure is not considered pervious, the overall bridges function as pervious structures since
stormwater from these areas will not be concentrated. The open segments will allow rainwater to fall to the ground 8-feet
below and will remain sheet flow upon landing on the ground. The ground will not be graded, so stormwater will continue to
flow in its existing overland path.

3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of
this application:
The Greensboro Science Center (GSC) is located within a 350 acre tract that also includes Country Park,
Jaycee Park, a portion of Guilford Battleground Park, Lewis Recreation Center and Forest Lawn Cemetery.
The GSC is a developed site with a 65,000 sf building and associated parking and a zoo with pathways, animal
exhibits and an aerial adventure course, SkyWild. An expansion of the zoo Is currently under construction.
The project area is generally wooded with a mix of trees and leaf litter.
3b. Attach an 8 Y2 x 11 excerpt from the most recent version of the USGS topographic map indicating the location
of the site
3c. Attach an 8 Y x 11 excerpt from the most recent version of the published County NRCS Soil Survey Map
depicting the project site
3d. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
1.33 miles
3e. Explain the purpose of the proposed project:
The project is for the construction of a tree house playground (tree house structures and connecting bridges)
that will be open to GSC patrons. A portion of the overall treehouse playground will be ADA accessible.
3f. Describe the overall project in detail, including the type of equipment to be used:
The playground will consist of seven tree house platforms, elevated at least eight -feet above ground and
connected by bridges. The bridges include an ADA accessible bridge, net crawl, ring crawl, balance bridge,
cable plank and cargo net hammock. The trees in the area need to remain for the construction of this project.
The tree houses will be supported by posts or anchored directly to existing trees. The installation will be by a
small skid steer that will meander around existing trees. Leaf litter and ground vegetation will be temporarily
disturbed, but trees will not be removed.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The tree house playground was redesigned and raised to at least 8' above ground, so there will be minimal impact on
stormwater and vegetation growth. The placement of the platforms was field investigated to determine the trees that
were most able to support the platforms and bridges.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. A
small skid steer will be used to place the poles and bring equipment during construction. Since the trees are needed
to support the project any construction equipment will move around the existing trees.
2. Buffer Mitigation
2a. Will the project result in an impact within a protected riparian buffer that requires buffer
❑ Yes ® No
mitigation?
2b. If yes, then identify the square feet of impact to each zone of the riparian buffer that requires mitigation and calculate
the amount of mitigation required in the table below.

Jurisdictional Determination Request
F. JURISDICTIONAL DETERMINATION (JD) TYPE (Select One)
I am requesting that the Corps provide a preliminary JD for the property identified herein.
A Preliminary Jurisdictional Determination (PJD) provides an indication that there may
be "waters of the United States" or "navigable waters of the United States"on a property.
PJDs are sufficient as the basis for permit decisions. For the purposes of permitting, all
waters and wetlands on the property will be treated as if they are jurisdictional "waters of
the United States". PJDs cannot be appealed (33 C.F.R. 331.2); however, a PJD is
"preliminary" in the sense that an approved JD can be requested at any time. PJDs do
not expire.
I am requesting that the Corps provide an approved JD for the property identified herein.
An Approved Jurisdictional Determination (AJD) is a determination that
jurisdictional "waters of the United States" or "navigable waters of the United
States" are either present or absent on a site. An approved JD identifies the limits of
waters on a site determined to be jurisdictional under the Clean Water Act and/or
Rivers and Harbors Act. Approved JDs are sufficient as the basis for permit
decisions. AJDs are appealable (33 C.F.R. 331.2). The results of the AJD will be
posted on the Corps website. A landowner, permit applicant, or other "affected
party" (33 C.F.R. 331.2) who receives an AJD may rely upon the AJD for five years
(subject to certain limited exceptions explained in Regulatory Guidance Letter 05-
02).
I am unclear as to which JD I would like to request and require additional information
to inform my decision.
G. ALL REQUESTS
Map of Property or Project Area. This Map must clearly depict the boundaries of the
review area.
Size of Property or Review Area 7.3 acres.
VThe property boundary (or review area boundary) is clearly physically marked on the site.

"Isolated", "No Significant Nexus", or "Upland Feature"). Please include the acreage
or linear length of these features as appropriate.
For Preliminary Jurisdictional Determinations:
■ Wetland and non -wetland features should not be identified as Jurisdictional, 404,
Waters of the United States, or anything that implies jurisdiction. These features can be
identified as Potential Waters of the United States, Potential Non -wetland Waters of
the United States, wetland, stream, open water, etc. Please include the acreage and
linear length of these features as appropriate.

1) The Corps of Engineers believes that there may be jurisdictional aquatic resources
in the review area, and the requestor of this PJD is hereby advised of his or her
option to request and obtain an approved JD (AJD) for that review area based on an
informed decision after having discussed the various types of JDs and their
characteristics and circumstances when they may be appropriate.
2) In any circumstance where a permit applicant obtains an individual permit, or a
Nationwide General Permit (NWP) or other general permit verification requiring "pre -
construction notification" (PCN), or requests verification for a non -reporting NWP or
other general permit, and the permit applicant has not requested an AJD for the
activity, the permit applicant is hereby made aware that: (1) the permit applicant has
elected to seek a permit authorization based on a PJD, which does not make an
official determination of jurisdictional aquatic resources; (2) the applicant has the
option to request an AJD before accepting the terms and conditions of the permit
authorization, and that basing a permit authorization on an AJD could possibly result
in less compensatory mitigation being required or different special conditions; (3) the
applicant has the right to request an individual permit rather than accepting the terms
and conditions of the NWP or other general permit authorization; (4) the applicant
can accept a permit authorization and thereby agree to comply with all the terms and
conditions of that permit, including whatever mitigation requirements the Corps has
determined to be necessary; (5) undertaking any activity in reliance upon the subject
permit authorization without requesting an AJD constitutes the applicant's
acceptance of the use of the PJD; (6) accepting a permit authorization (e.g., signing
a proffered individual permit) or undertaking any activity in reliance on any form of
Corps permit authorization based on a PJD constitutes agreement that all aquatic
resources in the review area affected in any way by that activity will be treated as
jurisdictional, and waives any challenge to such jurisdiction in any administrative or
judicial compliance or enforcement action, or in any administrative appeal or in any
Federal court; and (7) whether the applicant elects to use either an AJD or a PJD,
the JD will be processed as soon as practicable. Further, an AJD, a proffered
individual permit (and all terms and conditions contained therein), or individual permit
denial can be administratively appealed pursuant to 33 C.F.R. Part 331. If, during an
administrative appeal, it becomes appropriate to make an official determination
whether geographic jurisdiction exists over aquatic resources in the review area, or
to provide an official delineation of jurisdictional aquatic resources in the review area,
the Corps will provide an AJD to accomplish that result, as soon as is practicable.
This PJD finds that there "may be" waters of the U.S. and/or that there "may be"
navigable waters of the U.S. on the subject review area, and identifies all aquatic
features in the review area that could be affected by the proposed activity, based on
the following information:
