3. Project Description
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 project is located on an unnamed tributary of Crabtree Creek. At 312 Ramblewood Drive an existing 18 inch pipe
crosses the roadway and due to its current size is restricting flow and causing structural flooding at 312 Ramblewood Drive
and righ of way flooding. North Hills Mall and Interstate 1-400 comprise approximately 2/3 of the 20 acre watershed with the
remaining 1/3 of the land use as single family residences to the 18 inch pipe. The project begins at the right of way of 1-400
where an existing 36 inch pipe crosses 1-400. A small channel has formed downstream of the pipe however the area has not
been maintained and debris and sediment has impaired the active channel. The channel becomes more defined
approximately 100 feet downstream and continues to enlarge and deepen until it enters an 18 inch pipe in the back yard of
312 Ramblewood Drive. The pipe extends approximately 60 feet and ends at the east side of the house. The pipe discharges
into an existing 70 feet long channel that terminates at the existing 18 inch pipe street system. The 18 inch street collection
system exits on the south side of Ramblewood Drive and enters an existing stream that continues approximately 112 linear
feet to the property line at 312 Ramblewood Drive where the project ends. The stream within the project limits are at a
minimum intermittent. The stream buffer north of Ramblewood Road is wooded but narrows in places due to existing
maintained residential lawns. The stream on the south side of the stream has a wooded buffer as the existing house is set
back an extended distance from the street.
3b. List the total estimated acreage of all existing wetlands on the property:
None within the disturbed limits of the project.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
464 Linear feet
3d. Explain the purpose of the proposed project:
The project was requested by the property owner at 312 Ramblewood to address structural flooding that is occurring due
to the inadequate street pipe system. An additional concern was presented by the property owner at 300 Ramblewood
Drive to address the stream degradation issues and flooding of his shed that is occurring in his rear yard which was
incorporated into the project. The project will reduce flooding at 312 Ramblewood through the removal of the 18" inch
pipe in the rear yard and upsize the pipe system to a 48 inch pipe at the street. Stream restoration is also planned to
improve stormwater and sediment transport behind 300 Ramblewood Road and stabilization measures on the
downstream side of the upgraded system.
Page 4 of 14
PCN Form —Version 1.3 December 10, 2008 Version
3e. Describe the overall project in detail, including the type of equipment to be used:
The project is primarily a street pipe system upgrade however; the project was expanded to address stream issues upstream
and downstream of the roadway. The upstream limit of the project begins at the 1-440 right -of -way. From the right -of -way
approximately 87 linear feet of stream will be restored in which the dimension, pattern, and profile will be improved.
Debris in the buffer will be removed and the area re- graded to improve flow. The stream's sinuosity will be improved and
constructed riffles will be installed to provide vertical stability. The buffer will be replanted with herbaceous and woody
species. Continuing downstream and just below the restoration area no improvements will be made to the existing
channel for approximately 171 linear feet. The channel within this reach is currently incised but stable and is in a heavily
wooded area.
Stream improvements will begin again at the existing 18 inch pipe that originates in the rear yard of 312 Ramblewood Drive.
This existing pipe will be removed and approximately 112 linear feet of stream will be restored back to a natural channel.
The stream in this area will contain a bankfull channel and the adjacent area will be graded to accommodate larger storm
events and convey the water away' from the existing structure. The channel will be constructed with a sinuous alignment
and constructed riffles will be installed to provide vertical stability within this reach. The stream bank will be replanted with
herbaceous and woody vegetation.
The existing 65 linear feet of stream channel immediately downstream of the day lighted channel segment will have bank
improvements and the channel will be widened to accommodate the entrance to the proposed drop inlet. Riprap will be
placed at the drop inlet structure entrance for grade and erosion control. The drop inlet will be the entrance to the
proposed larger pipe system crossing Ramblewood Drive. Additional inlets in the roadway are included as a part of the
system upgrades to relive street flooding.
The proposed 48 inch pipe exits into an existing stream on the south side of Ramblewood Drive. To construct the
proposed pipe a large tree near the roadway will need to be removed. This area has scoured out and the existing tree
roots are currently holding the bank and driveway. The proposed pipe headwall has been extended to allow for the area
from the top of the retaining wall to the roadway to be backfilled and replanted with woody vegetation providing stability
for the driveway. The wall will also provide protection from scour from the stream. To prevent scour on the stream bank
and the toe of the retaining wall rip rap will be placed on the bank of the pool area and the terrace bank. Boulders are
planned to be installed downstream of a rock waterfall where current bank erosion is evident. Grading of the south terrace
bank is proposed for a 40 foot stream segment at the end of the project to reduce velocities from large storm events that
will enter the adjacent downstream property. Buffer zones 1 and 2 will receive supplemental woody plantings and
herbaceous seed.

61- The buffer impacts at this location include grading and floodplain debris removal for the construction of the stream
restoration. The area will be replanted with herbaceous and woody vegetation.
132- The buffer impacts upstream and downstream of the pipe to be removed at 312 Ramblewood will include temporary
access in the buffer for construction equipment. The area will be replanted.
133- The buffer impacts include increases in the stream channel dimension and grading of the new stream banks. The banks
will be replanted.
64- The impacts in the buffer at this location will be for temporary construction equipment access.
135- The buffer impacts at his location include proposed grading and the replacement of an existing pipe headwall with a
elongated retaining wall. The retaining wall will be backfilled and woody vegetation established on the reconstructed bank.
This area has scoured out and is close to undermining the existing driveway. The backfill will assist in stabilizing the driveway.
The top of the retaining wall that will be exposed above grade is approximately 9" and extends for approximately 35 feet in
length (26 sf).
136- The buffer impacts in this area will be in getting construction equipment into the project site to make the repairs. Access
has been designated to avoid as many trees as possible in the buffer. The buffer will be mulched or replanted.
137- Grading of the terrace bank is proposed in this area to reduce the velocity in large storm events downstream.

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 upgrade of the pipe system can not be avoided because due to the restrictive pipe sizes at Ramblewood Drive structural
flooding is occurring upstream. The original goal of the pipe upgrade project was expanded to address stream concerns both
upstream and downstream of the project so that the total conveyance system improvements were addressed in the design.
The stream restoration work at the top of the project was added to improve stream function. The stream restoration will
improve the channel pattern profile and dimension increasing sediment transport and function. Natural channel design
techniques such as constructed riffles have been incorporated into the stream design. With the removal of approximately 100
feet of 18 inch pipe, 112 linear feet of channel was able to be restored as a part of the project. Upgrades to the stream at the
outlet of the improved pipe system have only been designed at high areas of stress in the system. Additionally the entire
floodplain will be enhanced with woody species to promote long term stability. The improvements to the buffer through riparian
seed and woody plantings will improve habitat and water quality throughout the project length.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The limits of disturbance have been set to minimize damage to existing trees and vegetation adjacent to the stream and in the
buffers. The proposed construction will minimize proposed impacts by pumping around any base flow withing the restoration
areas and performing all construction from the top of the stream bank in all other areas of the project. Construction equipment
will not be allowed to cross an active stream. Natural stone material will be used in the structures to be constructed in the
stream to promote aquatic species habitat and vegetation will be used on the stream bank for long term stabilization.
