Chairman Linda W. Cropp, at the request of the Mayor, introduced the
following resolution, which was referred to the Committee of the Whole.
To approve the Klingle Road Use Plan submitted to the Council by the
RESOLVED BY THE COUNCIL OF THE DISTRICT OF COLUMBIA, That this
resolution may be cited as the "Klingle Road Use Plan Approval
Resolution of 2002."
Sec. 2. Pursuant to the Title XXXIV of the Fiscal Year
2003 Budget Support Act entitled "Council Review of the Planned Use
of Klingle Road, NW," the Mayor transmitted to the Council a
resolution for Council approval of the Klingle Road Use Plan.
Sec. 3. The Council approves the Klingle Road Use Plan
and finds that:
(1) This submission meets the deadline of December 31,
2002 and the plan requirements of Title XXXIV, section 3401 et seq.
(2) Klingle Road, NW, was closed to vehicular traffic
in 1991 from Courtland Place on the west to Porter Street on the east.
(3) An exhaustive review has been conducted by DDOT of
possible options in the Klingle Road Feasibility Study ("The
Study"). The Study, which evaluated seven alternatives for the
management of the approximately 0.7 mile of roadway, assessing impacts on
the biology, water resources, traffic, socioeconomic and cultural
resources, resulted in the Klingle Road Use Plan.
(4) The Klingle Road Use Plan includes the following
elements as indicated in the attached documentation:
Sec. 4. The Council adopts the fiscal impact statement in the committee
report as the fiscal impact statement required by section 602(c)(3) of the
District of Columbia Home Rule Act, approved December 24, 1973 (87 Stat.
813; D.C. Official Code § 1-206.02).
(a) The storm water runoff and drainage problems in
Klingle Valley will be evaluated in a hydraulics and hydrology study
that will be used to develop the Storm Water Management Action Plan. The
Study, described in Attachment 1, includes determining the boundaries of
the drainage basin, measuring the volumes of storm water runoff and
developing methods to channel storm water to minimize environmental
(b) Based on the findings of the Storm Water
Management Plan, the District Department of Transportation (DDOT) will
develop a series of surface stabilization measures. In consultation with
the Federal Highway Administration (FHWA), National Park Service (NPS)
and DC Department of Health (DOH), DDOT has developed a preliminary set
of Immediate Stabilization Measures, as indicated in Attachment 2. This
will be adjusted, if indicated by the quantitative analysis of the storm
(c) An Environmental Assessment (EA), detailed in
Attachment 3, will be carried out once the Council approves the Klingle
Road Use Plan. The EA, based on the Klingle Road Feasibility Study, will
be guided by policies of the National Environmental Policy Act (NEPA),
the Council on Environmental Quality (CEQ) and FHWA. Local and federal
agencies will be consulted to identify all environmental issues and the
public will be fully involved. Once the EA is approved, DDOT will
proceed with design and construction of the approved facility.
(d) The East/West Transportation Study, detailed in
Attachment 4, will investigate possible mitigating measures for
east/west traffic congestion. The study will assess east-west travel
needs generated by Connecticut, Massachusetts, Wisconsin, Georgia and
New Hampshire Avenues and Military Road. It will analyze current and
projected traffic, including increases in east-west trips due to retail,
residential and commercial growth and because of changes in travel into
and out of the District.
Sec. 5. This resolution shall take effect immediately.
Attachment 1: Storm Water Management Plan
The consultant will evaluate the impact of the storm
water runoff within the Klingle Creek water-shed pursuant to approved
Federal Highway Administration (FHWA), the National Park Service (NPS) and
DC Department of Health (DOH) guidance. The study will examine the
measures required to control storm water and support the creation of an
Immediate Stabilization Measures. The proposed study will also support
development of a proposed project description and an analysis of the
impacts of the proposed project in a future National Environmental Policy
Act (NEPA) document.
Characterization and delineation of Klingle Creek
watershed. The Klingle Creek watershed will be delineated into several
drainage basins for simulation of runoff and identification of
potential problem areas. The boundaries of these basins are based on
the topographic features of the watershed.
Characterization of land use conditions. The
existing land use conditions in Klingle Creek watershed will be
identified and characterized based on available Geographic Information
System (GIS) land use/land cover data and recent aerial photography of
the watershed. Maps of both data types will be developed and overlaid
to check for quality and accuracy.
Characterization of the Klingle Creek channel and
the bank condition. A field assessment of Klingle Creek will be
conducted to determine the channel type and estimate the length,
slope, width, and depth. Field observations will be made on the
conditions of the channel bed and the stream bank stability.
Identification of existing sewer infrastructure
within Klingle Creek watershed. The Klingle Creek watershed is located
within an urban area that is served by sanitary and storm sewers. The
general alignment of the existing sewer systems will be identified and
mapped based on the available maps of the study area.
Identification of storm drain outfalls and existing
problems in the storm water conveyance system. Storm water outfalls
discharging storm runoff to the Klingle Creek watershed will be
identified and the areas of the watershed contributing this runoff
will be identified from drainage maps and field observations.
Development of a HEC-1 model of the watershed.
Using the Hydrologic Engineering Center Model (HEC-1, see below) model
to estimate the quantity of the runoff from the watershed and in
Klingle Creek Valley, the storm runoff will be routed though the
existing storm sewer system and the stream network.
- Development and evaluation of potential alternatives. Estimate
velocities for the predicted flows and stream cross-sections at
selected locations. Develop solutions to provide a basis for
estimating differences in the potential for stream bank degradation.
Detailed tasks to complete the hydraulic analysis and storm water study
1. Gather and review data and information for study area
Previous reports or studies conducted in the Klingle Creek or Rock
Creek watershed will be reviewed and considered. Data and information
published in reports such as the following are of great importance where
- Rock Creek Watershed Conservation Study
- District of Columbia Municipal regulations
- Infiltration/Inflow Analysis Rock Creek Sewer System Drainage Basin
- Infiltration/Inflow Analysis Drainage Area No. 3
- Effects of Urban Development on Floods in Northern Virginia
- Effects of Urbanization on Stream flow and Sediment Transport in the
Rock Creek Park and Anacostia River Basins
- Channel Profile Existing Road Profile
2. Watershed delineation and land use characterization
The limits of the Klingle Creek watershed will be based on the 1991
National Capital Planning Commission 1991 topographic maps of the District
of Columbia at 1:2400 scale. The land use conditions will be based on
existing data and verified through visual field observation.
3. Characterization of the Klingle Creek channel and bank conditions
Assessment of the existing Klingle Creek channel and bank conditions
will be based on visual stream assessment. The visual assessment will
include the items listed below and the problem areas will be identified
- Channel conditions (geomorphology)
- Bank stability and vegetative protection
- Riparian conditions
- Stream habitat diversity
- Riffle frequency and embeddedness in run areas (high gradient
- Pool variability (low gradient streams)
- General water quality characteristics
- Evidence of dumping, debris and illicit discharges
- Obstructions to flow
- Position of pipes and drainage ditches
- Storm drain outfalls and ponds
- Location and conditions of road crossings
- Location of utility lines
4. Identification of the storm sewer system infrastructure in Klingle
Identification of the trunk line into which the sewer collectors
discharge will be based on review of maps from Water and Sewer Authority (WASA).
The sewer line will be digitized and included in the GIS model of the
Klingle Creek watershed. The existing storm pipes will be evaluated using
measures such as smoke testing, and/or televising the lines.
5. HEC Model developments
Input files for the Hydrologic Engineering Center Model
(HEC-1) will be developed. The model will be used to process rainfall data
and to generate hydrographs based on the rainfall data and the watershed
characteristics. This model will provide the volume and velocity of flow
at all the contributing subareas. The HEC-RAS (River Analysis System)
model will then be utilized to develop water profiles within the creek and
to perform scour analysis and sediment transport analysis. The HEC-1 and
HEC-RAS models will be calibrated based on historical stream flow data
from a representative stream flow gage.
6. Development and evaluation of proposed stormwater management
The storm water runoff will be routed through the
existing storm and the stream network. Runoff volumes and velocities will
be evaluated for the 1-year, 10-year and 25-year design storms.
Alternative solutions will be developed to minimize the flooding and
erosion which is occurring in the Klingle Creek valley. These alternatives
will also be designed to improve water quality by reducing the scouring
that is occurring within Klingle Creek without negatively impacting the
downstream waterbody, Rock Creek.
Alternatives to be developed will include:
- routing portions of the stormwater flow entering the valley around
Klingle Creek to Rock Creek,
- slowing the velocity of flow at the stormwater outfalls,
- detention and/or retention of stormwater within the valley or
surrounding area, and
- slowing the velocity of flow in Klingle Creek via an engineered
All alternatives to be developed will include proper
outlet protection at outfalls to prevent scour and erosion. All culverts
and pipes will be analyzed based on the design storm required by Federal
and local regulations.

Attachment 4: East-West Transportation Study
In August 1999, the District Division of Transportation
(DDOT) retained Louis Berger, Inc., a consulting firm, to perform a
feasibility study for seven different options for the use of the portion
Klingle Road closed in 1991 due to the deterioration of the roadway.
Options ranged from No Action to rebuilding Klingle Road to accommodate
vehicular, pedestrian and bicycle uses.
The Feasibility Study identified traffic problems in
the area surrounding Klingle Road, including unacceptable levels of
service, roads operating at or near capacity and delays at signalized
intersections and approaches during peak periods. Problem roadways in the
vicinity include Connecticut Avenue, Garfield Street, Cleveland Avenue,
Woodley Road and Porter Street. All of the "build" alternatives
studied had both beneficial and negative impacts on traffic on these and
other nearby streets; none posed actual solutions to the area's existing
traffic problems and congestion. Whatever option was chosen, traffic
problems remained, often shifting from one intersection to another.
Much of the public comment included in the Feasibility Study called for
improvements in eastwest travel in the northwest quadrant of the city. For
many, the larger issue was not primarily the future of Klingle Road, but
the need to provide adequate east-west travel options through Rock Creek
Park and northwest Washington and relief for major arterials, such as
The East-West Transportation Study, which will assume
that the segment of Klingle Road between Cortland Place and Porter Street
remains closed to vehicular traffic, will be the first step in relieving
The East-West Transportation Study for northwest will take on the
- Characterize traffic conditions in the study area;
- Determine if the number of east-west trips in the northwest quadrant
will increase substantially in coming years, and by how much, due to
economic development, retail, and commercial growth, or due to an
increase in traffic to and from the District using this route;
- Investigate and develop methods for enhancing east/west mobility;
- Investigate congestion relief on existing roads not meant to
accommodate east/west mobility; and
- Develop ways to provide high quality transportation service east and
west of the District.
- Develop recommendations:
- Short-term to be implemented in one year or less;
- Long-term that will take longer than a year to implement.
- Submit cost estimates for each recommendation.
To address east-west travel needs and problems in Northwest Washington,
the study area will go beyond the limits of Klingle Road. At a minimum,
the area will include Dupont Circle, Massachusetts Avenue, Wisconsin
Avenue, Military Road, Georgia Avenue, Florida Avenue and New Hampshire
