PROJECT JUSTIFICATION: This project provides the means for extending Departmental objectives to highway and pedestrian facilities not on the Federal-aid system, The justifications and locations of work to be performed under this project are contained on the succeeding 5 pages.
SCOPE OF WORK OUTLINE: Constructing curb and gutter; covering existing roadway surfaces; constructing and replacing side- walks; grading and improving unpaved streets; installing traffic control facilities; constructing alleys; building drainage and minor structures; and
improving Urban Renewal and Code Enforcement Areas.
Curb and Gutter: $388,000
The funds requested are for the construction of curb and gutter and the repair or construction of roadway pavement. It includes reclamation and modernization of old roadways and streets to provide better drainage and parking which are a part of "city type" street work, and relocation and realignment of curb and gutter at various intersections. It is proposed that the following streets be improved by this method in 1972.
The funds requested for cover work will be used for surfacing deteriorated older streets in order to provide a watertight cover. This prevents water from gaining access to the subgrade which would result in rapid deterioration and increased maintenance costs, and necessitate and earlier replacement of the existing pavement. This type of work extends the life of the pavement by 10 to 15 years and provides improved riding conditions at a minimum cost. The following streets are proposed for this type of improvement during 1972.
Hayes St., 55th St. to 56th St...... Kearney St., 13th St. to 14th St.... 50th St., Grant St. to Hayes St.
The funds requested are for the new sidewalks and alleys under the assessment system, and the construction of sidewalks and curbs around public reservations, municipal and Federal buildings. Sidewalks and alleys abutting private property are paved upon the request of the property owner.
Work under this allocation will be apportioned approximately as follows:
Sidewalks, curbs and alleys (abutting National Capital Housing)
Sidewalks, curbs and alleys (abutting
D. Grading and/or Improving Unpaved Streets: $10,000 The funds requested are to cover the cost of general grading in connection with new building construction, sewer and water line installation, opening of new streets and alleys and to rectify drainage conditions. Funds are also provided to improve newly graded streets with a low cost type of pavement, generally macadam or surface treated gravel.
Agency Highways and Traffic
New industrial and residential construction requires the opening of new streets which must be improved to allow access. The locations are in all sections of the District. A tentative list of locations cannot be furnished in advance because exact locations of proposed construction is not known.
Work under this project will be done either by contract or force account, whichever is deemed to be in the best interest of the District.
Traffic Control Facilities:
The funds requested are to provide for the design, engineering and installation of new traffic control devices and the modernization of existing controls. It is anticipated that approximately forty new locations will be signalized during the 1972 Fiscal Year. The continually increasing volume of traffic within the District of Columbia, the impact of Freeway and Metro construction, and the changing pattern of street usage due to Urban Redevelopment requires that our program of design, installation and provision for more traffic responsive controls be continued. Such a system is needed to reduce unnecessary delays, improve safety, provide for special turning movements, provide for two signal indications for each approach, and bring the entire signal system into conformance with the provisions of the Manual on Uniform Traffic Control Devices for Streets and Highways,
It is necessary to continue the modernization and replacement of the traffic control system equipment now in service in order to regulate and change the

fixed time traffic signal sequences during peak hours and emergencies. It is essential that this signal improvement work be performed on a continuing basis in order to utilized the full capacity of the existing master controller.
Continuing studies are necessary in order to program the long range conversion to a fully traffic responsive signal control system. Such a system will provide for maximum responsiveness to change in traffic demands throughout the District of Columbia. An area of approximately 200 intersections is under a special study by the Federal Highway Admin, in cooperation with the Department of Highways and Traffic for developing a fully traffic responsive system using computers.
The program of purchase and installation of "blank-out" illuminated signs is to be continued, These signs are installed at intersections where certain turning movements are prohibited during rush hours, where lanes or entire roadways are reversed during peak periods and where specific traffic prob- lems require automatically opening and closing traffic lanes. These signs are illuminated during the hours that the prohibition is in effect and must be responsive to emergency traffic conditions such as early dismissal of schools or Government personnel, detours and special events. A number of these signs have been installed to date and they have proven very effective in promoting safe and efficient traffic movement.
In addition, flashing signs with a more positive message, and operating only at the times when children
are going to and from schools, are very effective in alerting motorists approaching schools on arterial streets of the legal speed limit. A program to connect these flashers to the Master Radio Control System is order to provide remote control operation, and to in- stall these flashers at 20 additional locations along major arterial routes adjacent to schools, will be continued.
Sidewalk Replacement: The funds requested are for the continuation of a program initiated in Fiscal Year 1962. The intent of this program is to replace deteriorated defective and unsafe sidewalks in the District of Columbia. The side- walks have deteriorated in recent years mainly due to the effect of tree roots causing cracking and upheaval of the pavement. At the start of this program, it was estimated that approximately 15% of the existing side- walk yardage was in need of replacement, and progress has been made toward reducing this backlog.

The funds requested are to provide for the construction and/or reconstruction of drainage structures where no major street improvement is necessary. This work is chargeable to the Highway Fund since its pur- pose is to provide proper drainage of surface water from public space. The work consists of installation of culverts, catch basins and connections.
The northwest area of the city bounded on the north by New York Avenue, on the east by North Capitol Street, on the west by Third Street, and on the south by Massachusetts Avenue, has been designated as an Urban Renewal Area. The main activities proposed for this area will be residential redevelopment and re- habilitation of existing housing for middle income families, and public housing for low income families.
The redevelopment of this area will involve the closing of some streets and alleys, the repaving of others and the creation of new alleys and walkways. The funds requested in Fiscal Year 1972 cover the costs of the Department in this area. These costs are:
