Pi6.beca pi:/77 .ri3t32471-at ipgrzr eir szl,99eariimer49mvumgp* '414,-941 INTRODUCTION The Federal -Aid Highway Act of 1962 established the requirement for a continuing, cooperative, comprehensive (3C) transportation planning process carried on by the states and local governmental agencies and communities. To conform with this directive, the State of Texas, the City of Corpus Christi, Nueces County, San Patricio County, and the City of Portland entered into an agreement to cooperatively conduct the con- tinuing process of transportation planning. Such a process has been underway in one form or another since the early sixties. The primary pro- duct of the transportation planning process is a current transportation plan which is designed to adequately and safely accommodate forecasted traffic, in the study area, in a manner that is in agreement with the area's planned development and growth. The plan relates to all types of travel and addresses both short, and long-range transportation improvement programs. It is kept current by a continuing review process which evalu- ates any changes in travel pattern, land use, economics, and population. The present status of the transportation plan is reflected in this annual report. A review of the past year's accomplishments and an evaluation on the status of major projects now underway are presented, in order to determine the progress on the current phase of the transportation planning process. The changes that have occurred in the transportation plan are presented and the factors which were an integral part of its development are discussed. ORGANIZATIONAL STRUCTURE The transportation planning process in the Corpus Christi urbanized area requires a single-staffdirection for all modes of travel. In accordance with U.S. Department of Transportation guidelines, an organizational structure has been developed to provide for a Policy Advisory Commit- tee composed of locally elected officials and its Steering Committee and Technical Committees as may be necessary for the purpose of continu- ing the transportation planning process. This structure, consisting of representatives from area governments and agencies, has been formalized through the Corpus Christi Urban Transportation Study (continuing phase) agreement. Signatories to this agreement are the City of Corpus Christi City of Portland County of Nueces County of San Patricia, and the State Department of Highways and Public Transportation The single -staff direction in the transportation planning process is provided by the City of Corpus Christi as the Governor's designated Metropolitan Planning Organization, in cooperation with the State Department of Highways and Public Transportation. POLICY ADVISORY COMMITTEE The Policy Advisory Committee, with assistance of the Steering Committee and various technical committees, has the responsibility of provid- ing the policy direction necessary for continuing the transportation planning process in a cooperative and coordinated manner as prescribed by the continuing phase agreement. The Policy Advisory Committee includes the following voting members: One elected official representing the City of Corpus Christi One elected official representing the City of Portland One elected official representing Nueces County One elected official representing San Patricio County All locally elected U.S. Representatives, State Senators and State Representatives desiring to serve. Responsibilities of the Policy Advisory Committee, in addition to providing general policy guidance, shall include annually reviewing and adopting the transportation plan (revised as necessary); taking appropriate action on recommendations of the Steering Committee, including those relative to certification or re -certification; and meeting as necessary to perform its functions and hold a public meeting at least once a year to discuss the status of planning. STEERING COMMITTEE The Steering Committee is composed of the following voting members: Three representatives of the City of Corpus Christi One representative of the City of Portland One representative of the County of Nueces One representative of the County of San Patricio Two representatives of the State Department of Highways and Public Transportation Five locally elected State Officials (Those desiring to serve.) The Steering Committee will also invite additional nonvoting members that they deem necessary to promote the coordination between the agencies involved in the principal modes of transportation. The Steering Committee shall provide routine guidance to the planning process, examine the adequacy of the continuing planning process at ap- propriate intervals, and at least annually assign each agency responsibility for updating various study elements. The committee shall make a progress report from which an annual written progress report will be prepared and recommended to the Policy Advisory Committee any necess- ary revisions to the Plan. It shall determine whether the current transportation data is in accord with previous projections and recommendations or if there are discrepancies of a nature that would require significant changes in the Plan. In addition, the continuing phase agreement shall be reviewed annually to determine if it should be supplemented or renegotiated. The committee shall recommend action to the Policy Advisory Committee, review the Prospectus annually, and if necessary recommend revisions. It shall also review the limits of the Study Area, make any necessary minor revisions and designate such technical committees or task forces needed to carry out the planning process. A Planning Coordinator will be assigned by the State Department of Highways and Public Transportation to work in close cooperation with the cities, counties, and the Metropolitan Planning Organization.

Such a forecast can be used as indicator of future transportation needs and as a gauge of the future adequacy of existing transportation facilities. Between 1960 and 1970, the population in the Corpus Christi SMSA increased by 6.8%. It is estimated that by 1980, the population of the Cor- pus Christi SMSA will be 319,950, an increase of 10.9% from 1970. By the year 1990, the population figure will be 357,475, a 20.3% increase over the 1970 figure. ECONOMICS An analysis of the economic factors affecting the present and future development for the Corpus Christi metropolitan area is an important com- ponent of the transportation study. The various changes in the level of economic activity in the study area will provide the basic input for the land use and travel forecasts. EMPLOYMENT The Corpus Christi area economy is supported by tourist trade, agriculture, mining, manufacturing, construction, retail and service establish- ments, the U. S. Naval Air Station (N.A.S.), the U. S. Army Aeronautical Depot Maintenance Center, and the Port of Corpus Christi. The employment availiability within each of these activities is an indication of the growth of the activity itself. Between 1960 and 1970, total employment increased by 13.856 for a net gain of 16.8 per cern. However, growth was not spread evenly over all industrial sectors. Some industries experienced a decline. The largest growth in employment occurred in the industries producing services, education, health care, trade, repair and maintenance, government, transportation, communications, banking, etc. Employment in the good producing industries experienced a decline of 5.1 percent. The employment forecast for 1980 indicates that employment in the industries pro- ducing services will continue to grow, though not to the extent which occurred between 1960 and 1970. Employment in the good producing in- dustries will undergo a reversal of the 1960 through 1970 pattern, and will show an increase in employment. A total employment increase of 17% is forecast for the Corpus Christi SMSA, for the period between 1970 and 1980. INDUSTRIAL GROWTH The expansion of several major industrial plants in the area continued in 1976. Champlin Refinery proceeded with the expansion of its refinery and at the same time announce plans of its participation in the construction of a multimillion dollar ethylene production plant. The possible location of a deep draft inshore port at Harbor Island continued to be a important item of discussion in 1976. Such a facility would have a great influence on the economy of the area, particularly the local chemical, oil, and metal fabrication industries. CONSTRUCTION The construction industry showed a definite increase in 1976. Most of the activity was in the home building area, but commercial development also showed an increase. Further expansion of this activity is forecasted. MANUFACTURING The establishment of several manufacturing industries, has greatly increased the employment potential of this activity. Recent companies locat- ing in the area include Du Pont, Levi Strauss, Robstown Manufacturing Companies, Power Monolithics, and IHC Holland Le•rfourneau Marine Corp. Each of these industries is involved in a different activity, and each requires the support of other area industries which adds to it's employment potential. PUBLIC EMPLOYMENT There is a more than average reliance on Public Service employment in the Corpus Christi Urban Area, due to the existance of two large mili- tary facilities in the area. The Naval Air Station (N.A.S.), and the U. S. Army Aeronautical Depot Maintenance Center employ a substantial number of area residents. During 1976, the possible closure of the Naval facility emerged. Such a closure would definitely influence a large number of local industries. LAND USE A and use.analysis was done in the Corpus Christi Urbanized Area in 1963 and updated and expanded to include the City of Portland in 1973. The 1973 land use data was projected to a 1990 forecast year. The projected land use data was used in evaluating the present arterial system and in making traffic projections. The projected land use can be further used in selecting new major arterials and major thoroughfares in and around the study area. During the City of Corpus Christi continued to experience a steady growth in landrdevelppment. Residential construction continue( lead tht. „ories, with several multi -family complexes being established. Commercial uses also expanded, particularly in the southeast area the City. Development is generally in line with the projected land use forecast, except for a more intense commercial development along the Everhart and Weber arterials. TRAFFIC AND TRANSPORTATION STREET USE The mileage of streets and highways within the City of Corpus Christi has increased from 940 to 1,100 miles since 1964. The approximate mileage of streets and highways within the Corpus Christi Urbanized Area is 1,150. All the streets and highways within the study area are grouped into four basic categories. The four are: Principal Arterials, Minor Arterials, Collectors, and Local Streets. The greatest increase in total mileage of streets was due to the numerical increase in local streets. Though increases in the mileage of improved principal arterial and minor arterial roadways occurred, increases in mileage based on functional classification for this type of roadway were minimal. The Transportation Plan illustrates both the existing street uses throughout the Corpus Christi Urbanized Area, and the projected street func- tion in the year 1990. It is this master plan which is used in determining the location and design of roadway improvements. CAPACITY During 1976, a Capacity Analysis Study, was conducted on approximately forty intersections within the Corpus Christi city limits. Along with determining the present capacity status of these intersections, a comparison between the capacity of the intersections in 1964 and the capacity of the intersections in 1976 was made. This was done by comparing the congestion indices of the intersections, which is the ratio between the calculated capacity of the intersection and the peak hour approach volume. A congestion index of less than one is indication that some degree of congestion is present. Tables 4 and 5 under "Studies for Future Improvements," list the results of the 1976 Capacity Analysis Study. ACCIDENTS Traffic accidents are an undesirable by-product of vehicular traffic and may be used to measure how efficiently a particular street operates. Dur- ing 1976, as in previous years, an Accident Analysis Study was conducted for the Corpus Christi Urbanized Area. For the purpose of analysis, all accidents are divided into two categories. Accidents attributable to the influence of intersections on the principal network are classified as in- tersection accidents. Those accidents occurring between these intersections are termed control section accidents and include all minor intersec- tions not on the principal network. For 1976, the top 30 accident intersections were those listed in Table 1. Evaluation of the signal systems, capacity deficiencies, or geometrics of each of these intersections are conducted in an effort to determine the cause and minimize the occurrence of traffic accidents. In addition to evaluation of high accident locations, several special projects were masted to provide for special study of specific accidents. In cooperation with the State Office of Traffic Safety the following projects were undertaken: 1. Accident Analysis and Location Program - This project allows for the computerized storage and analysis of traffic accident data. It is used to quickly identify high accident locations and list probable causes. 2. -Blue Squad" - Special project which allows for concentrated police surveillance for motorist operating under the influence of alcohol and/or drugs. 3. "Red Squad" - Special project which allowed for concentrated police surveillance of violating motorist. Emphasis placed on illegal stops, change of lanes, and speeding. Thus, the -application of the principles of engineering, enforcement, and education are used as tools for the elimination and reduction of traffic accidents in the Corpus Christi Urbanized Area.

In an effort to improve transit services and reverse the trend of declines in passengers, the City hired a consultant to formulate a Transit Development Plan. The Plan was completed and accepted by the City during this past year. In addition, the following equipment was purchased in 1976: 1. Acquisition of 15 new 45 -passenger, air conditioned, diesel transit buses. 2. Acquisition of 35 two-way radios to provide direct communications between transit vehicle and home base. 3. Acquisition of 15 registering fareboxes. 4. Purchase of 15 bus shelters to be installed during 1977. 5. Purchase of 6 minivans, two of which are to be used for handicapped and elderly. Delivery of vans is to occur in 1977. BICYCLE ROUTES Bicycles are becoming evermore important in the mobility of the general public. Whether they are used as a means of travel out of necessity or recreation, planning for adequate bikeway facilities is an important part of the Transportation Plan. The City of Corpus Christi and the City of Portland adopted, during the past year, a comprehensive Bicycle Route Plan. The Plan is illustrated in Figure 3. It is designed to provide maximum mobility to cyclists throughout the City. Both off- and on -street bikeways are provided. SIGNIFICANT TRANSPORTATION EVENTS In 1976, several events occurred which had or will have a definite effect on the Transportation System of the area. They are the following - 1. Bayfront Science Park - Development of the Bayfront Science Park complex continued with the construction of the Community 'Theater and the Community Auditorium. Located on the extreme north end of the Bayfront, the complex also includes the .City Science Museum and South Texas Art Museum. At final completion, the area will be the site of a new Convention Center complex. Access to the complex and traffic circulation within the complex must definitely be considered in the Transportation Plan. 2. Ethylene Production Plant - Champlin Refinery announced plans during the past year, on the proposed construction of a multimillion dollar ethylene production plant. The site for the plant is located north of State Highway 44, between McKenzie and Violet Road. Its location necessitated that several changes be made in the 1990 Street Plan. These changes are listed and discussed in another area of this report. 3. Courthouse Facility - Construction of the new Nueces County Courthouse continued. The multistory structure is located in the up- town section of the Central Business District. Its construction is anticipated to spur the development of adjacent supplementary facilities such as restaurants, law offices and office services establishments. Access to and within the complex must be provided by the existing transportation facilities. 4. Northwest and Southeast Residential Growth - As anticipated, the southeast section of Corpus Christi continued to experience rapid growth/In residential development. New arterials, collectors, arid local streets were established throughout the area. Improvements to existing facilities were undertaken to alleviate congestion. Residential growth in the extreme northwest area of Corpus Christi began to emerge. Such growth has continued and expanded to include areas beyond the city limits. Traffic volumes on the principal arterial roadways serving the area increased significantly during the past year. TRANSPORTATION IMPROVEMENT PROGRAM The Federal Transportation Planning guidelines require that a Transportation Improvement Program (TIP) be developed by all areas involved in the transportation planning process. The TIP is a 3 -year listing of proposed improvements to the transportation system of the concerned area. It is composed of both short- and long-range improvements. The first year of the TIP is known as the Annual Element. It is a listing of projects anticipated to be performed and completed within the first year of the 3 -year program. The7nual Elements for 1976-77 are listed in Table 2, and those completed or under construction are shown in Table 3. Figure 2 is an illustration of the major roadway improvement projects which were proposed in the annual element for 1976-1977. The limits and status of each project is shown on the map.

The street network north of State Highway 44 between McKenzie Road (County Road 57) and Violet Road (FM 24) has been deleted. An ethylene production plant is being constructed on a 1200 acre site in the area. The western end of the proposed extension of McNor- ton Road as a thoroughfare will intersect as a "T" intersection with Violet Road, instead of a 4 -way intersection with County Road 44. The proposed thoroughfare north from the plant site to Haven Drive was downgraded to a proposed collector street. 2. Acquisition of land for the proposed airport expansion necessitated the elimination of the proposed "dog leg" in Buckholt Road. west of Corpus Christi International Airport, just north of its intersection with McGloin Road (County Road 34). 3. An existing railroad grade separation crossing of I.H. 37, between McBride Lane and Navigation Boulevard, was included in the Street Plan. 4. The Interchange of the Padre Island Expressway (State Highway 358) and Leopard Street was revised to indicate it as completed and "existing". 5. The double interchange for Agnes Street (State Highway 44) and the Padre Island Expressway was revised to indicate it as completed and "‘existing". 6. Carver and Cheyenne Streets were deleted as collectors. Both are now indicated as -local" streets. STUDIES FOR FUTURE IMPROVEMENTS Several studies were performed in 1976 that are to be used as a basis for developing future TIP programs. The most significant of these was the capacity analysis of approximately forty intersections within the City of Corpus Christi. The capacity deficient intersections for 1976 were iden- tified and are listed in Table 4. They are ranked in order of decreasing congestion indices. Congestion index (C.1.), as stated earlier in this report, is the ratio between intersection hourily capacity and intersection peak hour volumes. A congestion index figure of less than one indi- cates congestion is present. Table 5 is a listing of thirty intersections which were analyzed in 1964 and were found to have capacity deficiences. A comparison between the 1976 congestion index and the 1964 congestion index is illustrated. All of the thirty intersections have improved con- siderably in regard to capacity. The improvenents can be attributed to several factors, some of which are, improved signal systems, improved and widened roadways, or the availability of equal or better transportation facilities. 1976 CAPACITY DEFICIENT INTERSECTIONS CAPACITY IMPROVEMENTS OF 1964'S THIRTY MOST CONGESTED INTERSECTIONS Intersection Road of Travel Approach Time Everhan-McArdle Staples -Texan Trl.
