3 WBS No. N INTRODUCTION This preengineering study is prepared by PGAL for the (City) under the terms of the Contract for Professional Engineering Services for preengineering services for Kingwood Drive from Loop 494 to Woodland Hills, Project No. N The purpose of the study is to provide assessment of existing conditions, identify the needs, provide alternative solutions and recommendations for street and paving improvements, drainage concepts, water line and sanitary sewer utility improvements, and cost estimates. The project is located in northeast Houston (Kingwood area Key Map 336 A, B & C), (Council District E), between Loop 494 on the west and Woodland Hills on the east (See Location Map below). and HCFCD Ditch G ) is characterized by extensive retail and commercial development. Access to these developments is by signalized intersections and unsignalized intersections at driveways. The east segment (between the drainage ditch and Woodland Hills) is abutted by residential developments that have access to Kingwood Drive at major signalized intersections. Other than at these openings, this segment of road is characterized by fenced rightofway on both sides. The existing geometry of Kingwood drive generally follows the geometry of each rightofway line. As shown on existing conditions exhibits, the right of way varies in width from a minimum of about 125 feet to a maximum width of about 200 feet. The roadway follows each rightofway line creating a median of varying width. The medians are heavily wooded with the original trees before the development of the area. Areas adjacent to the inside curb of each roadway have been cleared to enhance sight distances. The profile of Kingwood drive is generally flat with the exception of the portion between Trailwood Village Drive and Big Springs Drive. In this area Kingwood Drive is raised to create clearance for a pedestrian crossing under it. There is one gated railroad crossing adjacent and parallel to LooP 494. Considering the enormous traffic volumes at the intersection of Kingwood Drive and Loop 494, a RR grade separation may be part of a future alternative solution. NEEDS IDENTIFICATION is evaluated in three major categories; Street and Traffic, Drainage and Utility Needs (Water and Wastewater). EXISTING CONDITIONS Kingwood Drive is the major east west thoroughfare thru Kingwood. It is currently designated as a principal 6lane thoroughfare with varying width rightofway. The roadway was built in segments by the developer of the Kingwood development and as a result, the age of the road varies along the alignment. The roadway is concrete boulevard section with storm sewer systems. Several portions of the existing pavement have been replaced or repaired and several small additions added left or right turns as well as left turn storage lanes at new signalized intersections. Development along the roadway differs in character between its west and east segments. The west segment (between Loop 494 The pavement condition rating (PCR) provided by indicates that the existing pavement between Loop 494 and Woodland Hills is in acceptable condition with an average rating of 62. As mentioned earlier, the existing pavement has been heavily repaired and widened at places. It is clear that it is beyond its intended life span and it still shows signs of significant longitudinal joint deterioration and or failure. The physical deficiencies noted include lack of sidewalks along the western segment, wheelchair ramps at cross streets that do not meet current standards, narrow sidewalks across the drainage ditch bridges and lack of sidewalks connecting the trail system that exists along the eastern segment of the road and the cross streets to allow safe crossing of Kingwood Drive at these locations.

4 WBS No. N Kingwood Drive Bridge over HCFCD Ditch G is a tandem 146ft, 4span prestressed concrete Tbeam bridge on prestressed concrete pile trestle bents, built in A visual structural inspection was performed to determine the general conditions of the bridges. Based on the evaluation, the twin bridges are in sound condition. The preliminary LOS show LOS "F" along the entire corridor for the existing condition. The future traffic assignment on Kingwood Drive for the year 2035 shows an ADT of 54,955 from Loop 494 to Woodland Hills. HSC results show LOS "F" along the corridor assuming no capacity improvements for year The project limits lie in San Jacinto River watershed and existing drainage is provided by six storm sewer systems that serve a total area of 274 acres. According to the record drawings and GIMS, the storm sewer systems were built in Since then significant development has occurred in the area that was not reflected in the asbuilts but shown in GIMS. Several cross streets (Royal Forest Drive, Green Oak Drive, Ladbrook Drive, and Woodland Grove Drive) and median openings have been constructed. This development has resulted in additional curb/grate inlets, manholes, and laterals draining water from parking lot areas into the trunkline. Record drawings for drainage system G0208 were not located; however, information exists in GIMS. The system generally consists of B and BB type inlets at the end of curb returns in side streets and storm sewer pipes ranging from 18 to 66inch in diameter. Of the six systems, two are unable to convey the 2year storm event according to the Comprehensive Drainage Plan (CDP). There have been 2 structural flooding complaints for the system. Kingwood is served by 16 and 12 waterlines from Loop 494 to Woodland Hills. The City has requested a number of improvements and replacements along the project. All of the sanitary sewers are located in neighborhood streets except for one short segment between Royal Forest and Chestnut Ridge. CenterPoint Energy (CPE) provided gas and electric utility maps as logged under CenterPoint Energy ID There are two gas lines were identified within the Kingwood Drive Street RightofWay. A 4 HP STL Gas Line along Kingwood Drive from Loop 494 to Trailwood and an 8 IP STL Gas Line along Kingwood Drive from Trailwood to Woodland Hills Street lighting in the project area is provided by cobrahead light fixtures on metal poles between Loop 494 and Woodland Hills Drive. There are no overhead power lines in the study limits. The communications facilities are provided by Suddenlink. Record drawings of their facilities were requested but have not been received as of yet. There are no existing pipelines in the project area. PROPOSED ALTERNATIVES Two alternative solutions were developed for Kingwood Drive. Based on the analysis of the traffic evaluation an 8lane solution is required to provide an acceptable level of service in the corridor. This alternative will generally require the complete removal of most of the existing forested median along the corridor. This alternative generally maintains the south curb line of the existing roadway. In areas of wide rightofway, both outside curb line were generally maintained. In areas of restricted rightofway the section was developed by maintaining the south curb line and allowing the north curb line to move towards the hike and bike trail rightofway. No additional rightofway is proposed in these areas even though the proposed curb is very close to the existing rightofway line. The existing trail is generally well away from the proposed curb, so no modifications to it will be required. A 6lane alternative was also developed, to provide an option that although does not provide an acceptable level of service during the design life of the project, it might prove more acceptable to the affected stakeholders. This alternative generally maintains the location of the outside curbs along both sides of the roadway and widens the pavement towards the middle. Both alternatives will require the widening and or reconstruction of the existing bridge. Even though the evaluation of the existing structures did not reveal any structural deficiencies that would dictate the reconstruction of the bridges, both will require widening under either alternative and as such it is recommended that the bridges are reevaluated during design. CANDIDATE PROJECT DEVELOPMENT Each project solution was evaluated in order to determine their merits and ranking among the project alternatives and eventually the ranking of the recommended alternative to other projects citywide based on the project priority score.

5 WBS No. N The estimated cost of the 8lane alternative is approximately 31,077,000. The estimated cost of the 6lane option is approximately 27,299,000. RECOMMENDATIONS The 8lane alternative with inline detention is recommended for implementation. Based on the projected traffic and the difficulty in identifying any available locations for detention ponds, it was determined that the best alternative is to construct a facility that will be able to accommodate the traffic for the design year and to enlarge the proposed storm sewers to provide the required detention. The existing traffic suggests that implementation of the 6lane alternative will necessitate the planning and construction of widening to 8 lanes very shortly after rebuild to 6 lanes is completed. If implementation of this alternative proves impossible due to the significant impacts on the trees and public opposition, it is recommended to proceed with the 6lane alternative. The total project cost of this alternative is 27,299,000. The calculated score of this alternative is The total project cost of the recommended alternative is 31,077,000. The calculated score of this alternative is PGAL Page 3
