Drainage Assessment Modeling Phases I & II | City of Temple
Temple, TX
Project Summary: Phase I of this project encompassed Bird Creek and Friars Creek watersheds. This project included regional stream and regional pond models and recommended regional detention pond locations and sizes. In addition, KPA identified projects to mitigate structural and property flooding along creeks, projects to reduce roadway crossings at creeks, and updated National Flood Insurance Program (NFIP) Flood Insurance Rate Maps (FIRM). Proposed solutions to address inaccessible streams and creeks for city maintenance. In addition, KPA and city staff selected focus areas of concern related to properties flooding outside of creek flood plains.
Phase II of the project includes four additional stormwater runoff watersheds in Temple, Texas. The four watersheds comprise approximately 31 square miles of the study area and extend to the Extraterritorial Jurisdiction (ETJ). Work included regional detention pond models and recommendations for locations and approximate volumes, identifying projects to mitigate roadway crossing overtopping at creeks, and updating National Flood Insurance Program (NFIP) Flood Insurance Rate Maps (FIRM). Final deliverables included current (2019) and future (2030) anticipated hydrologic and hydraulic flood plain models in HEC-HMS and HEC-RAS formats, letter of map revisions (LOMR) for each watershed as approved by the Federal Emergency Management Agency (FEMA), updated watershed boundary map for each of the studied watersheds and opinions of probable costs (OPC) for mitigations projects based on limited, high-level preliminary engineering within a 10-year implementation window for budgeting purposes.
Scope of Services: Final deliverables included 2017 and future (2030) hydrologic and hydraulic flood plain models in HEC-HMS and HEC-RAS formats, an updated watershed boundary map for each of the studied watersheds, opinions of probable costs (OPC) for mitigations projects based on limited, and high-level preliminary engineering within a 10-year implementation window for budgeting purposes.
Shell Road Sidewalk Improvement Project | City of Georgetown
Georgetown, TX
Project Description: This project consisted of installing approximately 2,800 linear feet of 5’ sidewalk along Shell Road in Georgetown. This work consisted of constructing a new sidewalk that provided access along the project route, furnishing and installing pedestrian ramps, crosswalks, stop bars, and signage from the south of Rosedale Boulevard to Bellaire Drive and Sequoia Spur to the existing sidewalk south of Sequoia Spur located along Shell Road. The Contractor was Patin Construction, LLC of Taylor, Texas. The project began in March of 2020 and was completed in July of 2020.
Scope of Services: Preliminary Engineering, Final Design (Plans and Specifications), Opinion of Probable Cost, Bidding, Review of Bids and Recommendation of Award and Construction Administration
Construction Cost: $229,825
Nolan Creek Trunk Sewer Preliminary Design Report & Final Design, Phase I | City of Belton
Belton, TX
Project Description: Due to significant growth and development in the Nolan Creek Basin, portions of the trunk sewer were at capacity and a preliminary design report was initiated to determine the existing flows and ultimate capacity required for the basin.
In 2012, the existing 10” Trunk Sewer, from Water Street to the north, was determined to be at capacity and experiencing significant infiltration/inflow during rain events. Generally, this project included evaluation of the Nolan Creek Trunk Sewer, beginning at the BRA Lift Station, to determine the current capacity and condition of the wastewater line. RJN Group provided flow monitoring and manhole inspection services, which included 10 flow meters and 4 rain gauges monitored for 90 days. This provided the data necessary to determine the current base flow in the wastewater line and the magnitude of inflow/infiltration.
Scope of Services: As part of the Preliminary Design, the recommended ultimate capacity to accommodate the growth in the area was determined. The report also included preliminary alignment of Phase I Improvements, opinions of probable cost, a phasing plan, and project schedule for the replacement of the Nolan Creek Trunk Sewer.

Sparta Road Reconstruction Project | City of Belton
Belton, TX
Project Description: The Sparta Road Reconstruction Project was a multifaceted roadway rehabilitation project that included intersection improvements at Industrial Park Road at Main Street, intersection realignment and traffic signal modification improvements at West 9th Avenue and Main Street; geometric modifications and traffic signal modifications for vehicles and pedestrians at the intersection of Sparta Road and Loop 121 and the installation of a roundabout at the intersection of Commerce Drive and Sparta Road.
The reason for the multiple locations was to adequately address traffic issues that affected the overall patterns and safety in the general area leading to Sparta Road and the efficient construction of the Sparta Road work tasks. Street reconstruction and realignment construction were accomplished in order to improve traffic flow. The project consisted of a ten feet width hike & bike trail, storm drainage improvements, traffic signal modifications, 10-inch full-depth hot mix pavement, street lighting, tinted 8-inch concrete pavement, concrete curb & gutter, standard 8-inch concrete pavement, multiple pavement markings, and traffic signing installations and grass sodding at all four locations with respect to roadway capacity and safety features for the traveling public.
The completed facilities are functioning as intended and have met community goals and objectives.
Scope of Services: Final Design, surveys, bidding, coordination, and construction administration.
Construction Cost: $3,239,592
