Street and Drainage Information

Street Information - Phase I of the City's CIP

• Updated Streets CIP – December 2021
  • City Council in December 2021 approved the updated Street's CIP. The City of Castle Hills has invested in nearly $4 Million in new street infrastructure and close to $500,000 as part of the street maintenance program to protect the integrity of the City’s Street through these efforts over the last three years.  In the Fall of 2018, the condition of the City of Castle Hills streets was assessed. The report indicated that that only 22% of the streets were in “Good Condition”, today this number is closer to 64%.  This percentage will continue to increase as we start Phase II of the City of Castle Hill’s Street Reconstruction Project which includes Shalimar, Briarcliff, Bluet and Wottlin. The assessment, the Capital Improvements Plan revealed 50% of all the streets in Castle Hills were in the “Reconstruction Category”.  To repair the streets within the “Reconstruction Category” is estimated cost of $10 Million. City Council is looking at the feasibility of securing funding to address the rest of the streets in the “Reconstruction Category” using Certificates of Obligations in the amount of $4 Million. RPS Engineering did further updates to the City's Capital Improvement Plan in August 2022.
• Capital Improvement Plan Phase 1 originally adopted in November 2018 - Streets - Castle Hills CIP Report
  • A five-year Capital Improvements Plan (CIP) is a planning tool to help the City forecast the timing and funding of future capital projects. The Plan is reviewed and should be as part of the updated annual budget process. Projects are prioritized and planned within the five years and the proper funding is allocated annually. The City of Castle Hills has needed a long-term plan to address streets and other infrastructure issues in the community. The CIP – Phase I – Streets provides a roadmap for the City which is an objective plan, quantifiable, and ultimately removes the politics from the equation. These reasons allow projects to continue without impact from elections. This offers citizens transparency and a non-partisan fact based path to maintaining, repairing, and constructing infrastructure. This document allows the City to coordinate projects with other entities, like SAWS and provides a basis for formulation of possible bond programs. The CIP provides total magnitude of infrastructure needs and includes an inventory, evaluation and maintenance/CIP recommendation for approximately 27 miles of asphalt roadways. Phase II of the CIP is underway and will encompass the drainage needs for the community.
  • Street Maintenance Program (SMP) –  The City identified street candidates and developed a list of street segments to include in the 2019 SMP. The 2019 SMP for Seal Coat Projects will include, but not limited to, approximately 29 different streets segments and 4 alleys for an approximate total length of 9.28 miles. In 2020, the City conducted micro-surfacing for over ten streets. In 2021, the City micro-surfaced over seventeen streets as part of the maintenance program.

Drainage Information - Phase II of the City's CIP

• In March 2019, City Council approved the second phase of the CIP for Drainage. Phase II - Drainage encapsulates all of the City of Castle Hill’s identified watersheds with an updated cost and prioritization schedule to address flooding in the community. The second phase for drainage identifies a need of $18 million within the five watersheds and outlines all projects, identifies needs, probable cost and provides a prioritization schedule over a five-year period. Phase II Drainage CIP

Master Drainage Study

• Master Drainage Plan – Phase 1 - Master Drainage Plan – Phase 1
  • The City of Castle Hills had a master drainage study completed in August 2015 (Phase I – Watersheds II and III) to identify a conclusion and recommendation to address drainage projects within the City of Castle Hills. The study indicated problem areas in watershed II and III. In watershed II, Dogwood Lane and the drainage ditch from North Manton/Lockhill Selma to West Avenue near Krameria Drive were identified. Specifically, the study provided a summary of improvements for Dogwood, East Castle, Wisteria, Mimosa, and Krameria. The study details significant improvements which are required in watershed II and III. In watershed II, it highlights the need to address the insufficient channel and culvert conveyance capacity through East Castle, Wisteria, Mimosa, and Krameria. The improvements call for an upgrade of the culvert for conveyance capacities and construction of a wider channel with concrete lining. Watershed II costs at the time of the report was estimated at $3.5 Million. In watershed III, the issue is insufficient drainage conveyance capacity along Carolwood through Banyan, the recommendation is to install an underground stormdrain system in order to convey the stormwater from Glentower to the existing outfall.
• Master Drainage Plan – Phase 2 - Master Drainage Plan –Phase 2
  • The City of Castle Hills had a second master drainage study which was completed in May 2016 (Phase II – Watersheds I, IV and V) to identify a conclusion and recommendation to address drainage projects within other watersheds in portions of Castle Hills. The purpose of this study was to determine the cause of flooding within primary waterways with watershed I, IV and V (Fox Hall, Lemonwood, Travertine and Atwater). Similar to the first master drainage plan, phase II the Drainage CIP outlines proposed improvements with a scope of work and probable cost.
