City of Lubbock 11 ac Feasibility Study

Legacy Engineering was approached by a regional developer to evaluate whether a proposed property in Lubbock, TX could be successfully transformed into a profitable residential subdivision. The goal of the study was to provide clear, data-driven guidance on layout options, infrastructure needs, and overall development viability before the client proceeded with land acquisition and design.

Iterative Lot Layout Development

Over the course of the feasibility study, Legacy Engineering evaluated two major subdivision layout iterations, each responding to the unique geometry of the site, surrounding roadway network, and utility constraints. These early concepts explored:

• Street alignments and block lengths

• Cul-de-sac feasibility

• Lot width and depth optimization

• Connectivity to surrounding development

• Utility easement impacts

After reviewing each option with the developer, the team refined the preferred layout into a final optimized concept, maximizing the number of marketable lots while maintaining compliance with City of Lubbock development requirements and typical subdivision design standards.

Utility, Sewer, & Infrastructure Analysis

As part of the feasibility package, Legacy Engineering completed a sewer study to determine:

• Capacity of nearby municipal sewer mains

• Potential off-site improvements

• Optimized location of potential off-site improvements

This early analysis helped the developer understand whether the site could be served efficiently under existing city infrastructure and if not, what improvements would need to be constructed.

Earthwork & Grading Study

A conceptual earthwork study was performed to assess:

• Existing ground elevations

• Required grading to support street and lot design

• Preliminary cut-and-fill balance

• Areas requiring import or export of material

• Feasibility of maintaining positive drainage without excessive grading

This step ensured the project could be constructed economically, avoiding unexpected costs associated with major elevation changes or material hauling.

Phasing Strategy & Development Planning

At the conclusion of the study, Legacy Engineering provided guidance on potential development phasing, including discussion of variables that commonly influence phasing decisions, such as:

• Utility extension requirements

• Up-front infrastructure costs

• Market absorption and sales velocity

• Street and drainage system sequencing

• Cash-flow considerations for developers

This allowed the client to plan a feasible, financially responsible approach to construction that aligned with both city expectations and long-term project goals.
