Plan set details Muir Village Phase 1 site, utilities, grading and stormwater design in Hyde Park

A set of civil engineering drawings dated September 2025 for Muir Village Phase 1 in Hyde Park, Utah, describes the proposed site layout, infrastructure, and contractor requirements for the development. The plan set, produced for Hyde Park Land Development LLC by Alliance Consulting Engineers, covers an index sheet, existing/demolition plans, a masterplan, site layout and details, three utility plan sheets, grading plans and drainage calculations.

The documents list the site as approximately 5.35 acres with 5.035 acres of development area. The plan set shows 59 total units: 47 residential units and 12 commercial units. The sheets include a buildings area of 1.677 acres (33.31% of the development), driveway and parking of 1.376 acres (27.33%), and landscape/common area of 1.982 acres (39.36%). Parking calculations state 169 stalls are required and 194 stalls are provided. The drawings indicate the creation of a homeowners association to control common open space and utility billing.

Utility plans (PG1–PG3) depict proposed 8" water mains, proposed 8" sewer mains and 4" sewer laterals, manholes with invert elevations and rim elevations, tees and fittings, and connections to existing water and sewer infrastructure. Notes call for air-release valves at crests, thrust blocks at direction changes, pressure testing and chlorination of water system components before roadway completion, and coordination with the City of Hyde Park for utility inspections and live taps. Specific pipe lengths, slopes and stationing are shown on the utility sheets.

The drainage plan includes detention/retention calculations and pond outlet details sized for 10-, 25-, and 100-year, 24-hour storms. The sheets provide computed runoff volumes, required storage and outlet box details, orifice and outlet pipe sizes, and a pond cross-section. Grading plans show finish floor elevations, contours, and proposed grading with typical cross-sections and finish grade callouts.

Site detail sheets provide pavement and sidewalk sections, curb and gutter types (APWA Type A and ribbon curb), ADA ramp and truncated dome instructions, dumpster pad details, retaining wall notes, and typical driveway and parking stall dimensions. General notes instruct contractors to comply with project specifications, APWA and City of Hyde Park standards, to field-verify dimensions, protect adjacent properties, locate all existing utilities (including fiber), and maintain erosion control until final acceptance.

The plan set is primarily a technical construction document and does not record a public hearing, council or planning commission meeting, nor does it include spoken public comment or formal votes. Where the drawings refer to coordination with city or county agencies, the plan set does not specify approvals, permit numbers or dates of review or permit issuance.
