Site Utility Plans Service

Site Utility Plans Services For Developers

Q: Do you coordinate water, sewer, and gas utilities together in one plan?

Yes. The site utility plans service coordinates water, sanitary sewer, septic, fire protection, gas, electrical, and communication utilities into one plan, checking every crossing and separation requirement between them.

Q: Can you design a septic system for a rural property without municipal sewer?

Yes. Septic system design and engineering is provided, sizing the drain field to the site's soil percolation data and coordinating setbacks against wells, property lines, and water bodies per local health department regulations.

Q: Do you provide traffic impact studies for commercial development permitting?

Yes. Traffic impact study services are provided including trip generation, signal warrant analysis, and queue analysis using Institute of Transportation Engineers methodology.

Q: Can you handle wetland delineation and floodplain analysis on the same site?

Yes. Wetland delineation mapping and FEMA floodplain analysis are coordinated together where a site includes both jurisdictional waters and a mapped flood hazard area, including CLOMR or LOMR submittal packages where warranted.

CAD Drafter’s site utility plans service coordinates water, sanitary sewer, septic, fire protection, and gas line routing into a single utility plan that clears every crossing, every minimum separation, and every utility company’s own standard before it ever reaches a trench.

From a single water and sewer service connection on an infill lot to a full underground utility mapping and design package for a commercial development, our civil drafting team works from your site plan and the serving utility’s requirements to produce a coordinated utility plan your engineer of record can review, and your permitting authority can approve.

The Scope Of Our Civil Utility Design Services

CAD Drafter drafts the utility plan; we don’t own the water main your site ties into or the gas company’s easement running through it. Developers, builders, and civil engineers send us a site layout and a set of utility company standards; we return a coordinated plan showing where every pipe, service, and line actually runs, and how deep.

Why Developers Outsource Utility Plan Coordination

Every utility provider on a site (water, sewer, gas, electrical, and communications) publishes its own separation, depth, and material standard, and none of them are written with the other four in mind. Coordinating all of them into one buildable trench section is exactly the work outsourced civil utility design services exist to absorb.

Our Site Utility Plans Service

A utility plan is only as good as its weakest crossing. Here’s how we approach the systems that make up a complete site utility package.

Water and Sewer Infrastructure Design

Water distribution layout, sanitary sewer collection routing, and the profile sheets showing pipe slope, manhole invert, and service lateral depth for every connection on the site.

Septic System Design & Engineering

On-site wastewater treatment layout sized to soil percolation data and projected flow, with primary and reserve drain field placement coordinated against setbacks from wells, property lines, and water bodies.

Commercial Gas Line Coordination Plans

Gas utility plan drafting and coordination with the serving utility’s meter set, service line routing, and required clearance from other underground utilities and structures.

Underground Utility Mapping & Design

Existing utility mapping pulled from record drawings and utility locates, cross-referenced against every proposed line so a new trench doesn’t land on top of an existing one.

Municipal Water Main Extension Drafting

Main extension alignment, valve and fitting layout, and connection detail to the existing municipal system, sized to meet both domestic demand and fire flow requirements.

Fire Water Line & Hydrant Layout

Private fire service main sizing, hydrant spacing, and fire department connection placement coordinated with the site’s fire flow requirement and the local fire marshal’s access standard.

Water and Sewer Infrastructure Design Without Slowing Down Your Permit Timeline

Water and sewer infrastructure design and septic system design are the two scopes we take on most, alongside gas line coordination for commercial sites where the serving utility’s standard changes the layout late in design.

Standard-Referenced Design

Every Utility Line Checked Against The Standard That Governs It

A water main, a septic drain field, and a gas service line each answer to a different rulebook, and a plan that mixes up which one applies usually stalls at review. We check every line against the standard that actually governs it.

AWWA Standards

American Water Works Association design and material standards referenced for water distribution main sizing, valve spacing, and fire hydrant placement.

Ten States Standards

Recommended Standards for Water Works and Wastewater Facilities, referenced across many states for minimum separation, pipe material, and sanitary sewer design criteria.

Local Health Department OSSF Regulations

On-site sewage facility regulations governing septic system sizing, drain field setbacks, and soil percolation requirements specific to the project’s county.

NFPA 24

Standard for the installation of private fire service mains and their appurtenances, referenced on hydrant layout and fire water line sizing.

NFPA 54 (National Fuel Gas Code)

Installation and clearance requirements referenced when coordinating gas utility service line routing with other site utilities.

ITE Trip Generation Manual

Institute of Transportation Engineers trip generation rates used as the basis for traffic impact study calculations on a proposed development.

USACE Wetland Delineation Manual

U.S. Army Corps of Engineers methodology referenced for wetland delineation mapping and Section 404 permitting coordination where a site includes jurisdictional waters.

Deliverable Types

Our Process

How CAD Drafter Delivers Site Utility Plans

Our drafting workflow exists to catch every utility conflict on paper, before a backhoe finds it in the field. Here’s the 4-step process our civil drafting team follows:

Utility Standards & Site Data Review

We review your site plan, existing utility records, and each serving utility’s design standard, confirming separation and depth requirements before drafting starts.

Package Quote & Timeline

You receive a scoped price and a release date broken down by utility system, profile sheet, and any traffic or environmental coordination needed.

Drafting, Coordination & Internal QC

Our team drafts the utility layout and cross-checks every crossing and separation, then passes the plan through an internal conflict review before it reaches your desk.

Release & Revision Rounds

You receive editable plan files, with revision rounds included per your project’s drafting agreement.

Benefits Of Outsourcing To The Team

Why Firms Outsource Site Utility Plan Drafting

Keeping a designer on staff who’s fluent in five different utility companies’ standards at once is a narrow hire against a permitting pipeline that rarely needs the same combination twice. CAD Drafter’s outsourced civil utility design services let developers and builders flex drafting capacity without carrying that specialty as fixed overhead.

Lower Drafting Overhead: A per-package rate instead of a salaried utility designer on staff.

Faster Plan Release: A dedicated utility drafting team means your site utility plans aren’t queued behind someone else’s deadline. Standard packages release in 24-48 hours.

Built-In QC Review: Every plan passes an internal utility conflict and separation check before it reaches your desk for approval.

Client Feedback On Our Site Utility Plans Service

★ ★ ★ ★ ★
Water and sewer profile sheets caught a gas line conflict before we ever broke ground, which would have been an expensive fix mid-construction.

Septic layout was sized correctly against our soil report the first time, so the health department permit cleared without a single revision.

Grant PalaciosRural Homebuilder

Traffic impact study numbers matched the county’s own trip generation expectations closely enough that the signal warrant discussion took a fraction of the usual time.
