Applying for a Miami-Dade Class II Water Control Permit is less about filling out a form and more about assembling a complete, internally consistent engineering package that the Department of Regulatory and Economic Resources will accept on the first pass. Because the county will not process an incomplete submittal, the order in which you build the package matters. This guide walks the real sequence, and Endless Life Design runs every step of it for owners and contractors through our $4,500 Government Permit Processing Service. Call (305) 680-3283 before you begin so the package is built correctly from day one.

How Endless Life Design Runs the Application for You
1. Start With a Drainage Design That Reaches a Water Body
Every Class II application begins with the civil engineering. A Florida-licensed engineer designs how stormwater will move across your site and where it will ultimately discharge, and it is that discharge to a water body that brings the project under Class II review in the first place. Before any paperwork, the drainage concept must be settled, because every other document in the package is built to support and prove that design.
Owners who try to apply before the drainage design is finalized inevitably circle back and redo work. The plans, calculations, survey, and certification all reference the same engineered system, so a change to the design ripples through the entire package. Locking the drainage approach first, with the discharge point clearly defined, is the foundation that keeps the rest of the application from unraveling later.
2. Confirm Class II Is the Correct Permit
Before assembling documents, confirm that Class II is actually the permit your project needs. Class II covers drainage systems that overflow or discharge to a water body, while construction within a county canal right-of-way falls under Class III, and drainage on contaminated or hazardous-materials sites falls under Class VI. Filing under the wrong class wastes time and fees and forces a restart.
This determination is not always obvious from a site plan, and a project can even touch more than one class. Endless Life Design evaluates the design against all three definitions so the application is filed correctly the first time. If you are unsure which water control permit applies, call (305) 680-3283 before you file anything.
3. Assemble the Construction Plans
The construction plans are the backbone of the submittal. They must clearly show the drainage system, the grading, the control structures, and the discharge point, drawn to a standard a county reviewer can evaluate. These are not conceptual sketches; they are the engineered drawings that the rest of the package certifies and supports, and they must reflect the final design rather than an early iteration.
Plans that are vague, outdated, or inconsistent with the calculations are a frequent cause of returns. The reviewer needs to trace the stormwater path from collection to discharge and confirm it matches the engineering. Endless Life Design coordinates the plan set with the drainage calculations and survey so the three documents describe one identical system, eliminating the contradictions that send packages back unreviewed.
4. Prepare the Drainage Calculations
One set of drainage calculations must accompany the plans, demonstrating that the engineered system manages the project's stormwater and discharges safely to the receiving water body. These calculations reflect your specific site, including its area, soils, water table, and discharge conditions, and they are the technical proof behind the design the plans illustrate.
Because South Florida sits on a high water table and flat terrain, the calculations carry real weight; a generic approach will not satisfy a reviewer. The numbers must align precisely with what the plans show. Endless Life Design works with your engineer to ensure the calculations and the drawings are in lockstep, since a mismatch between them is among the most common and avoidable reasons a Class II package is rejected.
5. Order the Signed-and-Sealed Survey
Class II requires one copy of a signed-and-sealed topographic or boundary survey establishing the measured reality of the property. This document gives reviewers the verified existing conditions they need to evaluate the proposed drainage, and it must be current rather than a years-old survey pulled from a drawer.
Producing the survey follows a roughly seven-day workflow: a licensed surveyor visits the site, performs a site analysis, takes physical measurements of the property corners and existing improvements, processes the field data, and then issues a signed-and-sealed document. Building this lead time into the schedule matters, because a stale or missing survey halts the review. Endless Life Design coordinates the surveyor so the document is current, sealed, and consistent with the engineered plans.
6. Add the Aerial, Location Map, and Engineer Certification
Two more pieces complete the technical package: a vertical aerial photograph or project location map, and the engineer letter of certification. The aerial or location map situates the project in its surrounding drainage context so the reviewer understands where the discharge goes, while the engineer's certification formally attests that the system meets the required standards.
These items are easy to underestimate, yet a package missing the certification or lacking a usable location aerial will not be processed. The certification in particular must speak to the specific standards the county expects for the receiving water. Endless Life Design assembles both alongside the plans, calculations, and survey so the submittal is whole when it reaches the counter.
7. Calculate the Fee and File a Complete Package
The final step is the application fee, which is tied to the project's estimated cost and includes a 7.5% RER surcharge. Because the fee scales with construction valuation, the correct figure must be confirmed against your project's true estimated cost rather than guessed, since an incorrect fee can itself delay intake.
With the fee set and every document in hand, the package is filed as a single complete submittal. This is the entire point of the sequence: a package that is complete and internally consistent on day one avoids the return-and-resubmit cycles that stretch timelines. Endless Life Design files complete, then tracks the review to issuance. Browse our other South Florida permit guides for related topics.
8. How Endless Life Design Runs the Application for You
Through our $4,500 Government Permit Processing Service, we manage this entire sequence on your behalf. We confirm the permit class, coordinate the engineered drainage design and calculations, order and align the signed-and-sealed survey, prepare the plans and location aerial, secure the engineer certification, set the correct fee tier, and file a complete package with Miami-Dade DERM.
From there, we track the review, respond to every comment, and carry the application through to an issued permit, so you never have to learn the county's intake process or chase a correction notice. If you are planning a project with a drainage outfall anywhere in Miami-Dade, call Endless Life Design at (305) 680-3283 and we will run the Class II application end to end.
9. Realistic Timeframes and What Affects Them
Owners always want to know how long a Class II review takes, and the honest answer is that it depends. Review timeframes vary with the completeness of the package, the complexity of the drainage design, and the county's current workload, so any fixed promise is unreliable. What is consistent is that a complete, internally consistent submittal moves faster than one that bounces back for missing or conflicting documents.
The single biggest factor within your control is completeness. A package that arrives whole and consistent avoids the return cycles that add weeks, while a partial filing resets the clock with each resubmittal. Endless Life Design files complete precisely to keep your timeline predictable, and we set realistic expectations rather than promising dates the county does not guarantee.
10. Coordinating Class II With Your Construction Schedule
A Class II permit should be started early and run in parallel with your other approvals rather than treated as a last step before construction. The survey and engineering both carry lead time, and the county review runs on its own schedule, so beginning late can stall a project that is otherwise ready to build. Sequencing these tasks from the outset keeps the drainage approval from becoming the critical path.
Because the environmental and building tracks must align, coordinating them is real project-management work. Endless Life Design files the Class II permit alongside your building approvals and manages the lead times so the pieces finish together. Call (305) 680-3283 early so your drainage permit keeps pace with your build.
File a Class II Package That Gets Accepted the First Time
A Class II permit is won at intake, by submitting a complete and consistent package rather than a partial one that bounces. Endless Life Design builds and files that package across Miami-Dade so your drainage approval keeps pace with your build instead of holding it back. Call (305) 680-3283 to put our permit team on your Class II application today.
