Applying for a Miami-Dade Class VI Water Control Permit means assembling a complete, environmentally sound package for a drainage system on a contaminated or hazardous-material site. Because the county will not process an incomplete submittal and the scrutiny is high, the order in which you build the package matters. Endless Life Design runs every step of this process through our $4,500 Government Permit Processing Service. Call (305) 680-3283 before you begin so the application is built correctly from day one.

How Endless Life Design Runs the Application for You
1. Establish the Site's Environmental Profile
The first step in a Class VI application is understanding the site's environmental profile: the nature of any known contamination and the hazardous materials the operation will use or store. This profile shapes the entire application, because the drainage must be designed to address the specific environmental risk. Skipping this step leads to a design that cannot satisfy the review.
Establishing the profile draws on site history, environmental assessments, and the planned operation. It is the foundation everything else is built on. Endless Life Design begins here, clarifying the environmental conditions and risks so the drainage design and the rest of the package are grounded in the site's actual circumstances rather than assumptions.
2. Confirm Class VI Is the Correct Permit
Next, confirm that Class VI is the right permit, recognizing that a project may also implicate other classes. Class VI covers contaminated or hazardous-material sites, Class II covers discharge to a water body, and Class III covers work within a canal corridor. A sensitive site that also discharges to a canal could involve more than one class.
Filing under the wrong class, or missing a second applicable class, costs time and fees. Endless Life Design evaluates the project against all three definitions to determine which permits are required. Call (305) 680-3283 if you are unsure which classes apply to your sensitive site.
3. Design Drainage That Addresses the Risk
With the profile established, the drainage system is engineered to manage stormwater while addressing the environmental risk, so contaminants are not mobilized or spread. This is the heart of a Class VI design and is more demanding than ordinary drainage, because the county's central concern is protecting groundwater and surface water from the site's contamination or materials.
The design must reflect the specific site conditions, contamination, and hazardous-material handling, not a generic template. Endless Life Design coordinates engineers experienced with sensitive-site drainage so the system speaks directly to the risk, giving the application a sound technical foundation the county can approve.
4. Prepare the Construction Plans
The construction plans must clearly show the drainage system and how it manages stormwater on the sensitive site. A reviewer needs to see the engineered system in full, drawn to a standard that supports the calculations and certification. On a Class VI project, the plans carry the added weight of demonstrating environmental soundness.
Plans that are vague or inconsistent with the calculations are a frequent cause of returns, and on a high-scrutiny Class VI review the margin is even thinner. Endless Life Design coordinates the plan set with the drainage calculations so the documents describe one identical, defensible system, eliminating the contradictions that derail review.
5. Complete the Drainage Calculations
The drainage calculations must demonstrate that the engineered system manages the project's stormwater appropriately given the site's environmental conditions. They reflect the specific site, its soils, water table, and contamination or hazardous-material profile, and they must align precisely with the construction plans.
On a sensitive site, the calculations bear directly on the county's core concern about containment and risk, so they must be thorough and defensible. Endless Life Design works with the engineer to ensure the calculations and the plans are in lockstep and that they address the environmental conditions, since a mismatch or gap is fatal to a Class VI review.
6. Order the Signed-and-Sealed Survey
A signed-and-sealed topographic or boundary survey is required, establishing the measured reality of the site for the reviewer. The survey follows a roughly seven-day workflow: a surveyor visits the site, performs a site analysis, measures the property corners and existing improvements, processes the field data, and issues the sealed document.
Building this lead time into the schedule prevents a stall, because the county cannot evaluate the drainage without verified site conditions. Endless Life Design coordinates the survey early so it is current, sealed, and consistent with the engineered drainage design for the sensitive site.
7. Add the Aerial or Location Map
The application also requires a vertical aerial photograph or project location map, situating the project in its surrounding context so the reviewer understands the setting and the drainage relationships. This complements the precise survey with a broader view of the site and its environment.
Though easy to underestimate, a missing or unusable location aerial can hold up an otherwise complete package. Endless Life Design includes a clear, appropriate aerial or location map alongside the survey and plans, so the submittal gives the reviewer both the site detail and the surrounding context.
8. Secure the Engineer Letter of Certification
The engineer letter of certification, the county's Attachment A, is a required element in which a Florida-licensed engineer attests that the drainage design meets the applicable standards. On a Class VI project the certification carries added weight because of the environmental stakes, and the application is incomplete without it.
The certification must be specific to the sensitive site and its engineered drainage, not a generic statement. Endless Life Design ensures it is current, specific, and consistent with the plans and calculations, so it stands up to the heightened review. Call (305) 680-3283 to coordinate the certification correctly.
9. Calculate the Fee and the 7.5% Surcharge
The application fee is tied to the project's estimated cost and includes a 7.5% RER surcharge. Because the fee scales with valuation, the correct figure must be confirmed against your project's true estimated cost, and the surcharge included in the budgeted amount. An incorrect fee can itself delay intake.
Establishing an accurate estimated cost is part of filing cleanly and should be consistent with the project's real scope. Endless Life Design helps set the correct valuation and fee tier so the application is accepted without questions over the fee, keeping intake smooth on an already demanding review.
10. File a Complete Package and Respond to Comments
With every element in hand, the package is filed with Miami-Dade DERM as a single complete submittal, and after filing the county may issue comments during its review. A complete, consistent package is accepted and reviewed, while a partial one is returned, so filing complete the first time is what protects the schedule on a sensitive-site project.
Responding to the county's comments promptly, accurately, and consistently is essential to keeping the application moving. Endless Life Design files complete, having confirmed the documents agree, and then manages the county's comments on the applicant's behalf, carrying the application through to an issued permit.
11. Realistic Timeframes for a Sensitive Site
Owners want a timeline, and the honest answer is that Class VI review depends on the completeness of the package, the complexity of the contamination or hazardous-material profile, and the county's workload. Sensitive-site reviews can be more involved than routine drainage, so a complete, well-prepared submittal matters even more, and no fixed date can be guaranteed.
The practical lesson is to start early and prepare thoroughly, since the engineering and survey carry their own lead times and the review is rigorous. Endless Life Design sequences the work to keep the Class VI approval moving and sets realistic expectations rather than promising dates the county does not guarantee.
12. 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 establish the environmental profile, confirm the permit class, coordinate sensitive-site drainage engineering and calculations, order the survey, prepare the plans and aerial, secure the certification, set the correct fee, and file a complete package with Miami-Dade DERM.
From there we track the review, respond to comments, and carry the application to an issued permit, so you never have to learn the county's environmental intake process or chase a correction notice.
