Definition & Meaning of the City of Houston Impervious Cover Form
The City of Houston impervious cover form, commonly referred to as the CE1207 Calculation of Impervious Percentage, is a crucial document used to assess the percentage of a property that is covered by surfaces that do not allow water to penetrate. This includes materials such as concrete, asphalt, and certain types of roofing. The form plays a significant role in stormwater management, helping to ensure that developments comply with local regulations aimed at managing runoff and preventing flooding.
Understanding the impervious cover percentage is essential for determining whether a property requires stormwater detention facilities or qualifies for specific adjustments under Houston's drainage regulations. This form is particularly relevant for new constructions, significant remodels, and properties undergoing expansions.
How to Use the CE1207 Calculation of Impervious Percentage
To effectively use the CE1207 form, applicants must gather detailed information about their property. This includes measurements of all impervious surfaces, such as:
- Building footprints
- Driveways
- Sidewalks
- Patios
- Swimming pools
Once the data is collected, applicants can calculate the total impervious area and then determine the percentage of the property that is impervious by comparing it to the total lot area. This percentage is essential for compliance with local stormwater management policies.
How to Obtain the CE1207 Form
The CE1207 form can be obtained directly from the City of Houston's official website or through the Houston Public Works department. It is typically available in a downloadable PDF format, which can be printed and filled out manually. Additionally, applicants may find the form at local government offices or request it via email or phone from the relevant department.
How to Fill Out the CE1207 Form
Filling out the CE1207 form requires careful attention to detail. Here are the key steps:
- Property Information: Enter the address and legal description of the property.
- Applicant Information: Provide the name and contact information of the applicant.
- Area Breakdown: List all impervious surfaces along with their respective square footages.
- Total Impervious Percentage: Calculate and enter the final percentage of impervious cover based on the total area of the property.
Accuracy is vital, as any discrepancies can lead to compliance issues or delays in the approval process.
Why the CE1207 Form is Important
The CE1207 form serves several critical functions:
- Stormwater Management: It helps ensure that new developments manage runoff effectively, which is essential for preventing flooding.
- Regulatory Compliance: The form is often a requirement for obtaining construction permits, ensuring that all projects adhere to local stormwater regulations.
- Flood Mitigation: By tracking impervious surfaces, the city can better manage increased runoff and implement necessary flood control measures.
Who Typically Uses the CE1207 Form
The CE1207 form is primarily used by:
- Property developers and builders engaged in new construction projects.
- Homeowners planning significant renovations or expansions that increase impervious surfaces.
- Engineers and architects involved in site planning and design.
These users must ensure compliance with local regulations to avoid potential fines or project delays.
Key Elements of the CE1207 Form
Understanding the essential components of the CE1207 form is crucial for its successful completion. Key elements include:
- Project Details: This section requires basic information about the property and the applicant.
- Area Breakdown: A detailed list of all impervious surfaces, including their measurements.
- Total Impervious Percentage: The calculated percentage that indicates how much of the property is impervious.
Each of these elements contributes to the overall assessment of the property’s compliance with stormwater management regulations.
Examples of Using the CE1207 Form
Consider a scenario where a homeowner plans to build a new garage. The homeowner must calculate the impervious cover by measuring the garage's footprint and any additional paving required for access. If the garage adds 600 square feet of impervious surface to a property that is 2,000 square feet in total, the calculation would be:
Total Impervious Percentage = (600 / 2000) * 100 = 30%
This percentage will then be reported on the CE1207 form to determine if additional stormwater management measures are necessary.
Legal Use of the CE1207 Form
Legally, the CE1207 form is required for compliance with Houston's drainage regulations. Failure to submit an accurate form can lead to penalties, including fines or the denial of construction permits. It is essential for applicants to understand the legal implications of the information provided on the form.
