Residential Infill Grading Waiver Affidavit – Dallas, TX

The Residential Infill Grading Waiver Affidavit is a two-page City of Dallas affidavit in which the owner or applicant (authorized agent) of new construction swears that lot grading will not harm drainage, in place of an engineer-sealed grading plan.

The affiant states that the property is not in the flood plain, that no filling has occurred to remove the flood plain designation and that no flood plain alteration permit has been issued. The affiant also confirms an understanding of Chapter 52, Administrative Procedures for the Construction Codes, Section 607.1 (Erosion and Siltation Control) and Section 608.1 (Site Drainage), and of Dallas Development Code Article VIII, Section 51A 8.611 (e), which prohibits Lot-to-Lot drainage, and states that the City of Dallas grading procedures were reviewed.

You check one of three statements:

• A. replacing an existing structure with a new structure of similar slab square footage;
• B. new structure on a vacant lot (a site never built on);
• C. replacing an existing structure with a new structure of greater square footage.

Page 2 adds the affiant's commitments: to repair an as-built condition that the Building Official finds causes adverse impact on abutting lots, and to follow an Engineered Plan if the City requests one. The form is headed Planning & Development Department, 320 E Jefferson Blvd, Dallas TX 75203, and carries the date 4/21/2025.

The owner of new construction in Dallas, or the applicant acting as authorized agent, signs this affidavit when providing it in lieu of a grading plan sealed by a professional engineer.

The form is available only if all of the following are true, because the affiant swears to them:

• the property is not in the flood plain;
• no filling has occurred to remove the flood plain designation;
• no flood plain alteration permit has been issued.

You then check one situation only: A (replacement structure of similar slab square footage, same area, same or less square footage, same pad elevation), B (new structure on a vacant lot never built on) or C (replacement structure of greater square footage). Under each, the pad elevation may not exceed one (1) foot above the existing lot grade.

The form has fields for a title and a business entity, so a person signing for a company or as an agent states that capacity. If the property does not meet these statements, the form is not the right document; the City may also request an engineered grading and drainage plan if adverse drainage conditions are noted.

The form prints no due date. The triggering event is that you are offering the affidavit in lieu of a grading plan sealed by a professional engineer for new construction on a Dallas property, so it is completed when that plan would otherwise be provided.

Timing also matters after signing. If an Engineered Plan is later obtained, the affiant agrees to follow it and any amendments within one year of the final building inspection, unless the purchaser (or a subsequent purchaser) has altered the as-built grade or drainage.

The form names no submission channel. It prints the header Planning & Development Department, 320 E Jefferson Blvd, Dallas TX 75203, and the telephone number (214) 948-4480, which are the contact details to use to confirm where and how the signed affidavit is delivered.

Before delivery, complete the notary block on page 2: the form ends with "Subscribed and sworn to before me" and a line for the notary public and state. Signature, printed name, title, business entity, mailing address, telephone and e-mail are all part of the signature block.
