(2) Information required - all permits. The following information is required of all applicants for all permit categories, unless the department determines that specific information will not be required on individual applications. Additional information required of Category II, III, and IV permit applications is specified in this chapter. In all cases it would be prudent, prior to submittal of the application, for the applicant to inquire of the department whether the application needs additional information. The department reserves the right to request clarification or additional information during the application review process. Failure to provide the requested information within the time limits specified in the request shall result in withdrawal of the permit application.

(a) Identification and signature of property owner and applicant. The current complete names, mailing addresses, and telephone numbers of the property owner(s), the developer(s), the applicant, the transportation and legal consultants representing the applicant (if any), and the local government representative(s) responsible for processing the development's approval shall be provided as part of the application. If the property owner desires to have a representative sign the application, a notarized letter of authorization from the applicant is to be provided with the application. When the owner or applicant is a company, corporation, or other public agency, the name, address, and telephone number of the responsible officer shall be furnished. The names of all individuals signing the application and their titles shall be typed or printed directly below the signature.

If local or special trip generation rates are used, instead of the ITE rates the latest and best information shall be used and all documentation for the rate development shall be submitted with the application. For residential developments with ten or fewer units, ten trips per day per unit may be assumed. The requirement for an average weekday vehicle trip ends estimate may be waived for agricultural uses where no retail marketing is proposed.

(c) Site plan. The application shall include a plan to scale, or a schematic drawing showing critical dimensions (allowable on Category I permits only), the location of the property, and existing conditions and the character and extent of work proposed. The location of existing and proposed on-site development with respect to the existing and proposed driveway location(s) and the highway shall be shown. Minimum information on the plan shall include:

(i) Road information.

• State route number.

• County or local road name.

• Highway pavement type.

• Cross section.

• Posted speed limit.
