The Construction Official shall collect a cash bond in all cases where an application requests a permit for renovation, alteration, repair or new construction, hereinafter called "improvement." The cash bond shall be in the amount of $500 when the cost of the improvement, in the estimation of the Construction Official, shall equal or exceed $5,000. The cash bond shall be in the amount of $200 when the cost of the improvement, in the estimation of the Construction Official, shall be less than $5,000. The applicant shall, during the course of such construction, regularly clean up all debris and dirt from the streets, sidewalks and curbing abutting the property for which the construction permit was issued. Upon the completion of such renovation, alteration, repair or new construction, and the Construction Official and the appropriate subcode officials having inspected same and found it to be satisfactory, and, if applicable, the Borough Engineer having also determined that any and all damages to the streets, sidewalks and curbing abutting the property for which the permit was issued have been repaired and all debris and dirt deposited thereon has been properly cleaned, the cash bond, without interest, shall be returned to the applicant. Patching of damaged curbs will not be accepted. Removal and replacement of damaged curbs shall be required. No certificate of occupancy shall be issued until the Borough Engineer has certified to the Construction Official, in writing, that the curb complies with the requirements of the curb specifications as set forth in Chapter 192, Streets and Sidewalks, § 192-24. At the time of the return of the cash bond, the Borough may charge the applicant a curb inspection fee, not to exceed $75 for each inspection. All repairs to damaged curbs shall be at the applicant's expense.
