Sediment shall be removed from sediment traps or sediment ponds whenever their design capacity has been reduced by 50%.
B. 
For land development or redevelopment activities as defined in § 226-6 of this chapter and meeting Condition A, B or C in § 226-8B of this chapter, the applicant shall have a qualified professional conduct site inspections and document the effectiveness of all erosion and sediment control practices every seven days and within 24 hours of any storm event producing 0.5 inch of precipitation or more. Inspection reports shall be maintained in a site logbook.

The applicant or developer or their representative shall be on site at all times when construction or grading activity takes place and shall inspect and document the effectiveness of all erosion and sediment control practices.
Prior to the issuance of any approval that has a stormwater management facility as one of the requirements, the applicant or developer must execute a maintenance easement agreement that shall be binding on all subsequent landowners served by the stormwater management facility. The easement shall provide for access to the facility at reasonable times for periodic inspection by the City to ensure that the facility is maintained in proper working condition to meet design standards and any other provisions established by this chapter. The easement shall be recorded by the grantor in the office of the City Clerk after approval by the Corporation Counsel.
The owner or operator of permanent stormwater management practices installed in accordance with this chapter shall ensure they are operated and maintained to achieve the goals of this chapter. Proper operation and maintenance also includes, as a minimum, the following:

A preventive/corrective maintenance program for all critical facilities and systems of treatment and control (or related appurtenances) which are installed or used by the owner or operator to achieve the goals of this chapter.
B. 
Written procedures for operation and maintenance and training new maintenance personnel.

Discharges from the SWMPs shall not exceed design criteria or cause or contribute to water quality standard violations in accordance with § 226-11C of this chapter.
The City shall approve a formal maintenance agreement for stormwater management facilities binding on all subsequent landowners and recorded in the office of the City Clerk as a deed restriction on the property prior to final plan approval. The maintenance agreement shall be consistent with the terms and conditions of Schedule B found at the end of this chapter entitled "Sample Stormwater Control Facility Maintenance Agreement." The City, in lieu of a maintenance agreement, at its sole discretion, may accept dedication of any existing or future stormwater management facility, provided such facility meets all the requirements of this chapter and includes adequate and perpetual access and sufficient area, by easement or otherwise, for inspection and regular maintenance.
