Sections 14-5-2-1 et seq. shall apply to all lands within the city and, with respect to planning and platting matters, it shall also apply to all lands within its extraterritorial planning and platting jurisdiction. This jurisdiction is not exclusive; in particular, in matters of flood control AMAFCA shares jurisdiction.
(A) The city is and shall remain an active participant in the National Flood Insurance Program. The city endorses the program goal of flood damage reduction through the regulation of development within flood hazard areas and the preservation of floodways. Sections 14-5-2-1 et seq. are intended to complement and supplement the Flood Hazard Ordinance set forth in §§ 14-5-1-1 et seq. of this article and shall be administered in concert therewith.
(B) All developed land within the city shall be provided with adequate drainage control, flood control, stormwater control, and erosion control facilities. The protection of life, health, and property shall be considered the primary function in the planning, design, construction and maintenance of drainage control, flood control, stormwater control, and erosion control facilities. However, other concerns, not limited to the following, shall be addressed: channel capacity, watershed characteristics, channel stability, maintenance, transitions between treatment types, multiple use goals, and appearance. The needs of the community in transportation, utility services, recreation, and open space shall be considered in planning, design, construction, and maintenance-particularly in the selection of channel treatment measures. These needs shall always be considered subsidiary to the primary functions of the drainage control, flood control, stormwater control, and erosion control facilities.
(C) The design, construction and maintenance of dams, levees and diversions that fall within the jurisdiction of the State Engineer shall meet or exceed standards established by the State Engineer.
(D) The design, construction and maintenance of flood control facilities shall be coordinated with AMAFCA or other public agencies as appropriate.
(E) All facilities receiving water from public facilities and rights- of-way shall be constructed within dedicated rights-of-way or recorded drainage easements granted to and accepted by the proper public authority or a private entity with an agreement for operations and maintenance.
(F) All facilities which receive only runoff from private property shall be constructed on private property unless otherwise authorized by the City Engineer. The use of individual on-lot ponding shall be governed by the standards established by the City Engineer in the Development Process Manual.
(G) Wherever flood control, drainage control, stormwater control, or erosion control improvements are necessary within dedicated public open space, such improvements shall be designed and constructed in a manner reasonably consistent with the natural surroundings. All construction and maintenance activities in dedicated open space shall be performed so as to minimize the disruption and destruction of vegetation and adjacent land forms. Where such disturbance or destruction is unavoidable, revegetation shall be performed at the earliest practical time by those responsible for such disturbance and/or destruction.
(H) All new development projects shall, where practicable, manage the runoff from precipitation from 90th Percentile Storm Events, utilizing appropriate techniques such as the following, to detain, retain and/or dispose of said runoff: infiltration into soil, extended filtration procedures, water harvesting, evapotranspiration, or other techniques appropriate under the circumstances, and any combination of these practices. Generally, it shall not be deemed "practicable", in the context above, in site development cases that include but are not limited to: (i) cases of conflicts with water rights appropriations requirements, (ii) cases where post-development drainage planning that does not and/or cannot practically connect to the River, and (iii) cases where appropriate public or private drainage facilities are available 'offsite' and will be be used in a manner consistent with the goals of this Ordinance to manage the Project runoff from precipitation from 90th Percentile Storm Events.
(I) Where practicable, Stormwater Control Measures shall be designed to manage first flush runoff and control runoff generated by contributing area impervious surfaces.
(J) The City Engineer is responsible for establishing criteria, procedures and standards for design and construction of flood control, drainage control, stormwater control, and erosion control improvements within the city. The city standards for design and construction are published in the Development Process Manual (DPM) and the Standard Specifications for Public Works Construction (latest versions). The City Engineer shall provide for variance from normal criteria and standards when appropriate. When a variance is required or requested, the City Engineer shall document the justification for his/her decision and retain as public records such actions and justifications. Appeal of the City Engineer's variance decisions is as provided in § 14-5-2-15. The City Engineer is also the designated flood control official for the city in accordance with the requirements of the Federal Insurance Administration.
(K) The introduction of groundwater cleanup flow to either natural or constructed storm drainage and flood control facilities shall be prohibited except as herein provided.
§ 14-5-2-7 SURFACE USE OF STREETS FOR DRAINAGE AND FLOOD CONTROL PURPOSES.
(A) The surface of streets may be used for drainage and flood control purposes, to the extent such use does not interfere with the safe transportation of people and vehicles.
(B) The 100-year design storm runoff shall not exceed a depth of 0.87 feet at any point within the street right-of-way, or 0.2 feet above top of curb, in any street nor enter private property from a street, except in recorded drainage or flood control easements, rights-of-way, or historic channels and watercourses where easements or rights-of-way cannot be obtained.
(C) The 10-year design storm runoff shall not exceed a depth of 0.5 feet in any arterial street and shall flow such that one driving lane in each direction is free of flowing or standing water. The 10-year design storm runoff shall not exceed a depth of 0.5 feet in any collector street. Arterial and collector streets that are in the state highway system may require more stringent drainage criteria.
(D) The product of depth times velocity shall not exceed 6.5 at any location in any street in the event of a 10-year design storm (with velocity calculated as the average velocity measured in feet per second and depth measured at the gutter flow line in feet).
(E) The discharge of nuisance waters to public streets shall be discouraged. Arterial and collector streets shall be protected from damages to the pavement surface and from the safety hazards created by surface flow of nuisance waters across them.
(F) All developed land within the city shall be served by at least one access that shall be an all-weather facility during a 100-year design storm, with all channel-crossing structures beneath the road-way being able to pass a 100-year design storm runoff event.
(A) Channel crossing structures shall be provided on all arterial and collector streets to safely pass the 100-year design storm runoff from major arroyos assuming a fully developed watershed.
(B) Streets other than arterial, collector and sole access may cross major arroyos and other water-courses by means of a "dip section" or "overflow section" provided depth times velocity (with velocity calculated as the average velocity measured in feet per second and depth measured in feet at the upstream edge of the roadway including sidewalk) does not exceed 6.5 for that portion of the 10-year storm runoff crossing on the street.
(C) Where feasible, temporary crossings shall be designed so they may be incorporated into the future permanent crossing structure and so that they meet street design standards established by the Traffic Engineer.
(D) Crossings of major arroyos by arterial and collector streets shall be at public expense. Crossings of arroyos by streets other than arterials and collectors shall be constructed at developer expense and shall meet street design standards established by the Traffic Engineer.
(E) Temporary crossings required for access, including those on arterials and collectors, shall be constructed at developer expense.
(A) The city may participate in the construction of permanent flood control facilities to the extent that public benefits are derived from such construction and consistent with Capital Improvements Program (CIP) priorities. Reimbursement for private funding of such projects may also be available under these conditions.
(B) The city may participate in the costs of channel crossing structures on arterial and collector streets which are required for sole access to a development. The developer's share shall not exceed the cost required to meet the minimum street width standards established by the Traffic Engineer.
(C) The city shall not participate in the funding of flood control facilities whose sole purpose is the reclamation of undeveloped land located within a flood hazard area for private development purposes.
(D) All drainage control, flood control, stormwater control, and erosion control facilities which directly result from a proposed land use change are the responsibility of the developer. Developer financed facilities include all those within the boundaries of the development, those required for development adjacent to a major arroyo or within a flood hazard area and, all temporary and permanent off-site drainage facilities. Master planned facilities shall be the responsibility of the city and in some instances AMAFCA. However, if such facilities are not programmed and funded at the time of development, the developer shall construct the master planned facilities or provide for temporary facilities, constructed to City Engineer standards within a temporary or permanent drainage easement until such time that the city or AMAFCA constructed facilities are in place. If the construction of such facilities is a condition of plat approval or building permit issuance, then financial guarantees of such construction satisfactory to the City Engineer shall also be provided as a prerequisite. The City Engineer shall coordinate the construction and location of temporary facilities with AMAFCA and other city departments. If the ultimate on-site drainage control, flood control, stormwater control, or erosion control facilities require permanent rights-of-way or easements, such rights-of-way or easements shall be dedicated at the time of platting or building permit issuance, whichever occurs first.
(E) Except as allowed by AMAFCA Resolution 81-8 and amendments thereto, the dedication of land for public purposes does not relieve a developer of responsibilities for the construction of drainage control, flood control, stormwater control, and erosion control facilities that would otherwise be necessary. The dedication of rights-of-way or easements for drainage control, flood control, stormwater control, or erosion control facilities does not relieve a developer of responsibilities that would otherwise exist for the construction of other public infrastructure.
§ 14-5-2-10 MULTIPLE USE RIGHTS-OF-WAY AND EASEMENTS.
(A) Multiple use is encouraged for drainage rights-of-way and drainage easements including, but not limited to, utility corridors, recreation trails, and parks. Where multiple use is planned by the city, another public agency, or a public utility, the city may require that dedication statements include language which permits said specified multiple uses in addition to the primary drainage function, flood control, stormwater control, or erosion control. However, land required to be dedicated for drainage related rights-of-way shall be limited to those land areas necessary for drainage control, flood control, stormwater control, and erosion control and necessary appurtenances.
(B) Certain drainage rights-of-way in Sector Development Plans may be credited for Zoning Code detached open space, except for any area which is exclusively used for the drainage control, flood control, stormwater control, or erosion control function.
§ 14-5-2-11 STORMWATER CONTROL PERMITTING FOR EROSION AND SEDIMENT CONTROL, INSPECTION, AND MAINTENANCE RESPONSIBILITY.
(A) A current Stormwater Control Permit for Erosion and Sediment Control is required for all construction, demolition clearing, and grading operations within the City of Albuquerque that disturbs the soil on one acre or more of land.
(1) The Stormwater Control Permit for Erosion and Sediment Control holder must be either the owner of the property or an authorized agent of the owner in order for the permit to legally cover the activities occurring at the site. If the permit holder is other than the owner, evidence of delegation of authority acceptable to the city shall be provided prior to issuance of a permit by the city.
(2) Upon approval of plans and conditions by the City Engineer, a Stormwater Control Permit for Erosion and Sediment Control will be issued as set forth in the Development Process Manual. The permit shall specify the time period covered by the permit, as set by the City Engineer in the manner established in the Development Process Manual, but such time period may not extend beyond the acceptance of the Notice of Termination unless otherwise specifically identified in the Stormwater Control Permit. An owner's or his/her agent's failure to properly maintain or extend a Stormwater Control Permit for Erosion and Sediment Control shall subject that owner to the penalty provisions of this ordinance.
(1) Self-inspections by permittee. At a minimum a routine compliance self- inspection is required to review onsite and immediately adjacent property vegetation, erosion and sediment control measures, and other protective measures identified in the Erosion and Sediment Control Plan and the associated Stormwater Permit for Erosion and Sediment Control, if any. Until the site construction has been completed and the Stormwater Control Permit for Erosion and Sediment Control closed out and the Notice of Termination approved under the General Construction Permit, the owner or his/her agent shall make a thorough inspection of the stormwater management system as established by the Erosion and Sediment Control Plan. These inspections' frequency shall be based on site conditions and project circumstances as noted in the site's Erosion and Sediment Control Plan. Regardless of the planned frequency, inspections shall occur after each precipitation event of ¼ inch or greater. Reports of these inspections shall be kept by the person or entity authorized to direct the construction activities on the site and shall be conducted during progress of the work, during work suspensions, and until final acceptance of site stabilization by the city. An owner's or his/her agent's failure to properly maintain records as required by Erosion and Sediment Control Plan shall subject that owner to the penalty provisions of this ordinance.
(2) City Compliance Inspections. The city will require compliance inspections in accordance with the permitee's Erosion and Sediment Control Plan, conducting annual compliance inspections of all construction projects cumulatively disturbing one acre or more. Site inspections will be followed by any necessary compliance or enforcement action to ensure corrective maintenance has occurred. All projects will be inspected at completion for confirmation of stabilization prior to the submittal of the Notice of Termination under the General Construction Permit.
(a) Erosion and Sediment Control Compliance. If the city finds that erosion and sediment controls are not preventing accelerated erosion and removing sediment and waste prior to the drainage leaving the construction site, the city may direct the owner or his/her agent by written order to implement additional erosion control measures to prevent said soil erosion and sediment and waste migration. If immediate additional erosion and sediment control or repair is necessary, the owner or his/her agent shall be verbally notified with a follow-up written confirmation occurring later. It shall be the duty of the owner or his/her agent to immediately take all necessary steps to prevent such migration of sediment and waste off the premises or from entering receiving waters. Delivery of an order by the city to the owner or his/her agent shall be deemed to be notice thereof, and binding upon the owner. An owner's or his/her agent's failure to substantially comply with the order shall subject that owner to the penalty provisions of this ordinance.
(b) Maintenance of Temporary Control Measures. The property owner or the owner's agent carrying out the soil erosion and sediment control measures shall maintain all temporary control measures, retaining walls, structures, plantings, and other protective devices. Should the applicant, or any other subsequent property owners fail to maintain the temporary control facilities, retaining walls, structures, plantings, and other protective devices, the city reserves the authority to enter affected property, provide needed maintenance, and to charge the owner for the work performed by the city or its contractors and to place a lien on the property to cover the costs of said actions. Such municipal lien shall be a statutory lien against the real property. This provision is in addition to the city's ability to assess penalties or pursue any other remedies as necessary to effectuate the purpose of this ordinance.
1. The maintenance of temporary facilities constructed at private expense on public property is the responsibility of the owner or owner's agent until permanent facilities are in place.
2. The developer shall be responsible for maintaining or replacing temporary crossing structures for a period of six years or until a permanent structure is built, whichever comes first. The city shall maintain temporary crossings which are designed and built such that they may be directly incorporated into the ultimate facilities.
(3) The city will utilize sanctions and penalties to enforce upon violations of permit requirements. Progressive enforcement escalation procedures will be used and strictly enforced for recalcitrant or repeat offenders.
(1) Except as otherwise noted herein, all Public Stormwater Facilities shall be maintained by the city or other public body. The maintenance of multiple use facilities to which the general public is denied access shall be the responsibility of the owners and shall be performed to City Engineer standards. The City Engineer may allow private maintenance within public right-of-way or easement provided that adequate guarantees and indemnifications are supplied.
(2) Private Stormwater Facilities shall be maintained by the facilities' owner to standards established by the City Engineer and published in the Development Process Manual. Periodic inspection and certifications of facilities are hereby required and shall be reported to the City Engineer on forms established by the city. Inspections and Certifications by a New Mexico Professional Engineer shall occur not less frequently than once every 3 years from the date the Notice of Termination is signed. Ongoing Stormwater Control Permit obligations may be required as to Stormwater Control Measures.
(3) Maintenance and operation necessitated by the discharge of any groundwater cleanup flow to any public storm drainage, flood control, stormwater control, or erosion facility shall be the responsibility of the originator of such a discharge. Groundwater cleanup flow discharges shall only be allowed by special agreement.

(4) Erosion and Sediment Control Plan. Erosion and Sediment Control plans address all phases of each project from initial grading through and including final occupancy and periodic post construction maintenance. Phased projects require special attention. All construction projects, both public and private, within the jurisdiction of §§ 14-5-2-1 et seq. unless specifically excluded require an approved Erosion and Sediment Control plan prior to start of construction.
(J) The Albuquerque 100-year design storm is the 100-year 6-hour storm as defined by the National Oceanic Atmospheric Administration (NOAA) and by the storm distributions for time and areas as developed by the City Engineer. The 100-year storm has a 1% probability of occurring in any year. Watersheds with times of concentration greater than six hours will require the use of the 100-year 24-hour storm volumes and distributions. Detention basins within which at least 90% of the design storage volume is not evacuated within 6 hours measured from the time the peak storage volume is reached, shall use a 24-hour or longer storm volume and distribution. Design circumstances may require larger or smaller storm volumes. The sources for the rainfall data are current NOAA publications and the City Engineer. When the need for other design storms is apparent, the City Engineer will provide requirements concerning appropriate storms, frequencies and durations.
(K) The City Engineer shall, within 30 calendar days after the submission to him/her of a request in writing for an approval under the Drainage Ordinance, approve or deny the request and provide a copy of his/her decision to the applicant. If the request is denied, the reasons for such denial shall be stated in writing. Appeal of such decisions is as provided in § 14-5-2-15.
(L) Discharge of any groundwater cleanup flows to the city's storm drainage and flood control system shall not normally be permitted, however, when such discharge of groundwater cleanup flow is by special agreement permitted, the entity responsible for such groundwater cleanup flow discharge shall also be responsible for all costs of installing, operating and removing the means of such discharges and shall provide public liability protection as required. The discharger of such groundwater cleanup flows shall also be responsible for payment of such permit fees, user fees, and effluent sampling fees according to an agreement with the city. All discharges to public storm drainage and flood control facilities shall comply with adopted local and applicable state and federal water quality requirements.
