A water quality impact assessment 763 shall also be required for any proposed land disturbance or development on contiguous steep slopes greater than or 764 equal to fifteen percent (15%) located adjacent to the landward boundary of the RPA buffer. A water quality impact 765 assessment may also be required for any proposed land disturbance or development in an RMA as regarded 766 appropriate by the County ManagerDirector due to the presence of wetlands, potential for harmful discharge of 767 contaminants from the property, or due to the unique site characteristics or intensity of the proposed use or 768 development and its potential impact on water quality. 769 770

At a minimum, aThe water quality impact assessment shall demonstrate that best management practices, 771 including but not limited to enhanced RPA buffer vegetation and/or onsite stormwater BMPsmanagement facilities 772 will retard runoff, prevent erosion, and result in pollutant reduction. In general, The requirements of Chapter 60 773 (Stormwater Management Ordinance) of the WQIAArlington County Code may not be sufficient to meet the 774 requirements of this Chapter. The water quality impact assessment shall also demonstrate that there is either a forty 775 percent (40%) reduction of pollutant loads from the post-development condition for sites with an RPA buffer that 776 consists primarily of natural vegetation (trees, shrubs, and ground cover), or there is a net reduction in pollutant 777 loads over the pre-development condition and a net improvement in RPA buffer vegetation and riparian habitat for 778 sites with an RPA buffer that contains impervious cover and/or little natural vegetation. Actual site requirements 779 will be determined during the review of the water quality impact assessment as well as by any other requirements 780 applicable to the site (e.g., pollutant removal requirements under § 61-10.F) under this chapter. 781

782 There shall be two (2) levels of water quality impact assessments: a minor assessment and a major 783

assessment. Information shall be provided using the forms and guidance provided by the County ManagerDirector. 784

Upon issuance of an inspection report denoting receipt of a sworn complaint by the project inspector of a 397 violation of the terms of the permit or any applicable law, the County Manager or his designee, in conjunction with 398 or subsequent to a notice to comply, as specified in § 57-9 above, may issue an order requiring that all or part of the 399 land-disturbing activities permitted on the site be stopped until the specified corrective measures have been taken, 400 or, if land-disturbing activities have commenced without an approved plan, as required by this chapter, then all of 401 the land-disturbing activities shall be stopped until an approved plan or any required permits are obtained. Where the 402 alleged noncompliance is causing or is in imminent danger of causing harmful erosion of lands or sediment deposits 403 in waters within the watersheds of the Commonwealth, or where the land-disturbing activities have commenced 404 without an approved plan or any required permits, such an order may be issued without regard to whether the permit 405 holder has been issued a notice to comply, as specified in § 57-9 above. Otherwise, such an order may be issued 406 only after the permit holder has failed to comply with such a notice to comply, as specified in § 57-9 above. The 407 order shall be served in the same manner as a notice to comply, as specified in § 57-9 above, and shall remain in 408 effect for a period of seven (7) days from the date of service pending application by the enforcing authority or 409 permit holder for appropriate relief to the Circuit Court of Arlington County. The order for disturbance without an 410 approved plan or permits shall be served upon the owner by registered or certified mail to the address specified in 411 the land records of Arlington County, shall be posted on the site where the disturbance is occurring, and shall remain 412 in effect until such time as permits and plan approvals are secured, except in such situations where an agricultural 413 exemption applies. If the alleged violator has not obtained an approved erosion and sediment control plan or any 414 required permits within seven days from the date of the service of the order, the Virginia Department of 415 Environmental Quality or the County Manager or designee may issue a subsequent order to the owner requiring that 416 all construction and other work on the site, other than corrective measures, be stopped until an approved sediment 417 control plan and any required permits have been obtained. The subsequent order shall be served upon the owner by 418 registered or certified mail to the address specified in the permit application or the land records of the locality in 419 which the site is located. The owner may appeal the issuance of any order to the Circuit Court of Arlington County 420 or other appropriate court. Any person violating or failing, neglecting or refusing to obey an order issued by the 421 Virginia Department of Environmental Quality or the County Manager or designee may be compelled in a 422 proceeding instituted in the Circuit Court of Arlington County or other appropriate court to obey same and to 423 comply therewith by injunction, mandamus or other appropriate remedy. Upon completion and approval of 424 corrective action or obtaining an approved plan or any required permits, the order shall immediately be lifted. 425 Nothing in this section shall prevent the County Manager or his designee from taking any other permissible action. 426 (Ord.

Page 61: ATTACHMENT A RESOLUTION TO RATIFY AND AUTHORIZE

Attachment E The Runoff Reduction Method (RRM) computational methodology is significantly different from Arlington’s current method for determining stormwater compliance. Two key differences are that the County’s current requirements consider only impervious cover, and calculate the treatment requirements in terms of area to be treated. The RRM method considers lawn area as well and calculates the treatment requirements in terms of phosphorus loading. Another important difference is that the minimum capacity for stormwater management facilities (i.e., how much rainfall each facility must be designed to capture) is higher under the new RRM requirements. In addition, the County currently allows pervious paving and vegetated roof systems to be counted as fully pervious surfaces—a generous credit to encourage their use. The new RRM methodology, although providing important runoff reduction credits for pervious paving and vegetated roof systems, more conservatively pro-rates these systems as partially pervious. The increased level of effort for compliance with the new RRM method is therefore difficult to compare in a general or uniform way with Arlington’s current requirements. Analysis of previously approved projects suggests that the increased level of effort can be relatively small (e.g., 10 percent more impervious area treated) to significant (e.g., greater than 50 percent more impervious area treated). In general, the greater the impervious cover increase and the less permeable the soils, the greater the effort that will be needed to comply. Also, as noted above, the increased minimum capacity for stormwater management facilities under the RRM means that, in addition to increased areas of treatment, larger facilities will also be needed. In addition, the new State requirements set a 20 percent net pollutant reduction requirement for redevelopment activities with one (1) acre or more of land disturbance, compared with a 10 percent standard for projects that disturb at least 2,500 square feet of land but less than one (1) acre of land. The current standard is 10 percent for all redevelopment activities. New development (where land is currently vacant) has a different standard—which is similar under existing and proposed requirements. Approximately 90 percent of the development in Arlington is redevelopment and also involves less than one (1) acre of land disturbance. The new State regulations and Arlington’s proposed Stormwater Management Ordinance also specify new performance standards to protect downstream properties, stormwater pipes, and stream channels from flooding and erosion. Staff’s analysis suggests that these flood/channel protection requirements also can be more stringent than current requirements. And, like the RRM, the computational method will change under the proposed ordinance, making direct comparison with existing requirements more complicated. Staff’s analysis of past projects suggests that the County’s current requirements are as stringent as the new requirements in many cases—but not in all cases. An important benefit of the new computational methodology is the ability to account for runoff reduction practices (e.g., permeable paving, bioretention, vegetated roofs, etc.) in the flooding/erosion compliance calculations, rewarding the runoff reduction benefits these strategies provide.
