The applicant proposes to install an approximately 400-foot-long, 12-inch water line through the subject properties. The scope of work will take place within the Fields Natural Area, and the water line will be installed by directional boring, which will avoid impacts to a nearby locally significant wetland and its 50-foot vegetated corridor. However, the work will involve minimal ground disturbances or land form alterations in an adjacent vegetated corridor, and the FEMA special flood hazard area.Accordingly,this application is being processed through a Type I sensitive lands review.The applicant also proposes to remove seven (7) native trees that are located in a significant tree grove and significant habitat area. The subject properties are located in the Parks and Recreation (PR) Zone, and the project is considered to be an underground basic utility,which is allowed in the PR Zone. SECTION IV. APPLICABLE REVIEW CRITERIA AND FINDINGS 18.510 Sensitive Lands: 18.510.020 Applicability E. Administrative sensitive lands review. 1. Administrative sensitive lands reviews within the special flood hazard area (excluding the floodway), drainageway, slopes that are 25 percent or greater, and unstable ground are processed through a Type I procedure, as provided in Section 18.710.050, for the following actions: a. The repair,reconstruction,or improvement of an existing structure or utility,the cost of which is less than 50 percent of the market value of the structure prior to the improvement or the damage requiring reconstruction. b. Actions within the special flood hazard area: i. The construction of accessory structures up to 528 square feet in size; and ii. Any landform alternation involving up to 50 cubic yards of material. c. Actions within drainageways and slopes that are 25 percent or greater, and unstable ground: SLR2020-00006 Milton Court Water Line 2 i. Minimal ground disturbances or landform alterations involving 10 to 50 cubic yards of material;and ii. Building permits for accessory structures that are 120 to 528 square feet in size. 2. The approval authority will approve, approve with conditions, or deny a sensitive land review application using the standards and approval criteria Sections 18.510.040,18.510.050, 18.510.070 and 18.510.080. The applicant proposes to install an approximately 400-foot-long, 12-inch water line through the subject properties. The scope of work will involve minimal ground disturbances or land form alterations involving less than 50 cubic yards of material in a vegetated corridor associated with a drainageway and in the FEMA special flood hazard area. However, the impacted vegetated corridor area does not affect the drainageway;therefore,the findings below will only evaluate-the project's impacts in the special flood hazard area. This proposal requires a sensitive lands review, and is being processed through a Type I procedure.The applicable standards and approval criteria are addressed in the findings below. 18.510.030 Administrative Provisions A. Interagency coordination. The approval authority will review all applications for a sensitive lands review to determine that all necessary approvals be obtained from those federal, state,or local governmental agencies,from which prior approval is also required. As provided in CWS "Design and Construction Standards," the necessary permits for all "development" must comply include a CWS service provider letter, which specifies the conditions and requirements necessary, if any, for an applicant to comply with CWS water quality protection standards and for the agency to issue a stormwater connection permit. The applicant obtained a Service Provider Letter from CWS on August 27,2020(CWS file 19-002417).Clean Water Services determined there are sensitive areas present both on and off the site,and that the vegetated corridor is 50 feet wide.The agency approved of the proposal,subject to conditions related to water quality protection requirements,induding enhancement of the vegetated corridor.A copy of the Service Provider Letter is attached to this derision. Additionally, staff has included a condition of approval for the applicant to comply with all CWS conditions.This standard is met. 18.510.040 General Provisions for Special Flood Hazard Areas A. Review. The approval authority will review all applications to determine whether proposed building sites will minimize the potential for flood damage. B. Special flood hazard. The areas of special flood hazard identified by FEMA in a scientific and engineering report entitled "The Flood Insurance Study for Washington County, Oregon and Incorporated Areas effective October 19, 2018" with accompanying Flood Insurance Map is hereby adopted by reference and declared to be a part of this ordinance. C. Base flood elevation data.When base flood elevation data has not been provided in compliance with Subsection 18.510.040.B, the approval authority will obtain, review and reasonably utilize any base flood elevation and floodway data available from a federal, state or other source, in order to administer Subsections 18.510.040.M and N. D. Test of reasonableness.Where elevation data is not available either through the flood insurance study or from another authoritative source,applications for building permits will be reviewed to assure that the potential for flood damage to the proposed construction will be minimized.The test of reasonableness is a local judgment and includes use of historical data,high water marks, photographs of past flooding,etc.,where available. Failure to elevate at least 2 feet above grade in these sensitive land areas may result in higher insurance rates. E. Resistant to flood damage. All new construction and substantial improvements, including manufactured homes, must be constructed with materials and utility equipment resistant to SLR2020-00006 Milton Court Water Line 3 flood damage. F. Minimize flood damage. All new construction and substantial improvements, including manufactured homes, must be constructed using methods and practices that minimize flood damage. The scope of work is located in the 1,EMA special flood hazard area, but is not located in the floodway. The applicant proposes to install an approximately 400-foot-long, 12-inch water line through the subject properties,which will result in minimal ground disturbances or land form alterations involving less than 50 cubic yards of material in the special flood hazard area.The applicant's proposal does not involve any new structures or buildings. The new water line will be placed underground via directional boring, and the applicant submitted plans that were certified by a registered professional engineer. Accordingly,staff finds that the new water line will be constructed using methods and practices that minimize flood damage. These standards are met. H. Water supply systems. All new and replacement water supply systems must be designed to minimize or eliminate infiltration of floodwater into the system. The new water line will be placed underground and will be installed via directional boring.The applicant also submitted plans that were certified by a registered professional engineer,which demonstrate that the new water line will be designed to minimize or eliminate infiltration of floodwater into the system. This standard is met. 18.510.070 Sensitive Lands Applications B. Within the special flood hazard area. The approval authority will approve or approve with conditions an application for sensitive lands review within the special flood hazard area when all of the following criteria are met: 1. Compliance with all of the applicable requirements of this title; As demonstrated through the findings in this decision, the applicant's proposal is in compliance with all applicable requirements of this Title.This standard is met. 2. Land form alterations must preserve or enhance the special flood hazard area storage function and maintenance of the zero-foot rise floodway must not result in any encroachments, including fill, new construction, substantial improvements and other development unless certified by a registered professional engineer that the encroachment will not result in any increase in flood levels during the base flood discharge; a. If in the floodway and no-rise requirement is met,the development will comply with all applicable flood hazard reduction provisions. The subject site is located in the FEMA special flood hazard area,but is not located in the floodway. The new water line will be placed underground via directional boring, and will result in minimal ground disturbances or land form alterations involving less than 50 cubic yards of material in the special flood hazard area.The applicant also submitted plans that were certified by a registered professional engineer, which demonstrate that the new water line will be designed to preserve the special flood hazard area storage function, and will not result in any increase in flood levels during the base flood discharge. This standard is met. 3. Land form alterations or developments within the special flood hazard area are allowed only in areas designated as commercial or industrial on the comprehensive plan land use map, except that alterations or developments associated with community service uses, utilities, or public support facilities are allowed on residentially zoned properties subject to SLR2020-00006 Milton Court Water Line 4 applicable zoning standards; The subject site is designated as Open Space on the Tigard Comprehensive Plan Land Use Map,and is zoned Parks and Recreation (PR). The proposal is for a utility,and an underground basic utility is allowed in the PR Zone.This standard is met. 4. Where a land form alteration or development is allowed to occur within the special flood hazard area it will not result in any increase in the water surface elevation of the 100-year flood; The new water line will be placed underground via directional boring,and will result in minimal ground disturbances or land form alterations involving less than 50 cubic yards of material in the special flood hazard area.The applicant also submitted plans that were certified by a registered professional engineer, which demonstrate that the new water line will not result in any increase in the water surface elevation of the 100-year flood.This standard is met.
