The project was determined to be exempt from a Shoreline Substantial Development permit as the project is for normal maintenance and repair of existing structures (WAC 173 -27 -040 2.(b)). The repairs are as follows: Site 1: 17450 West Valley Highway Outfall 'Site 1 is located on the west side of West Valley Highway across the street from Gai's Bakery Thrift Store. The existing 12 -inch CMP outfall pipe has been up heaved by an existing tree adjacent to the pipe causing a backwater condition in upstream catch basins. The project entails removal of an existing cottonwood tree that has damaged the outfall pipe, removal and replacement of approximately 30 linear feet (LF) of the existing outfall pipe, and the installation of a backflow prevention device. Riprap and quarry spalls will be placed at the pipe outfall to prevent future erosion. All work is above the ordinary high water mark, and no heavy machinery will be required below the top of the bank. Three (3) 5 gallon cottonwood trees will be planted as mitigation for the removed tree. Site 2: 631 Strander Blvd. Outfall: Site 2 is located on the east side of the Green River Trail at the south end of the 631 Strander Blvd. property and along the west side of the Green River. The existing 24 -inch outfall pipe is broken and has caused localized erosion to the stream bank. The outfall is located within the U.S. Army Corp of Engineers (COE) levy along the Green River. The project entails removing and replacing approximately 30 LF of the outfall pipe and installing a new backflow prevention device. All work is above the ordinary high water mark and no heavy machinery will be required below the top of the bank.

Site 3: Christensen Road Outfall: Site 3 is located on the east side of Christensen Road just south of I -405. The existing 18 -inch outfall pipe and flap gate have failed causing erosion to the stream bank. The outfall is located within the COE levy along the Green River. The project entails removing and replacing approximately 30 LF of the outfall pipe and installing a new backflow prevention device. Existing rock outfall protection will be replaced. All work is above the ordinary high water mark and no heavy machinery will be required below the top of the bank for installation. All disturbed areas adjacent to the pipe and outfall protection will be restored with appropriate native species. Twenty live willow stakes will be planted at this site. Only willows are permitted along this levee per the US Army Corps of Engineers. Site 4: 6410 S. 143rd Street Outfall: Site 4 is located at the north end of the 6410 S. 143rd St. property along the west side of the Duwamish River. The existing 24 -inch outfall pipe and flap gate have failed causing erosion to the stream bank. The project entails removing and replacing approximately 30 LF of the outfall pipe and installing a new backflow prevention device. All work is above the ordinary high water mark and no heavy machinery will be required below the top of the bank for installation. All disturbed areas adjacent to the pipe and outfall protection will be stabilized with erosion control fabric and native hydroseed. Site 5: 14220 Interurban Ave. S. Outfall: Site 5 is located at the north end of the 14220 Interurban Aven S. property along the west side of the Duwamish River. The project entails re- grading the existing drainage ditch. Portions of the work are above the ordinary high water mark, and no heavy machinery will be required below the top of the bank for installation. All disturbed areas adjacent to the pipe and outfall protection will be stabilized with erosion control fabric and native hydroseed.

The maximum embankment slope is approximately 35 %. Localized slopes due to outfall erosion are nearly vertical and less than 6 feet high. The soils appear to be silty with cobbles, most likely a combination of original stream bank and imported embankment material from past residential /municipal construction. Minor excavation will be required to install the new pipe sections and provide for erosion protection at each of the outfall locations. Trench excavation and backfill will generally match existing grades. Native soils will be used in lieu of imported trench backfill where determined suitable by the inspector. The applicant anticipates the need for additional material to replace unsuitable soils and for minor grading to match existing grades. All import materials will be from a state approved source. Some clearing of vegetation will be required to install the new pipes and place the riprap. The vegetation to be cleared is mostly Himalayan Blackberry, Japanese CL Page 3 of 8 06/09/2006 4:44 PM c: \mydocs \2006 PW Outfall Repairs \E06 -008 StaffrRt.doc • • SEPA Review — E06 -008 Public Works 2006 Storm Water Outfall Projects June 7, 2006 Knotweed, and invasive grasses. One cottonwood tree will be removed and replaced with three replacement trees. Construction will be conducted during the dry summer months using erosion control best management practices, as described in the King County Surface Water Design Manual and City regulations. Disturbed areas will be restored with seed and suitable native plant materials after construction is complete. Native plant species (site 1 & 3) will be water tolerant such as willow, red -osier dogwood and /or cottonwood. Air Minor dust and internal combustion engine emissions associated with use of construction equipment will occur only during construction of the project. Best management practices will be implemented during construction activities to reduce and control dust and air emissions. These practices may include covering soil stockpiles, sweeping or washing paved surfaces, minimizing exposed areas and using construction machinery equipped with standard mufflers. Water All of the project sites are adjacent to and directly discharge into the Green/Duwamish River. The purpose of the five projects is to repair storm drainage outfalls. The project is exempt from a shoreline substantial development permit as the projects are for normal maintenance and repair of existing facilities. For each of the projects, up to 10 cubic yards may be removed from the existing river bank to provide a firm foundation for the new outfall pipe. Fill material will be suitable native soils or from a state approved source. The total area affected will be about 400 square feet at each site, for a total of 2,000 square feet overall. Temporary bypass of flows will be required to install outfall protection. There are no flows through the outfall pipes when there is no precipitation. There will there be no surface water or ground water withdrawals or diversions. The project site lies within the 100 - year floodplain. No discharges of waste materials to surface waters will occur. No modifications to current collection and disposal of runoff will occur. Appropriate best management practices will be used to prevent sediment transport into the Green/Duwamish River. Plants The repairs to the storm drainage outfalls will disturb approximately 2,000 square feet of grass and Himalayan blackberry.

There are no known threatened or endangered vegetation species present on the project sites. There is also no known critical habitat for vegetation on the project sites. Disturbed areas will be restored with seed and suitable native plant materials after construction is complete. A coconut fiber mat and/or geotextile will underlie all disturbed areas prior to planting. Native species will be water tolerant such as willow, red -osier dogwood and/or cottonwood. One cottonwood tree is being removed and will be replaced by 3 cottonwood trees planted approximately 500 feet upstream from the removed tree, which has interfered with the functioning of the outfall. Mitigation plantings proposed are consistent with recent recommendations of the WDFW area habitat biologist. Animals The SEPA Checklist notes that songbirds, snakes, rodents, salmon and trout have been observed on or near the site. Chinook salmon and bull trout are present in the River, which is a migration route for the salmon. Restoration will be with native plants to provide additional shade against the riverbank. As a result of the intended maintenance work, current riverbank erosion at the five project sites will cease and localized turbidity levels will improve. Energy/Natural Resources The completed project will not require any type of energy for operation. Environmental Health Construction noise will occur during regular hours of 7:00 a.m. to 6:00 p.m. Construction equipment will be equipped with mufflers and all operations will be in accordance with City of Tukwila noise ordinances. Land/Shoreline Uses The project sites are all located on City right -of -way easements along the Green River Trail. The zoning and comprehensive plan designations for the properties adjacent to the five projects are as follows: Site 1: Commercial /Light Industrial Site 2: Tukwila Urban Center CL Page 5 of 8 06/09/2006 4:44 PM c: \mydocs \2006 PW Outfall Repairs \E06 -008 Staff rRt.doc • • SEPA Review — E06 -008 Public Works 2006 Storm Water Outfall Projects June 7, 2006 Site 3: Tukwila Urban Center Site 4: Commercial /Light Industrial Site 5: Commercial/Light Industrial The shoreline designation is Urban. No one will work on the site once the projects are complete and no one is being displaced by construction of the outfall repairs. The work will take place along a designated recreation trail, the Green River Trail. Traffic control will be required on the bike trail and is included in the contract specifications. Limited closures of the trail may be required but has not been determined yet. If a trail closure is necessary then a detour will be provided. It is hoped that all or most of the work can be done with flaggers on the trail. If a detour is required, the contractor will coordinate with City's Parks Department. Historic /Cultural Preservation There are no places or objects listed on or proposed for national state or local preservation registers on or near the five sites. Transportation The five repair projects will not generate new traffic other than the traffic from vehicles working on the storm water repairs. Public Services The repair projects will not result in an increased need for public services. Utilities The Department of Public Works will continue to monitor the outfall sites and make repairs as needed in the future. No utilities will be required by the project. Public Comments During the Notice of Application comment period Karen Walter, Watershed and Land Use Team Leader for the Muckleshoot Indian Tribe contacted the City and asked three questions. Staff responses to her questions are in italics: CL Page 6 of 8 06/09/2006 4:44 PM c: \mydocs \2006 PW Outfall Repairs \E06 -008 Staff rRt.doc • • SEPA Review — E06 -008 Public Works 2006 Storm Water Outfall Projects June 7, 2006 1. What will happen to the cottonwood tree that is proposed to be removed from Site 1? It appears to be large enough that it should be placed in the River as mitigation for the loss of wood recruitment. The tree will be removed and not used in the river. After discussions with the Washington State Department of Fisheries, it was concluded that cottonwood trees tend to rot too fast and therefore do not make ideal woody debris. For mitigation purposes we will plant three new cottonwood trees (5 gallon size) approximately 500 feet upstream and closer to the river on an existing bench. This location will keep them from affecting West Valley Highway and provide more shade and wood recruitment to the river once they are mature. 2. Is the Site 3 outfall going to affect Gillian Creek? If so, is the new flap gate going to be able to pass fish? Site 3 is a separate outfall and not connected to the Gilliam Creek outfall which is located about 500 feet downstream. The outfall being reconstructed is high on the bank and only serves as a storm drainage discharge for a few businesses immediately to the east. A flap gate will be installed to prevent floodwaters from flowing through the levee and this will prevent entree of fish into the system during flood events. 3. Are any of the other sites affecting streams in the project area or do they solely convey stormwater? All five sites are storm discharges only. These responses were e- mailed to Ms. Walter. In a subsequent communication Ms. Walter stated "Thank you for responding to my questions. Based on your responses, my only outstanding concern is that I disagree with WDFW's apparent assessment that the large cottonwood in question has no value as wood for instream fish habitat. While the tree may rot faster than a Douglas Fir or Cedar Tree, having wood versus not having wood is better for the Lower Green River, which as you know lacks wood. It takes a long time for trees to grow and recruit as instream wood to grow, and it will be at lest 75 -100 years before the 3 planted cottonwoods recruit to the river, this project has a temporal issue to address. Again, I would suggest that the City keep this tree to be used to create instream habitat, perhaps as part of a project already planned by the City or other agency that needs wood." The applicant, Tukwila Public Works Department, discussed the possibility of using the cottonwood tree at a future time for instream fish habitat with its consultant, KPG. The consultant recommended that if money is going to be spent to anchor logs for fish habitat, the logs should be ones that last longer than cottonwood. It costs approximately $5,000 - CL Page 7 of 8 06/09/2006 4:44 PM c: \mydocs \2006 PW Outfall Repairs \E06 -008 Staff rRt.doc SEPA Review — E06 -008 Public Works 2006 Storm Water Outfall Projects June 7, 2006 $7,000 to anchor large woody debris to the stream bank. The City has stockpiled some cedar logs with root balls for placement in the river for future instream projects. The applicant will plant 20 willow stakes at site #3 as additional mitigation for the removal of the cottonwood tree. The City is in the process with WRIA 9 of securing funding for the purchase of the Carrasino Property, known as the Duwamish Gardens site. This property is located on the right bank of the Duwamish River just south of East Marginal Way South and S. 115th Street. This project will create a pocket estuary on this 2.16 -acre site. At the time the restoration project is constructed, previously stockpiled woody debris will be included in the project.

Sorry about that. Anyway, the Muckleshoot Indian Tribe Fisheries Division has reviewed the Notice of Application and environmental checklist for the above referenced project. We have some questions. 1. What will happen to the cottonwood tree that is proposed to be removed from Site 1? It appears to be large enough that it should be placed in the River as mitigation for the Toss of wood recruitment. 2. Is the Site 3 outfall going to affect Gillian Creek? If so, is the new flapgate going to be able to pass fish? 3. Are any of the other sites affecting streams in the project area or do they solely convey stormwater? As you can see, we need additional information before we can provide any technical comments to this project. Please note that the fish window overlaps with the timeframe when the Tribe may be fishing in the area; therefore, it will be important to coordinate the construction of this project to avoid interfering with the Tribe's fishing.

Based on this response, it appears that the City will be disposing of the existing cottonwood tree on Site 1 and not putting it back into the river as we recommended. The City's position appears to be based on the cost of anchoring large wood into the Duwamish River and the potential shorter life span of a cottonwood tree compared to a cedar log. We have two follow -up comments. First, please note that according to Collins and Sheikh (2005;p.ii), "hardwood dominated riparian riverine forests, as reconstructed from General Land Office field notes from the 1860s. Trees that were both abundant and commonly attained a large diameter, and so would most commonly have contributed large wood to channels, include black cottonwood (Populus trichocarpa) and bigleaf maple (Acer macrophyllum), and secondarily western red cedar (Thuja plicata) and Douglas Fir (Pseudotsuga menziesii)." So based on a historical record, cottonwood trees would have recruited and been found in the Duwamish. Second, if the City can't use this tree in its Carrasino property project, then it should work with other WRIA 9 jurisdictions to see if some other jurisdiction can use this tree. For example, it sees that the King County Rivers group would want this tree. Please note that there is a temporal impact (the timeframe that is the difference between the age of the existing tree and the age of the cottonwoods to be planted) that will occur with the removal of the existing cottonwood tree that will not be fully mitigated by replacing this tree with 3 -5 gallon cottonwood trees and 20 willow stakes.

Based on your responses, my only outstanding concern is that I disagree with WDFW's apparent assessment that the large cottonwood in question has no value as wood for instream fish habitat. While the tree may rot faster than a Douglas Fir or Cedar Tree, having wood versus not having wood better for the Lower Green River, which as you know lacks wood. It takes a long time for trees to grow and recruit as instream wood to grow, and it will be at least 75 -100 years before the 3 planted cottonwoods recruit to the river, this project has a temporal issue to address. Again, I would suggest that the City keep this tree to be used to create instream habitat, perhaps as part of a project already planned by the City or other agency that needs wood.

Thanks - Ryan 1. What will happen to the cottonwood tree that is proposed to be • removed from Site 1? It appears to be large enough that it should be placed in the River as mitigation for the loss of wood recruitment. The tree will be removed and not used in the river. After discussions with the Washington State Department of Fisheries, it was concuded that Cottonwood trees tend to rot too fast and therefore do not make ideal woody debris. For mitigation purposes, we will plant three new cottonwood trees (5 gallon size) approximately 500' upstream and closer to the river on an existing bench. This location will keep them from affecting West Valley Highway and provide more shade and wood recruitment to the river once they are mature. 2. Is the Site 3 outfall going to affect Gillian Creek? If so, is the new flapgate going to be able to pass fish? Site 3 is a seperate outfall and not connected to the Gilliam Creek outfall which is located about 500' downstream. The outfall being reconstructed is high on the bank and only serves as a storm drainage discharge for a few businesses imediately to the east. A flap gate will be installed to prevent floodwaters from flowing through the levee and this will prevent entree of fish into the system during flood events. 3. Are any of the other sites affecting streams in the project area or do they solely convey stormwater? All five sites are storm discharges only. »> Carol Lumb 05/12/06 03:47PM >» Hi Ryan: I'm forwarding an e-mail from the Muckleshoot Tribe with questions about the outfall project.

Ms. Walter's continues to insist that we use the cottonwood tree as woody debris on this site or another restoration site. KPG and Larry Fisher feel that cottonwood trees do not make good woody debris since they tend to rot faster and then other trees. During the SEPA stage we mentioned this fact and left it open that we could bring in another species for woody debris but the discussion always returned to using the tree that is to be removed either at this or another site. I have sent Larry Fisher an email requesting permission to drop the tree at the site and anchor it in place. Since this was rejected early on I am not sure how he will react. I will let you know what Larry says.

Based on this response, it appears that the City will be disposing of the existing cottonwood tree on Site 1 and not putting it back into the river as we recommended. The City's position appears to be based on the cost of anchoring large wood into the Duwamish River and the potential shorter life span of a cottonwood tree compared to a • cedar log. We have two follow -up comments. First, please note that according to Collins and Sheikh (2005;p.ii), "hardwood dominated riparian riverine forests, as reconstructed from General Land Office field notes from the 1860s. Trees that were both abundant and commonly attained a large diameter, and so would most commonly have contributed large wood to channels, include black cottonwood (Populus trichocarpa) and bigleaf maple (Acer macrophyllum), and secondarily western red cedar (Thuja plicate) and Douglas Fir (Pseudotsuga menziesii)." So based on a historical record, cottonwood trees would have recruited and been found in the Duwamish. Second, if the City can't use this tree in its Carrasino property project, then it should work with other WRIA 9 jurisdictions to see if some other jurisdiction can use this tree. For example, it sees that the King County Rivers group would want this tree. Please note that there is a temporal impact (the timeframe that is the difference between the age of the existing tree and the age of the cottonwoods to be planted) that will occur with the removal of the existing cottonwood tree that will not be fully mitigated by replacing this tree with 3 -5 gallon cottonwood trees and 20 willow stakes. The willow stakes will not provide large wood back to the river and the river is well documented for lacking wood for fish habitat.

I understand that you are concerned about the decision not to utilize the removed mature cottonwood tree for instream fish habitat at some future time. While the City does not plan to utilize the cottonwood tree, we do have a stockpile of cedar logs with root balls that will be used at future fish habitat projects. Given the cost of anchoring large woody debris to the stream bank, it is more cost effective for the City to use wood material that will last as long as possible, hence the decision to use cedar logs rather than save the cottonwood tree for in -river use. The City is in the process with the WRIA 9 program staff of securing funding for the purchase of the Carrasino property located on the right bank of the Duwamish River just south of East Marginal Way South at its intersection with S. 115th Street. The project will create a pocket estuary on this 2.16 -acre site. At the time the estuary is constructed, previously stockpiled woody debris will be included in the project to provide fish refuge. In addition to the three cottonwood trees that will be planted near the tree that is being removed, 20 willow stakes will be planted at site 3 as additional mitigation for the removal of the cottonwood tree.

Trail access: Traffic control will be required on the bike trail and is included in the contract specifications. Limited closures of the trail may be required but this will not be determined until the contractor proposes their method of work. If a trail closure is necessary then a detour will be provided. We are hopeful that all or most of the work can be done with flaggers on the trail. Coordination will be done with the City's Parks Department if a detour is required. 2. Clearing Invasive Plants: Only vegetation that interferes with the reconstruction of these outfalls will be removed. 3. Added Plantings at Site 3: Site 3 will have 20 live willow stakes planted. Only willows are permitted along this levee per USACOE guidelines for levees. ✓ 4. Staff Report Sites 1 -5: All construction will be above the ordinary high water mark. 5. Land/Shoreline Uses: "No disruption of trail usage" should be changed to "minor construction related disruption" in the last sentence of this section. '/ 6. The City is in the process with WRIA 9 of securing funding for the purchase of the Carrasino Property known as Duwamish Gardens. This property is located on the right bank of the Duwamish River just downstream of East Marginal Way South. The project will create a pocket estuary on this 2.16 -acre site. At the time of construction, previously stockpiled woody debris will be included in this project. 6/8/06 Ryan; Attached is my first draft of the staff report. A couple more questions for you: • It looks like work on the outfall repairs may impede access to the bike trail — do you have a plan for warning trail users of detours, or setting up setting up signage that warns users of trail closures on certain days ? ? ?? • where the outfall repairs are taking place, will PW clear out all the invasive plants that are around the outfall (like the blackberries)? • On page 5 of the checklist, under "h. ", you say native plant species that are planted will be water tolerant, and indicate plantings will be at sites 1 and 3 — will there be plantings at site 3? If you plant additional trees in lieu of placing LWD is that maybe the site to do it ?? Please review in particular pages 6 & 7 where I discuss Karen Walter's comments. On page 7 there are some gaps that need to be filled in — also check my cost estimate for placing LWD — I got back to my desk and had forgotten the amount you told me. Please give me any edits you want. Maybe we could meet after you've had a chance to review. Thanks.

Be specific in describing the types of changes you want made to the plans. When referencing codes, please identify the actual requirement and plan change needed. The Planning Division review does not supplant each department's ability to administer its own regulations and permits. However, project consistency at the Planning review stage is important to minimize significant later design changes. More than minimal design changes require further Planning Commission review, even if alteration is required to satisfy a City requirement. This further review is typically a minimum 60 -day process. Requirements based on SEPA (e.g., not required by an adopted development regulation) MUST identify the impact being mitigated, the policy basis for requiring mitigation, and the method used to calculate the mitigation required. Calculations of project impacts and the mitigation required (e.g., water capacity, road level of service analyses, or turning analyses) may be required of the applicant.

Brief, complete description of the proposal, including the proposed uses and the size of the project and site: The outfall repair program includes the following 5 project sites: Site 1— 17450 West Valley Highway Outfall Site 1 is located on the west side of West Valley Highway across the street from Gai's Bakery Thrift Store. The existing 12 -inch CMP outfall pipe has been up heaved by an existing tree adjacent to the pipe causing a backwater condition in upstream catch basins. The project entails removal and replacement of the existing cottonwood tree, approximately 30 LF of the existing outfall pipfiand the installation of a backflow prevention device. Riprap and quarry spalls will be placed at the pipe outfall to prevent future erosion. All work is within the ordinary high water mark; however, no heavy machinery will be required below the top of bank. Three (3) 5 gallon cottonwood trees will be included as mitigation 0 for the removed tree. won Suitr�lt 1v,Rt! Site 2 631 Strander Blvd Outfall 11 ht sdoSnn 4 Site 2 is located on the east side of the Green River Trail at the south end of the 631 Strander Blvd property and along the west side of the Green River. The existing 24" outfall pipe is broken and has caused localized erosion to the stream bank. The outfall is located within the Army Corp Levy along the Green River. The project entails removing and replacing approximately 30 LF of the outfall pipe, and installing a new backflow prevention device. All work is within the ordinary high water mark; however, no heavy machinery will be required below the top of bank for installation. All disturbed areas adjacent to the pipe and outfall protection will be stabilized with erosion control fabric and native hydroseed. 2 Site 3 — Christensen Road Outfall Site 3 is located on the east side of Christensen Road just South of 1-405. The existing 18" outfall pipe and flap gate have failed causing erosion to the stream bank. The outfall is located within the Army Corp Levy along the Green River. The project entails removing and replacing approximately 30 LF of the outfall pipe, and installing a new backflow prevention device. Existing rock outfall protection will be replaced. All work is within the ordinary high water mark; however, no heavy machinery will be required below the top of bank for installation. All disturbed areas adjacent to the pipe and outfall protection will be restored with appropriate native species. Site 4 — 6410 S 143rd Street Outfall Site 4 is located at the north end of the 6410 S 143rd Street property along the west side of the Duwamish River. The existing 24" outfall pipe and flap gate have failed causing erosion to the stream bank. The project entails removing and replacing approximately 30 LF of the outfall pipe, and installing a new backflow prevention device. All work is within the ordinary high water mark; however, no heavy machinery will be required below the top of bank for installation. All disturbed areas adjacent to the pipe and outfall protection will be stabilized with erosion control fabric and native hydroseed. Site 5 — 14220 Interurban Ave S Outfall Site 5 is located at the north end of the 14220 Interurban Ave S property along the west side of the Duwamish River. The existing drainage ditch is filled with sediment causing a backwater condition in upstream catch basins. The project entails re- grading the existing drainage ditch.

If your project involves grading and you have not prepared a Temporary Erosion and Sedimentation Control Plan specifically designed to retain 100 percent of the runoff (including during construction) from impervious surface or disturbed soils, answer Yes to this question. If your project is normally exempt under the Tukwila Municipal Code and would not require the preparation of a Temporary Erosion and Sedimentation Control Plan, BUT may still result in erosion or sediment transport off site or beyond the work area, answer Yes to this question. Please circle appropriate response. NO - Continue to Question 1 -3 Continue to Question 1 -3 1 -3 ill the project result in the construction of new impervious surfaces? Impervious surfaces include those hard surfaces which prevent or restrict the entry of water into the soil in the manner that such water entered the soils under natural conditions prior to development; or a hard surface area that causes water to run off the surface in greater quantity or at an increased rate of flow from the flow presented under natural conditions prior to development (see TMC Chapter 18.06, Tukwila Zoning Code, Page 18 -12). Such areas include, but are not limited to, rooftops, asphalt or concrete paving, compacted surfaces, or other surfaces that similarly affect the natural infiltration or runoff patterns existing prior to development. Please circle r appropriate response. Continue to Question 2 -0 (Page 2) YES - Continue to Question 1 -4 1 -4 Will your project generate stormwater from the creation of impervious surfaces that will not be infiltrated on site? For the purpose of this analysis, infiltration includes the use of a stormwater treatment and management system intended to contain all stormwater on site by allowing it to seep into pervious surface or through other means to be introduced into the ground. If your project involves the construction of impervious surface and does not include the design of a stormwater management system specifically designed to infiltrate stormwater, answer Yes to this question.
