This Alternative Environmentally Sensitive Area (AESA) Report is being submitted to the City of Denton under the Denton Development Code (DDC) Section 2.8.4 to request approval for impacts to Environmentally Sensitive Areas (ESA). This AESA Report proposes mitigation measures for the impacts required to construct two functioning stormwater control structures for the proposed industrial distribution center. Description of Overall Development The proposed Exeter - Martino Property project is approximately 105-acres in size located northwest of the intersection of Jim Christal Road and Western Boulevard in the City of Denton, Denton County, Texas (Figure 1). The proposed project includes the construction of two distribution warehouses with associated parking and driveways. Two stormwater control structures will be constructed as part of the project. The development impact area is approximately 84-acres. The current zoning for this tract is Heavy Industrial (Hl) which allows for the proposed development. Existing Site Description The project area consists of agricultural field utilized for cattle grazing with Mesquite thicket in the southwest portion. Kimley-Horn Environmental staff conducted a site visit to the project area on October 7, 2020 to confirm environmentally sensitive areas (ESA) mapped by the City of Denton. Prior to the site visit, Kimley- Horn reviewed the previously mapped and assessed ESAs as depicted on the City of Denton GIS. The ESAs, as depicted on the City of Denton GIS, are shown on Figure 2. ESAs associated with two assessments completed in 2007 and 2015 were depicted as follows: ESA07-0004: the assessment completed in 2007 removed 50-foot Riparian Buffer ESA, through the central portion of the site, extending from the southwest boundary to the northeast. ESAI 5-0013: the assessment completed in 2015 removed additional 50-foot Riparian Buffer ESA through the central portion of the site and along the western boundary extending to the northeastern corner of the site. The assessment also identified/confirmed existing 50-foot and 100-foot Riparian Buffer ESA in the southwest corner of the site. The FEMA 100-year floodplain surrounding the Riparian Buffer ESAs was desIgnated as Undeveloped Floodplain ESA. The ESAs were observed to be in similar condition to the 2015 ESA assessment during the October 2020 site visit. During the site visit, two stream features and two excavated ditches were observed within the property boundary. Both 100-foot and 50-foot Riparian Buffer ESAs were identified along the streams within the property boundary. The FEMA 100-year floodplain appeared to remain undeveloped. The onsite streams, ditches, and ESAs identified during the site reconnaissance are shown on Sheet 3. The habitat within the ESAs is as follows: Streams An ephemeral stream generally borders the southwestern boundary before veering offsite to the west. Based on historical data, it appears that the surface water flow was previously through the second. remnant stream to the east. The ephemeral stream was on average 10-feet wide and incised. Overall the stream was in Fair condition based on the Rapid Stream Assessment Exeter -Martino Property AESA Report January 2021 2 Technique (RSAT) evaluation performed during the ESA assessment. The remnant stream appears to act as a secondary channel and does not consistently carry stormwater flows. The remnant channel was 12-feet on average with ponded, non-flowing water, especially near its southern extent. Overall the stream was in Fa/rcondition based on the RSAT evaluation performed during the ESA assessment. Ditches Two ditches were observed extending to the north and northeast towards Western Boulevard. The ditches appeared to have been excavated around 2008 in association with the construction of Western Boulevard. Both features appear to convey stormwater from the property and surrounding land to the southwestern streams. The banks of the ditches were vegetated by Annual Marsh Elder (Iva annua), Rough Cocklebur (Xanthium strumarium) , and Annual Ragweed (Ambrosia artemisiifolia) followed by Broomweed (Gutierrezia sarothrae), Mesquite (Propsopis glandulosa) , and upland grasses. Riparian Buffer ESA The 100-foot Riparian Buffer was identified along the ephemeral stream and the 50-foot buffer was identified along the remnant stream within the property boundary. Riparian Buffer ESA to the south and west of the property boundary was removed through ESA assessments completed in 2012 (ESA12-0005), 2018 (ESA18-0019), and 2019 (ESA19-0016). The understory was generally open through the buffers, consisting primarily of upland grasses, small Mesquite and Black Willow (Salix nigra) saplings, and Annual Ragweed near the stream banks. The tree community (measuring 6- inches and larger at diameter breast height (DBH)) consisted primarily of Osage-orange (Maclura pomifera) , Mesquite, Honey Locust (Gleditsia triacanthos) , and Hackberry (Celtis laevigata) . Table 1 below summarizes the trees measured and tagged within the Riparian Buffer ESA. A full tree inventory completed concurrently with the ESA assessment in October 2020 is included as Attachment B. Table 1. Summary of trees tagged within the Riparian Buffer ESA area.

The Floodplain ESA is associated to FEMA 100-year floodplain Zone AE. The vegetation outside of the Riparian Buffer ESAs is primarily Mesquite thicket consisting of Mesquite trees and saplings surrounded by upland grasses. Table 2 below summarizes the trees measured and tagged within the Undeveloped Floodplain ESA. It is important to note that the tree data in the Table 2 also includes the trees identified within the Riparian Buffer ESA. Exeter -MaRino Property AESA Report January 2021 3 Table 2.

The proposed structures would consist of excavating a channel that will direct stormwater from an outfall, located outside of the ESAs, to the adjacent stream channels. Consolidating the stormwater into the respective channels allows for efficient site layout of the two warehouse buildings by eliminating the need for addItional stormwater detention to prevent downstream erosion. Grading required for the construction would be limited to the minimum necessary for the channel construction: approximately 0.40-acres within the Riparian Buffer and approximately 0.53-acres in the Undeveloped Floodplain for a total of 0.93-acres of impacts within the ESAs. Figure 4 shows the proposed impacts to both ESAs. Impacts are also proposed to the Riparian Buffer and Undeveloped Floodplain ESAs with the expansion of Jim Christal Road. Jim Christal Road are identified on the City Mobility Plan; therefore, per the DDC the roadway improvements are a permitted activity within the ESAs and do not require an approved AESA plan. Plans to restore the area to minimize erosion and promote recovery of the ESA will be provided in the Erosion Control Plan within the Civil Engineering Plans. Additional project information is available from City of Denton Case Number ESA20-0027, ZCP20-0052, and PP20-0028 within ProjectDox. The preIIminary plat has not yet been approved by the City of Denton, but it is anticipated to be heard by Planning and Zoning Commission on January 6, 2021. Notification and Review This AESA Report explaining the mitigation measures for impacts to ESAs will be provided to the City of Denton for formal notification of the activity and review of the proposed restoration activity. Affected Environment and Summary of Impacts Figure 3 shows the observed Riparian Buffer and Undeveloped Floodplain ESAs associated with stream channels through the southwestern corner of the site. The total Riparian Buffer ESA covers approximately 3.3-acres and the Undeveloped Floodplain ESA covers approximately 6.6-acres within the property boundary. The Riparian Buffer ESA is almost completely within the Undeveloped Floodplain ESA. The project is proposing to construct two stormwater drainage channels within the onsite Riparian Buffer and Undeveloped Floodplain ESAs. One of the drainage channels also intersects the Undeveloped Floodplain ESA. The drainage channels will consist of grading a pathway from a stormwater outfall to the adjacent stream channel to prevent erosion from increased overland flow. The location and size of these Exeter .Martino Property AESA Report January 2021 4 channels have been determined by evaluating the proposed trapezoidal channel grading using the Modified Rational Method developed flows as per the City of Denton requirements. AU vegetation within the path of the channels will be removed during the initial construction; however, the impacts will be limited to the minimum extent necessary to construct a functional drainage pathway. The proposed impacts from the construction of the drainage channels are limited to 0.40-acres in the Riparian Buffer ESA and 0.53-acres of Undeveloped Floodplain ESA for a total of 0.93-acres of impacts within the development area. The total impacts are shown on Figure 4. Based on the tree inventory completed concurrently with the ESA assessment in October 2020, tree species within the impact area included Mesquite, Honey Locust, Hackberry, and Osage-orange. The forest within the riparian buffer was primarily open with little understory. The herbaceous cover consisted of ragweed near the stream channels and upland grasses. The trees to be removed are described in Table 3 below. The proposed trees to be removed total 81.5-caliper inches from five trees. However, the one tree within the northern impact area was a large Osage-orange in declining health condition. The proposed healthy trees to be removed total 36.5-caliper inches from four trees. The four healthy trees make up approximately 2% of the total healthy trees within the onsite ESAs. Table 3. Tagged trees within the proposed impact area.

Vegetation will be removed during the initial construction of the drainage structures. No additional adverse impacts to the streams or surrounding ESAs are expected from the construction. Following the construction of the drainage channels, a contractor will be instructed by Exeter to seed native grasses within the channels (impact areas identified on Figure 4). Once revegetated, the resulting AESA will continue to provide native habitat while also aiding in stormwater management for the industrial development. The intersection of the drainage channels with the Riparian Buffer and Undeveloped Floodplain ESAs is the subject of this AESA Plan. Pursuant to DDC Section 7.4.6, the disturbance of Undeveloped Floodplain is a permitted activity for the placement of this utility facility as long as the disturbed area is restored to minimize erosion and promote the recovery of the ESA. The mitigation activities offered as a part of this AESA would achieve this goal. Exeter -Martino Property AESA Report January 2021 5 Proposed Revegetation The developer is proposing to reseed the drainage control structures with a combination of native seed mixes. Each of the trees proposed to be removed are hardy species that are innately capable of rapid spread and growth. As an abundance of young, healthy representatives of each species (both trees and emerging saplings) will remain in the proximity of the impact areas, the removal of the five trees for the construction of the stormwater structures will cause minimal impacts to the overall habitat. It is expected that the removed trees will quickly be replaced from natural seed propagation following the completion of construction activities. While no tree plantings are proposed within the AESA, the removed caliper inches of the healthy trees are included in the overall tree mitigation and will be replaced through planted landscape trees in other portions of the development area. The proposed plantings will be shown in Landscape Plans to be submitted with the Construction Plans (CEP submittal) for staff review, comment, and approval. A combination of a Drainfield Mix and Riparian Restoration Mix of seeds will be seeded throughout the disturbed ESA areas to provide a protective ground cover and functional understory strata. The Drainfield mix is described as a grass mix designed for areas that have periodic moist soils, i.e. within drainage channels, that may retain moisture for 24 to 48 hours. The plants in this mix were included for their adaptability to a wide range of growing conditions. The Riparian Recovery mix is described as a combination of 36 native grass & wildflower species to aid in rebuilding stream bank buffer zones. The seed mixes include multiple native species including herbaceous species such as Eastern gamagrass (Tripsacum dactyloides) , switchgrass (Panicum virgat um) . and bushy bluestem (Andropogon glomeratus), A full list of the species included in both seed mixes can be found at Native American Seed (http://www.seedsource.com/catalog/). The Drainfield mix will be seeded within the center of the drainage channel while the Riparian Recovery mix will be seeded on the slopes and top of the channel. The goal of the proposed seeding is to develop an AESA with a quality, functioning native habitat that will not need additional maintenance beyond the initial seeding. The seed mixes will be sown in the spring or late fall, depending on the species. In the interim, temporary vegetative cover will be established by hydro-mulching or installing erosion control blankets. Irrigation is not proposed at this time; however, if the seeded forbs and grasses show signs of stress or the survival rate does not meet or exceed 90% cover, irrigation may be deemed necessary and installed following the plantings. An initial site visit by Kimley-Horn environmental staff will be performed following the completion of the seeding and prior to the first annual monitoring event. Kimley-Horn staff will perform additional site visits as necessary during the first annual monitoring period. Erosion Control Erosion control measures will be installed prior to the start of land disturbing activities on the project and will be installed in accordance with the approved plans and specifications. For the construction of the drainage structures, a rock check dam and silt fence win be utilized to protect the ESAs and prevent illicit discharges. Inspections shall be made weekly and after storm events to ensure the controls are functioning properly. If the control measures cannot manage erosion and offsite sedimentation, the plans will we revised and additional controls installed Proposed erosion control plans for the channels will be submitted with the CEP submittal for staff review, comment and approval. Exeter -Martino Property AESA Report January 2021 6 Compliance with Authorities The City of Denton is the authority over compliance with this AESA mitigation plan. Once the drainage structures have been constructed and the AESA mitigation activities have been completed, the City of Denton will be notified that the restoration activities have been completed. Annual Reporting The applicant will prepare an annual report each year for three consecutive years, beginning 12 months following the implementation of the mitigation activities, for the purposes of describing the cumulative mitigation work that has been performed during the reporting period, and to report on the current survivability of the seeding and preserved forest. These annual reports will be submitted to the City for review and inspection. The first two annual reports will contain action items that may include: the implementation of additional erosion control, re-seeding the seed mixtures as needed, removing weeds within the seeded areas, or removal of construction debris within the ESAs. Upon completion of the three-year monitoring and reporting period, the City of Denton Environmental Services shall inspect the plantings and determine whether ninety percent (90%) of the seeded area is healthy and has a reasonable chance of sustained cover. If it is determined that 90% of the seeded area is healthy and has a reasonable chance of sustained cover, the City will issue the final acceptance of the project. After city inspection, if more than 10% of seeded area is found to be diseased or not having a reasonable chance of sustained cover, the applicant shall be notified to reseed that problematic areas. If the applicant does not take remedial steps to bring the property into compliance, the City may use all legal remedies to enforce this provision. If changes need to be made to the mitigation plan during the three-year monitoring period, the City of Denton will be notified prior to making the plan modifications. Criteria for Approval The following outlines the criterial for approval of an AESA Plan and the project aspects that meet each criterion. 1.Mitigation goals are obtained by creating, expanding and/or improving ESAs. The proposed AESA proposes to mitigate the impacts to the Riparian Buffer and Undeveloped Floodplain ESAs from the construction of two stormwater control channels by seeding the channels and associated slopes with native seed mixtures to both provide a protective ground cover and functional understory strata. 2. Mitigation goals are obtained by preserving environmentally sensitive areas above the minimum requirements, exchanges between different types of ESAs, installing pollution prevention controls, and/or implementing best management practices or any other approaches that result in the improvement of the environment being impacted. Exeter -Martino Propedy AESA Report January 2021 7 Once revegetated, the AESA areas would continue to provide native habitat while also aiding in stormwater management for the industrial facility. 3. Areas offered as mitigation are linked to existing or planned open space or conserved areas to provide an overall open space system. The disturbances and proposed AESA are located within larger, openly forested ESAs surrounding an ephemeral stream and remnant channel. The impact areas are a fraction of the overall, undisturbed habitat onsite, and will be revegetated to avoid lasting negative impacts to the overall ecosystem. 4.Development is arranged for maximizing access and utilization of the ESAs by citizens. While the location of the current ESAs is not such to allow direct access to the public, the plan layout preserves the existing visibility to the onsite ESAs from Jim Christal Road and will provide additional visibility from the southwestern side of the facility. 5 Areas offered as mitigation are placed either in a lot or lots that incorporate a permanent conservation easement, restrictive covenants, or such other legal mechanism to allow for the long term conservation of said areas. Such legal mechanism shall limit any future land disturbing activity or construction within the ESAs ad shall run with the land and be binding upon all successors and assigns of the current owner. As the stormwater control structures are being revegetated to maintain the native habitat, the ESA designation will remain and therefore be subject to use restrictions set forth in the DDC. 6. The AESA plan shall demonstrate that the developer's alternative proposal results in a high-quality development meeting the intent of the standards in the DDC. The AESA has been designed to minimize the impacts to ESAs necessary to meet the stormwater design standards for the overall development and proposes to mitigate for the impacts by revegetating the constructed channels and associated slopes. As such the proposed development meets the criteria for approval for an AESA. Summary The impacts proposed to the Riparian Buffer ESA are 0.40-acres and to the Undeveloped Floodplain ESA are 0.53-acres, totaling 0.93-acres, resulting from the construction of drainage channels directing stormwater flow from outfalls to the adjacent stream channels. The mitigation for these impacts will consist of seeding the channel and associated slopes within the ESAs impacted by the construction with native seed mixtures to provide a protective ground cover and functional understory strata.

The remnant stream is depicted on both the USGS Topographic Map and on the NWI Map. Upon review of Google Earth images, the stream also appears to have been more defined in the past, but does not appear to currently carry consistent flows. Ponded water was observed in portions of the stream but were not flowing. This stream was previously assessed in 2015. The stream and associated buffer appears to be relatively unchanged since the assessment Conclusions Basedupon the site inspection by the City of Denton, the area in question is NOT an ESA reqiring 50 or 100 foot buffers and [ therefore is not subjected to the ESA requirements outlined in the Denton Development Cock. All other appropriate aspects of the Denton Development Code3 however, still apply. The official city ESA map will tx updated to remove the area from E; Based upon the site inspection by the City of Denton, the area in question IS an ESA and is subject to the re(Mrment set n forth in Section 17 of the Denton Development Co(b (if this tx)x is checked, fill out supplemental RMT form) n Based upon the site inspection by the City of Denton, insufficient information is available to determine the ESA status 1 of the area in question. A more extensive inspection is required from either the City of Denton or the property owner The determination of dre ESA status is permanently valid and may only be revisited if significant new information that necess itates a major change in the determination becomes available.

Based on the historical USGS Topographic Map and NWI Map it appears that surface water flow was previously through a remnant channel to the east. This stream was previously assessed in 2015. The stream and associated buffer appears to be relatively unchanged since the assessment Conclusions Based upon the site inspection by the City of Denton, the area in wnstion is NOT an ESA requiring 50 or 100 foot buffers and F-- therefore is not subjected to the EU requirements outlined in the Denton Development Co&. All other appropriate aspects of the Denton Development Code, however, still apply . The official city ESA map will tx updated to remove the area from b Based upon the site inspection by the City of Denton, the area in question IS an ESA and is subject to the requirment set n forth in kction 17 of the Denton Development Cock (if this tx)x is checked, fill out supplemental RSAT form) rB Based upon the site inspection by the City of Denton, insufficient information is available to determine the ESA status 1 of the area in question. A more extensive inspection is required from either the City of Denton or the property owner The determination of the ESA status is permanently valid and may only be revisited if significant new information that necess itates a major change in the determination becomes available. A request for reconsideration of the determination may be submitted in writing by the applicant, landowner, or agent within 30 days of the date below. dll/vw Signature of field investigator: Date :10/07/2020 Approval: Date :20201106 Supplemental RSAT Form DENTON Rapid Stream Assessment Techniques version 1 RSAT Evaluation Catego General Rating Categories and Associated Point Ranges Excellent Good Fair Poor Points 6-8 0-2 49-11 3-5 5-6 0-27-8 3-4 4 33-4 0-25-67-8 n/a0-23-45-67-8 0-26-7 2-34-5 0-27-8 5-6 73 1.
