The project will complete construction of the southern half of Duchess Drive which will provide access to the site. The subject property consists primarily of a mixture of young forest and open areas with invasive exotic species present, primarily Chinese Privet. A tributary of Pecan Creek flows through the site in a south- easterly direction. A Rapid Stream Assessment found the stream to be in good condition. In October of 2019 City of Denton staff performed an ESA assessment of the property (ESA19-0030). A 50 foot Riparian Stream buffer was identified on both sides of the stream. Additionally some Cross Timbers Upland Habitat was identified overlaying the Riparian Buffer ESA as well as some Undeveloped Floodplain ESA. The Undeveloped Floodplain ESA is contained entirely within the Riparian Buffer ESA. Water Related ESA was determined not to be present. The purpose of this Alternative Environmentally Sensitive Area Plan is to propose mitigation to impacts to the Riparian Buffer ESA caused by the construction of residential roadways to cross a tributary of Pecan Creek in two locations and for impacts to the Riparian Buffer caused by the construction of a storm drain. Impact to the Undeveloped Floodplain ESA is limited to the construction of the culvert of the southern roadway and is a permitted disturbance as outlined in DDC 7.4.6B.1.o. No additional impacts are proposed to the Cross Timbers Upland Habitat other than what is permitted by DDC 7.4.8A.1. Additional project information is available from the City of Denton case files for ESA19-0030 and PP19- 0038. Notification An approval of the AESA will be required for the proposed deviations from DDC.7.4 for Riparian Buffer ESA and Undeveloped Floodplain ESA. Nationwide Permit (NWP) 14 – Linear Transportation should authorize the proposed crossing which does not require Preconstruction Notification to the Corps. Affected Riparian Buffer ESA, Cross Timbers Upland Habitat, and Undeveloped Floodplain ESA Impacts Attached exhibit EH-1 shows all ESA/Habitat boundaries overlaid on one exhibit for reference. Attached exhibit AESA-1 shows the Riparian Stream Buffer ESA and the proposed crossings of the tributary. The proposed impacts are associated with the required residential street ROW of 60’ and utility/DME easement of 8’ needed to build 3 box culverts as shown. One storm drainage outfall to the creek and a corner of Lot 3, Blk B impacts are also anticipated and shown on AESA-1. The proposed Riparian Buffer ESA removal is limited to a total of 20,900 SF in the four locations as shown on AESA-1 and summarized in the ESA and Mitigation Area Summary Table – Table 1. Lot 18, Blk A will be an HOA lot and Riparian Buffer and Cross Timbers Upland Habitat preserved. The vegetation within the proposed impact area includes a combination of native and invasive species. Dominant tree species include Post Oak, Shumard Oak, Blackjack Oak, Eastern Red Cedar, Cedar Elm, Chinese Privet, and Fringed Green Briar. Chinese Privet is the dominant invasive understory species with approximately 50% coverage. The AESA-1 exhibit also shows a Natural Preserve of 5,560 acres of land on Lot 17 that will be set aside for tree preservation. Cross Timbers Upland Habitat protection requirements will not apply to this area as the understory is not being protected. Attached exhibit CTU-1 shows Cross Timbers Upland Habitat on the site. As shown on the exhibit, 163,633 SF of Cross Timbers Upland Habitat is identified of which 115,944 SF will be preserved. This is approximately 71 % Cross Timbers Upland Habit preservation which is well above the required 50% preservation. Attached Exhibit UFP-1 shows the Undeveloped Floodplain ESA which is entirely contained within the limits of the Riparian Buffer ESA. Of the 7,956 SF of Undeveloped Floodplain ESA shown on the site 2,608 SF will be removed and is a permitted disturbance as outlined in DDC 7.4.6B.1.o. Preliminary Plat and Engineering Approval The Preliminary Plat approval process requires the submission and approval of extensive engineering information including Floodplain Study, Downstream Stream Assessment, Drainage Analysis, Storm Sewer Design, Utility Design, Roadway Design, Culvert Sizing etc. (See Preliminary Plat Submittal/Approval requirements of the City of Denton). With the approval of the Preliminary Plat (PP19-0038) these requirements were met and approved. The Stream Assessment and floodplain study demonstrate no adverse impacts to/on adjacent properties. If the CEP requires a modification of the AESA, a revised AESA will be prepared and an application in accordance with DDC Section 2.8.4 will be submitted prior to a final plat application. Mitigation 1) Upland Habitat Protection and Land Dedication: Dedicate an additional 52,090 SF of land adjacent to the existing Riparian Buffer ESA for habitat development (See exhibit AESA-1 for dedicated area). It is proposed that due to the large number of smaller desirable native species (Post Oak, etc) already growing on this land that the area will be selectively hand cleared of invasive species. No additional planting is proposed as the removal of invasive species (Chinese Privet) will allow the dense population of smaller native species already growing (and that will generate naturally) opportunity to flourish. 2) Riparian Buffer Preservation and Invasive Species Removal: Targeted Chinese privet removal methods outlined by others (The Texas Invasive Plant and Pest Council, https://www.texasinvasives.org) will be used as a guide in finalizing removal methods. Removal methods and activities will be coordinated with Environmental Services staff and will be done in a manner that will minimize impacts to native vegetation. Heavy invasive species removal areas that would benefit from over seeding with an appropriate native grass seed mixture will have the seed mixture applied after removal. Approximately one year after initial removal the removal areas will be re-visited and any regeneration of the invasive species will be removed in the same manor. Due to the dense population of desirable species in the Riparian ESA, removal of invasive species will allow an even more vigorous opportunity for desirable species to thrive. 3) Areas disturbed for construction: To restore the function of the Riparian Buffer ESA all areas disturbed during construction including any disturbed area for the installation of the storm outfall will be treated with an application of native seed mix. The storm outfall with its narrow, linear construction footprint will be located to avoid existing trees in the Riparian Buffer ESA. Treating any construction disturbance with a native seed mix will provide Riparian Buffer restoration and allow native species an opportunity to thrive. 4) Riparian Buffer and Mitigation Area Preservation: The entire Riparian preserved area and proposed mitigation area will be dedicated to the HOA for preservation. This dedication area is designated by lot and block on the approved preliminary plat (Lots: 2A, 17A, 2B). The area will be designated as a “Gro-Zone” and Gro Zone signs (See Exhibit AESA-2) will be placed as shown on exhibit AESA-1. In addition one educational “Cross Timbers Ecoregion” sign (see exhibit AESA-3) will be placed to be visible from a roadway in a location selected to be appropriate after the completion of construction when a prominently visible location not destructive to vegetation can be determined along Saddle Lane where it is adjacent to the mitigation area (see exhibit AESA-1). Note: 1) Installation and maintenance of proposed revegetation is the responsibility of the property owner for a period of three years. Annual observation and reporting to City staff will be performed of the cumulative mitigation work and any issues with survivability of plantings identified for staff review and inspection for the first three years. After 3 years Environmental Services shall inspect for confirmation that the project has achieved a final 90% native vegetation ground cover. 2) Native grass seed mix used to apply to disturbed Riparian Buffer ESA to be 25% each Sideoats Gama and Wilman Lovegrass, 15% Switchgrass, 10% each Green Sprangletop, Indian Grass, and Little Bluestem, and 5% Big Bluestem or an equivalent mix appropriate for the specific soil type and exposure discovered at the time of application. Any modifications to seed mix shall be confirmed as appropriate and acceptable with Environmental Services staff prior to application.
