Environmental Land Solutions, LLC Landscape Architecture & Environmental Planning 8 Knight Street, Suite 203, Norwalk, CT 06851 Tel: (203) 855-7879 Fax: (203) 855-7836 March 17, 2021 Zoning Commission City of Norwalk 125 East Avenue Norwalk, CT 06856-5125 Re: Application for CAM Short Form 72 Shorefront Road, Norwalk, CT Dear Commission Members: Shorefront Park Properties, LLC is proposing to develop the existing vacant property with a new residence at the above referenced address. The property lies within the coastal zone due to its proximity to the reaches of the tidally-influenced of Long Island Sound. The proposed work will occur within Coastal Boundary of Long Island Sound and accordingly, an application for CAM Short Form is being submitted to the City Zoning Commission for review and approval. The property fronts on tidal waters of Long Island Sound within the Norwalk Harbor. Environmental Land Solutions, LLC (ELS) has been authorized to prepare this CAM report for the project. This report is based on a site inspection made on July 29, 2020, review of the survey prepared by Ryan and Faulds, Land Surveyor, entitled “Zoning Location Survey,” proposed for 72 Shorefront Road, dated 3/4/21, “Proposed New Construction- Grading and Drainage Plan,” “Proposed New Construction - Erosion Control Plan,” both dated 2/2/21 and a “Drainage Analysis,” dated 3/10/21, prepared by Peak Engineers, LLC, and a building plan set prepared by Peters D. Designs, LLC, date dated 3/10/21. Information referenced herein has been excerpted from the Department of Environmental Protection (DEEP) Office of Long Island Sound Programs (OLISP) publication Reference Guide to Coastal Policies and Definitions, revised 07/26/99, and the General Statutes of Connecticut (CGS), Volume 8, revised to January 1, 2001. The City of Norwalk Zoning Regulations were also reviewed. A. DESCRIPTION OF EXISTING CONDITIONS The subject property is 10,110 sf or 0.23± acres in area. The site fronts on the southeastern end Shorefront Park Road. The existing property is undeveloped with a near level lawn area and one 36" diameter breast height Copper Beech tree. The property is located in the B- Residential Zone with surrounding residential homes to the north, south and west. Along the perimeter of the maintained lawn area of the site, an existing retaining wall defines the developed site areas. The property extends to the Mean High Water line, approximately 30'± waterward of the seawall. The site will be serviced by public water and sewer. 1
The topography of the site is gently sloping toward the water. The existing site elevations range from 10.3'± at the southwest corner to 8.2'± along the top of the seawall. The bottom of the seawall runs along elevation 5.0'±, and extends to MHW line of 3.3'± east of the seawall (NAVD ‘88). Existing flood zone elevations include VE Zone (el. 14.0) along the eastern side of the site, and the AE Zone (el. 11.0) over the remainder of the site. The site’s upland vegetation is generally limited to lawn and the Copper Beech located near the center of the site. Tidal Wetlands: Tidal wetland areas, found to the east of the existing retaining wall, are dominated by high marsh vegetation including Saltmeadow Cordgrass (Spartina patens), Spike Grass (Distichlis spicata), Blackgrass (Juncus gerardi), Sea Lavender (Limonium carolinianum), and High-tide Bush (Iva frutescens). Saltwater Cordgrass (Spartina alterniflora) is found along the lower tidal areas to the north. The site’s shoreline is within the DEEP’s Natural Diversity Data Base highlighted area (December 2020) for Norwalk, but does not include any critical habitat areas. The lack of any significant upland onsite natural or vegetated areas makes the upland portions of the site of little value to wildlife. Within the wetland a Yellow-crowned Night Heron observed during the site visit. This bird is on the DEEP (2015) list for Species of Special Concern European starlings and House Sparrows were also seen on the site. The site’s tidal marshlands, open water, and mudflats, provide valuable habitat for wildlife such as the Great Egret, Northen Diamondback Terrapins, and finfish. There are no any significant cultural or historic resources on or immediately adjacent to the site. The site is adjacent to the closed areas of the Norwalk Recreation Shellfishing Beds within the Norwalk Harbor. B. DESCRIPTION OF PROPOSED PROJECT The proposed site improvements include a new residential dwelling at the center of the site. The Drainage Plan proposes two underground infiltrator galleries, one beneath the new driveway, and a second below the rear patio. Together these will provide water quality treatment for the first inch of rainfall from impervious surfaces. The finish floor elevation of the dwelling will be set at 12.2', 1.2' above the 11.0' minimum flood hazard elevation (AE) zone. The proposed grades around the new residence will be slightly raised to provide positive drainage from the building. Excess soil generated from excavation will be removed from the site during construction. The proposed building will be serviced by public water and sewer services. C. DESCRIPTION OF COASTAL RESOURCES The following coastal resources are located on the site: 2
General Resources - the coastal waters of the state, their natural resources, related marine and wildlife habitat and adjacent shorelands, both developed and undeveloped, that together form an integrated terrestrial and estuarine ecosystem. Tidal Wetlands - means “wetlands” as defined by CGS Section 22a-29 (2) revised to January 1, 2001. Tidal wetlands are located on the southern portion of the site as described above. Coastal Hazard Areas - means those land areas inundated during coastal storm events or subject to erosion induced by such events, including flood hazard areas as defined and determined by the National Flood Insurance Act, as amended (USC 42 Section 4101, P.L. 93-234) and all erosion hazard areas as determined by the (DEEP) commissioner. The VE (el. 14.0') and AE (el. 11.0') Zones overlap the property. The following coastal resources are located adjacent on the site: Intertidal Flats - means very gently sloping or flat areas located between high and low tides of muddy, silty and fine sandy sediments and generally devoid of vegetation. These areas are located off the site. Shorelands - means those land areas within the coastal boundary exclusive of coastal hazard areas, which are not subject to dynamic coastal processes and which comprise typical upland features such as bedrock hills, till hills and drumlins. Shellfish Concentration Areas - means actual, potential or historic areas in coastal waters, in which one or more species of shellfish aggregate. This resource is located to east within the Norwalk Harbor. However, these beds are closed to recreational use. D. SUITABILITY OF THE PROJECT FOR THE PROPOSED SITE The coastal resources as described above will not be impacted by the proposed redevelopment of this property mainly because the proposed activities will occur within the presently developed area of the site. There will be no encroachment into coastal resources on the site or in the surrounding resourse area. Consistency with Applicable Coastal Use Policies: General Resources - to preserve and enhance coastal resources in accordance with the coastal policies. The development of this lot will occur within the presently developed area and therefore is not expected to significantly disrupt either the natural environment or sound economic growth. Sewer and Water Lines - to locate and phase sewer and water lines, so as to encourage concentrated development in areas which are suitable for development. The property is 3
presently served by a municipal sewer and water and will continue to be after redevelopment. Consistency With Coastal Resources: The following coastal use policies are applicable to the property: General Resource - the proposed development is consistent with the surrounding residential neighborhood. There will be no change in the distance to tidal waters from developed areas. General Development - the subject property lies within a developed residential zone. The proposed development of this lot as planned will not adversely impact sound economic growth. Coastal Hazard Areas - development in the coastal hazard area will be accomplished in a manner to minimize hazards to life and property. The new building will be located only in the AE flood zone and have a finished floor set at 12.2', 1.2' above the elevation of the (AE) zone is 11' NAVD ‘88. There is no work proposed within the (VE) zone of the property. Tidal Wetlands - All construction activities are located away from tidal vegetation. No direct or indirect impacts to tidal wetlands are anticipated as a result from this project. The project is consistent with this coastal resource policy. Shellfish Concentration Areas - means actual, potential or historic areas in coastal waters, in which one or more species of shellfish aggregate. This resource is located to east within the Norwalk Harbor. However, these beds are closed to recreational use. E. POTENTIAL BENEFITS AND ADVERSE IMPACTS OF THE PROJECT: The proposed redevelopment and site improvements will occur within areas presently maintained and developed. During construction, the proper installation and maintenance of sediment and erosion controls will provide protection from transport of erosion to coastal waters (refer to plans prepared by Peak Engineers, LLC). Storm flows from the roof leaders and a paved driveway will be directed to underground infiltrators, maintaining water infiltration to the adjoining soil areas. The Drainage Analysis notes that the “drainage report has been prepared to follow the City of Norwalk Drainage Manual, date June 1, 2017". No adverse impacts to the coastal resources are anticipated with the proposed site development. The project is consistent with the adjacent land uses and existing zoning. F. SUMMARY In summary, the property involved in the proposed redevelopment includes a new 4
residence and new bituminous pavement. There are several natural coastal resources found within the property. However, the proposed site plans have been developed to provide Best Management Practices designed to prevent significant alteration of existing drainage patterns, increase the hazard of coastal flooding, degrade the visual quality of the surrounding natural resources, or disturb the tidal wetlands. The proposed development is consistent with the Coastal Area Management (CAM) goals and policies and will not have any adverse impacts to coastal resources.
