From: Thompson, Mike [mailto:[email protected]] Sent: Tuesday, June 20, 2017 3:53 PM To: Tony LaColla Cc: David Hey Subject: EPC Comments for CPA 17-04, 05, 06, 07, 08, 09

Tony,

Attached are detailed EPC Staff comments for TA-CPA 17-06. Additionally staff comments for the other subject CPAs follow.

TA-CPA 17-07: Wetlands Management Division Wetlands on-site ( Hillsborough River). Any activity interfering with the integrity of wetland(s) or other surface water(s), such as clearing, excavating, draining or filling, without written authorization from the Executive Director of the EPC or authorized agent, pursuant to Section 1-11.07, Rules of the Commission, would be a violation of Section 17 of the Environmental Protection Act of Hillsborough County, Chapter 84-446, and Chapter 1-11, Rules of the EPC.

TA-CPA 17-09: Air Management Division The proposed amendment will place residential development next to other Heavy Industrial classified parcels, which can be a source of complaints (even when the facilities are operating in compliance). The parcel is the current site of a permitted air pollution source, Blacklidge Emulsions. If there is any information on where the facility will relocate, please share that information with EPC staff as they will most likely need an air construction permit if they are moving.

TA-CPA 17-04, 17-05, 17-08 NO COMMENTS

Let me know if you have any questions on these comments,

Sincerely,

Michael S. Thompson Project Manager Wetlands Management Division Environmental Protection Commission Of Hillsborough County (813) 627-2600 ext1219 [email protected]

STAFF REPORT ON C COMPREHENSIVE PLAN AMENDMENT

APPLICATION: CPA 17-06 HEARING DATE: AUGUST 14, 2017

CURRENT FUTURE LAND REQUESTED FUTURE LAND PROPERTY ADDRESS: USE: USE: 5105 West Tyson Avenue HI UMU-60

GENERAL DESCRIPTION OF SITE

The subject property contains 11.93± acres and is located in the South Tampa Planning District, in the Rattlesnake Point Waterfront Area. The property is currently zoned Industrial General (IG), which provides areas of light manufacturing, wholesaling, warehousing, assembly or product processing, heavy equipment and vehicular repairs and other light industrial uses. The industrial general district is established to provide areas for industry in locations, which are served by major transportation facilities and adequate utilities, but are not feasible, nor highly desirable for heavier industrial development because of proximity to residential, recreational, commercial or related developments. The district is to permit development compatible with uses of residential property adjoining or surrounding the district, with suitable open spaces, landscaping and parking area, which emits limited noise, odors, or light which can be detected on surrounding land. This district requires a minimum lot width of 50’ and a minimum lot area of 5,000 SF.

This site is surrounded by the following uses: a military training facility to the west, a boat storage facility to the south, vacant land to the east, and a yet to be developed mixed use project to the north across a channel of Old Tampa Bay. The character of the surrounding neighborhood is primarily industrial.

PROPOSED FUTURE LAND USE DESIGNATION The proposed future land use category of Urban Mixed Use-60 (UMU-60) would allow for the consideration of any of the allowable zoning districts from residential through commercial. It is important to review the current request in relation to those uses currently permitted and the intensification of the property that could occur if the future land use designation is changed to the UMU-60. Key city form characteristics for Urban Mixed Use include:  Blocks are small and rectangular, allowing for convenient pedestrian access from adjacent areas;  Lot sizes that are typically small and narrow, providing a fine-grained development pattern;  A mix of building heights, typically up to 10 stories, number of stories varies by location, special district or overlay district. Building height in local historic districts limited unless approved by the ARC (100 feet) or BLC (60 feet);  Building heights that step down to not more than one story higher at the property line than permitted in the adjacent neighborhood unless separated by a roadway, rail corridor, or other setback or buffer;  Buildings sited at or near the sidewalk along the primary street frontage and typically abut one another with limited side yard setbacks;  Building entrances set at the sidewalk along the primary street frontage;  Rear alleys and secondary streets that provide vehicular and service access, with limited driveways and curb cuts on a primary street;  Parking on-street, in individual or shared lots at the rear of structures, or in screened parking structures;  Transparent building frontages with pedestrian-scaled articulation and detailing;  Moderately wide sidewalks, with street trees, public seating areas, and inviting amenities;  Public streetscapes that serve as the area’s primary open space, complemented by semi- public plazas, courtyards and semi-public sidewalk dining areas; and *Any proposed development, city-wide may develop up to 2.75 FAR, if all of the following are met: o Subject site is greater than 0.5 acres; o Subject site maintains frontage on an arterial roadway (length of frontage must meet minimum lot width standard in City Code); and o Structure must have vertically integrated mix of at least 2 uses from 2 separate general use categories as outlined in City Code.

STAFF RECOMMENDATIONS City of Tampa Planning staff has reviewed this request and has the following objections. Staff finds the requested Urban Mixed Use-60 land use category INCONSISTENT with the following comprehensive plan goals, objectives, and policies: LU Objective 1.2: Create inspired urban design while respecting Tampa’s human scale, unique history, aesthetics, natural environment, and sense of community identity as the City changes and evolves.

LU Policy 1.2.3: Relate new buildings and development to the context of the neighborhood and community. This site is surrounded by heavy industrial land use categories which allow for manufacturing, research and development, flex space, industry incubators, professional office and similar heavy industrial uses. Residential development is prohibited. The requested UMU-60 will allow for high intensity/density residential, professional office and commercial development out of character and context with the surrounding neighborhood. LU Objective 8.9: Recognize industrial lands for their support to key economic engines within the City in order to strengthen Tampa’s role as a regional employment center.

LU Policy 8.9.2: Encourage the continued intensification, and existence of industrial, warehousing, and distribution facilities and provide opportunities for new warehousing/distribution activities in select locations, to provide a range of employment opportunities to Tampa’s residents.

LU Policy 8.9.3: Maintain industrial areas that provide for the manufacturing of goods, flex space, and research and development that are attractive, compatible with adjoining non-industrial uses, and well-maintained. The requested UMU-60 does not allow for industrial land uses. This land use category allows for non- industrial uses which are incompatible with existing uses of land on the peninsula. LU Objective 8.10: Preserve light and heavy industrial areas which are appropriately located in terms of traffic accessibility, minimizing their environmental effects on surrounding areas, and ensuring compatibility with surrounding land uses.

LU Policy 8.10.2: Residential uses within industrial land use categories are considered to be non- conforming uses.

Page 2

LU Policy 8.10.5: Heavy industrial uses shall have priority over other uses on undeveloped property appropriately designated as heavy industrial. Chemical Formulators, Inc., a heavy industrial use, remains in operation on the peninsula and is located near the western end. According to their web page, they “manufacture sodium hypochlorite in large quantities.” Sodium Hypochlorite is commonly known as “bleach,” and is offered to customers in tank sizes from 850 gallons to 10,000 gallons. They also package seven (7) other chemicals, including Chlorine, Sodium Hydroxide, Hydrochloric (Muriatic) Acid, Pool Acid, Sulfuric Acid, Sulfur Dioxide, Sodium Bisulfite, and a “line of water treatment products.” The Web Page and Material Safety Data Sheets for the chemicals identified above are included with this report. The requested UMU- 60 does not allow for industrial uses. This land use category allows for residential land uses which are inconsistent and incompatible with the existing heavy industrial land uses in close proximity to this site.

REVIEW CRITERIA FOR PLAN AMENDMENT REQUESTS

City Council must consider the following criteria as set forth in the City of Tampa Comprehensive Plan when deciding the request for a Comprehensive Plan Amendment; both staff’s professional opinion and factual information is provided in bold below:

1. The requested land use category does not meet the intent of the general character description of the City Form component in which it is being requested and is otherwise inconsistent with the Comprehensive Plan.

Per the Comprehensive Plan excerpts provided below, “Tampa’s specific ‘City Form’? (Pages 29 – 30)”, the proposed future land use change does not meet the intent of the City Form for this area within the South Tampa Planning District, the Gandy Sun Bay South neighborhood, and the Rattlesnake Point Waterfront Area.

As an urban city, Tampa has a defined city form that encompasses many components such as employment centers, urban villages, mixed-use corridors, mixed-use centers, transit stations, and neighborhoods. Elements of City Form: Development Components The physically built environment called the “City Form” has six (6) major components which are described below. The “City Form” includes the following:  Employment Centers  Urban Villages  Mixed-use Corridors  Mixed-use Centers  Transit Stations  Neighborhoods o Urban o Traditional o Suburban and Contemporary o The Waterfront

Tampa’s form is and will continue to be shaped by historical development patterns. The City has developed over the span of 150 years, and is influenced by the building patterns that occurred during three significant periods of time. 2. In approving any request for a land use category that provides for an increase in density, intensity or for a broader range of uses, than the existing land use category, City Council shall take into

Page 3

consideration and determine if:

a. a land use category of similar density or intensity is located on at least one (1) side of the subject site, and The closest site with the UMU-60 land use category is to the north, across a canal of Old Tampa Bay.

b. the subject site is within 1320’ (1/4 mile) of a designated transit stop or designated transit emphasis corridor, and There is not a transit emphasis corridor within ¼ mile of the site.

c. the subject parcel is located adjacent to a parcel which has a land use classification of R-6 or R-10, the subject site is located within 660’ (1/8 mile) of a designated transit stop or designated transit emphasis corridor. N/A. 3. In the event that City Council determines that the above criteria are not met, then City Council may deny the amendment or make a determination that the existing land use classification is no longer in the best interests of the public, it may approve the amendment or direct the local planning agency to propose an alternative amendment to the existing land use classification.

Based on the location of the subject site, the requested UMU-60 land use category is not in the best interest of this area and the City as a whole. This request allows for consideration of a maximum FAR of 3.5 (with bonus provisions). This site contains approximately 11.93 acres or 519,670 square feet (SF), this would allow for a structure which could contain a maximum of 1,818,949 SF and a typical building height of ten (10) stories. Similarly, with stand-alone residential development, a maximum density of 60 dwelling units per acre (with bonus provisions), a total of seven hundred fifteen (715) dwelling units could be developed. This modification would allow for high intensity/density residential, professional office and commercial uses out of character with the existing and planned development pattern for this area of the South Tampa Planning District and the Rattlesnake Point Waterfront Area.

Rattlesnake Point Waterfront Area has recently received City Council approval for a future land use amendment to Community Mixed Use-35 (CMU-35). This approval includes over half the parcels located within Rattlesnake Point. Although the CMU-35 category allows for a mix of residential and commercial uses, toxic/hazardous heavy industrial uses continue to operate on the peninsula. The requested UMU-60 allows for residential and commercial uses at a greater intensity/density, which is inconsistent with the existing heavy industrial uses on Rattlesnake Point Waterfront Area.

City staff is not supportive of the requested UMU-60 land use category. Due to City Council’s recent approval of CMU-35 for parcels located west and south of the subject parcel, if Council is inclined to approve this request, CMU-35 should be considered. The CMU-35 land use category would be consistent with the prior approval and provide a more appropriate scale, density and intensity in relation to the existing and planned development pattern. This category allows a maximum FAR of 2.0 (with density bonus) or a density of 35 dwelling units per acre (with density bonus). The maximum allowable intensity would be 1,039,342 SF or a density of four hundred seventeen (417) DUA. 3. If a land use is changed based on this criteria, the property owner shall process through a site plan district and, if provided for in the City’s land development regulations, shall meet the “Development Performance Incentive Criteria,” unless the development is within an approved Community Planning Area/Adopted Form Based Code Area, in which case a site plan zoning may not be required, as provided for in the specific plan in the land development regulations.

Hazard(s) not otherwise No OSHA defined hazard classes. Other hazards which do not result in classification: classified (HNOC) Toxic fumes, gases or YDSRUV may evolve on burning. Chlorine is extremely corrosive to most metals in the presence of moisture (> 150 ppm water and/or -40 degrees F dew point) or at high temperatures. Combines with water to produce hydrochloric and hypochlorous acid. Severe, short-term exposures may cause long-lasting respiratory effects, e.g. Reactive Airways Dysfunction (RADS), due to the material's severe irritating properties. Contact with liquefied gas might cause frostbites, in some cases with tissue damage. Direct contact with liquefied gas may cause frostbite and corrosive injury to the eyes. Supplemental information Keep away from heat. Make sure valves on gas cylinders are fully opened when gas is used. Open cylinder valve slowly to prevent rapid decompression and damage to valve seat. Use smallest possible amounts in designated areas with adequate ventilation. Liquid chlorine lines must have suitable expansion chambers between block valves due to high coefficient of expansion. Shut flow off at cylinder valve and not just at the regulator after use. Use a suitable hand truck to move cylinders; do not drag, roll, slide, or drop. Secure cylinders in an upright position at all times, close all valves when not in use. Establish written emergency plan and special training where chlorine is used. Regularly inspect and test piping and containers used for chlorine service. 3.

Never give anything by mouth to a victim who is unconscious or is having convulsions.

Material name: Chlorine SDS US $8& Version #: 01 Issue date: 01-07-2015 2 / 12 Most important Fatal if inhaled. Immediately dangerous to life or health (IDLH) at 10 ppm. May cause severe symptoms/effects, acute and irritation to the nose, throat, and respiratory tract. Symptoms may include coughing, choking and delayed wheezing. Could also cause tightness in the chest, a blue discolouration of the skin (cyanosis), severe headache, nausea, vomiting and fainting. Inhalation could result in pulmonary edema (fluid accumulation). Symptoms of pulmonary edema (chest pain, shortness of breath) may be delayed. May result in unconsciousness and possibly death. Severe, short-term exposures may cause long-lasting respiratory effects, e.g. Reactive Airways Dysfunction (RADS), due to the material's severe irritating properties. With this condition, asthma-like symptoms and increased reactivity of the airways is experienced. Direct skin contact may cause corrosive skin burns, deep ulcerations and possibly permanent scarring. If product is sprayed directly on skin, symptoms of frostbite may be experienced including numbness, prickling and itching. Corrosive to the eyes and may cause severe damage including blindness. Symptoms may include stinging, tearing, redness, swelling, and blurred vision. If product is sprayed directly into the eyes, could cause freezing of the eye. Indication of immediate Immediate medical attention is required. Fatal if inhaled. Causes chemical burns. Symptoms may medical attention and special be delayed. Keep victim under observation. Medical supervision for minimum 48 hours. Provide treatment needed general supportive measures and treat symptomatically. General information First-aid procedures should be reviewed by appropriate personnel familiar with chlorine and its conditions of use in the workplace. Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves. Show this safety data sheet to the doctor in attendance. 5. Fire-fighting measures Suitable extinguishing media Extinguishing media - small fires: Dry chemicals. Carbon dioxide (CO2). Extinguishing media - large fires: Water Spray or Fog. Foam. Unsuitable extinguishing Use water with caution. May react with water. Do not use GLUHFWZDWHUVSUD\RUwater jet as an media extinguisher, as this willspread the fire. Specific hazards arising from Pressurized container may explode when exposed to heat or flame. May react to cause fire and or the chemical explosion upon contact with many organic compounds, ammonia, hydrogen and with many metals at elevated temperatures. Chlorine will support the burning of most combustible materials. Combines with water to produce hydrochloric and hypochlorous acid. Liquefied chlorine can accumulate static charge by flow or agitation, since it has a very low electrical conductivity. Chlorine containers or cylinders may vent rapidly or rupture violently, if exposed to fire or excessive heat for a sufficient period of time. Intense local heat (above 200 deg C) on the steel walls of chlorine cylinders can cause an iron/chlorine fire resulting in rupture of the container. Vapors are heavier than air and may spread along floors. Toxic fumes, gases or YDSRUV may evolve on burning. Special protective equipment Firefighters should wear full protective clothing including self contained breathing apparatus. and precautions for firefighters Firefighters must use standard protective equipment including flame retardant coat, helmet with face shield, gloves, rubber boots, and in enclosed spaces, SCBA. A full-body chemical resistant suit should be worn. Fire fighting Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Move equipment/instructions containers from fire area if you can do so without risk. Remove combustible materials. Stop the flow of gas before extinguishing fire, if safe to do so. Use water spray to direct escaping gas away from workers if it is necessary to stop the flow of gas. Cool containers exposed to heat with water spray and remove container, if no risk is involved. Stay away from ends of cylinders and withdraw immediately in case of rising sounds or discolouration of containers. Do not allow run-off from fire fighting to enter drains or water courses. Dike for water control. Specific methods Use standard firefighting procedures and consider the hazards of other involved materials. General fire hazards The product itself does not burn. However, material is considered to be an oxidizing gas. Supporter of combustion and can intensify a fire. Hazardous combustion Toxic chemicals are formed when combustible materials burn in chlorine. These may include products corrosive hydrogen chloride gas and other chlorine compounds. 6. Accidental release measures Personal precautions, Restrict access to area until completion of clean-up. Keep unnecessary personnel away. Keep protective equipment and people away from and upwind of spill/leak. Consider initial downwind evacuation for at least 500 emergency procedures meters (1/3 mile). Ensure clean-up is conducted by trained personnel only. Ventilate closed spaces before entering them. Many gases are heavier than air and will spread along ground and collect in low or confined areas (sewers, basements, tanks). Eliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Wear appropriate protective equipment and clothing during clean-up. For personal protection, see section 8 of the SDS.

Material name: Chlorine SDS US $8& Version #: 01 Issue date: 01-07-2015 3 / 12 Methods and materials for Stop the flow of material, if this is without risk. Use only non-sparking tools. Keep combustibles containment and cleaning up (wood, paper, oil, etc.) away from spilled material. Remove or isolate incompatible materials as well as other hazardous materials. Do not spray leak with water since a reaction producing corrosive hypochlorous and hydrochloric acids occurs, which can aggravate the leak.

May be absorbed and neutralized into solutions of caustic soda, or lime and placed in polypropylene, polyvinyl chloride, fibreglass or lead containers. Since hypochlorites are formed, the solutions must be treated with a reducing agent such as sodium sulfite before disposal. Do not immerse container in caustic solution.

Large Spills: Large uncontrollable leaks require environmental considerations and possible evacuation of the surrounding area. When possible draw off chlorine to process or disposal system . Contact the proper local authorities.

For waste disposal, see section 13 of the SDS. Environmental precautions Avoid release to the environment. Prevent entry into waterways, sewer, basements or confined areas. Contact local authorities in case of spillage to drain/aquatic environment. 7. Handling and storage Precautions for safe handling Establish written emergency plan and special training where chlorine is used.

Use only outdoors or in a well-ventilated area. Wear respiratory protection. Wear protective gloves/clothing and eye/face protection. See Section 8 of the SDS for Personal Protective Equipment. Do not breathe gas. Avoid contact with eyes, skin, and clothing. Regularly inspect and test piping and containers used for chlorine service. Liquid chlorine lines must have suitable expansion chambers between block valves due to high coefficient of expansion. Keep away from heat. Keep/Store away from clothing and other combustible materials. Keep reduction valves free from grease and oil. Use only chlorine compatible lubricants. Use smallest possible amounts in designated areas with adequate ventilation. Shut flow off at cylinder valve and not just at the regulator after use. Use a suitable hand truck to move cylinders; do not drag, roll, slide, or drop. Protect against physical damage. Wash hands after handling and before eating. Conditions for safe storage, Store in steel pressure cylinders in a cool, dry area outdoors or in well-ventilated, detached or including any incompatibilities segregated areas of non-combustible construction. Keep container tightly closed. Store locked up. Protect from sunlight. Storage area should be clearly identified, clear of obstruction and accessible only to trained and authorized personnel. Do not store near combustible materials. Wood and other organic materials should not be used on floors, structural materials, or ventilation systems in the storage area. Store away from incompatible materials (see Section 10 of the SDS). Secure cylinders in an upright position at all times, close all valves when not in use. Use a "first in - first out" inventory system to prevent full cylinders from being stored for excessive periods of time. Store at temperatures not exceeding 55°C (131°F). For the specified temperature the system pressure is 225 psig (1551 kPa). 8. Exposure controls/personal protection Occupational exposure limits US.

Re: City of Tampa Comprehensive Plan Amendment TPA/CPA 17-06 5105 West Tyson Avenue (131227.0000)

Amendment TPA/CPA 17-06 would convert an 11.93 acre parcel from Heavy Industrial (HI) to Urban Mixed Use 60 (UMU-60). Up to seven hundred and fifteen (715) dwelling units could potentially be developed on the site. Based on adopted Student Generation Rates the amendment could potentially generate ninety-one (91) students in the kindergarten through 5th grade level, forty-six (46) students at the 6th through 8th grade level, and forty-seven (47) students at the high school level. Per the Department of Education’s Capital Outlay Full Time Equivalent (COFTE) projections, all of the impacted schools are projected to have capacity in the next 5 years with the exception of the high school. However, an addition at Robinson High School will increase the capacity by 285, which is planned to open for the 2018-19 school year.
