COMMON FLOOD ISSUES -

SURVEY RESULTS

Through the execution and analysis of a public survey of over 4,000 people (via letters, emails, and postcards, with 55 responses) and through site visits to over 500 individual homes, the Calibre team developed a list of the most commonly noted flood-related issues. We cataloged over 400 citizen photos, mapped more than 50 flooding locations, hosted a public meeting to discuss floodproofing and risks, and contacted nearly 45 individual citizens to discuss risks.

The main flood concerns identified by the survey and site walks are summarized by the interactive Google Map at right.

The lists below describe the types of flooding and flood concerns identified by the surveys and site walks, as well as other noted flood-related discussion drawn from the surveys and interaction with citizens.

FOUNDATION FLOODING

  • Water seeped into basement through foundation

  • Foundational settling

  • From the ground up seepage

Specific Flood Concerns

  • Flooding in the street, high above curb and into our lawn

YARD/STREET FLOODING

INTERACTIVE MAP: REPORTED FLOODING & RELATED PROBLEMS

This interactive map shows key locations of flooding as determined by modeling, citizen input, and City records. It also includes images, comments about flooding, basin boundaries, and other relevant information. This map can be used to see how reported flooding relates to the Areas of Probable Flooding in the 100-Year Event and to see where different citizens have been reporting flooding throughout the basin areas.

The images below were provided by citizens of Englewood and/or the City of Englewood in response to the survey discussed herein.  Credits can be found at the bottom of this page.

Specific Areas of Flooding

During the course of this study, several homeowners were met in-person at their homes to discuss flooding issues and current floodproofing methods. A few of the most notable items are outlined below.

Individual Homeowner Flooding

2900 Block of Ogden 

The residents at this location have lived at the property for 43 years. 

  • Flooding has only occurred in the past 11 years, getting worse as more development is finished to the southeast of this property

  • The owner before the current resident had built a tasteful brick wall around the back of the house to protect the ground-level windows from water

  • Flooding occurs at this property mainly because of a lack of drainage in the back alley. There is an inlet in the alley behind the house that is insufficient

  • In recent years, two additional storm lines have been installed to deposit runoff into the inlet box in front of this property

  • The resident noted that if the two additional lines had run directly into the inlet across the street, the outlet pipe is bigger and would likely handle the additional flows, as opposed to the smaller pipe within the inlet box directly in front of the property

  • A neighbor to the south had built a concrete wall around the back of the property in the past; after the wall was built, the residents at 2960 S Ogden noted higher flooding depths (up to 10" more than previous floods)

  • This resident noted upwards of 40" of water in the garage during the large storm event of 2018

4600 Block of acoma 

The owner of this location usually rents the property to two sets of tenants, one in the upstairs area and one set in the basement.

  • The recent flooding in 2018 rendered the basement uninhabitable. Renovations are ongoing.

  • The upstairs area was not impacted

  • Water broke one egress window and one other window into the basement, flooding the area to the ceiling; the resident was able to escape before the water got too high

  • All carpeting, drywall, furniture, wiring and plumbing is being renovated to mitigate damage due to the floods

  • The stairwell to the basement also flooded, eventually leaving the basement filled with water during the flood

  • A small step had been built around the stairwell that would keep out smaller floods, but this home experienced nearly 3.5' of flooding

1200 Block of radcliff

The residents at this location have lived at this property for 32 years.

  • The recent flood cause tens of thousands of dollars in damages to cars, furniture, carpeting and other household appliances

  • This house does not have a basement, just a main level

  • The main level of the house sustained flooding due to minor gaps in the wall-foundation connection 

  • The large 8' fence adjacent to the property was knocked down due to the force of the water

  • The garage door and other fencing was damaged due to water force as well

  • This resident also noted that nearby new developments have been associated with higher and more common flooding

100 Block of e cornell

  • Flooding is localized in this area to this specific property

  • Water flows through and over a retaining wall from the neighbor's house to the east

  • Resident noted that during high floods, oil sheens can be seen on the top of the flood waters and gas smells come from a mist off of the floodwaters

  • Resident noted that the storm grates out front in the cult-a-sac tend to get clogged very easily, rendering them not as useful as they could be
