NAMPA — After holding off a decision for a month, Nampa City Council approved major increases to the city’s impact fees Monday night.

The fees, which will take effect this summer, will increase rates for developers by anywhere from 99 percent to 855 percent. The additional funds from the fees will go to several city departments to mitigate the strains of growth within Nampa.

The City Council was scheduled to approve the amended ordinance on Feb. 4, but Mayor Debbie Kling said the city delayed the decision to allow employees time to draft the appropriate language for the ordinance.

Developers pay impact fees when building new residential or commercial developments. This revenue helps the city maintain levels of service for police, fire, parks and roads as the population grows.

Nampa’s population growth is slated to cost the city $255 million over 10 years in police, fire, parks and streets, Anne Wescott with Galena Consulting said at a City Council meeting in October. Nampa’s current impact fees are not enough to cover the anticipated needs over that period.

Wescott told officials that Nampa could collect nearly $7 million in impact fees each year to fund growth-related needs. Over 10 years, that would generate $70 million to go toward the $255 million growth costs, largely for streets.

The impact fee recommendations, according to the Galena Consulting report, are:

  • $5,459 per single-family dwelling unit, up from $1,806
  • $4,266 for a multifamily dwelling unit, up from $1,662
  • $7.34 per square foot for a retail development, up from $3.69
  • $4.73 per square foot for an office development, up from 60 cents
  • $2.01 per square foot for an industrial development, up from 21 cents

These increases would help cover a new police facility and additional patrol vehicles, three new parks, two new fire stations and dozens of street projects over the next 10 years, among other things.

Wescott said there is a 120-day period in place before the new fees take effect to give existing developers time to pull the permits they need. The new impact fees won’t be implemented until July.
